Patterns and mechanisms of repeat drainages of glacier-dammed Dań Zhùr (Donjek) Lake, Yukon

open access: yesArctic Science
Dań Zhùr (Donjek) Glacier is a surge-type glacier that undergoes cyclical periods of rapid advance over ∼1–2 years, followed by retreat for ∼10 years. Since the 1990s, the advances have caused the formation of ice-dammed Dań Zhùr Lake, which has filled ...

Pest‐preservation paradox among insects

open access: yesConservation Biology, EarlyView.
The pest‐preservation paradox is a non‐binary perspective that insects range from those that are harmful and requiring management on the one side, to those requiring conservation intervention on the opposite end of the spectrum. Importantly, the vast majority of insects occur somewhere in the center of the two extremes, and their position along the ...

Producing a Red List of Ecosystems for the Brazilian Cerrado

open access: yesConservation Science and Practice, EarlyView.
Land clearance is a key driver of biodiversity loss. This is a particular issue in the Brazilian Cerrado, the world's most biodiverse savanna biome and a region experiencing the rapid expansion of agriculture. By using the Red List of Ecosystems as an international standard, we provide the first globally comparable analysis of the state of the Cerrado,

A rapid shift in migration schedule of an Austral shorebird is linked to a changing southern climate oscillation

open access: yesIbis, EarlyView.
Global climate change is reshaping the schedules and routes of migratory birds, which can disrupt annual cycles, ecological interactions and the fitness trade‐offs of migrating or staying resident. In particular, climate change has led to advances in arrival at the breeding grounds and to shifts in the timing of post‐breeding migration, whereby both ...

Legacies and Ruptures: Europe's Future in a New (?) Era of Geopolitical Uncertainty

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract Europe finds itself adrift in a world of rising geopolitical uncertainty. Russia has brought interstate war back to Europe. American democracy and hegemony and the ‘liberal international order’ appear to be in steep decline. The world as Europeans and Americans have known it for 80 years may be gone forever.

Circumscription of three new taxa of Merismopedia‐like Cyanobacteria shows how far convergent evolution can go

open access: yesJournal of Phycology, EarlyView.
Abstract The genus Merismopedia (Merismopediaceae, Chroococcales), characterized by rectangular colonies with cells arranged in regular perpendicular rows and columns, represents a challenging study system due to its limited cultivability. The genus recently underwent taxonomic revision using cultivation‐independent techniques and a polyphasic approach.

Glacier elevation and mass changes over the central Karakoram region estimated from TanDEM-X and SRTM/X-SAR digital elevation models

open access: yesAnnals of Glaciology, 2016
Snow cover and glaciers in the Karakoram region are important freshwater resources for many down-river communities as they provide water for irrigation and hydropower.

Influence of menstrual cycle phase on inflammatory and vascular responses to acute passive heating in healthy young women

open access: yesExperimental Physiology, EarlyView.
Abstract The aim of this study was to determine whether inflammatory and vascular responses to passive heating differ between the early follicular phase (EFP) and the mid‐luteal phase (MLP) of the menstrual cycle. Ten healthy, naturally menstruating females (26 ± 3 years of age; body mass index 21.4 ± 1.9 kg/m2) were assessed during EFP and MLP ...
