Ban on hunting takes effect
Gabriel Amoah , 05/08/2008
Statistics available to The Statesman in Kumasi from the Wildlife Division of the Forestry Commission reveals that annual volume of bush meat estimated at 384,992 tons valued at 350 million dollars is harvested in Ghana as against the total annual consumption which also estimated at 225,287 tons and valued at 205 million dollars.

Hunting reduces recruitment of primate-dispersed trees
Gabriela Nunez-Iturria,1, Ola Olssonb, Henry F. Howea,c,*
Hunting with firearms decimates primates of large and medium body size (>2 kg) that disperse the seeds of large-seeded trees. In continuous, un-fragmented forests of southeastern Peru regularly hunted with firearms for 30-40 years, large primates are extirpated and medium-sized (medium) primates are reduced 61% compared with protected forests. At hunted sites seedlings and small juveniles (<1m height) of trees dispersed by primates heavier than 2 kg are reduced 46%, a loss of one species m2, and abiotically-dispersed plants are 284% more common, adding eight individuals m2, compared with protected forests. Here we provide evidence consistent with the long-held prediction that commercial hunting changes plant communities. We show that the composition of seedling and small juvenile tree communities that ultimately regenerate future forests differs markedly in forests hunted with firearms compared with protected forests. This opens the possibility of shifts in tree species composition, even in hunted forests that are not logged or fragmented, towards forests dominated by trees dispersed by wind or non-game animals. 18/06/2008 Click here to read on... |

The processes for releasing a zoo-bred Sumatran orang-utan Pongo abelii at Bukit Tigapuluh National Park, Jambi, Sumatra
Perth Zoo released a sub-adult Š Sumatran orang-utan Pongo abelii in November 2006 into the protected Bukit Tigapuluh National Park in Jambi, Sumatra, where the Sumatran Orang-utan Conservation Programme (SOCP) is trying to re-establish an orang-utan population. This was the first release of a captive-born orang-utan into the wild. Temara is being closely tracked and monitored by Perth Zoo and SOCP staff. The aim is that she will be followed for at least 2 years. This paper describes: the pre-release preparation, the release process, the benefits of the programme, the monitoring process and the post-release results. 07/04/2008 Click here to read on... |

Palm oil: Addressing issues and towards sustainable development
The quest for renewable energy has intensified since the escalating price of crude petroleum in the recent years. Renewable energy such as biodiesel has the potential to replace petroleum-derived transportation fuel in the future. Biodiesel is defined as the mono-alkyl esters of long-chain fatty acids derived from vegetable oils such palm oil, rapeseed and soybean. Currently, more than 80% of the world biodiesel productions are from rapeseed oil. However, the cost of palm oil which is at least US$ 200 per tonne cheaper than rapeseed oil indicates that palm oil could be a more suitable and attractive candidate as the source of biodiesel compared to other vegetable oils. Although palm oil is known to be a multi-purpose vegetable oil with products ranging from food to biodiesel, there are a lot of issues surrounding palm oil production. Nevertheless, some of these issues reported in the literature were found to be misleading and are thus confusing the public perception on palm oil. Thus, the aim of this paper is to highlight and clarify the negative issues reported in the literature surrounding palm oil production. Apart from that, various policies or/and strategies that will lead to a more sustainable production and development of palm oil industries will also be proposed. Hence, palm oil will be able to become the leading vegetable oil in terms of food and non-food production, especially as the main source of renewable energy, biodiesel. 01/10/2007 Click here to read on... |

Putting orang-utan population trends into perspective
Is it true that "the orang-utan could be virtually extinct within five years", as reported by [1] in a recent issue of Current Biology? The dire conservation status of this ape warrants a sense of urgency [2], but we would like to present a more balanced view and highlight the emergence of some positive trends.

Response to the statement of the EU Scientific Steering Committee on the use of non-human primates (NHP) in biomedical research
The European Union's Scientific Steering Committee (SSC) produced a scientific opinion paper in 2002 on the use of non-human primates (NHP) in biomedical research. This paper made a series of statements about scientific research on NHP, and it has informed the EU's decision-making process on the matter. In our new report we address each of the statements made by the SSC. We discuss current scientific opinion on the issues raised, and the scientific basis for adopting non-animal alternatives in biomedical research. 12/07/2007 Click here to read on... |

Modelling the impact of Ebola and Bushmeat Hunting on Western Lowland Gorillas
The 2003 outbreak of Ebola in the Republic of Congo killed 114 people and up to 800 western lowland gorillas. This outbreak and all outbreaks between 2001-2003 began with human handling of infected animal carcasses. Ebola has since spread, putting the entire gorilla population at risk. An epidemiological model is presented to describe the combined effects of Ebola and hunting on persistence of gorillas. The number of infected gorillas also provides a means of assessing the risk of transmission to humans. Under current harvest practices and the estimated annual outbreak rate, the gorilla population is predicted to undergo a 97% decline within 100 years. Controlling bushmeat hunting may not be enough to prevent extinction if frequent outbreaks occur. 20/06/2007 Click here to read on... |

Patterns of gastrointestinal bacterial exchange between chimpanzees and humans involved in research and tourism in western Uganda
Ecological overlap may increase the risks of microbial exchange between humans and wild non-human primates. Escherichia coli bacteria were collected from chimpanzees and humans in Kibale National Park, western Uganda, in May and June 2004, in order to examine whether interaction between humans and apes in the wild might affect gastrointestinal bacterial communities in the two species. Chimpanzees harbored bacteria genetically more similar to those of humans employed in chimpanzee-directed research and tourism than to those of humans from a local village. Most humans (81.6%) and 4.4% of chimpanzees harbored at least one isolate resistant to locally available antibiotics. In isolates from both humans and chimpanzees, resistance was higher to five of these antibiotics than to Ceftiofur, an antibiotic not available in the region. These data indicate that humans and apes interacting in the wild can share genetically and phenotypically similar gastrointestinal bacteria, presumably originating from common environmental sources. Strategies to limit transmission of pathogens between humans and primates, whether that transmission is direct or indirect, would benefit both human health and primate conservation. 08/04/2007 Click here to read on... |

TGN1412: time to change the paradigm for the testing of new pharmaceuticals
Clinical studies in human volunteers are an essential part of drug development. These studies are designed to account for possible differences between the effects of pharmaceutical products in preclinical studies and in humans. However, the tragic outcome of the recent Phase 1 clinical trial on TGN1412 casts considerable doubt over the relevance of this traditional drug development paradigm to the testing of therapeutic agents for human use. The role of alternatives to animal testing is considered, and a series of recommendations are made, which could ensure that clinical trials are well informed and based on the most relevant scientific information. 01/05/2006 Click here to read on... |

Genetic Signature of Anthropogenic Population Collapse in Orang-utans
Great ape populations are undergoing a dramatic decline, which is predicted to result in their extinction in the wild from entire regions in the near future. Recent findings have particularly focused on African apes, and have implicated multiple factors contributing to this decline, such as deforestation, hunting, and disease. Less well-publicised, but equally dramatic, has been the decline in orang-utans, whose distribution is limited to parts of Sumatra and Borneo. Using the largest-ever genetic sample from wild orang-utan populations, we show strong evidence for a recent demographic collapse in North Eastern Borneo and demonstrate that this signature is independent of the mutation and demographic models used. This is the first demonstration that genetic data can detect and quantify the effect of recent, human-induced deforestation and habitat fragmentation on an endangered species. Because current demographic collapses are usually confounded by ancient events, this suggests a much more dramatic decline than demographic data alone and emphasises the need for major conservation efforts. 24/01/2006 Click here to read on... |

Selective logging in the Brazilian Amazon
Amazon deforestation has been measured by remote sensing for three decades. In comparison, selective logging has been mostly invisible to satellites. We developed a large-scale, high-resolution, automated remote-sensing analysis of selective logging in the top five timber-producing states of the Brazilian Amazon. Logged areas ranged from 12,075 to 19,823 square kilometers per year (T14%) between 1999 and 2002, equivalent to 60 to 123% of previously reported deforestation area. Up to 1200 square kilometers per year of logging were observed on conservation lands. Each year, 27 million to 50 million cubic meters of wood were extracted, and a gross flux of È0.1 billion metric tons of carbon was destined for release to the atmosphere by logging. 21/10/2005 Click here to read on... |

Use of nonhuman primates in entertainment in entertainment in Southeast Asia
The modern zoo has its origins in the royal menageries of ages past, where animals were kept for purposes of exhibition and entertainment for the privileged few. What demarcates modern zoos from the animal menageries? Zoos no longer treat animals as display items solely for public enjoyment. Besides the fundamental objective of providing entertainment to the public, modern zoos also play a part as educators and conservationists. Yet zoos face a constant stream of criticism. An important component of the zoo experience still involves animal shows and photography featuring a whole array of species. 01/04/2005 Click here to read on... |

Hainan Black-crested Gibbon is Headed For Extinction
Although Hainan black-crested gibbons have been on the list of the most endangered primate species in the world for many years, their environment is still deteriorating, especially on Hainan Island. Our findings indicate that the species is unlikely to survive the next decades unless efficient conservation policies and strategies are put in place immediately. Census data show that populations of the species used to occur across the whole island, but in 2003 only 13 individuals could be found, confined to a small region, the Bawangling Natural Reserve (19 021-19 081N and 109 021-109131 E), in the western part of the island, covering only 14-16 km2. In other words, ca. 99% of the habitat has vanished in the past 300 years. Such dramatic change has pushed the species to the edge of extinction; only 2 groups and 2 solitary adult males, remained in 2003. Two adult females, 2 juveniles and one infant comprise Group A, in Donger, the core area of the western part of the reserve; and 1 adult male, 2 adult females, 1 juvenile and 1 infant formed another group (B), confined to another core area (Nanchahe) in the northern part of the reserve. The dramatic decline in the gibbon population has occurred due to vegetation reduction, ecological deterioration and extensive human impact. The forest cover was reduced from 95.5% 2000 years ago to just 4% in 1999; and the human population in 2003 was 330% larger than in 1950. 01/04/2005 Click here to read on... |

Lowland forest loss in protected areas of Indonesian Borneo
The ecology of Bornean rainforests is driven by El Niño-induced droughts that trigger synchronous fruiting among trees and bursts of faunal reproduction that sustain vertebrate populations. However, many of these species- and carbon-rich ecosystems have been destroyed by logging and conversion, which increasingly threaten protected areas. Our satellite, Geographic Information System, and field-based analyses show that from 1985 to 2001, Kalimantan's protected lowland forests declined by more than 56% (>29,000 square kilometers). Even uninhabited frontier parks are logged to supply international markets. "Protected" forests have become increasingly isolated and deforested and their buffer zones degraded. Preserving the ecological integrity of Kalimantan's rainforests requires immediate transnational management. 13/02/2004 Click here to read on... |

Ethical and welfare implications of the acquisition and transport of non-human primates for use in research and testing
Assessment of the ethical and welfare implications of any laboratory animal use should encompass the entire life-history of the animals concerned, including their acquisition and transport. This is particularly important in the case of non-human primates, because the acquisition of some species involves capture from the wild, inadequate husbandry, and/or lengthy, multistaged travel from the country of origin to the laboratory where they are used. Thus, non-human primates endure considerable harms even before they reach the laboratory. Despite this, the information necessary to increase awareness of, and to assess, the potential harms of acquisition and transport is not readily available. This paper highlights the ethical and welfare concerns associated with these processes and makes recommendations intended to reduce their impact on welfare. The information presented is collated from a recent report that analyses the UK trade in non-human primates for research and testing, but many of the concerns and recommendations are applicable in an international forum. The need to minimise suffering is emphasised, as is the need for critical review of the necessity and justification for all non-human primate use, a reduction in the numbers used, and the development of alternatives to replace their use. 01/01/2004 Click here to read on... |

Catastrophic Ape Decline in Western Equatorial Africa
Because rapidly expanding human populations have devastated gorilla (Gorilla gorilla) and common chimpanzee (Pan troglodytes) habitats in East and West Africa, the relatively intact forests of western equatorial Africa have been viewed as the last stronghold of African apes. Gabon and the Republic of Congo alone are thought to hold roughly 80% of the world's gorillas and most of the common chimpanzees. Here we present survey results conservatively indicating that ape populations in Gabon declined by more than half between 1983 and 2000. The primary cause of the decline in ape numbers during this period was commercial hunting, facilitated by the rapid expansion of mechanized logging. Furthermore, Ebola haemorrhagic fever is currently spreading through ape populations in Gabon and Congo and now rivals hunting as a threat to apes. Gorillas and common chimpanzees should be elevated immediately to `critically endangered' status. Without aggressive investments in law enforcement, protected area management and Ebola prevention, the next decade will see our closest relatives pushed to the brink of extinction. 10/04/2003 Click here to read on... |

The Oil Industry as an underlying factor in the bushmeat crisis in Central Africa
Although deforestation and habitat loss are considered the main causes of wildlife depletion, the bushmeat trade is one of the foremost threats to biodiversity conservation in central Africa. In 1997 and 1998, we set up a bushmeat trade monitoring program in the town of Gamba to assess the pressure exerted on wildlife by the human population attracted by the oil industry in the Gamba Protected Areas Complex. During 279 days of observations, we recorded 19 mammal species, 4 bird species, and 7 reptile taxa, for a total of 2845 animal carcasses with an estimated weight of 189,728 kg. Even though the bushmeat trade is illegal in protected areas, calculation of annual production levels and hunting yields showed that this trade is not sustainable for some species. We calculated the ratio of bushmeat found in the markets of Gamba to the human population. Compared with other Gabonese towns, Gamba had the highest ratio in the country. We suggest that the oil industry is another contributor to the bushmeat crisis in central Africa. It is important to recognize the role of oil companies in the current crisis in order to heighten the awareness of the public and of oil companies and to seek ways of lessening the impact of the oil industry on the bushmeat trade in central Africa. 06/03/2003 Click here to read on... |

The status of the Sumatran orang-utan Pongo abelii: an update
The Sumatran orang-utan Pongo abelii is categorized as Critically Endangered on the 2002 IUCN Red List. Although several reports have suggested that the species occurs in the region to the south of Lake Toba in Sumatra, Indonesia, their distribution is poorly known. In order to determine whether orang-utans still occur in this region we surveyed areas in which orang-utans have been reported as well as a number of other forested areas. Orang-utan signs were found in only two areas. This indicates that habitat loss and hunting have recently caused local extinctions. We combine these results with other available information to provide a summary of the current distribution of P. abelii in Sumatra and, based on our surveys, previous population estimates, and estimates of losses, we speculate that only c. 3,500 orang-utans still occur in the wild in Sumatra at the end of 2002. 11/02/2003 Click here to read on... |

Behavioral Abnormalities in Captive Nonhuman Primates
In this study, we dealt with 11 species of nonhuman primates across 10 zoos in India. We recorded behavior as instantaneous scans between 9 a.m. and 5 p.m. In the study, we segregated behaviors for analyses into abnormal, undesirable, active, and resting. The 4 types of abnormal behavior exhibited included floating limb, self-biting, self-clasping, and stereotypic pacing. In the study, we recorded 2 types of undesirable behavior: autoerotic stimulation and begging. Langurs and group-housed macaques did not exhibit undesirable behaviors. A male lion-tailed macaque and a male gibbon exhibited begging behavior. autoerotic stimulation and self-biting occurred rarely. Males exhibited higher levels of undesirable behavior than did females. Animals confiscated from touring zoos, circuses, and animal traders exhibited higher levels of abnormal behaviors than did animals reared in larger, recognized zoos. The stump-tailed macaque was the only species to exhibit floating limb, autoerotic stimulation, self-biting, and self-clasping. Our results show that rearing experience and group composition influence the proportions of abnormal behavior exhibited by nonhuman primates in captivity. The history of early social and environmental deprivation in these species of captive nonhuman primates probably is critical in the development of behavioral pathologies. Establishing this will require further research. 01/01/2003 Click here to read on... |

Causal factors underlying the dramatic decline of the Sumatran orang-utan
The Sumatran orang-utan is in dramatic decline, including the population in its main stronghold, the Leuser Ecosystem, in Sumatra, Indonesia ( C. P. van Schaik et al. (2001)Oryx35, 14-25). The major threats to the survival of Sumatran orang-utans are identified as habitat loss (mainly from conversion to oil palm plantations), habitat degradation and habitat fragmentation. The immediate causes of this are identified as weak compliance with regulations and laws; weak law enforcement and the weak legal environment. Corruption is identified as the ultimate causal factor underlying these three immediate causal factors, along with a frontier mentality and bureaucratic constraints. Together, they have resulted in the destruction of prime orang-utan habitat. Several political actions are recommended to improve the effectiveness of habitat conservation for the orang-utan and several technical challenges are to be overcome once the policy context is right. The most crucial problem to solve is the lack of regular funds for enforcement operations and establishing a new system of enforcement that is effective. In addition, the Gunung Leuser National Park needs to be redesigned by enlarging it to cover all high biodiversity areas within the Leuser Ecosystem. Moreover, habitat corridors between important forest tracts need to be re-established. 20/12/2001 Click here to read on... |

The rehabilitation of captive baboons
Eleven baboons who had been singly housed indoors for an average of 5 years were moved to outdoor social groups in an attempt to provide a more species-typical environment and reduce high levels of abnormal behavior. Nine of the baboons were observed while in single housing and, over a 6-month period, while housed outdoors socially to document long-term changes in behavior. Abnormal behavior decreased significantly from an average of 14% of the observation time in the single cages to 3% in the sixth month of social housing. Cage manipulation and self-directed behaviors also significantly decreased, while social behavior, enrichment-directed behavior, and locomotion increased in social housing. Baboons that had been in long-term indoor single housing were able to reproduce and form stable social groups without injury. This study provides evidence that even behaviorally disturbed nonhuman primates can be successfully rehabilitated to live in social groups. 11/04/2001 Click here to read on... |

Extinction of a West African Red Colobus Monkey
We provide the first documented case of the extinction in the twentieth century of a widely recognized primate taxon. During surveys in Ghana and Côte d'Ivoire in 1993-1999, we were unable to find any surviving populations of Miss Waldron's red colobus monkey ( Procolobus badius waldroni), a primate taxon endemic to the forests of this part of West Africa. We conclude that this monkey, which at least one authority considers worthy of species status, is probably extinct. Hunting by humans appears to be the ultimate cause of the extinction. Until our surveys began, little attention had been paid to the plight of this red colobus monkey, despite its listing as endangered by the World Conservation Union. The extinction of other large animals in the Upper Guinea rainforest region is likely to follow soon unless more attention is paid to the full range of endangered forms and more resources are devoted to their rigorous protection. 05/01/2000 Click here to read on... |

Predicting the pattern of decline of African Primate Diversity: an extinction debt from historical deforestation
Populations that have survived extensive habitat loss may still face extinction owing to a time lag between initial habitat loss and eventual population collapse. Using island biogeography theory, I investigated the potential existence and magnitude of such "extinction debts" among African forest primates as a result of historical deforestation. Forest primate species exhibited a classic species-area relationship ( S = cA z) with forest habitat across African countries. I conducted three tests based on the species-area relationship that indicate extinction debts are likely to exist in African forest primates; in particular, several national extinctions should have already occurred solely as a result of forest loss in the last 50 years (if extinctions occurred simultaneously with habitat loss), but none of these extinctions have yet taken place. I also used the species-area relationship to predict the number of species that make up the total debt accumulated since deforestation began in these countries. My results suggest that in most countries the debt currently consists of over 30% of the forest primate fauna, which usually constitutes between four and eight species. These figures are likely to be accurate because the same model predicts with a reasonable degree of precision (1) the severity of threat of extinction from deforestation faced by country endemics, (2) the distribution of regional community endemics threatened by deforestation, and (3) the total number of African species threatened by deforestation (according to the 1996 IUCN Red List). My findings indicate that although protected areas are an essential part of conservation, the protection of the remaining forest alone may not be enough to prevent extinctions caused by habitat loss. 18/01/1999 Click here to read on... |
