Management of wildlife species has recently become a global concern as most are threatened to near extinction or endangered. The establishment of national parks such as the Sapo National Park (SNP) in the 1980s as a conservation area has been found as one of many solutions for protection of wildlife species in Liberia. Nonetheless, due to various natural and anthropogenic drivers and pressures, the SNP is under consistent threat of losing its biodiversity integrity. Various factors including wea...

Diclofenac (DCF) is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain in joint-related diseases. It is not completely metabolized after consumption and cannot be easily removed using conventional wastewater treatment. DCF has been detected in water bodies and may pose chronic effects on the endocrines of living organisms even at low-level exposure. Heterogeneous photocatalysis provides an alternative and efficient method of degrading DCF. In this study, the photocatalytic remov...

Wild populations of stingless bees in Costa Rica present a valuable information gap in terms of wild ecology, due to the great difficulty that national parks and biological reserves represent to carry out population studies due to their great exemption. Due to this, the meliponarium and rescue projects of these bees provide an important opportunity for their study since they bring together local wild populations in the same physical space. In Costa Rica, there are several types of Wildlife Manag...

This research aims to highlight the effect of human activities and speculative fishing on the dynamic of Tiko mangrove landscapes. The study is based on the collection of bibliographical and factual data (field observations, botanical records) and the diachronic analysis of satellite images of the locality over the past five decades. The NDVI method was used to illustrate the dynamics of land use between 1976, 1986, 1996, 2006 and 2016. Botanical surveys were carried out in three transects 100 m...

For several decades, many households in rural areas have relied on surrounding forests for their livelihoods, safety nets and sustenance. This reliance is most often determined by the household’s characteristics, available forests and economic benefits. That notwithstanding, the demand for more farmlands and unsustainable harvesting of forest resources are pushing these forests into depletion. This rapid decline endangers the livelihoods of forest-reliant households, threatens biodiversity and i...

In Uganda, sorghum constitutes the second most widely grown cereal according to the latest statistics from the country’s statistics body, the Uganda Bureau of Statistics. This notwithstanding, there has been, in the context of Uganda, very little research and published literature on its potential to sequester carbon. There is no sufficient data on the exact levels of carbon sequestered by this sorghum/legume intercropping system, which is widespread as a technology within Uganda’s smallholder so...

In order to study the ecological adaptability of brewing functional Indica rice varieties in the ecological area of southern Sichuan, six Indica hybrid rice varieties were used as experimental materials to analyze the differences in the rice growth period, yield and yield components, grain filling characteristics, starch and soluble sugar accumulation dynamics under the ecological conditions of southern Sichuan. The results showed that there were significant differences in yield fo...

In this study, 60 direct seeding rice varieties with different genotypes were used as experimental materials. Through long-term submergence treatment (7 d and 14 d), the responses of different genotypes to submergence stress were compared in germination and seedling emergence, stem, leaf and root elongation, starch and other storage material consumption. The results showed that there were significant differences in submergence tolerance of different genotypes at the germination and seedling stag...

This paper examines forest conservation dynamics and the ensuing challenges encountered in Cameroon. It assesses forest resources and identifies forest conservation patterns and the various challenges faced by these initiatives. To attain this objective, a broad review of published literature was performed using Semantic Scholar, Google Scholar, Research gate and Web of Science. The study observed that, despite various management practices, enormous challenges still exist which give rise to fore...

The problem of extracting surface crack information in mining area is studied. The unmanned aerial vehicle (UAV) image is used as the data source for multi-scale segmentation. The rule set is constructed based on the spectral and shape features of surface cracks. The object-oriented extraction of crack information is carried out by using the principle of fuzzy classification, and the surface crack information in mining area is successfully extracted. The extraction accuracy of surface cracks is ...
