High and dry: Environmental conditions drive opportunities for disease transmission in desert bighorn sheep

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
By using probabilistic models to predict contacts as a function of spatially and temporally varying environmental conditions, we show that population‐level conditions at the time of disease introduction can structure opportunities for transmission within each population.

Persistência do fungicida triadimenol em solos

open access: yesRevista Brasileira de Ciência do Solo, 1998
O grau de persistência do fungicida triadimenol, que é utilizado intensamente no controle da ferrugem do cafeeiro, foi avaliado em amostras de duas classes de solo, Podzólico Vermelho-Amarelo câmbico (PV) e Latossolo Vermelho-Amarelo variação Una (LU) da

Little devils of Neotropical forests: A first molecular phylogeny of stygnid harvestmen with UCE‐museomics and a gigamatrix approach (Arachnida, Opiliones, Stygnidae)

open access: yesSystematic Entomology, Volume 51, Issue 3, July‐September 2026.
First family‐wide phylogenomic framework of Stygnidae using UCE‐museomics and a gigamatrix approach establishes a novel three‐subfamily classification, erecting the new subfamily Auraninae subfam. nov. Signatures of severe incomplete lineage sorting and short deep internodes suggest a rapid early‐burst Neotropical radiation, driving phylogenetic ...

Persistência do acetochlor em solo sob semeadura direta e convencional Acetochlor persistence in soil under no-tillage and conventional systems

open access: yesPlanta Daninha, 2002
O manejo do solo pode alterar a persistência dos herbicidas e influi na atividade para controle de plantas daninhas, no potencial de injúria das culturas em sucessão e no risco de contaminação ambiental.

Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1943-1956, June 2026.
Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

Destino ambiental dos herbicidas do grupo das imidazolinonas: revisão Environmental fate of imidazolinone herbicides: a review

open access: yesPlanta Daninha, 2009
Os herbicidas do grupo das imidazolinonas controlam um amplo espectro de plantas daninhas, sendo absorvidos pelas raízes e folhas e translocados pelo floema e xilema, acumulando-se nos pontos de crescimento.

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

open access: yesFunctional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Role of freshwater availability and terrestrial land‐cover change in the distribution of a declining, terrestrial, insectivorous bird

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Insectivorous, Afro‐Palearctic migrant birds provide cross‐border ecosystem services, but many are declining rapidly. The complex life cycle of migrant birds makes their conservation difficult, but understanding where they spend time during the breeding season can help indicate where those actions will be most effective.

Scenarios and strategies for future‐proofing ecosystem management under climatic novelty

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Climate change is driving unprecedented declines in dominant, habitat‐forming foundation species across marine and terrestrial ecosystems globally. As climatic novelty becomes the norm, ecosystem reassembly will become increasingly common. Predicting and understanding these transitions, and their implications for future ecosystem functioning ...
