Humans are not unique: difficult birth is common in placental mammals
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe
ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

Climate‐induced vegetation greening (NDVImax) stimulated C‐sequestration in subarctic catchments by 10%–85% during the last decades. Increases in weathering and declines in non‐marine SO4 atmospheric deposits were identified as the main drivers of decadal increases in inorganic C (ICalk) run‐off to subarctic lakes.

Horizontal visibility, rather than concealment cover, drove fawn bedsite use and predation risk. Greater field of view decreased the odds of coyote predation, likely by facilitated by early detection. As fawns transitioned from hiders to followers, they shifted from using dense overstory concealment to more open overstory that favored improved escape ...

Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

Abstract The long history of reindeer herding in Fennoscandia has shaped the mountain tundra by influencing its productivity, nutrient and carbon cycling and vegetation structure. By partly limiting shrub expansion, extensive reindeer grazing contributes to ecosystem resilience and helps mitigate climate change effects.

Temporal community change in stream ecosystems varies by assemblage across US climates
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Spatial signatures of group cohesion
Abstract Wildlife populations are undergoing unprecedented changes to their spatial distributions as a result of human activities. Innovative approaches are needed to document these changes, especially in cases where sampling is sparse. Here, we contribute to the tools available in spatial ecology by developing novel metrics based on the coefficient of
