Turning Mediterranean Farmlands Into Priority Habitats: Natural Expansion of Juniper Woodlands After Agricultural Abandonment

open access: yesJournal of Vegetation Science, Volume 37, Issue 3, May/June 2026.
Spanish juniper woodlands are expanding across central Spain as farmland is abandoned. By combining 34 years of land‐cover data with high‐resolution photogrammetry and field measurements, we show that juniper growth depends on topography, solar exposure and competition with shrubs. High irradiance increases biomass in older stands but limits young ones,

Unravelling the drivers of island species richness in tropical savannas

open access: yesJournal of Ecology, Volume 114, Issue 4, April 2026.
Murundu island area explains a substantial proportion of the variation in tree and herb richness, consistent with Island Biogeography Theory. On average, a 10% increase in island size corresponds to increases of seven tree species and 7.8 herb species.

Multiscale Environmental Drivers of Aquatic Insect Assemblages in Cerrado Streams

open access: yesAustral Ecology, Volume 51, Issue 3, March 2026.
Multi‐scale drivers of aquatic insect communities in Cerrado streams. The gradient (from left to right) indicates increasing spatial scale, showing that abundance is influenced by local factors (conductivity, temperature), taxonomic richness responds to agricultural land use at an intermediate scale, and community composition is structured by regional ...

Abordagens atuais em biogeografia marinha.

open access: yesRevista da Biologia, 2011
Marine biogeography focuses on the history of geographic distribution of marine taxa, with areas of endemism and generalized tracks as basic units of analysis. Studies in marine biogeography are incipient for the majority of marine taxa, mainly because of difficulties in characterizing and understanding the barriers that causes cladogenesis of the ...

Ecological and Spatial Drivers of Diversification and Hybridization in Phalacrocarpum (Anthemideae, Asteraceae)

open access: yesJournal of Biogeography, Volume 53, Issue 2, February 2026.
ABSTRACT Aims Range shifts and niche differentiation can promote hybridization and homoploid hybrid speciation by bringing different lineages into contact and afterwards facilitating their reproductive isolation. The Iberian endemic angiosperm genus Phalacrocarpum is a suitable model to explore these processes.

Habitat Amount Shapes Ant Diversity in the Central Amazon

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
Ant diversity in fragmented Amazonian forest landscapes is primarily driven by landscape‐scale habitat amount rather than fragment size, supporting the Habitat Amount Hypothesis (HAH) over Island Biogeography Theory (IBT). Consequently, conservation strategies should prioritize maintaining and restoring forest cover across human‐modified landscapes ...
