Male‐Biased Dispersal Leads to Expansion After Decline: The Hokkaido Brown Bear (Ursus arctos) Population Rebounds Post‐Last Glacial Period

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Sex‐biased dispersal potentially underpins the genetic structural mismatch in genetic structure between differently inherited genetic loci. To understand how such a mismatch has formed, we conducted genetic analysis of the brown bear in Hokkaido, Japan, with significant genetic differences between maternally and paternally inherited loci. We found that

Climatic niche divergence and high‐elevation adaptation promoted rapid diversification of Pimoa spiders in Pan‐Himalaya

Ecography, Volume 2026, Issue 9, September 2026.
The Pan‐Himalayan region harbors exceptional biodiversity, yet the origins and underlying mechanisms driving this remarkable diversity remain poorly understood, especially among species‐rich invertebrates. Pimoa spiders exhibit an intercontinental disjunct distribution across three major mountain regions: the Rockies, the Alps, and the Pan‐Himalaya ...

A review of paleoclimate reconstruction based on soil physical and chemical properties

Guan'gai paishui xuebao
Soils preserve critical geochemical and mineralogical information that records past climatic conditions. Consequently, soil physical, chemical, and biological properties have become important proxies for paleoclimate reconstruction.

Peatlands at Southernmost Permafrost Edge: Rapid Carbon Accumulation but High Vulnerability to Drying

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Little Ice Age cooling promoted peat initiation and permafrost development at the southern permafrost margin. Rapid carbon accumulation was sustained by permafrost‐suppressed decay and high photosynthetically active radiation, but recent warming‐driven drying is reducing carbon accumulation and increasing carbon‐loss risk.

Leaf wax n-alkane distributions in Chinese loess since the Last Glacial Maximum and implications for paleoclimate

, 2016
Leaf wax n-alkanes have been recently introduced into loess deposits for paleovegetation and paleoclimate reconstruction. However, the paleoclimate significance of some n-alkane parameters such as chain-length ratios (L/H, C-27/C-31, C-29/C-31, and (C-27

The Usage History of the Aqueduct of Nîmes Reconstructed From Carbonate Archives: Operation, Modifications and Late Antique Breakdown and Change

Geoarchaeology, Volume 41, Issue 5, September/October 2026.
ABSTRACT Anthropogenic carbonate deposits in Roman aqueducts can provide detailed environmental and archaeological information. The Roman aqueduct of Nîmes (France), famed for the Pont du Gard bridge, was built around AD 50 to convey water over 50 km to the city of Nemausus for drinking and bathing.

The Problem with High Elevation Pollen Paleoclimate Proxies

, 2015
The Florissant Fossil Beds National Monument is dated to latest Eocene, making it very important to paleoclimate models. We used the Coexistence Approach (CA) to determine the mean annual temperature (MAT) using both paleobotanical macrofossils and ...

Nonstationary Australasian Teleconnections and Implications for Paleoclimate Reconstructions [PDF]

, 2013
The stationarity of relationships between local and remote climates is a necessary, yet implicit, assumption underlying many paleoclimate reconstructions.

Using dendroclimatic analysis of exotic deciduous conifers in an arboretum to document tree growth in response to climate change, Northeast Ohio, USA

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1746-1762, September 2026.
Rising temperatures and wetter conditions in the Midcontinent of North America are influencing climate responses in trees. Dendroclimatological analyses of four exotic deciduous conifer species from Secrest Arboretum, Northeast Ohio help identify past, present and future climate‐tree interactions.
