The Goliath beetle (Goliathus goliatus) is one of the largest and most commercially valuable (for collection exports) beetle species worldwide, and occurs in West and Central Africa, with polymorphic populations being found in Benin, Eastern Nigeria, and Western Cameroun. The white morph is the most commercially valuable, and therefore is actively searched for by hunters and dealers. In a long-term, opportunistically conducted study in south-eastern Nigeria, we documented a substantial decline of the white morph compared to the normally coloured brown morph, although an overall decline in the number of observed beetles was evident for both colour morphs. Although a combination of reasons may have caused the white form decline, it is likely that overcollecting was the primary threat behind the observed pattern. Therefore, we urge the competent authorities to better protect the polymorphic populations of these giant beetles and the International Union for the Conservation of Nature (IUCN) to make a quick assessment for eventual inclusion of the species among the threatened taxa Red List.

Despite increasing pressures on freshwater resources worldwide, and the threatened status of most freshwater turtles, there is still limited knowledge of habitat use and niche partitioning in Afrotropical freshwater turtle communities. In this study, we describe habitat associations, community diversity, and temporal patterns of occurrence of freshwater turtle species in the Dahomey Gap ecoregion of Ghana (West Africa). We gathered data from 13 sites in central Ghana and along the Sene Arm of Lake Volta in the Digya National Park (Bono East Region). We employed opportunistic short-term surveys (at seven sites) together with longer-term (six-months duration) standardized evaluations of turtle presence and numbers in different habitats (at six sites). Overall, a total of 210 turtle individuals of four species (Trionyx triunguis, Cyclanorbis senegalensis, Pelomedusa sp. and Pelusios castaneus) were recorded; precise capture sites and habitat type were recorded for 139 individuals, but the 71 individuals observed in marketplaces were not considered in our analyses. At a local scale, we observed three sympatric species in various study sites. In each of these sites, the dominant species was either C. senegalensis or Pelomedusa sp., with the latter species being more abundant in temporary waterbodies and C. senegalensis more numerous in permanent ones. A Multiple Correspondence Analysis suggested that, in permanent waterbodies all species were associated with similar physical habitat variables. In a Canonical Correspondence Analysis, we showed that the density of herbaceous emergent vegetation was more important for P. castaneus than for C. senegalensis. Comparisons of diversity metrics between our study sites and previous studies revealed that turtle community composition was similar across savannah sites.

Pelusios (Testudines: Pleurodira) is an Afrotropical endemic genus of freshwater turtles that have adapted to a variety of habitats, with savannahs and forests being their two main habitat types. Although considered generally carnivorous, these turtles have rarely been subjected to detailed field surveys for determining their quantitative diet. In this paper, by using both the literature and original data, we analyze the diet of several Pelusios populations: three P. adansonii populations from South Sudan, one P. nanus from Zambia, seven P. castaneus from Nigeria, Benin and Togo, and four P. niger from Nigeria. All species were omnivorous but with a clear preponderance of the prey items being of animal origin (e.g., amphibians, fish, arthropods and annelids). Saturation curves revealed that the diet composition of all the surveyed populations was adequately assessed, and the diversity profiles indicated that all the populations were relatively similar in terms of overall dietary diversity. General Linear Models (GLM) showed a negative effect of vegetation cover on Anura adult consumption by turtles, and showed that the frequencies of Anura tadpoles, fish, reptiles and birds on Pelusios diets increased with the increase in vegetation cover. The GLM model also showed positive effects of individual body size on algae, Bivalvia, reptiles, birds and small mammal consumption by turtles, and underlined that the predation on Arachnida decreased with the increase in turtle body size. In all species, there were no significant intersexual dietary differences, whereas there were substantial ontogenetic dietary changes in three out of four species. Small-sized individuals of P. castaneus, P. niger and P. adansonii tended to feed mainly upon insects, with the adults also taking many fish and adult frogs, and in the case of P. niger, also birds and small mammals. Conversely, in P. nanus, the diet composition did not vary substantially from the juvenile to the adult age. All species appeared substantially generalist in terms of their diet composition, although the effects of season (wet versus dry) were not adequately assessed by our study.

Ebola virus disease, EVD, has been linked with wild meat. In Nigeria, strict restrictions on wild meat sales were applied after the first case in July 2014. We quantified wild meat trade in nine markets in southern Nigeria, during Oct. 2010 – Dec. 2019, and undertook consumer interviews during 2018–2019. Wild meat sales fell to low levels between during EVD (Jul. - Oct. 2014), after which Nigeria was declared Ebola-free. Prior to EVD (2012–2014), reptile carcass numbers declined markedly, collapsed during EVD, but rebounded immediately post-EVD until 2017 to values exceeding pre-EVD (especially true for turtles and tortoises). Reptile consumption increased as mammal numbers declined. After 2017, reptile numbers fell and remained low until the end of the study, indicating population collapses and depletion. Fruit bats and primates did not recover after EVD, but ungulates, rodents and carnivores increased significantly after EVD though never reached pre-EVD levels. Interviews revealed strong rural versus urban and age-specific differences regarding wild meat consumption and attitudes. Most people worried about Ebola and more than half of interviewees agreed that wild meat poses a transmission risk. Except urban males, over-60-year olds were least informed about the Ebola risk of wild meat, indicating that any future behavioural change campaign should focus on the younger age classes. Unlike other studies, our research clearly shows that changes in purchasing behaviour of consumers and education campaigns were effective in reducing the trade of bats and primates, animal groups likely to be implicated in the transmission of Ebola.

Habitat modification is a major factor in the decline of reptile populations. The degree of the decline has been shown to be directly related to the intensity of habitat modification. Farming practices and urbanization are just two of the factors involved indicating that the development of practices that minimize or cancel anthropogenic impacts is urgently needed to prevent further declines. This requires knowledge of population ecology of reptiles in both disturbed and pristine habitats. In this paper, we describe aspects of green lizard (Lacerta bilineata) population ecology in a forest–pasture relatively pristine mosaic habitat in central Italy and a fragmented habitat in western France. In Italy, habitat niche overlap was very high between males and females but very low between males and juveniles. For male and female abundances, general linear models showed that the adult abundances increased with the increase of Rubus bushes, whereas juvenile abundance increased with the increase of Spartium bushes. Contingency table analysis showed that juveniles were also much more frequently observed in grasslands than adults of either sexes. The observed ontogenetic structural niche pattern was likely due to intraspecific competition avoidance, competition interference, and cannibalism. The persistence of the same patterns across years demonstrates a temporal stability of the ontogenetic structural niche pattern. Over the length of the study period, population densities were stable in the Italian population, but densities were much higher by around five times in the hedgerow in the fragmented habitat in France. In the hedgerow, monthly lizard presence was uneven, with the greatest number of sightings in June and July. Overall, our study provided no support for the notion that lizard abundance/density should be lower in modified compared to unmodified habitats, and clearly revealed that a careful management of the hedgerows is crucial for the conservation of this lizard species in agro-forest ecosystems.

Resource partitioning, the division of limited resources by species to help avoid competition, has been observed in freshwater turtle assemblages in several natural systems but has rarely been studied in tropical African ecosystems. Here, we investigate habitat preferences of two congeneric species in the family Pelomedusidae, Pelusios castaneus and P. cupulatta, in riverine/wetland habitats in the southern Ivory Coast (West Africa). Pelusios castaneus is a widespread species across West-central African savannahs and open forests, whereas P. cupulatta is endemic to the Upper Guinean forest region in West Africa. The two species have a similar diet composition (mainly carnivorous) but diverge considerably in body size, P. cupulatta being much larger. We use hand-fishing-nets and fishing funnel traps to record turtles in 18 distinct sites and analyze habitat preferences by species at two spatial scales. At a macro-habitat scale, P. castaneus is captured mainly in marshlands, whereas P. cupulatta is found in both rivers and wetlands. The two species differ significantly in their use of: (i) banks (P. castaneus being found primarily in spots with grassy banks, whereas P. cupulatta is found in spots with forested banks), and (ii) aquatic vegetation (P. cupulatta prefers spots with more abundant aquatic vegetation than P. castaneus), but both species select sites with no or moderate current. Additionally, in sites where P. cupulatta is not found, P. castaneus expands its spatial niche at multiple habitat scales, notably invading waterbodies with forested banks. Our results suggest that these two Pelomedusid turtle species potentially compete in the freshwater habitats in the southern Ivory Coast.

The Nubian flapshell turtle, Cyclanorbis elegans, is one of the rarest turtle species in the world and has even been considered as possibly extinct because no free-ranging individuals have been recorded in recent years. Here, we report on 2 large adults (> 60 cm total carapace length) of this species captured along the White Nile River course between the towns of Juba and Mongalla in South Sudan; these specimens were found in very large stretches of the riverbed, with the presence of seasonal and permanent wetlands (ponds and swamps) in the surroundings and with abundant bank vegetation. These turtles are hunted and eaten by local communities for subsistence and traditional medicine and are under serious threat due to overfishing and habitat loss.

All animals subject to legal and illegal trade are to be considered from an economical point of view as real economic goods. This preliminary study shows how the economic correlates of the wild trade may influence the elasticity of the demand curve. The elasticity of the demand curve should become a driver in the conservation policy focused to protect the biodiversity of the species. The prices trends are an important key to fully study the elasticity of demand. Understanding the response of consumers and hunters to perceived rarity is vital for predicting the impact of intervention strategies that seek to minimize extinction risk (Hall 2008). The trade in animals is directed towards markets with a higher level of income. In the global market, as the goods increase in price, they will always find their demand. For conservation reasons it is extremely important to understand which are, for each species, the reactions of the demand curve respect to the price changes

Understanding age-dependent mortality processes is a critical challenge for population biologists. Actuarial senescence appears to be a common process across the tree of life. Senescence patterns are highly variable in pluricellular organisms: senescence can be gradual or sharp and its onset may be early or delayed. By contrast, studies revealed that organisms may also not experience senescence at all while others display a “negative senescence”; i.e. a decrease of mortality rate with age. To date, studies on senescence have largely focused on human and other endotherm vertebrates, limiting our understanding of senescence in amniotes as a whole. By contrast, few have examined the diversity of senescence patterns in ectotherm vertebrates as reptiles. Here, we examined population dynamics and age-dependent mortality patterns in three tropical tortoises (Kinixys erosa, Kinixys homeana, Kinixys nogueyi) and snakes (Bitis gabonica, Bitis nasicornis, Causus maculatus). Our study revealed that tortoises ofKinixysgenus had a higher survival and a lower recruitment than snakes of the generaBitisandCausus, indicating that they have a slower life history. Furthermore, we showed that survival more slowly decreased with age in tortoises than in snakes. In addition, we highlighted contrasted patterns of age-dependent mortality in the three genera. InKinixys, the relationship between mortality rate and age was positive and linear, suggesting gradual senescence over tortoise lifetime. By contrast, the relationship between mortality rate and age was negative and sharp inBitisandCausus, possibly due to a “negative senescence” starting early in life. Our study highlighted various age-dependent mortality patterns in tropical reptiles. It also contributed to extend our knowledge of senescence in ectotherm vertebrates whose the demography is still poorly understood. In addition, while negative senescence has never been reported in endotherm vertebrates, our results showed that it can be common phenomenon in ectotherms.

The ecology and activity patterns of many tropical vertebrate species are heavily influenced by the seasonal alternance of dry and wet periods. However, the effects of the dry–wet seasonal alternance on feeding habits of tropical vertebrates are poorly known. In this paper, the monthly variations in the diet of the scincid lizard Trachylepis quinquetaeniata were studied, by faecal pellet analysis, in a sandy beach area of southern Togo (West Africa) in relation to both rainfall and temperature‐related variables. The diet was basically insectivorous, with five prey types (Coleoptera adults and larvae, Lepidoptera adults and larvae and Formicidae) being dominant in the pellets. Prey composition was similar between sexes, but varied considerably across months. There was a positive correlation between mean monthly rainfall and number of prey categories eaten in each month. General linear models (GLM) showed that both Simpson and Shannon indices increased with the monthly number of rainy days. GLM also showed that rainfall regime influenced the frequency of eaten Coleoptera adults and larvae and of Lepidoptera adults and larvae, with no effect on Formicoidea. Our study confirms that dietary patterns of tropical lizards are influenced by the wet‐dry‐seasonal alternance, and that both the taxonomic composition of the diet and the dietary diversity metrics are significantly affected. We also demonstrated that rainfall is more important than temperature in determining the dietary variations, and that, among the rainfall‐linked variables, it is the monthly number of rainy days that represents the most important variable.

There is an unprecedented demand for bushmeat in large cities in sub-Saharan Africa, and this is a major threat to many species. We conducted 2,040 interviews in six cities in four West African countries, in forest and savannah settings. We analysed age- and sex-related differences in the frequency of bushmeat consumption. Overall, we found similar patterns in all cities: 62.2% of men and 72.1% of women said they would never eat bushmeat, whereas 12.8% of men and 8.8% of women said they liked bushmeat and ate it regularly. Younger generations of both sexes tended not to eat bushmeat, regardless of their city of origin. This study of the effects of age, gender and geographical location on bushmeat consumption in African cities provides insights regarding which population groups to target in campaigns to change behaviours.

This paper presents a model of the Ecological Economy as instrument of management lands. The model relates the human capital with natural capital and pursuing the environmental sustainability in primary emphasis in the economic system. The protection of biodiversity must be part of a long-term development strategy. A profit becomes sustainable when its increase or its stability is not negatively affecting the natural capital over time. The identification of the equilibrium point in a set of lands permits the pinpoint of a baskets of goods and services that it maintains the biodiversity level in a target area. The basket identified is the key tool to address the management policy in the target areas. These policies will promote economic sustainable growth with more income for the families of the local communities in the park area for a selected target of lands. Thus, the decision process in the land management will be the result of a scientific identification process.
