Debris at the edge: sedimentological dynamics of Hintereisferner's evolving terminus and glacial forefield, Austrian Alps

open access: yesBoreas, EarlyView.
The interaction between glaciers and the debris accumulating on their surfaces is critical as the Earth warms, with consequences for ice dynamics, hydrology and mass balance together with slope and sedimentary processes. Understanding this interaction is necessary since it influences ablation rates, sediment and meltwater pathways.

Extreme weather and economic crisis in the 1430s in England, and the implications for tenurial change

open access: yesThe Economic History Review, EarlyView.
Abstract The 1430s were characterized by extreme weather conditions, food and fodder shortages, and high mortalities among animals and humans, although the severity of events and their consequences in England have received limited attention. The economic downturn and the depressed customary land market in this decade marked the beginning of the Great ...

Harsh environmental conditions promote cooperative behavior in an epiphytic fern

open access: yesPlant Signaling & Behavior
Harsh, unpredictable environments are known to favor cooperative groups in animals. Whether plants exhibit similar relationships is unknown. Staghorn ferns (Platycerium bifurcatum, Polypodiaceae) are epiphytes that form cooperative groups which build ...

Speciation of European bullheads (Cottus spp.): The next problem for taxonomy of northern freshwater fishes

open access: yesJournal of Fish Biology, EarlyView.
Abstract High morphological and ecological diversity displayed by European bullheads led Freyhof et al. (2005) to describe 15 nominal species. However, the basis for declaring these nominal species is contentious due to a lack of rigorous statistical analysis of morphological variations among populations, limitations in the inferences made from ...

Convergence and parallelism in the evolution of plant metabolism

open access: yesJournal of Integrative Plant Biology, EarlyView.
Similar traits in different organisms may originate from shared ancestry or evolve independently. The terminology used to define phenotypic similarity is often confusing. This review attempts to clarify the definitions and present examples from plant domestication and specialized metabolism to explain how complex traits evolve repeatedly in plants ...
