Riqueza e endemismo de espécies de Baptistonia (Orchidaceae), no Brasil

Hoehnea
O endemismo e a riqueza das espécies são medidas complementares da biodiversidade e atributos úteis para uma definição eficaz de áreas de preservação. Estes atributos são aqui aplicados à FlorestaAtlântica brasileira, baseados em um grupo de orquídeas ...

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

Ibis, Volume 168, Issue 3, Page 972-984, July 2026.
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 ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

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 ...

Trade and socioeconomic importance of an invasive giant snail in the endemic‐rich island of São Tomé, Central Africa

Conservation Biology, Volume 38, Issue 5, October 2024.
Abstract Managing invasive species is crucial to mitigate their negative impacts on ecosystems, yet conflicts may arise when their social benefits are disregarded. Human pressure on the endemic‐rich forests of São Tomé has been high since the island was discovered by the Portuguese in the 15th century, and numerous species have been introduced.
