Effects of Fiddler Crab Burrows on Sediment Properties in the Mangrove Mudflats of Sungai Sepang, Malaysia

Biology, 2016
In mangrove ecosystems, litter fall accumulates as refractory organic carbon on the sediment surface and creates anoxic sediment layers. Fiddler crabs, through their burrowing activity, translocate oxygen into the anoxic layers and promote aerobic ...

Drought and soil macrofauna functional diversity effects on Mediterranean tree growth in an Ecotron ecosystem experiment

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The intensity, frequency and severity of drought events are projected to increase in the Mediterranean region under ongoing climate change. This may impact plant growth and survival in Mediterranean forests leading to altered ecosystem dynamics. The functional diversity

Einfluß der Bioturbation auf Sedimenttransport in Chile

, 2023
The burial activity of terrestrial bioturbators influences the microtopography, surface roughness, and physical properties of the soil. By reworking sediments, bioturbators increase soil permeability and porosity, which has implications for infiltration ...

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

Journal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.

Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

Journal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.

Use of axial tomography to follow temporal changes of benthic communities in an unstable sedimentary environment (Baie des Ha! Ha!, Saguenay Fjord) [PDF]

, 2003
In the upper layer of the sediment column, organic matter recycling is greatly influenced by bioturbation. However, there are many physical changes in the nature of the sediment that may disturb benthic communities and create a biogeochemical imbalance ...

The Early Upper Palaeolithic in British caves: problems and potential Le Paléolithique supérieur ancien dans les grottes de Grande‐Bretagne : problèmes et potentiels

Journal of the Royal Anthropological Institute, EarlyView.
Recent years have seen landmark progress in our understanding of early Homo sapiens occupation of Europe, owing to new excavations and the application of new analytical methods. Research on British sites, however, continues to lag. This is because of limitations inherent in existing cave collections, and limited options for new fieldwork at known sites.

Combined effects of the landscape and crop management on ant communities

Agricultural and Forest Entomology, EarlyView.
At small spatial scales, agricultural management acts as a stronger ecological filter than landscape context, significantly shaping ant community composition. Species richness and frequency did not differ among treatments, indicating the predominance of generalist species.

Ray bioturbation rates suggest they shape estuary processes

Remote Sensing in Ecology and Conservation
Bioturbation of sediments is a key ecosystem service in estuarine and marine ecosystems, and rays (superorder Batoidea: skates, stingrays, electric rays and shovelnose rays) are among the largest bioturbators, modifying their habitat through foraging and
