The spatial variation of Asian dust and marine aerosol contributions to glaciochemical signals in central Asia [PDF]

open access: yes, 1992
Short-term (6 months to 17 years) glaciochemical records have been collected from several glacier basins in the mountains of central Asia. The spatial distribution of snow chemistry in central Asia is controlled by the influx of dust from the large ...

Phylogenomics and Biogeography of the Eastern Asian–Eastern North American Disjunct Genus Hylodesmum (Fabaceae)

open access: yesBiological Diversity, EarlyView.
Integrating data from plastid genomes, nrDNA, and 353 low‐copy nuclear genes, this study establishes a robust phylogenetic framework for Hylodesmum. This framework supports a taxonomic revision recognizing 18 species and reveals a complex pattern of bidirectional EA–ENA dispersal, with mammals as a plausible dispersal agent. ABSTRACT Phylogenomics with

A Systematic, Regional Assessment of High Mountain Asia Glacier Mass Balance

open access: yesFrontiers in Earth Science, 2020
High-mountain Asia (HMA) constitutes the largest glacierized region outside of the Earth's polar regions. Although available observations are limited, long-term records indicate sustained HMA glacier mass loss since ~1850, with accelerated loss in recent

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Extent, characteristics and policy applications of Key Biodiversity Areas

open access: yesBiological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Ecology of the non-native snail Sinotaia cf quadrata (Caenogastropoda: Viviparidae). A study in a lowland stream of South America with different water qualities [PDF]

open access: yes, 2017
Sinotaia quadrata is a snail native from Asia recorded for the first time in South America in 2009 in central Argentina. In 2015, this species was also found in a lowland stream with different water qualities. Our aims were to contribute to the knowledge

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

open access: yesBiological Reviews, EarlyView.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Geodiversity is an inseparable but underutilized aspect of ecological connectivity assessments under climate change

open access: yesEcography, EarlyView.
Conservation has shifted towards a climate change adaptation approach in which expected species range shifts are increasingly considered to mitigate effects of climate change and habitat fragmentation on biodiversity. As part of this, ecological connectivity needs to be ensured to support gene flow and viable populations in the face of changing ...

Warming, increase in precipitation, and irrigation enhance greening in High Mountain Asia

open access: yesCommunications Earth & Environment, 2022
Greening in high mountain Asia between 2003 and 2020 was driven by warming at high elevations, increased precipitation in forested regions and enhanced irrigation in croplands, according to a multivariate analysis of remote sensing data.
