Biodiversity is fast declining, especially in African countries like Nigeria, with the lack of data. This study was conducted to quantify biodiversity studies in Nigeria available on the Web of Science database. Data were collected from the Web of Science core collection from 1970-2020 with “Biodiversity” as the search term. Of the 141 781 global research on biodiversity, 155 (0.1%) were conducted in Nigeria. Ecology and Environmental Science Journal were the top leading Web of Science subject category, both with 34 published articles, followed by Biodiversity Conservation (21) and Plant Science (19). Bergi et al. (2007) is the most cited article with forty-nine (49) citations. The University of Ibadan and Luiselli L. were the affiliated authors with the highest number of published articles on biodiversity in Nigeria. Overall, there is an increasing trend of biodiversity research in Nigeria over the years. However, in comparison to the global research in biodiversity and considering the rate of biodiversity loss both locally and globally, there is a need for more biodiversity research in Nigeria. Wildlife managers and conservationists should pay more attention to biodiversity research in Nigeria.

Like most other species, the Asiatic black bear is vulnerable to a wide range of diseases, including infection, inflammation, parasitic infestation, and degenerative disease. The study reported the surgical and conservative management of maggot wounds, including anesthetic protocol and postoperative care in Himalayan Black Bear (Ursus thibetanus). Anesthesia was performed successfully by administering Xylazine and Ketamineintramuscularly (IM) by remote injection using a tranquilizing gun with a 10CC anesthetic dart. The animals' clinical evaluation showed an induction time of 4.5 minutes, duration of anesthesia was 72.0 minutes, and recovery time of 38.0 minutes. All the physiological parameters were within normal limits.

The abundance and diversity of bird species were studied in Ehor Forest Reserve Edo state, Nigeria. The study area was divided into three compartments based on their different land-use types. The line transects method was used to collect bird species diversity and abundance in the study area. In all of 60 transect lines were randomly placed, measuring 1000 m. Each transect was divided into 200 m sections, with each block having 20 transects randomly placed. The site size determined the number of transect lines. Data were collected for six months (Dry and Wet seasons) in 20018. The quadrant method was used to determine plant species composition. This method involves a total enumeration count (TEC) of all trees above 1m in height and a Basal area of not less than 10cm from 25×25m 2 quadrant sample plot, which was randomly selected through balloting from each sampling compartments. Thirty-five (31) bird species were recorded in the Farmland, Forty-five (45) bird species in the Fallow Area, and sixty-seven (67) species encountered in the Undisturbed forest area. In all, a total of 143 bird species belonging to 43 families and 18 orders were recorded in the three study sites; the Order Passeriformes had the highest frequency (51 %) of the total number of birds recorded, while the dominant families were Cuculidae and Pycnonotidae, comprising (7.4 %) of the total species One endangered bird species, African Grey Parrot and 13 species cuculidae were encountered in the study area. A total of 117 tree species were enumerated in the study area, Ficus exasperata had the highest DBH, while Ceiba pentandra has the highest mean height. Alchornea oppositifolia has the highest frequency of occurrence in the study area. 2 quadrant sample plot which was randomly selected through balloting form each sampling compartments.

Spatial evaluation of the physicochemical parameters of River Benue in relation to the habitat requirements of west African Manatee was conducted. The River was divided into four segments; Makurdi, Abinsi, Gbajimba, and Gbaji. In each segment, ten (10) sample points were randomly selected and the following parameters; Temperature, Dissolved Oxygen (DO), pH, Total dissolved solids, (TDS), Electrical conductivity (EC), and Biological oxygen demand (BOD) were measured. Data collected were subjected to statistical analysis. The result indicated that there were significant differences in the pH, Electrical conductivity, and Biological oxygen demand (BOD) among the four study areas. The result also indicated significant differences between the rainy season and dry season conditions of the water body. The result indicated that Manatees were highly adaptable to the physicochemical differences between the rainy season and the dry season.

Numerous published research in habitat suitability of various flora and fauna species show that habitat conservation is the most important component of biodiversity conservation. Among wildlife species, some are more important due to the declining population and known ecological importance. In fact, these species can be used as an indicator to consider new places or modify conservation areas' boundaries. The complexity of allocating land for conservation increases when species become more dependent on artificial and semi-artificial lands, due to the destruction of natural habitats. The present study was conducted to investigate the suitability habitat of Asian houbara bustard as a rare species that faced a sharp decline in population in recent decades in part of its wintering habitat in Sistan. The method for assessing habitat suitability was Maxent. The results showed that the most important environmental variables were the distance from human settlements and agricultural lands. This species has a strong tendency to human-made areas. Although part of its suitable habitat overlaps with protected areas, conservation of this species has not been adequate so far, and a sharp decline was seen in its population in recent years. The results of this study emphasize the need to take management measures to reduce the conflict of interest between humans and this bird and increase public participation in the conservation of this species.

Scincopus fasciatus (Peters, 1864) is a nocturnal skink species rarely recorded from its large global distribution area. In Tunisia, it was reported for the first time at the end of the 19th century. After different field surveys in southern Tunisia, I found the species active many times in Bou Hedma national park. Additional new records concern road-killed animals. In this paper, a review was made on the species distribution in Tunisia, and its habitats are described.

Identifying various geomorphologic units with ecotourism attraction and determining the high-quality landscape are important steps in order to improve the quality and protecting natural ecosystems. The present study aims to achieve a more appropriate landscape pattern in the framework of ecotourism development in the geo-tourism region of Bishe Waterfall, in Iran taking into account the landscape quality assessment and landscape ecological indicators. Appropriate ways are proposed to develop ecotourism for achieving sustainable ecotourism. For data analysis, Arc GIS, Idrisi and Fragstats software were used. Also, The area of the study was determined using google earth software, and LAND SAT and NDVI images were used to produce vegetation type and density maps. The landscape quality units were evaluated by the development of landforms, and then 18 areas were selected as scenic landscapes and verified by using questionnaires. To evaluate the visual aspect, the area was divided into 17 49-hectare cells, and the corresponding metrics were compiled in Fragstats and the corresponding maps were produced for analyzing and evaluating the landscape pattern using Arc GIS. The results showed three levels of landscape quality assessment, which is distinct, ordinary and, poor, where the landscape quality from the horizontal perspective corresponds to the landscape quality from the vertical perspective, but the results of the visual assessment of the area with the landform model showed that there is a conflict between the aesthetics and ecology in the region.
