Phylogeny and Biogeography of Calanthe Shed New Light on Alpine Origin and Radiation History of Calanthe Alliance

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Using nrITS, plastome, and single‐copy SNP data, we resolved the phylogeny of the Calanthe alliance, which originated in the late Oligocene. Its diversification process followed a two‐step pattern: first the warmest Cenozoic interval and Himalayan uplift drove the formation of three major lineages, then sustained Miocene cooling shaped further ...

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

open access: yesEcography, Volume 2026, Issue 3, March 2026.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Aquatic Biodiversity in the Amazon: Habitat Specialization and Geographic Isolation Promote Species Richness

open access: yesAnimals, 2011
The Neotropical freshwater ichthyofauna has among the highest species richness and density of any vertebrate fauna on Earth, with more than 5,600 species compressed into less than 12% of the world’s land surface area, and less than 0.002% of the world’s ...

Evolution and loss of long-fringed petals [PDF]

open access: yes, 2012
Background: The Cucurbitaceae genus Trichosanthes comprises 90–100 species that occur from India to Japan and southeast to Australia and Fiji. Most species have large white or pale yellow petals with conspicuously fringed margins, the fringes sometimes ...

Genetics in the Ocean's Twilight Zone: Population Structure of the Silvery Lightfish Across Its Distribution Range

open access: yesEvolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT The large estimates of mesopelagic fish biomass have long fuelled harvesting interests in the relatively untouched twilight zone of the ocean. The silvery lightfish—one of the most abundant species inhabiting the North Atlantic mesopelagic layer—is a candidate for such a fishery despite its enormous ecological importance and the insufficient ...

Tertiary Climate Change and the Diversification of the Amazonian Gecko Genus Gonatodes (Sphaerodactylidae, Squamata) [PDF]

open access: yes, 2008
The genus Gonatodes is a monophyletic group of small-bodied, diurnal geckos distributed across northern South America, Central America, and the Caribbean.

A summary of the endemic beetle genera of the West Indies (Insecta: Coleoptera); bioindicators of the evolutionary richness of this Neotropical archipelago [PDF]

open access: yes, 2012
The Caribbean Islands (or the West Indies) are recognized as one of the leading global biodiversity hot spots. This is based on data on species, genus, and family diversity for vascular plants and non-marine vertebrates.

Combining Historical and Ecological Methods Provides New Insights for the Recognition of Biogeographical Areas and Their Relationships: The Case of the Gulf of Mexico

open access: yesJournal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim Biogeographical regionalisation is an evolutionary system of nested areas representing the geographic organisation of life on the planet, which is fundamental for understanding basic and applied aspects related to the ecology, evolution and conservation of biotas and their habitats.

Ancestral Biogeography Reveals Diverse Origins of Costa Rica Margin Seep Invertebrates

open access: yesJournal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim This work addressed the hypotheses that invertebrate species from hydrocarbon seeps at the Pacific Costa Rica Margin (CRM) would descend from adjacent biogeographic provinces, and that common ancestral histories would be identified across invertebrate groups.
