Herbivores Enforce Sharp Boundaries Between Terrestrial and Aquatic Ecosystems [PDF]

open access: yes, 2014
The transitions between ecosystems (ecotones) are often biodiversity hotspots, but we know little about the forces that shape them. Today, often sharp boundaries with low diversity are found between terrestrial and aquatic ecosystems.

Role of Lake Aquatic–Terrestrial Ecotones in the Ecological Restoration of Eutrophic Water Bodies

open access: yesToxics, 2023
Freshwater lake eutrophication is a global concern causing adverse effects on aquatic ecosystems. The degradation of lake aquatic–terrestrial ecotones, which are the transitional zones between terrestrial and water ecosystems, contributes to eutrophication.

A predatory waterbird as a vector of plant seeds and aquatic invertebrates [PDF]

open access: yes, 2022
Omnivorous waterbirds play an important role in aquatic ecosystems as dispersal vectors via direct ingestion, transportation, and egestion of plant and invertebrate propagules (i.e. endozoochory).

The oldest semi-aquatic beaver in the world and a new hypothesis for the evolution of locomotion in Castoridae

open access: yesRoyal Society Open Science, 2022
The North American rodent fossil record includes hundreds of species representing both an incredible taxonomic diversity and great ecological disparity. Although it is during the Oligocene that taxonomic diversity first peaks, it is not until the Miocene,

Herbivory on freshwater and marine macrophytes: a review and perspective [PDF]

open access: yes, 2016
Until the 1990s, herbivory on aquatic vascular plants was considered to be of minor importance, and the predominant view was that freshwater and marine macrophytes did not take part in the food web: their primary fate was the detritivorous pathway.

Restoration ecology of aquatic and terrestrial vegetation on non-calcareous sandy soils in The Netherlands* [PDF]

open access: yesActa 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;

Methane formation and consumption by sediments in a cross-channel profile of a small river impoundment

open access: yesJournal of Limnology, 2019
Rivers are a natural source of methane (CH4) into the atmosphere and may contribute significantly to total CH4 emissions. Even though the details of sources of CH4 in rivers are not fully understood, weirs have been recognized as a hotspot of CH4 ...

Aquatic Macrophytes are Seasonally Important Dietary Resources for Moose

open access: yesDiversity, 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 ...

Soil and Freshwater and Marine Sediment Food Webs: Their Structure and Function [PDF]

open access: yes, 2013
The food webs of terrestrial soils and of freshwater and marine sediments depend on adjacent aboveground or pelagic ecosystems for organic matter input that provides nutrients and energy.

More rapid climate change promotes evolutionary rescue through selection for increased dispersal distance

open access: yesEvolutionary Applications, 2013
Species can either adapt to new conditions induced by climate change or shift their range in an attempt to track optimal environmental conditions. During current range shifts, species are simultaneously confronted with a second major anthropogenic ...
