New Phytologist, Volume 251, Issue 4, Page 2237-2247, August 2026.Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Investigating Limits in a Vegetation Cover
Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2003 Changes of the environment can be highlighted by changes in the structure of the vegetation cover, which can be detected and their importance measured by the use of Kendall or Kulczinski’s models.

Ecology and Evolution, Volume 16, Issue 7, July 2026.We evaluated whether citizen science–derived camera‐trap records can be used to characterize large‐scale activity patterns of a widely distributed mesocarnivore across heterogeneous landscapes. Using 821 independent iNaturalist records, we quantified activity across six major vegetation types in Mexico with kernel density estimation, circular ...

Exploring Costa Rica's fungal trends: Insights from digitized specimens
PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1256-1274, July 2026.Fungi are essential to tropical ecosystems but remain largely absent from conservation agendas. By analyzing over 78,000 fungal records from Costa Rica—a globally recognized biodiversity hotspot—this study reveals key patterns in fungal diversity, distribution, and seasonality.

Stratégies d’exploitation en zones inondables tropicales
, 2002 Les zones inondables tropicales sont souvent des milieux traditionnellement exploités par l'homme. Pêcheurs, éleveurs, agriculteurs, forestiers et autres sillonnent les milieux inondables dans lesquels les ressources naturelles renouvelables sont abondantes. Les habitants de ces zones ont su pérenniser un mode de vie et d'exploitation en équilibre avec

Mangrove expansion in a large river delta is dependent on foreshore geomorphology
Journal of Applied Ecology, Volume 63, Issue 7, July 2026.Our findings provide guidance for large‐scale mangrove restoration, particularly in tropical river deltas, by identifying sites where (1) mangroves can potentially expand in the future, and (2) conditions are favourable for active mangrove seedling planting. The presence of a mudflat in front of existing mangroves is not sufficient.

Agroforesterie et services écosystémiques en zone tropicale [PDF]
, 2019 Respectueux de l'environnement et garantissant une securite alimentaire soutenue par la diversification des productions et des revenus qu'ils procurent, les systemes agroforestiers apparaissent comme un modele prometteur d'agriculture durable dans les pays du Sud les plus vulnerables aux changements globaux.

Biotropica, Volume 58, Issue 4, July 2026.Forest cover within cattle ranches can strongly shape faunal biodiversity. In Los Tuxtlas, Veracruz, Mexico. We show that butterflies, moths, dung beetles, and birds respond differently to forest cover across habitats (pastures vs. forest fragments) and seasons, as a function of their specialization and resource needs.
