Anthelmintic resistance in sheep nematodes in Australia: a compilation of recent test results

open access: yesAustralian Veterinary Journal, EarlyView.
Objective The results of recent faecal egg count reduction tests (FECRTs) were collated to provide an indication of the prevalence and severity of anthelmintic resistance in sheep nematodes across Australia and of changes in comparison to earlier testing reports.

Range margins and refugia

open access: yes, 2013
Species ranges are restricted in distribution by physical barriers, dispersal ability, abiotic factors such as climate and interspecific interactions. The responses of a species to environmental conditions and biotic factors determine its abundance, distribution and range limits.

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

open access: yesBoreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

A bifacial paradise—The site of Ochtmissen, Germany, and its lithic assemblage in the context of the last glacial (early MIS 4) in the north‐central European Lowland

open access: yesBoreas, EarlyView.
The Palaeolithic site of Ochtmissen (Lower Saxony, Germany) was excavated in fluvial terrace deposits during the winter of 1993/1994. The current study presents, for the first time, a thorough analysis of the lithic assemblage, encompassing its primary technological and typological characteristics, as well as the type and age of the fluvial deposits ...

A global assessment of animal community responses to agricultural management

open access: yesConservation Biology, EarlyView.
Abstract Transitions in agricultural management through crop and noncrop diversification on intensively managed croplands or pastures have benefited biodiversity. However, the extent to which agricultural management benefits species communities present in undisturbed ecosystems remains largely unclear.

Evaluating the protection status and exposure to warming of Caribbean reefs with high functional potential

open access: yesConservation Biology, EarlyView.
Abstract Over the past decades, climate change has emerged as a major threat to global biodiversity, negatively affecting the integrity and functioning of ecosystems and the benefits they provide to people. To mitigate these impacts, it is essential to identify climate refugia that support the persistence of the structure and function of reef ...

Scientists’ warning on the global destruction of rock outcrop ecosystems

open access: yesConservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...
