Reduction of toxic hexavalent was studied by using four resistant strains of E. coli ASU 3, 7, 8 and 18 isolated from wastewater of EL-Malah canal located in Assuit city, Egypt. They showed relatively high minimal inhibitory concentrations (MIC) and found to be plasmid mediated with 65 and 27 Kb. E. coli ASU 7 represents the best with high resistance and reducing power of Cr (VI), so it may be ...

Species distribution models (SDMs) algorithms are powerful tools for predicting species distributions across the landscape under hypothesis that environmental conditions influence species' geography (Elith & Leathwick, 2009). In last decades, SDMs have been widely applied to assess effect of climate change on and impact invasive species, select suitable sites reintroductions, or address conserv...

The conservation of biodiversity is fraught with complexity and uncertainty (Hemming et al., 2022). To deliver on objectives, decision makers must navigate challenging social technical contexts while contending escalating threats (Maxwell 2016). Quantitative models are frequently used to help guide the making process, providing insight into complex scenarios by way attempting remove unstructure...

The availability of data related to species occurrences has favoured the development distribution models using only observations presence. These are intrinsically biased by sampling effort. Presence-only (PO) (SDM) typically account for this effect introducing additional considered be with sampling. This approach, however, does not allow characterisation effort and hinders interpretation model....

The combination of phylogenetic and spatial data, or phylogeography, can be used to assess how species have evolved in space time (Avise 2000). Phylogeography is considered a part historical biogeography, which aims explain the geographic distribution organisms according their evolutionary history (Sanmartín 2012). Although different approaches been infer biogeography species, these distinct li...

Ceratitis capitata (Wiedemann), the Mediterranean fruit fly or medfly, is one of world's most serious threats to fresh fruits. It highly polyphagous (recorded from over 300 hosts) and capable adapting a wide range climates. This pest has spread EPPO region mainly present in southern part, damaging Citrus Prunus. In Northern Central Europe records refer interceptions short-lived adventive popula...

Biodiversity is currently undergoing a human-induced extinction crisis comparable to previous mass extinctions (Ceballos et al., 2015; Dirzo 2014; Pievani, 2014). Among the main drivers of loss, climate change has already impacted biodiversity from individual genotypes whole ecosystems (IPBES, 2019; Scheffers 2016). This resulted in species extinctions, local extirpations and changes distributi...

The Sierra Nevada red fox Vulpes vulpes necator is listed as a threatened species under the California Endangered Species Act. It originally occurred throughout California’s Cascade and Sierra Nevada mountain regions. Its current distribution is unknown but should be determined in order to guide management actions. We used occurrence data from the only known population, in the Lassen Peak regio...
