Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

Ibis, EarlyView.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Conservação da biodiversidade em pastagens: espécies vegetais em risco [PDF]

, 2008
As plantas herbáceas pratenses surgiram, pela primeira vez, em períodos muito recuados da história evolutiva das plantas com flor. Existem evidências de que no final do Mesozóico existiam já plantas adaptadas à pressão de pastoreio, neste caso por ...

Global insular leaf size shifts follow the island rule, independently of insect herbivory and macroclimate

Journal of Ecology, Volume 114, Issue 2, February 2026.
We found a positive, non‐linear, saturating relationship between mainland and island leaf sizes, reflecting an island rule‐like pattern. Small‐leaved mainland species tend to develop larger leaves on islands, while this effect weakens for larger‐leaved species, a pattern consistent across both conspecific and congeneric comparisons. Abstract The island

Plant conservation in a changing Mediterranean world

PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 49-72, January 2026.
The Mediterranean is one of five climatic regions on the planet characterised by a prolonged summer drought, exceptional plant diversity and high rates of endemism. We provide a framework to link the ecology of plant species conservation in the context of rapid and extreme climate deregulation to a philosophical typology of temporal attitudes (i.e ...

Wintering Together: Do Migrants Impact Residents? A Literature Review

Ecology and Evolution, Volume 15, Issue 2, February 2025.
This review examines the overlooked impacts of interspecific competition on resident tropical birds during the overwintering period, highlighting the need for a deeper understanding of their interactions with migratory species. By evaluating the literature through the lens of competition theory, we identify critical gaps in knowledge and suggest that ...

Unraveling Biogeographic Boundaries Within the Sierra Madre Oriental, México: An Endemicity Analysis Using a Taxonomically Diverse Dataset

Ecology and Evolution, Volume 15, Issue 1, January 2025.
We provide boundaries of the Sierra Madre Oriental in Mexico through a multi‐taxa endemicity analysis. ABSTRACT The Sierra Madre Oriental (SMO) is a significant mountain range and one of Mexico's 14 biogeographical provinces. Its delimitation has been debated.
