Successional and native forests predict the occurrence and infection status of Chagas disease vectors in Panama

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Findings here show that successional forest predicts greater kissing bug infestation risk in palm trees, whereas native forest predicts lower kissing bug occurrence but greater infection with T. cruzi. These insights can guide land use planning towards vegetation management practices that help minimize T. cruzi transmission risks for rural communities.

Evaluating protected areas’ coverage of threats to terrestrial biodiversity

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Protected areas (PAs) are vital for biodiversity conservation and have expanded globally. However, increasing pressures on biodiversity make it difficult to achieve conservation goals. Using threat probability maps based on the International Union for Conservation of Nature Red List and the World Database of Protected Areas, we analyzed the ...

How do drought and elevated temperatures influence CO2 fertilization effects on tree seedling performance? A global meta‐analysis

Journal of Ecology, Volume 113, Issue 10, Page 2875-2888, October 2025.
These results suggest that the fertilization effect of CO2 at the seedling stage may be limited when additional environmental stressors, such as drought, are present. The combined effect of drought, temperature and CO2 mainly resulted in additive effects, where each stressor independently influences plant performance rather than interacting to amplify ...

Influência dos aditivos sobre a permeabilidade e a velocidade de secagem de concretos refratários aplicados por projeção Influence of additives on the permeability and drying behavior of wet shotcrete refractory castables

Cerâmica, 2004
A projeção a úmido de concretos refratários consiste em aplicar o material como um jato de "spray" sobre a superfície, resultando numa elevada taxa de instalação e uma eficiente compactação do material.

Environmental and human factors shape the trophic ecology of a widespread marine predator

Journal of Animal Ecology, Volume 94, Issue 9, Page 1784-1799, September 2025.
Our study reveals how environmental factors and fishing pressure influence swordfish diet, highlighting trophic shifts under future climate scenarios. We provide a novel framework to strengthen our ability to plan for and manage the redistribution of species under global change ensuring that the energetic needs of predators are met.

Rapid Ocean Warming Drives Sexually Divergent Habitat Use in a Threatened Predatory Marine Ectotherm

Global Change Biology, Volume 31, Issue 7, July 2025.
How ectothermic, mobile marine predators are responding to climate change is uncertain due to lack of species‐specific data, which can mask the true impact of this threat. We investigate the impact of environmental conditions and thermal extremes on the behavior and distribution of angelsharks, a highly threatened elasmobranch of global conservation ...

CRIOTOLERÂNCIA DE OÓCITOS E EMBRIÕES BOVINOS MATURADOS COM LÍQUIDO FOLICULAR E/OU ?-MERCAPTOETANOL

Ciência Animal Brasileira, 2015
Foi avaliada a criotolerância de oócitos e embriões bovinos maturados com adição de líquido folicular (LF) e/ou ?-mercaptoetanol (BM). Após vitrificação, os oócitos foram maturados em: TCM-199 (controle); BM (24h TCM-199+100µM BM); LF (6h em LF+18h TCM ...
