Next-generation phylogeography reveals unanticipated population history and climate and human impacts on the endangered floodplain bitterling (Acheilognathus longipinnis)

BMC Ecology and Evolution
Background Floodplains harbor highly biodiverse ecosystems, which have been strongly affected by both past climate change and by recent human activities, resulting in a high prevalence of many endangered species in these habitats.

Subsurface Investigations of Cryo‐Hydrogeological Features in a High Arctic Catchment Under Transition

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...

Effects of Surface Characteristics on the Existence of Isolated Permafrost in Northeastern Mongolia

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Isolated patches of permafrost, where ground thermal changes are affected by ecosystem factors such as vegetation cover rather than climate, may be vulnerable to environmental disturbances in semiarid regions. However, the impacts of ecosystem factors remain underevaluated in Mongolia.

Ecomorphological correlates of twenty dominant fish species of Amazonian floodplain lakes

Brazilian Journal of Biology
Fishes inhabiting Amazonian floodplain lakes exhibits a great variety of body shape, which was a key advantage to colonize the several habitats that compose these areas adjacent to the large Amazon rivers.

Permafrost Terrain Disturbance Susceptibility in the Nacho Nyäk Tagé (Stewart River) Watershed, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The Nacho Nyäk Tagé (Stewart River) watershed in central Yukon (Canada) is characterized by discontinuous permafrost that is locally highly sensitive to thaw. This study aims to map the spatial distribution of permafrost terrain disturbances (PTDs) in the watershed and model thaw susceptibility to support community‐led land‐use planning by the

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Preparation of Seven Certified Reference Materials for Floodplain Sediments

Yankuang ceshi, 2018
BACKGROUND Floodplain sediment, which is an important sampling media for geochemical mapping, can represent the average distribution of elements in the basins and has universal applicability. At present, there is no floodplain sediment reference material

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, EarlyView.
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.

Multifactorial analysis of the geochemical characterization in a Brazilian hypersaline floodplain

Brazilian Journal of Aquatic Science and Technology, 2014
Hypersaline floodplains (sabkhas or saltflats) consist of the supratidal plains with low input of clastic sediments, high evaporation rates, and crustal salts. These environments are prone to periodical floodings and evaporite deposition, common in coastal areas with flat topography of arid regions, developing in response to two environmental ...
