Abstract Japanese encephalitis virus (JEV), a zoonotic, mosquito-borne virus, has broad circulation across the Central Indo-Pacific biogeographical region (CIPBR), which recently expanded dramatically within this southeastern Australia over summer of 2021-2022. Preliminary investigation landscape epidemiology outbreaks JEV in Australian piggeries found associations with particular structure as well ardeid species richness. The ways waterbird from diverse taxonomic pools substantial functional variation might couple JEV-associated was not explored, and therefore, key questions regarding infection ecology remain unanswered. Moreover, given established presence CIBPR, extent to landscapes reflect broader regional patterns biogeography presents further knowledge gap particularly respect potential dispersal via maintenance hosts. current study investigated presence, ecological traits, diversity distribution at scale, how these aligned confirmed detections eastern wider CIPBR. results showed that habitat associated detection 2022 more widely CIPBR last 20 years reflects range representing 8 families 4 orders (ardeids, anatids, rallids, phalacrocoracids, threskiornithids, gruids, pelecanids).

By taking an agnostic approach host status, indicates relatively large, CIPBR-wide pool landscapes, challenging narrow view is limited birds. In addition, findings highlight for leveraging high-risk geographic guide landscape-specific selection surveillance.

ABSTRACT Motivation The accelerated and widespread conversion of once continuous ecosystems into fragmented landscapes has driven ecological research to understand the response biodiversity local (fragment size) landscape (forest cover fragmentation) changes. This information important theoretical applied implications, but is still far from complete. We compiled most comprehensive updated database investigate how these changes determine species composition, abundance trait diversity multiple taxonomic groups in forest fragments across globe. Main Types Variables Contained gathered data for 1472 fragments, providing on composition 9154 belonging vertebrates, invertebrates, plants. For 2703 species, we obtained more than 20 functional traits. provided spatial location size each fragment metrics configuration. Spatial Location Grain dataset includes sampled 121 studies all continents except Antarctica. Most datasets (77%) are tropical regions, 17% temperate 6% subtropical regions. Species were collected at plot or scale, whereas extracted with buffer ranging a radius 200–2000 m. Time Period Data community between 1994 2022, same year that given study data. Major Taxa Level Measurement studied organisms included invertebrates (Arachnida, Insecta Gastropoda; 41% datasets), vertebrates (Amphibia, Squamata, Aves Mammalia; 44%), vascular plants (19%), lowest level identification was morphospecies.

This is case of parasites such as avian haemosporidians which naturally infect birds and are transmitted by insect vectors.

We studied effects landscape structure environmental variables on prevalence richness lineages haemosporidian (genera Plasmodium, Haemoproteus Leucocytozoon) infecting a highly diverse area Antioquia, Colombia. screened blood samples from 678 individuals across 90 bird species for number infections, sites surrounding three hydroelectric dams. obtained around sampling points scales (from 50 500 m radii, every m) selected most important ones. modelled relationships between parasite infection structural characteristics.

ABSTRACT Understanding how three‐dimensional (3D) habitat structure drives biodiversity patterns is key to predicting alteration and loss will affect species community‐level in the future. To date, few studies have contrasted effects of 3D composition with those configuration on biodiversity, existing investigations often limited measures taxonomic diversity (i.e., richness). Here, we examined influence Light Detecting Ranging (LiDAR)‐derived structure–both its configuration–on multiple facets bird diversity. Specifically, used data from National Ecological Observatory Network (NEON) test associations between 11 avian richness, functional trait diversity, phylogenetic We found that was most consistent predictor little no effect richness or Functional individual characteristics were strongly associated both configuration, but magnitude direction varied across canopy, subcanopy, midstory, understory vertical strata. Our findings suggest influences through traits. By examining aspects provide a broader framework for future structure.

Habitat fragmentation is causing the collapse of seed dispersal interactions and ecosystem functioning. When management conservation strategies aim to sustain functioning fragmented forests, species’ traits functional performance are critical in guiding decisions. However, date, we lack a quantitative understanding role frugivores’ body size ability sustainability among forests. Focusing on avian frugivory multi-island setting, address data gap by recording more than 20,000 events an artificial insular landscape constructed 1959 nearby unfragmented forests mainland. We show that large-bodied dispersal-limited frugivorous birds largely confined large islands mainland, whereas small islands, small-bodied highly mobile predominantly engage interactions. The plant–frugivore meta-network exhibits distinct compartmentalization, driven island area bird mobility. Birds with smaller greater mobility have higher topological importance, presence significantly enhances robustness. These results suggest where degraded, disproportionately contribute meta-community cohesion because birds. thus advocate for restoration landscapes facilitate connectivity, ensuring patches along as stepping-stones. Meanwhile, recommend prioritizing landscapes, subset underappreciated species yet play crucial roles
