Science of The Total Environment, 2022 Anthropogenic climate change and landscape alteration are two of the most important threats to the terrestrial and aquatic ecosystems of the tropical Americas, thus jeopardizing water and soil resources for millions of people in the Andean nations. Understanding how aquatic ecosystems will respond to anthropogenic stressors and accelerated warming ...

Aquatic Macrophytes are Seasonally Important Dietary Resources for Moose
Diversity, 2019 Moose (Alces alces) are generalist herbivores, but are important aquatic-terrestrial ecotone specialists. Aquatic macrophytes are a high-quality food source for moose during summer, but the importance of aquatic food sources to the moose diet is ...

Tracking diet preferences of bats using stable isotope and fatty acid signatures of faeces. [PDF]
PLoS ONE, 2013 Stable isotope and fatty acid signatures of biomaterials can provide important information about the dietary niche of animals. Stable isotope and fatty acid signatures differ between aquatic and terrestrial food webs, and therefore can be used to assess ...

DNA metabarcoding in diet studies: Unveiling ecological aspects in aquatic and terrestrial ecosystems [PDF]
Environmental DNA, 2019 AbstractEffective conservation of species and ecosystems requires the understanding of important ecological traits, such as dietary habits, food webs, and trophic niches. In diet studies, the visual identification of partially digested prey has been enhanced with the recent more powerful and accurate technique, DNA barcoding.

Restoration ecology of aquatic and terrestrial vegetation on non-calcareous sandy soils in The Netherlands* [PDF]
Acta Botanica Neerlandica, 1996 Plant and animal diversity of the Dutch landscape is mostly restricted to (semi-)natural ecosystems in nature reserves. Many of these plant and animal species are at this moment seriously threatened by environmental stresses, such as air pollution, eutrophication, desiccation or lowering of the water table and habitat fragmentation (e.g. Westhoff 1979;
