The paper uses genomic data from sea lions to investigate sex-biased dispersal and reproductive skew, finding male-biased migration and varying levels of polygyny between species.

The paper presents a high-quality crabeater seal reference genome and shows it has high genetic diversity, low inbreeding, and a history of population expansion.

The paper uses a decade of sporocarp observations to identify temperature and precipitation triggers for Boletus edulis fruiting in central European beech forests.

The paper shows that early-life environmental conditions affect male Antarctic fur seal recruitment and population dynamics, linking environmental variability to population decline through delayed recruitment strategies.

This study uses high-resolution camera data and a YOLO-based neural network to analyze spatiotemporal density patterns and predator-prey interactions in an Antarctic fur seal colony, revealing how pup predation risk is influenced by proximity to adult seals.

The paper examines how population density affects predator access in Antarctic fur seal colonies using camera data and machine learning.

The paper examines how MHC diversity affects fitness differently in male and female banded mongooses, finding higher diversity increases male fitness but decreases female fitness.

The paper compares skin and gut microbial communities in Antarctic fur seals at different social densities, finding skin communities are more affected by social density than gut communities.

This study evaluates the reuse of microtiter plates for PCR and fragment detection, finding that PCR plates lead to increased genotyping errors while detection plates can be reused without data quality loss.

The paper constructs a haplotype-resolved genome for Boletus edulis using Hi-C and PacBio sequencing, revealing genetic clusters and adaptive regions in European populations.

The paper tests if the marginal male hypothesis combined with density-dependent pup survival can explain density differences between pinniped colonies.

This study investigates the gut microbiota-immune-brain axis in wild common buzzards during early development, finding no direct feedback between microbial diversity and immune/stress parameters but highlighting stress-mediated immunosuppression and the health benefits of microbial diversity.

The paper investigates inbreeding effects on birth mass, survival, and growth in Antarctic fur seal pups and finds no clear or consistent inbreeding depression in these traits.

The paper investigates hybridization in Boletus edulis, finding that ecological preferences, not genome structure, primarily drive reproductive barriers despite ongoing introgression.

This study examines the genetic diversity and demographic history of leopard seals, finding moderate diversity and evidence of population expansion linked to sea ice changes.

This study examines early sexual dimorphism in the gut microbiome of northern elephant seal pups during a six-week post-weaning period, finding significant sex-based differences in microbial diversity and composition.
