Exploring gaps, biases, and research priorities in the evidence for reptile conservation actions

Conservation Biology, Volume 39, Issue 5, October 2025.
Abstract With over 21% of reptile species threatened with extinction, there is an urgent need to ensure conservation actions to protect and restore populations are informed by relevant, reliable evidence. We examined the geographic and taxonomic distribution of 707 studies that tested the effects of actions to conserve reptiles synthesized in ...

Genomics and morphometry of herbarium specimens elucidate the origin of the Cape Verde date palm (Phoenix atlantica A.Chev.) and highlight its agronomic potential

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1358-1371, September 2025.
As climate change accelerates, breeding resilient crops is urgent. The date palm (Phoenix dactylifera L.), a crucial 18 billion USD fruit crop, underpins North African and West Asian oasis agroecosystems. This study investigates the genetics and morphology of its closest wild relative, the endemic and endangered Cape Verde date palm (Phoenix atlantica ...

High extinction risk of the endemic tree flora in a hyper‐diverse region of the Amazon

PLANTS, PEOPLE, PLANET, Volume 7, Issue 4, Page 998-1010, July 2025.
The rapid global loss of biodiversity, especially in the Neotropics, underscores the need to understand how deforestation impacts endemic plant species' extinction risk and conservation status. Due to limited ranges and habitat specialization, endemics are particularly Vulnerable.

Temporal Dynamics of a Neotropical Plant‐Hummingbird Interaction Network

Austral Ecology, Volume 50, Issue 7, July 2025.
Using an unprecedented sampling effort we evaluated network structure and dynamics of plant‐hummingbird interactions over 1 year in the Brazilian hyperdiverse Campos Rupestres. Network structure presented remarkable temporal change, showing that tropical communities can also be strongly influenced by climate.

On the Lack of Domestic Dogs in Pre‐Columbian Lowland Amazonia and Their Deep History of Entanglements With Humans in South America

The Journal of Latin American and Caribbean Anthropology, Volume 30, Issue 2, June 2025.
ABSTRACT Data from archaeology, ethnography, and ethnohistory document entanglements of dogs among South American Indigenous societies during pre‐Columbian and colonial times. The prolific presence and uses of dogs in the Central Andes and in parts of the Paraná Basin, Patagonia, and Circum‐Caribbean regions contrast with the conspicuous lack of ...

Examining the structure of plant–lemur interactions in the face of imperfect knowledge

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract Biotic interactions, such as plant–animal seed dispersal mutualisms, are essential for ecosystem function. Such interactions are threatened by the possible extinction of the animal partners. Using a data set that includes plant–lemur interactions across Madagascar, we studied the current state of knowledge of these interactions and their ...
