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

Boreas, 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.

The Influence of Abiotic Factors on the Distribution of Macrophytes in Small Water Bodies in Temperate Ecosystems

Limnological Review
Currently, reviews focusing on the distribution of macrophytes focus primarily on large water bodies, regardless of the fact that small water bodies (SWBs), such as ponds, ditches and streams, often support higher levels of gamma macrophyte richness ...

Macrophyte assessment in European lakes: Diverse approaches but convergent views of 'good' ecological status [PDF]

, 2018
The European Water Framework Directive has been adopted by Member States to assess and manage the ecological integrity of surface waters. Specific challenges include harmonizing diverse assessment systems across Europe, linking ecological assessment to ...

Ecological variability of Hippopotamus antiquus from the late Early–Middle Pleistocene of Megalopolis Basin (Greece): Evidence for dynamic habitats in a glacial microrefugium

Boreas, EarlyView.
This study investigates the ecology of the extinct European Hippopotamus from the late Early–Middle Pleistocene (c. 900–400 ka) sequence of the Megalopolis Basin, a glacial microrefugium for temperate taxa in southern Greece. Using stable carbon (δ13C) and oxygen (δ18O) isotope analyses and microwear analyses of Hippopotamus dental elements, we ...

Testing the performance of the Macrophyte Index for Rivers and the Riverine Macrophyte Nutrient Index in a river reach subjected to multiple stressors in NE Bulgaria

Acta Biologica Slovenica
The objective of this study was to evaluate the performance of two macrophyte-based indices, the Macrophyte Index for Rivers (MIR) and the Riverine Macrophyte Nutrient Index (RMNI), in a heavily modified river reach exposed to multiple stressors in ...

A simple, robust, and inexpensive design for creating thermal refugia to protect amphibians from Batrachochytrium dendrobatidis in the field

Conservation Science and Practice, EarlyView.
Abstract The emergence and spread of wildlife diseases requires innovative, practical solutions to help vulnerable species survive in the wild. One promising approach involves exploiting mismatches in environmental tolerances between pathogens and their hosts to reduce disease impacts.

Capture Probability and Effects of Bait Type on Learning Behavior in an Unexploited Population of Northern Pike (Esox lucius)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Changes in angling response were studied over a period of three years in a natural, previously unfished population of northern pike. Standardized angling sessions took place during two weeks in spring and autumn with three bait types: bright‐ and natural‐colored soft plastic baits and a dead baitfish.

Go hard or go home: Major removal of woody vegetation and sediment greatly enhances wetland plant and water beetle diversity recovery in a farmland pond landscape

Ecological Solutions and Evidence
Ponds are important habitats for biodiversity conservation and ecosystem service provisions in farmland settings. Agricultural intensification and cessation of traditional management have resulted in a substantial loss of open‐canopy farmland ponds ...
