Landscape forest cover, not edge contrast, modulates edge effects on palm diversity

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our findings demonstrate that landscape forest cover plays a critical role in modulating edge effects in plant communities in our study system, but not all woody crops systems provide buffering benefits, as cacao plantations in our study failed to soften edge effects.

No size or density effect on alternative mate-locating tactics in the tropical damselfly Hetaerina rosea males (Odonata: Calopterygidae)

Revista de Biología Tropical, 2009
Males of the damselfly Hetaerina rosea may defend mating sites along river margins (resident males) or, alternatively, wander among different areas presumably searching for mates (nonterritorial males).

Role of freshwater availability and terrestrial land‐cover change in the distribution of a declining, terrestrial, insectivorous bird

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Insectivorous, Afro‐Palearctic migrant birds provide cross‐border ecosystem services, but many are declining rapidly. The complex life cycle of migrant birds makes their conservation difficult, but understanding where they spend time during the breeding season can help indicate where those actions will be most effective.

Population structure and accompanying biota of the snail Turbo (Callopoma) funiculosus (Gastropoda: Turbinidae), on Socorro Island, Revillagigedo Archipelago, Mexico

Revista de Biología Tropical, 2006
The porcelain snail, Turbo funiculosus, is a potential fishery resource that almost has not been studied or used commercially. In March of 1992, we sampled T. funiculosus in Bahía Binners and Bahía Blanca, Socorro Island, Revillagigedo Archipelago, using

High Densities of Large Herbivores Rapidly Disrupt Ecosystem Integrity

Global Change Biology, Volume 32, Issue 6, June 2026.
Human‐driven increases in large herbivore populations are emerging as a widespread global change pressure on terrestrial ecosystems. Using the largest hectare‐scale herbivore density manipulation experiment conducted to date, we show that high deer densities rapidly disrupt ecosystem integrity across multiple dimensions of biodiversity and ecosystem ...

Disentangling conservation asymmetries through socio‐economic transboundary factors across the Alto Paraná Atlantic Forest of South America

People and Nature, Volume 8, Issue 5, Page 1328-1348, May 2026.
Abstract Ecoregions are often defined based on homogeneous biophysical and ecological conditions and are optimal spatial units for designing conservation strategies. However, transboundary ecoregions such as the Alto Paraná Atlantic Forest (APAF) experience asymmetrical conservation outcomes, understood here as cross‐border differences, resulting from ...
