and are the main vectors of the invasive bacteria and key threats to European plant health. Previous studies of the potential distribution of reveal that climatic factors are the main drivers of its distribution on the Mediterranean Basin scale. Other local studies reveal that the landscape could also have a role in the distribution of both species of and . Our work is aimed at understanding the role and importance of bioclimatic and landscape environmental factors in the distributions of the vector and potential vector species , , and on a regional scale across the Autonomous Community of Murcia (SE Spain), a region with relevant environmental gradients of thermality and crop intensity. We used sweeping nets for sampling 100 points during eight months in 2020. Using bioclimatic landscape composition and topographical variables, we carried out habitat suitability models for each species using the maximum entropy algorithm (MaxEnt). Distribution results for , and indicate a gradient in habitat suitability, with the optimum in the coldest and wettest areas in landscapes with a high proportion of forest. All three species are absent from the southern third of the study region, the hottest, driest and most intensively cultivated area. These results are useful and should be considered in contingency plans against possible invasions of in Mediterranean regions.

An Estimate of Wolverine Density for the Canadian Province of Alberta.
Ecol Evol
January 2025
Government of Alberta, Forestry and Parks Canmore Alberta Canada.
Article Synopsis
- Wolverines have faced significant range reduction globally, with complete extirpation from eastern Canada and some western prairie regions.
- In Alberta, where they are designated for conservation, researchers aimed to estimate wolverine abundance using existing density data and habitat relationships.
- Results indicated approximately 955 wolverines in the province, with only 544 classified as adults, suggesting a need for a reassessment of their conservation status and related protective measures.
The competing controls of glaciers, precipitation, and vegetation on high-mountain fluvial sediment yields.
Sci Adv
November 2024
School of Geographical and Earth Sciences, University of Glasgow, G12 8QQ, Scotland, UK.
Investigating erosion and river sediment yield in high-mountain areas is crucial for understanding landscape and biogeochemical responses to environmental change. We compile data on contemporary fluvial suspended sediment yield (SSY) and 12 environmental proxies from 151 rivers in High Mountain Asia surrounding the Tibetan Plateau. We demonstrate that glaciers exert a first-order control on fluvial SSYs, with high precipitation nonlinearly amplifying their role, especially in high-glacier cover basins.

This study investigates the biogeography of the Australian Camphorosmeae (Amaranthaceae ) lineage and how it relates to shifts in climatic niche and habitat types. Building on previous research and data resources, we integrate molecular phylogenetics, bioclimatic data and biogeographical models to deepen our understanding of the diversification and adaptation of this group across Australia's diverse landscapes in relation to palaeoclimatic changes. For 159 species representing 12 genera, georeferenced distribution points were used to define the most informative bioclimatic variables using principal component analysis.

- Species distribution modeling (SDM) is crucial for predicting where species can be found based on their presence/absence and environmental factors, focusing on current and future climate change impacts through 2050 and 2070.
- Data was collected from diverse sources for species occurrence, resulting in 105 locations, and 19 bioclimatic variables along with elevation data were used for modeling the distribution in the Western Ghats of India and Sri Lanka.
- Both models effectively highlighted significant habitat loss under future climate scenarios, emphasizing the urgent need for conservation efforts for critically endangered species in the region.
Regional variation in the landscape ecology of West Nile virus sentinel chicken seroconversion in Florida.
PLoS One
October 2024
Florida Medical Entomology Laboratory, Institute of Food and Agricultural Sciences, University of Florida, Gainesville, Florida, United States of America.
How landscape composition and configuration impact the distribution of multi-vector and multi-host mosquito vector-borne disease systems, such as West Nile virus (WNV), remains challenging because of complex habitat and resource requirements by hosts and vectors that affect transmission opportunities. We examined correlations between landscape composition and configuration and 2018 WNV sentinel chicken seroconversion in Florida, USA across the state and within five National Oceanic Atmospheric Administration (NOAA) bioclimatic regions to understand strength and variation of landscape effects during an elevated transmission year. Although few landscape studies have examined WNV in Florida, we expected higher percentages of residential or medium-developed landscapes and more fragmented landscapes would be positively correlated with WNV seroconversion owing to the main mosquito vector habitats and avian host distributions.
