Demographic buffering in natural populations: A multi‐level perspective

Journal of Animal Ecology, Volume 95, Issue 8, Page 1298-1310, August 2026.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Environmental detection of the amphibian chytrid fungus in water bodies is associated with host infection along a deforestation gradient

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Linking environmental pathogen detection with host infection patterns can improve surveillance of diseases involving environmental transmission, particularly where direct host sampling is logistically challenging. This approach enables the identification of areas of elevated transmission risk and supports targeted monitoring and management under ...

Predictive factors for sperm retrieval and sperm injection outcomes in obstructive azoospermia: do etiology, retrieval techniques and gamete source play a role?

Clinics
Obstructive azoospermia is a relatively common male infertility condition. The main etiologies of obstructive azoospermia include congenital, surgical-derived, traumatic and post-infectious cases. Although seminal tract reconstruction is a cost-effective

Endogamia e reprodução de bovinos matiqueira da Estação esperimental de zootecnia de Pindaminhangaba

Boletim de Indústria Animal, 2014
Dados de trinta anos, desde a formação do rebanho mantiqueira, em 1952, foram estudados para avaliar o efeito da endogamia nas características de reprodução: idade ao primeiro parto (IPP), intervalo entre partos (IEP), período de serviço (PS), período de gestação (PG) e peso ao nascer do produto (PN).

Reduced fecundity associated with Wolbachia infection in a Neotropical drosophilid Redução da fecundidade associada à infecção por Wolbachia em um drosofilídeo Neotropical

Ecological Entomology, Volume 51, Issue 3, Page 475-488, June 2026.
Using multiple infected and uninfected Drosophila sturtevanti lines, we investigated (i) the impact of Wolbachia on fecundity and (ii) its effects relative to antibiotic treatment. Based on over 1680 dissected ovaries, fecundity was similar between infected and uninfected flies.

Comparison of extenders and storage temperature in chilling canine semen

Ciência Animal Brasileira, 2020
The objective of this study was to evaluate the influence of a commercial milk-based extender compared with a self-made egg yolk extender in the quality of canine semen, stored with two different temperatures (5°C or 15°C) for short-term cooling.

Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

Ecological Entomology, Volume 51, Issue 3, Page 558-569, June 2026.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...
