Understanding the multi-scale effects of arable land landscape on epigaeic arthropod diversity is essential for biodiversity conservation and agroecosystem services. Our study explored overall effect elements at three scales landscape, habitat, field. We selected 11 areas to sample using trap method, construct models data. The results showed that: (1) On scale, 1500 m was optimal radius. Shanno...

Land cover and use changes are important to study for their impact on ecosystem services ultimately sustainability. In urban environments, a particularly research question addresses the relationship between urbanization-related biodiversity, subject controversies in literature. Birds an ecological group, useful answering this question. The present builds upon hypothesis according which avian di...

Many bird species depend on wetlands and the surrounding habitats. However, status of these wetlands, as well their biodiversity, is poorly understood maintained. From January to February 2021, we assessed compositions, relative abundances, distributions throughout five wetland habitats in East Gojjam zone. In each study site, systematic random sampling techniques were applied at a 4 km interva...

This poster presents the use of the Dublin Core for tools that make species distribution modeling. As a case study, this poster proposes the use of the Dublin Core for there to be a connection between the models generated by tools of species distribution, contributing to the area for biodiversity informatics.

Independently owned nature reserves are proliferating across the developing world. Nevertheless, the conservation community knows practically nothing about them. This paper examines the economic, ecological, and social impacts of ecotourism, as evidenced at thirty-two of these reserves. Ecotourism is shown to be the primary means through which reserves survive financially. This reliance provide...

The economic importance and uses of the large number of plant species of India make it essential for their biodiversity to be conserved. In order to undertake the steps for biodiversity conservation such as identiication of species and monitoring of climatic conditions, it is essential to eeciently manage the vast amount of biodiversity related data. This data includes taxonomic data, geographi...

Tropical landscape connectivity and matrix quality near large stands of primary forest are important factors that dictate biodiversity trends in communities. Suitable management surrounding may help conserve biodiversity, but areas with poor need attention to determine their long-term viability support native levels biodiversity. We examined variations species functional diversity community com...

(includes addition of the effect of " ditch lights ") Abstract The number of collisions and fatalities at rail-highway intersections has declined significantly over the past thirty years, despite considerable increases in the volume of both rail and highway traffic. This paper disaggregates the improvement into its constituent causes. Negative binomial regressions are conducted on a pooled data...
