A twofold development and demise of pine stands in the Netherlands during the Allerød interstadial: two hypotheses to explain a link to climate change recorded in Greenland ice

Journal of Quaternary Science, EarlyView.
ABSTRACT The second half of the Allerød interstadial in the Netherlands is characterised by pine forest. Excavated trunks of 165 pine trees at Leusden‐Den Treek in the central Netherlands (LETR16) were dated by dendrochronology and radiocarbon. Two chronologically separated pine forest phases occurred during relatively warm periods as recorded in ...

Feeding strategy and predation of the Barn owl (Tyto alba) and the Burrowing owl (Speotyto cunicularia) on rodent species, sex, and size, in agrosystems of central Argentina

Ecología Austral, 1994
Feeding strategy and predation of the Bartz owl (Tyto alba) and the Burrowing owl (Speotyto cunicularia) on rodent .species, size, and sex was studied by examining consumption and abundance of prey categories in agrosystems of Central Argentina.

Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, EarlyView.
ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...

Does Palsa Thaw in Northern Finland Contribute to Remobilisation of Metals Accumulated in Peat Into Surface Waters?

Land Degradation &Development, EarlyView.
ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Burrowing and Feeding Responses of Different Populations of Sinonovacula constricta to High-Salt Culture Environment

Progress in Fishery Sciences
The razor clam (Sinonovacula constricta, Class Bivalvia) is a kind of burial filter-feeding shellfish. Salinity fluctuation is an important source of pressure for water habitats.

Implications of heterogeneous embankment conditions for geoelectrical investigations on dams: A case study at Mactaquac Dam, Canada

Near Surface Geophysics, EarlyView.
Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines

Oikos, EarlyView.
Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina

Digging in Deep: Size and Site-Specific Variation in Burrow Morphology and Behaviour of the Mud Shrimp, Trypaea australiensis Dana, 1852

Journal of Marine Science and Engineering
The importance of habitats, particularly burrows, for intertidal crustaceans is multifaceted. These habitats provide crucial shelter, food sources, and reproductive advantages that are essential for enhancing survival and fitness.
