Revealing the influence of hyporheic water exchange on the composition and abundance of bottom-dwelling macroinvertebrates in a temperate lowland river

open access: yesKnowledge and Management of Aquatic Ecosystems, 2021
We studied distributions and abundances of macroinvertebrates in relation to hyporheic water exchange (HWE) patterns of the upper Biebrza − a small, lowland, low dynamic European river located in Northeast Poland.

Environmental assessments for seabed impact and resilience from aquaculture: a case study in an intensive production area (Frøya, Norway)

open access: yesFrontiers in Marine Science
Norway mandates protocols to manage salmon aquaculture’s impact on the seabed, with B-assessments for directly beneath the cages and C-assessments for the broader surrounding seabed with more chemical and biological variables. This study aimed to utilize

Habitat change driven by plant invasion restructures benthic diversity in intertidal wetlands

open access: yesGlobal Ecology and Conservation
Since its introduction to China in 1979, Spartina alterniflora has steadily expanded along the southeast coast of China and reshaped the intertidal ecosystem by altering the properties of sediments. These changes, in turn, will affect the composition and

Profundal benthic invertebrates in an oligotrophic tropical lake: different strategies for coping with anoxia

open access: yesJournal of Limnology, 2014
The deep benthic communities of tropical lakes are poorly understood with respect to their composition, abundance, biomass and regulatory factors. Whereas the hypolimnia of temperate oligotrophic lakes remain oxygenated, the higher temperatures in ...

Diversity of zooplankton and benthic macroinvertebrates of estuarine coastal waters in Tien Giang province, southern Vietnam

open access: yesVietnam Journal of Science, Technology and Engineering, 2022
The Tien Giang province is located in the tropical climate zone of the Mekong delta. In this study, the diversity of zooplankton and benthic macroinvertebrates were investigated in the estuarine coastal waters of the Tien Giang province of southern ...

Vertical Distribution of Particulate Matter in the Clarion Clipperton Zone (German Sector)—Potential Impacts From Deep-Sea Mining Discharge in the Water Column

open access: yesFrontiers in Marine Science, 2022
Most studies on the potential impacts of deep-sea mining in the Clarion Clipperton Zone (CCZ) have largely focused on benthic ecosystems but ignore the pelagic environment. To model full-scale impacts, it is important to understand how sediment discharge

Planktonic and benthic foraminiferal biostratigraphy of the Middle Eocene–Lower Miocene successions from the Sivas Basin (Central Anatolia, Turkey)

open access: yesGeologica Carpathica, 2016
Planktonic and benthic foraminifera are described from the Middle Eocene-Lower Miocene successions in the Sivas Basin, Central Anatolia. An integrated foraminiferal zonation provides new age assignments in terms of a great number of taxa for the studied ...

Severity gradient of anthropogenic activities along the Egyptian Western Mediterranean coast, utilizing benthic Foraminifera as bio-indicators

open access: yesEgyptian Journal of Aquatic Research, 2022
Three locations along the western Mediterranean coastal zone of Egypt (Abu Qir Bay, El Max Bay, and Marsa Matrouh), have been exposed to different anthropogenic sources that threatened the benthic ecosystem conditions.

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

open access: yesThe Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...
