pylifemap: Mapping data onto the tree of life

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract The need to visualize data associated with NCBI Taxonomy Identifiers is growing in various biological fields ranging from comparative genomics to metagenomics and metabarcoding, and even for outreach. No tool today allows visualization of such data while still keeping the full vision of the whole taxonomy, possibly causing a biased view of the

Comparative review of entanglement risk assessments for cetacean conservation and management

open access: yesConservation Biology, EarlyView.
Abstract Cetacean entanglement in fishing gear remains a major global threat that exposes persistent gaps in how fisheries management frameworks manage risk to nontarget species. Ecological risk assessment (ERA) offers a structured way to link exposure and consequences to an explicit statement of risk, but entanglement risk assessments vary widely in ...

Accelerated Evolution of Limb-Related Gene Hoxd11 in the Common Ancestor of Cetaceans and Ruminants (Cetruminantia)

open access: yesG3: Genes, Genomes, Genetics, 2020
Reduced numbers of carpal and tarsal bones (wrist and ankle joints) are extensively observed in the clade of Cetacea and Ruminantia (Cetruminantia). Homebox D11 (Hoxd11) is one of the important genes required for limb development in mammals. Mutations in

Evolutionary and Ecological Determinants of the Phenology of Births in Wild Large Herbivores, a Systematic Review

open access: yesMammal Review, Volume 56, Issue 2, June 2026.
This semi‐systematic review supports the two dominant drivers of birth phenology: the seasonality and predation hypotheses. Even though there is evidence of their importance, the effects of female, offspring and population characteristics remain marginally accounted for. Asian and South and Central American species are currently understudied.
