Sources of Variation in Fecal Haptoglobin in a Population of Wild Capuchin Monkeys (Cebus imitator)

American Journal of Primatology, Volume 88, Issue 6, June 2026.
Fecal haptoglobin values show significant seasonal variation in wild capuchin monkeys. Values are highest, and most variable in the early‐mid dry season, when fruit is typically scarce and water sources are standing pools, which can accumulate pathogens.

Testing VIPV Curved Modules: Methods and Challenges

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 6, Page 744-757, June 2026.
This work presents procedures and equipment for characterizing curved vehicle‐integrated photovoltaic (VIPV) modules through STC I–V curve and relative angular response (RAR) measurements. Outdoor measurements are compared with indoor measurements obtained using a collimated‐light solar simulator, showing excellent agreement for STC I–V curves.

Ciclos climáticos e causas naturais das mudanças do clima

Terrae Didatica, 2018
A periódica mudança climática na Terra pode ser explicada por um número reduzido de fatores terrestres e astronômicos. Nas escalas anual/diária, o clima obedece aos movimentos de translação e de rotação.

Landscape forest cover, not edge contrast, modulates edge effects on palm diversity

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our findings demonstrate that landscape forest cover plays a critical role in modulating edge effects in plant communities in our study system, but not all woody crops systems provide buffering benefits, as cacao plantations in our study failed to soften edge effects.

Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, Volume 250, Issue 5, Page 2778-2813, June 2026.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Análise de rendimento do sistema de bombeamento de água por energia solar fotovoltaica para irrigação de um viveiro de mudas

Vértices, 2019
O Brasil possui grande potencial de radiação solar devido a sua localização geográfica, sendo assim a energia solar fotovoltaica (ESFV) aparece como alternativa sustentável para produção de eletricidade. Dentre as aplicações da ESFV está o bombeamento de

The interplay between hydraulic capacitance and stomatal regulation strategy affects soil–plant hydraulics and transpiration

New Phytologist, Volume 250, Issue 5, Page 2988-3000, June 2026.
Summary Plant water storage contributes to transpiration, but it is unclear how its relevance in supporting transpiration depends on the stringency of stomatal regulation. Here, we show the compounding effect of stomatal regulation and hydraulic capacitance on plant water use, by means of a soil–plant hydraulic model and measurements of leaf water ...
