Measuring Complexity in an Aquatic Ecosystem
, 2013 We apply formal measures of emergence, self-organization, homeostasis, autopoiesis and complexity to an aquatic ecosystem; in particular to the physiochemical component of an Arctic lake. These measures are based on information theory.

Efficient sampling methodologies for lake littoral invertebrates in compliance with the European Water Framework Directive [PDF]
, 2015 Lake shores are characterised by a high natural variability, which is increasingly threatened by a multitude of anthropogenic disturbances including morphological alterations to the littoral zone. The European Water Framework Directive (EU WFD) calls for

An enigmatic Maastrichtian small benthic Foraminifera of the Tarbur Formation (Iran, Zagros zone)
Cretaceous Research, 2020 The Maastrichtian carbonates of the Tarbur Formation from the Zagros zone (SW Iran) are very rich in larger Foraminifera. Additionally, smaller benthic Foraminifera occur as well, one of them presented here as Zagrosaria pinnata gen. et sp. nov. It occurs abundantly at the Mandegan section within two levels corresponding to the lower photic zone. Based

The effects of a benthic grazer on the primary productivity of the littoral zone of Lake Tahoe1 [PDF]
Limnology and Oceanography, 1975 A large population of crayfish (Pacifastacus leniusculus) inhabits the littoral zone of Lake Tahoe. The effect of crayfish grazing on the primary productivity of the periphyton was investigated in field and laboratory enclosures by varying the ratio of crayfish to substrate. In the field, primary productivity was enhanced after 66 days in a low density

Journal of Quaternary Science, EarlyView.ABSTRACT Water bodies located in floodplains and tropical forests are known to be important carbon stores, but many are subjected to intensive pressures from damming, land use and climate changes. Sedimentary records preserve long‐term archives for understanding how such changes affect the quantity and quality of carbon stores.

The impact of significant input of fine sediment on benthic fauna at tributary junctions: a case study of the Bermejo-Paraguay River confluence, Argentina [PDF]
, 2014 This study examines the morphological features, suspended sediment inputs and hydraulic conditions within a large river in association with ecological patterns before and after a tributary confluence.

Geologica Acta, 2020 A taxonomic study of the larger foraminifera found in Paleocene rocks from the Pyrenean basin has led to the description of sixty taxa including two new species: Alveolina korresensis and Valvulineria bacetai. In this work, we present a chronostratigraphic recalibration of the Paleocene Shallow Benthic Zones (SBZ 1 to SBZ 4) based on correlation with ...

Benthic inputs as predictors of seagrass (Posidonia oceanica) fish farm-induced decline [PDF]
arXiv, 2006 Fish farms represent a growing source of disturbance to shallow benthic ecosystems like seagrass meadows. Despite some existing insights on the mechanisms underlying decline, efficient tools to quantitatively predict the response of benthic communities to fish farm effluents have not yet been developed.
