Fog, Symbiosis, and Survival: The Ecological Architecture of the Grit Crust From the Atacama Desert Represents a Lichen Holobiome Rather Than a Soil Microbiome

Environmental Microbiology, Volume 28, Issue 6, June 2026.
Multi‐marker metabarcoding (16S rRNA, 18S rRNA, ITS2) of the fog‐dependent grit crust in the Atacama Desert reveals a community structured by lichen symbioses rather than typical soil‐derived microbial assemblages. The green algal photobiont Trebouxia dominates the eukaryotic community, accompanied by lichenized Caliciales and lichen‐associated ...

Environmental Heterogeneity Predicts Behavioural Diversity in a Widely Distributed Group of Marine Carnivores

Diversity and Distributions, Volume 32, Issue 5, May 2026.
ABSTRACT Aim Environmental heterogeneity shapes species diversity by creating ecological niches (habitat heterogeneity hypothesis). Yet its role in driving behavioural diversity within species remains only partially understood. Behavioural diversity enhances a population's ability to exploit ecological niches and adapt to environmental change, making ...

Avian influenza overview December 2025–February 2026

EFSA Journal, Volume 24, Issue 3, March 2026.
Abstract Between 29 November 2025 and 27 February 2026, 2514 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (406) and wild (2108) birds in 32 countries in Europe. Albeit still at high levels after the peak was reached at the beginning of the current reporting period, the weekly number of detections has since ...

Anembryonic gestation in wild South American sea lion, Otaria flavescens [PDF]

, 2015
We present the first record and description of an anembryonic gestation in a wild South America sea lion, Otaria flavescens (Carnivora, Pinniped). This is the first report of an anembryonic gestation in a wild marine mammal species.

Intraguild predation in sympatric seals and the effect on a declining population

Journal of Animal Ecology, Volume 94, Issue 12, Page 2572-2583, December 2025.
This study examined the prevalence, spatial extent, and temporal trends of grey seal intraguild predation (IGP). We demonstrated the utility of integrating disparate datasets to address conservation challenges and highlighted how IGP, while seemingly rare, can hold sympatric species in a predator‐pit and in small populations may contribute to declines.

Population structure and historical demography of South American sea lions provide insights into the catastrophic decline of a marine mammal population [PDF]

Royal Society Open Science, 2016
Understanding the causes of population decline is crucial for conservation management. We therefore used genetic analysis both to provide baseline data on population structure and to evaluate hypotheses for the catastrophic decline of the South American ...

Individual variation in animal communication: from species averages to unique voices

Biological Reviews, Volume 100, Issue 6, Page 2625-2640, December 2025.
ABSTRACT The comparative study of communicative behaviour in non‐human animals, especially primates, has yielded crucial insights into the evolution of human language. This research, mostly focused on the species and population level, has improved our understanding of the various socio‐ecological factors that shape communication systems.
