When do citizen scientists record biodiversity? Non‐random temporal patterns of recording effort and associated factors

People and Nature, Volume 7, Issue 4, Page 860-870, April 2025.
Abstract Citizen science data are increasingly used for ecological research, biodiversity conservation and monitoring. However, these data often present significant analytical challenges due to uneven recording efforts by citizen scientists. Biases caused by intra‐annual differences in levels of recording activity can be particularly severe, hindering ...

Systematic and taxonomic revision of the genus Austrocactus (Cactaceae) based on morphology and genome wide SNP‐data

TAXON, Volume 74, Issue 2, Page 386-416, April 2025.
Abstract The post‐Miocene climatic history of arid environments in South America has been identified as a key driver of dispersal and diversification, particularly among plant groups such as Cactaceae. Despite their iconic status, many cactus genera remain poorly understood, and comprehensive taxonomic and systematic revisions using morphological and ...

The need for carbon finance schemes to tackle overexploitation of tropical forest wildlife

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract Defaunation of tropical forests, particularly from unsustainable hunting, has diminished populations of key seed dispersers for many tree species, driving shifts in forest community composition toward small‐fruited or wind‐dispersed trees with low wood density. Such shifts can reduce aboveground biomass, prompting calls for overexploitation to

Systematic meteorite collection in the Catalina Dense Collection area (Chile): Description and statistics

Meteoritics &Planetary Science, Volume 60, Issue 2, Page 308-323, February 2025.
Abstract We present the outcome of search campaigns conducted in the Catalina Dense Collection area (DCA) located in the central depression of the Atacama Desert, Chile. The “Catalina Systematic Collection” (CSC) was assembled through systematic on‐foot searches, resulting in a total of 1599 meteorites, before pairing, collected over a surface of 6.80 ...

Microclimatic variation regulates seed germination phenology in alpine plant communities

Journal of Ecology, Volume 113, Issue 1, Page 249-262, January 2025.
This study combines novel laboratory experimentation based on detailed field microclimatic data to tackle the understudied topic of germination phenology in alpine habitats. The findings suggest a predictable phenological shift in the germination of alpine plants along microclimatic gradients.
