Low flow controls on benthic and hyporheic macroinvertebrate assemblages during supra-seasonal drought [PDF]

, 2009
Despite the widely accepted importance of the hyporheic zone as a habitat for stream macroinvertebrates during floods, few data exist regarding community composition and distribution during periods of low flow or drought in perennial streamsi ...

Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

Wetland microhabitats support distinct communities of aquatic macroinvertebrates

, 2018
The drivers of aquatic macroinvertebrate distribution in Prairie Pothole Region wetlands are not as well understood as in other aquatic ecosystems (e.g. rivers or lakes).

The role of benthic microhabitats in determining the effects of hydromorphological river restoration on macroinvertebrates

Hydrobiologia, 2016
Despite the large number of river restoration projects carried out worldwide, evidence for strong and long-term positive ecological effects of hydromorphological restoration on macroinvertebrates is scarce. To improve the understanding of the success and

Water availability and land‐use shape the diversity of Odonata in the Middle East

Insect Conservation and Diversity, EarlyView.
Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...

Effects of riparian vegetation on water quality and macro invertebrates in the Gilgel Gibe Tributaries, Southwest Ethiopia

Applied Water Science
Riparian vegetation is crucial for both terrestrial and aquatic ecosystems, providing numerous essential benefits. The absence of riparian vegetation along streams can lead to various pressures that negatively affect macroinvertebrates and their habitats.

Macroinvertebrates, Heavy Metals and PAHs in Urban Watercourses [PDF]

, 2001
Good quality stream water and sediments are crucial for the support of healthy stream flora and fauna but urban runoff degrades watercourses leaving a legacy of pollution in the stream sediments.

Ontogeny of escape response and body shape in threespine stickleback (Gasterosteus aculeatus L.)

Journal of Fish Biology, EarlyView.
Abstract Escape responses in fishes provide insight into accelerative motions and behavioural response times of these animals, linking numerous fitness‐related traits. We sought to connect escape response performance to genotype and phenotype across ontogenetic stages within a single population of threespine stickleback (Gasterosteus aculeatus L.) to ...

Benthic Macroinvertebrates Composition, Diversity and Distribution of Daberam Reservoir, Katsina State, Nigeria

UMYU Journal of Microbiology Research
Macrobenthic invertebrates are significantly considered to be bioindicators by providing a key concept in understanding the dynamics in aquatic conditions rather than chemical and microbiological data, which at least give short-term fluctuations. Recent
