Numerous studies have shown that during the Quaternary there were substantial fluctuations in sea level in response to glacial–interglacial climate variability, reaching lowstand positions up to 134 m below the present sea level (b.s.l.). These fluctuations have had a strong influence on the morphology of shallow shelf seas, which preserve evidence of ...

Lodge moraines: a common yet underreported end‐moraine type—a review
Lodge moraines are a distinct genetic type of end moraine formed by submarginal accretion of subglacial till; they are some of the largest end moraines in the world. Although underreported in the literature, they are of equal importance to push, dump and hummocky end moraines. End moraines are formed at glacier ice margins and show the extent of former

Truncated drumlins and their implication for past sea level reconstructions
Coastal erosion of glacigenic sediments, particularly in the form of retreating drumlin bluffs, is a key process in paraglacial landscape evolution during periods of relative sea‐level (RSL) rise. As marine transgression reworks formerly subaerial glacial terrains, drumlins act as discrete sediment sources generating characteristic erosional and ...

Prioritizing site groups for intrinsic biodiversity assets using complementarity and not just rarity
Conservation practitioners rightfully focus on at‐risk species when valuing biodiversity assets and prioritizing spatial units. We compared and combined numbers of at‐risk species with four other community metrics using surveys of vascular plants at wetlands in a preserve network in Illinois, USA.

Repeated Introductions and Anthropogenic Dispersal Fuel the Regional Expansion of Ambrosia trifida
ABSTRACT Understanding the processes that shape biological invasions is essential for predicting the spread and persistence of introduced species, yet these processes remain poorly resolved for many unintentionally introduced plants. We combined genome‐wide SNP data, demographic modeling, and climatic niche analyses to investigate the invasion of giant

ABSTRACT Aim The Neotropical region is the most biodiverse in the world, and several hypotheses have been proposed to explain this pattern. Among them, the most prominent are the hypotheses of biotic interchange between domains, climatic refugia during the Pleistocene and geomorphological changes during the Miocene, such as the reorganization of the ...
