Asimetría fluctuante como un indicador de estrés ambiental en pequeños mamíferos [PDF]

open access: yes, 2017

Environmental Stress Drives Plasticity in Sexual Bimaturism in the Black Soldier Fly (Hermetia illucens Linnaeus, 1758)

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We measured the plasticity in sexual bimaturism (SBM; differences between sexes in the timing of sexual maturity) in the black soldier fly (BSF) by exposing larvae to nutrient availability and humidity stress. Our results show that SBM can range between protandry and protogyny depending on the environmental quality. Additionally, we found the degree of

Ecological and functional effects of habitat conversion and seasons on fruit‐feeding butterfly assemblages in tropical dry forests Efeitos ecológicos e funcionais da conversão do habitat e da sazonalidade sobre assembleias de borboletas frugívoras em florestas tropicais secas

open access: yesEcological Entomology, EarlyView.
Land‐use change and seasonality shape the taxonomic, functional and phylogenetic diversity of fruit‐feeding butterflies in tropical dry forests. Pastures reduce phylogenetic diversity and increase wing fluctuating asymmetry, while taxonomic and functional diversity is greater in the wet season than in the dry season.

What is hidden under our pontoons? Abundance and distribution of filter feeders (bivalves and tunicates) in the port area revealed. Artificial intelligence: an interesting analysis tool?

open access: yesFrontiers in Marine Science
Urbanization is particularly prevalent along the coast, causing a considerable change in the ecology of the habitats found there. Ports, docks and all the structures linked to this anthropization modify the coastal environment by providing new niches ...

Critical tipping points in dung beetle communities: Implications for conservation in the Atlantic Forest biome

open access: yesInsect Conservation and Diversity, EarlyView.
Minor land‐use changes consistently lead to abrupt biodiversity shifts across all diversity dimensions, favoring generalist dung beetle species while excluding sensitive specialists. These shifts are observed at lower environmental change rates than previously considered, with significant changes apparent after just 25% habitat loss.

Trechus (Coleoptera: Carabidae) of Appalachia: A Phylogenetic Insight into the History of High Elevation Leaf Litter Communities

open access: yesDiversity
Elevation gradients provide a wealth of habitats for a wide variety of organisms. The southern Appalachian Mountains in eastern United States are known for their high biodiversity and rates of endemism in arthropods, including in high-elevation leaf ...

Impacts of land use change on diaspore‐dispersing ant assemblages in southwestern Amazonia

open access: yesInsect Conservation and Diversity, EarlyView.
Land use changes shift ant assemblages, more intensive land uses are dominated by generalist and open habitat specialist species engaging in group foraging. The diaspore removal rates cannot differ, but the quality of dispersal was lower in disturbed habitats.

Sheep and cattle grazing regimes differentially affect ground beetle and ant communities in Mediterranean cork oak woodlands

open access: yesInsect Conservation and Diversity, EarlyView.
Sheep and cattle grazing significantly shape ant and ground beetle species composition in Mediterranean cork oak woodlands, promoting higher diversity by increasing habitat heterogeneity. Ground beetles and ants reflect changes in grazing regimes, with sheep‐grazed areas showing the highest diversity, highlighting their utility in ecosystem monitoring.

Heavy metal accumulation in Artemisia and foliaceous lichen species from the Azerbaijan flora [PDF]

open access: yes, 2006
Artemisia plants and foliaceous lichens are known to be capable of accumulating heavy metals (HM) from soil and air. These plant species are widespread on polluted sites of Azerbaijan.

Fly me to the canopy: Diptera communities in oak forest crowns as bioindicators of stand decline

open access: yesInsect Conservation and Diversity, EarlyView.
Diptera diversity: Oak decline increases the overall Diptera diversity, particularly in saproxylic and floricolous guilds, likely due to more open canopies and greater deadwood and floral resource availability. Family responses: Dolichopodidae, Empididae, Hybotidae and Anthomyiidae thrive in declining stands, whereas Mycetophilidae and other fungus ...
