Bryophyte diversity patterns in flooded and tierra firme forests in the Araracuara Region, Colombian Amazonia [PDF]

open access: yes, 2004
We investigated patterns of bryophyte species richness and composition in two forest types of Colombian Amazonia, non-flooded tierra firme forest and floodplain forest of the Caquetá River.

Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

open access: yesPeople and Nature, EarlyView.
Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

Exploring Costa Rica's fungal trends: Insights from digitized specimens

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
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.

External structures at the nest‐site predict asymmetric architecture of nests in a mud‐building bird

open access: yesIbis, EarlyView.
In the animal kingdom, nests are essential structures and textbook examples of extended phenotypes. However, the relationship between builders, nest traits and the nest‐site remains poorly understood. We indirectly examine whether structures in the nest‐site influence nest‐building behaviour, specifically focusing on their effect on nest architecture ...

Contrasting mechanisms driving the northward expansion of African raptors in Europe

open access: yesJournal of Zoology, EarlyView.
Recent climate warming and landscape changes are enabling African raptors to reach Europe through contrasting mechanisms. Using species distribution models, we show that the Atlas Long‐legged Buzzard expands northward following climatic suitability, whereas African vultures reach Europe despite low climatic favourability through socially mediated ...

Extensión de la distribución geográfica de Mesoscincus altamirani (Squamata: Sauria: Scincidae) en el estado de Guerrero, México

open access: yesRevista Mexicana de Biodiversidad, 2011
La distribución de Mesoscincus altamirani en el estado de Guerrero se amplía significativamente al este del único registro conocido. Se amplían también, el intervalo altitudinal y la talla máxima (longitud hocico-cloaca, longitud de la cola y longitud ...
