Ecosystem roles and conservation status of bioturbator mammals
(2022-04-01)
The action of biological reworking of soils is referred to as bioturbation, and many species of mammals globally have an important role in soil disturbance, modifying ecosystem characteristics. We examined global patterns ...
Effect of crab bioturbation on organicmatter processing in SouthWest Atlantic intertidal sediments
(Elsevier Science, 2014-06-05)
Organic matter (OM) remineralization plays a key role in controlling the biogeochemistry of marine sediments. Through their burrowing activities, bioturbating macrofauna not only induces physical, chemical and biological ...
Bioturbation 1 enhances C and N contents on near-surface 2 soils in resource-deficient arid climate regions but shows 3 adverse effects in more temperate climates
Bioturbating animals can affect physical and chemical soil properties on near-surface soil by either foraging for food or constructing suitable habitats. Thereby, bioturbation can influence the soil texture either sorting ...
Regenerative bioturbation by intertidal burrowing crabs modifies microphytobenthic composition and enhances primary production in SW Atlantic mudflats
(Inter-Research, 2019-12)
In coastal systems, benthic microalgae are important primary producers that significantly contribute to global primary production. Microphytobenthic (MPB) community structure and the ecosystem functions that it mediates ...
Vegetation and vertebrate abundance as drivers of bioturbation patterns along a climate gradient
(Public Library of Science, 2022)
© 2022 Public Library of Science. All rights reserved.Bioturbators shape their environment with considerable consequences for ecosystem processes. However, both the composition and the impact of bioturbator communities may ...
Effects of two estuarine intertidal polychaetes on infaunal assemblages and organic matter under contrasting crab bioturbation activity
(Elsevier Science, 2018-09)
Polychaetes and burrowing crabs are widely distributed in intertidal soft bottom environments, playing an important role in structuring infaunal assemblages through trophic and non-trophic interactions such as bioturbation. ...
Potential effect of fiddler crabs on organic matter distribution: A combined laboratory and field experimental approach
(2017-01-05)
Bioturbators play a key role in estuarine environments by modifying the availability of soil elements, which in turn may affect other organisms. Despite the importance of bioturbators, few studies have combined both field ...
Crab bioturbation and herbivory reduce pre- and post-germination success of Sarcocornia perennis in bare patches of SW Atlantic salt marshes
(Inter-Research, 2010-01)
Colonization of bare patches is a key process during community development given that pioneers usually have positive and negative effects on the forthcoming species. A variety of biotic and abiotic factors influence the ...
Biogenic reworking patterns in highly bioturbated shallow-marine transgressive successions (Jurassic, Neuquén Basin, Argentina)
(International Association of Sedimentology, 2019)
Thick (10s of m) successions of highly bioturbated, storm-influenced shallow-marine deposits are relatively uncommon in the rock record. Some examples have been reported from retrogradational successions associated with ...
Burrow morphology of Uca uruguayensis and Uca leptodactylus (Decapoda: Ocypodidae) from a subtropical mangrove forest in the western Atlantic
(Wiley-Blackwell, 2013-09-01)
The continuous excavation of burrows by fiddler crabs generates bioturbation in the sediment, which can be estimated from burrow morphology. The aim of the present study was to describe the burrow morphology of Uca ...
