How Does the Phasianidae Maintain Its Diversity in Central China?

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
ABSTRACT The hypothesis of allopatric speciation suggests that spatial separation is the major driver to speciation. The ecological niche theory suggests that differentiations in niche dimensions allow more species to co‐exist in ecological communities.

Clay Mineralogy of Red Clay Deposits from the Central Carpathian Basin (Hungary): Implications for Plio/Pleistocene Chemical Weathering and Paleoclimate

open access: yes, 2013
Geochemical and mineralogical studies of palaeosols provide essential information for palaeoclimatic and palaeoenvironmental interpretation of continental deposits and can present a proxy for palaeoclimate.

An integrated biostratigraphy and seismic stratigraphy for the late Neogene continental margin succession in northern Taranaki Basin, New Zealand

open access: yes, 2006
Our aim has been to develop an integrated biostratigraphy and seismic stratigraphy for the Pliocene and Pleistocene formations (Ariki, Mangaa, Giant Foresets) in northern Taranaki Basin to better understand the evolution of the modern continental margin ...

Oxytropis ikhbogdicus (Section Mesogaea, Fabaceae), A New Species From Mongolia Based on Morphological and Molecular Analyses

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Oxytropis ikhbogdicus, a new species endemic to Mongolia, is described and illustrated. The new species was confirmed by phylogenetic analysis based on the complete plastome genome and combined nuclear ribosome internal transcribed spacer (ITS), psbA‐trnH, and trnF‐L sequence data as well as morphological characteristics. ABSTRACT Oxytropis ikhbogdicus,

Pliocene primates.

open access: yes, 2017
The Pliocene fossil record is dominated by Old World monkeys and hominins. Pliocene lemur, loris, tarsier, New World monkey, and great ape fossils are nonexistent, and very few fossils of galagos and gibbons have been found. All known Pliocene primate fossils can be assigned to modern families; the sivaladapids and pliopithecids, ancient primate groups

Phylogenetic and Environmental Insights Into the Biogeography of the Western Blacknose Dace, Rhinichthys obtusus

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Pleistocene glaciations have shaped freshwater fish evolution and distribution patterns across North America. This study investigated the phylogeographical history of the Western Blacknose Dace (Rhinichthys obtusus) using mitochondrial genomic data, revealing three major clades that diverged 2–1.5 million years ago during Pleistocene glaciations when ...

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

open access: yesEcography, Volume 2026, Issue 6, June 2026.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

Planktic foraminiferal evidence for variation in the strength of the Agulhas Current during the Pliocene (4.6-2.6 Ma)

open access: yesJournal of the Palaeontological Society of India
The Pliocene, although predominantly warm, experienced four major glacial events at 4.8, 4.0, 3.3, and 2.7 million years ago (Ma), altering ice sheet dynamics and ocean circulation.

Rapid changes of the lava‐delta coastlines formed by the 2021 volcanic eruption on La Palma, Canary Islands

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
A new coastline formed during the 2021 eruption of La Palma quickly eroded, becoming crenellated and with pocket beaches, then retreated more gradually as resistant interiors of the lava were exposed. In contrast, a second thicker lava delta changed more gradually, highlighting the importance of lithology to coastal erosion.

Observations of coastal cliff landslide runout in southern California from 21 years of data

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
Runout distance from coastal cliff landslides along the coast of northern San Diego County, California USA between 2001 and 2023 were mapped and quantified. Results indicated cliff height influenced runout distance, and that 98% of maximum runout distances were less than half the cliff height.
