fastbioclim: An R package for creating custom‐time bioclimatic and derived environmental summary variables

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 5, Page 1585-1594, May 2026.
Abstract Bioclimatic variables, widely used in ecological and biogeographical studies, are typically derived from 30‐year averages of monthly data (e.g. 1971–2000). Unfortunately, the use of these long‐term averaged variables often creates a temporal mismatch with the observational data collected, which potentially undermines how environmental ...

Into the Darkness: Unveiling Unexpected Records of the Nonnative Millipede Prosopodesmus jacobsoni Silvestri, 1910 (Polydesmida: Haplodesmidae) in Brazilian Caves

open access: yesAustral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT This study expands the known distribution of the nonnative millipede Prosopodesmus jacobsoni in Brazil and reports its presence in cave environments for the first time in the country. Based on recently collected material and historical records, the species is shown to maintain stable populations in subterranean systems in the states of ...

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.

De Humboldt a Darwin: una inflexión clave en la historia de la biogeografía

open access: yesGeosul, 2008
  Comparada con la biogeografía humboldtiana, las tesis biogeográficas que Darwin desarrolla en El Origen de las Especies presentan dos novedades importantes. La primera de ella es teórica: para Darwin la distribución actual de los seres vivos está más

ECOLOGICAL BIOGEOGRAPHY: A REVIEW WITH EMPHASIS ON CONSERVATION AND THE NEUTRAL MODEL BIOGEOGRAFIA ECOLOGICA: REVISION CON ENFASIS EN CONSERVACION Y EL "MODELO NEUTRAL" BIOGEOGRAFIA ECOLOGICA: REVISION CON ENFASIS EN CONSERVACION Y EL "MODELO NATURAL"

open access: yesGayana, 2008
Ecological biogeography studies the factors that define the spatial distribution of species in the present time. This review summarises recent contributions on ecological biogeography. Most recent articles report environmental factors such as temperature,

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 ...
