The adoption of the Aichi Biodiversity Targets (ABTs) was supposed to increase conservation awareness in different countries and regions of the world. However, there seems to be a limited understanding of the importance of ecosystem services, offered by biological diversity. Thus, the continued decline in biodiversity, especially in developing countries. This study appraised the level of success of the first target of Nigeria's National Biodiversity Strategy and Action Plan (NBSAP), which is hinged on the first ABT. In a national survey, data were obtained from a total of 1,124 respondents (839 professionals and 285 non-professionals), using a structured questionnaire. Information on the respondents' knowledge of biodiversity conservation and the associated ecosystem services, were elicited. Most of the non-professionals had a low level of understanding of biodiversity concepts (4.9 ± 1.7 to 20.5 ± 3.4%), while there was a moderate level of understanding among the professionals (48.0 ± 8.6 to 88.8 ± 3.4%). Awareness of the NBSAP was low for both groups (43.8 ± 7.2% professionals and 12.1 ± 3.7% non-professionals). The study concludes that there is a need to step up campaigns on biodiversity conservation in Nigeria and promote visits to natural sites. Youth engagement through the employment of graduates of biology-related disciplines, to educate the public on biodiversity conservation and the action plan, could also be a strong determinant to the success of the NBSAP targets.
Diseases of wildlife origin have great impact on the conservation of the vast global biodiversity and also take a toll on domestic animals’ and human health. Diseases of wildlife have the capacity to be of utmost concern because they can affect the economy and public health if not attended to promptly. An amazing 60% of emerging infectious diseases are zoonotic and many of the recent cases have been proved to originate from wildlife. Knowledge of genetics is important to curtail the emergence of overwhelming wildlife diseases. Understanding the genetics of these diseases is important to give a better understanding of how they can be prevented and controlled to forestall the decimation of wildlife populations and consequent effect on biodiversity. Being armed with the knowledge of both, host and pathogen or parasite genome, would go a long way to pursue the solutions to wildlife diseases and their transmission. This review is geared towards promoting the incorporation of genetics and genomics and its diverse concepts and techniques into the process of detection, characterization, control and prevention of wildlife diseases.
The epididymis plays an important role in sperm maturation, storage, transport and in the secretion of enzymes and proteins into the tubular lumen. In this study, we examined the histology, microstereology and immunohistochemical localization of alpha smooth muscle (αSMA) in the three regions of the epididymis of the African four-toed hedgehog (Atelerix albiventris). Ten adult males were captured from the wild in Ibadan, Nigeria, between May and October, 2016. The animals were euthanized and the epididymis (caput, corpus and cauda regions) were retrieved and fixed in buffered neutral formalin ahead of the paraffin technique, following standard procedures. The duct of the epididymis was lined by pseudostratified columnar epithelium comprising basal, principal and apical cells as well as intraepithelial lymphocytes in proximity to basal cells. The principal cells, the major cells encountered within the epididymal epithelium of the animal, decreased in population from the caput to the cauda epididymidis while the apical cells were more abundant in the cauda epididymidis. Positive reactions to αSMA were observed in the peritubular muscular coat of the epididymal duct as well as blood vessels across the three regions of the epididymis with the caput and cauda epididymidis showing stronger positive reactions compared to the corpus epididymidis. This study demonstrated that the histology, microstereology as well as the cellular constituents of the epididymal duct of the Atelerix albiventris are similar to those of other mammals with a slight variation. It has also highlighted variation in the localization of αSMA across the regions of the epididymis of the animal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
