Abstract:
... Water impoundment is among the most prevalent and potent forms of anthropogenic environmental modification worldwide. Flow modification can drive morphological changes in riverine species that persist after dam closure, but little is known about the tempo and trajectory of phenotypic responses to impoundment. Through geometric morphometric analysis of natural history collections from behind Claibo ...

Abstract:
... Temporary lentic water bodies host biotic assemblages adapted to the transient nature of these freshwater habitats. Fairy shrimps (Crustacea, Branchiopoda, Anostraca) are one of the most important biological components of these unique environments and have a fossil record dating back to the Middle Jurassic (>150 million years). Some anostracan species show a geographically restricted distribution, ...

Chironomidae; Eucalyptus marginata; Mediterranean climate; Plecoptera; Trichoptera; climate change; ecosystems; leaf mass; leaves; limnology; macroinvertebrates; plant litter; water; weight loss; Australia
Abstract:
... Climate change is altering hydrologic regimes globally. In the Mediterranean climate region of south‐western Australia (SWA), climate drying has caused many perennial streams to switch to intermittent flow regimes. Shifts in flow regime are expected to alter physical and biological processes in streams, including litter decomposition, which is the basis of detrital food webs. Decomposition of jarr ...

Cyprinus carpio; acoustics; fish; fish ladders; group size; invasive species; limnology; phylogeny; turbidity; water temperature; wetlands; Ontario
Abstract:
... Non‐structural deterrents may limit invasive fish dispersal and range expansion without altering waterflow or navigation. Despite extensive research in laboratory and artificial environments, few studies have been conducted in situ and, of those, few have evaluated the full community response of fishes interacting with the deterrent. We deployed acoustic deterrents within a physical trap‐and‐sort ...

Abstract:
... Freshwater cyanobacterial blooms have become ubiquitous, posing major threats to ecological and public health. Decades of research have focused on understanding drivers of these blooms with a primary focus on eutrophic systems; however, cyanobacterial blooms also occur in oligotrophic systems, but have received far less attention, resulting in a gap in our understanding of cyanobacterial blooms ov ...

Abstract:
... A pregnancy imposes a heavy reproductive burden on females. Some live‐bearing species have evolved reproductive adaptations to reduce this burden, which may influence their ability to use specific microhabitats. We investigate whether two such reproductive adaptations, placentation (embryo provisioning via a placenta) and superfetation (the ability to carry multiple broods at various developmental ...

Abstract:
... Exotic poeciliids have been reported to reduce abundance and richness of native fishes and, more generally, constrain the trophic niches of native counterparts. However, understanding of the consequences of poeciliids on native fishes in tropical streams is limited. We conducted a survey of lowland streams in Hong Kong during 2018–19 to document the prevalence of poeciliids and look for signs that ...

Abstract:
... Fish larval drift is an essential step in the life cycle of riverine fish species as it determines dispersal and colonisation. Anthropogenic flow alterations and interruption of longitudinal and lateral connectivity by river damming and straightening can severely affect larval drift patterns. In this study, we characterised spatio‐temporal drift patterns of fish larvae in the heavily regulated lar ...

Abstract:
... Metacommunity ecology includes connectivity in the investigation of local and regional processes to understand community assembly. The elements of metacommunity structure (EMS) framework classifies metacommunities into categorical archetypes based on patterns of three metrics indexing β diversity: coherence, turnover, and boundary clumping. Although the EMS framework is most commonly used to class ...

Abstract:
... Knowledge on the ecological determinants and evolutionary processes shaping intraspecific variability in the wild remains scarce. It is particularly needed in the context of biological invasions to fully understand the consequences of invasive species on the functioning of recipient ecosystems. Using geometric morphometrics, stable isotopes, and elemental composition analyses, we quantified phenot ...

benthic zone; biomass; bioturbation; carbon; carbon dioxide; community structure; greenhouse gases; limnology; macroinvertebrates; methane; oxidation; oxygen; pelagic fish; predation; sediments; zooplankton
Abstract:
... Shallow aquatic systems exchange large amounts of carbon dioxide (CO₂) and methane (CH₄) with the atmosphere. The production and consumption of both gases is determined by the interplay between abiotic (such as oxygen availability) and biotic (such as community structure and trophic interactions) factors. Fish communities play a key role in driving carbon fluxes in benthic and pelagic habitats. Pr ...

Abstract:
... Conservation management of freshwater ecosystems often focuses on mitigating or reversing the negative effects of altered patterns of river discharge. Assessments of management interventions frequently focus on direct, short‐term responses to discharge without consideration of underlying population trends that span multiple years. We sought to determine the effects on fish populations of annual va ...

Unionoida; freshwater; freshwater mussels; habitats; hydrodynamics; limnology; riparian areas; sedentary species; sediment-water interface; shear stress; species richness; streams; water management
Abstract:
... Riverine species are governed by the physical (i.e. hydrodynamic) forces generated by flowing water. Freshwater species are also disproportionately imperilled compared to terrestrial and marine species in large part due to widespread anthropogenic alteration of the natural flow regimes to which organisms are adapted. Sedentary species such as freshwater mussels (Bivalvia: Unionoida) are especially ...
