Niche shifts after long-distance dispersal events in bipolar sedges (Carex, Cyperaceae). [PDF]
American-Eurasian journal of botany, 2017 PREMISE OF THE STUDY Bipolar species represent the greatest biogeographical disjunction on Earth, raising many questions about the colonization and adaptive processes behind such striking distribution.

Plants, 2021 Drought stress is a major environmental constraint for plant growth. Climate-change-driven increases in ambient temperatures resulted in reduced or unevenly distributed rainfalls, leading to increased soil drought. Carex duriuscula C. A. Mey is a typical

Carex delongii (Cyperaceae), a new sedge from Russia
Turczaninowia, 2021 While performing vegetation surveys in the southern part of the Lena delta, a new species of Carex from section Phacocystis has been found. Morphologically, Carex delongii sp. nov. is most close to C. cespitosa and C.

Response of riparian vegetation to short‐ and long‐term hydrologic variation
Ecological Applications, Volume 32, Issue 8, December 2022., 2022 Abstract Increasing demand for river water now conflicts with an increasing desire to maintain riparian ecosystems. Efficiently managing river flows for riparian vegetation requires an understanding of the time scale of flow effects, but this information is limited by the absence of long‐term studies of vegetation change in response to flow variation ...

Characterizing occupational radon exposure greater than 100 Bq/m3 in a highly exposed country
Scientific Reports, 2022 Radon is an established lung carcinogen concentrating in indoor environments with importance for many workers worldwide. However, a systematic assessment of radon levels faced by all workers, not just those with direct uranium or radon exposure, has not ...

Fen ecohydrologic trajectories in response to groundwater drawdown with an edaphic feedback
Ecohydrology, Volume 15, Issue 8, December 2022., 2022 Abstract Fens are high conservation value ecosystems that depend on consistent discharge of groundwater that saturates the near surface for most of the growing season. Reduced groundwater inputs can result in losses of native diversity, decreases in rare‐species abundance and increased invasion by non‐native species.

Journal of Systematics and Evolution, 2021 Changes in holocentric chromosome number due to fission and fusion have direct and immediate effects on genome structure and recombination rates. These, in turn, may influence ecology and evolutionary trajectories profoundly.

Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3515-3545, December 2022., 2022 Glacial geomorphology and postglacial landforms, derived from LiDAR‐based digital terrain models, together with radiocarbon‐dated sediment sequences, form the basis for landscape reconstruction spanning c. 2000 years (10,500–8500 cal. bp). After formation of streamlined terrain and ribbed moraine tracts followed intense glaciofluvial activity at ...

Perspective: Young Workers at Higher Risk for Carcinogen Exposures
Frontiers in Public Health, 2022 Young workers, those under the age of 25, are considered a vulnerable working population, primarily due to their increased risk of injury. In this study we investigate if young workers may also be at an increased risk for occupational exposure to ...
