Hydrological Connectivity and Local Environment Alternately Drive Spatial Structure of Floodplain Aquatic Community Across Seasons. [PDF]
Ecol EvolOur study shows that the landscape‐scale environmental gradient represented as ecotone and as local environmental factors can alternately determine the spatial structures of the floodplain biota across seasons. The study highlights the understudied yet important linkages of spatial and temporal biotic assemblages and advance understanding of ecology ...

Multi-Decadal Trends in Northern Lakes Show Contrasting Responses of Phytoplankton and Benthic Macroinvertebrates to Climate Change. [PDF]
Glob Chang BiolNorthern lakes are changing due to climate warming and landscape alterations. Three decades of time‐series data for 110 Swedish lakes showed that phytoplankton and bottom‐dwelling littoral and profundal faunal assemblages are responding to these environmental changes. Yet, the responses differed among the three organism groups.

Journal of Limnology, 2008 Daphnia and Bosmina fragments were identified and measured in the surface sediments of 42 lakes in the Muskoka-Haliburton region of Ontario, Canada, in an attempt to identify environmental factors that may influence cladoceran body size.

Energetics of Vertical Migration in Chaoborus Trivittatus Larvae [PDF]
Ecology, 1976 One of the recent theories for the adaptive value of vertical migration states that migrants gain an energetic advantage over nonmigrants because by alternating between areas of high and low temperatures they are able to partition energy into growth more efficiently than nonmigrants.

Stable isotope patterns in lake food webs reflect productivity gradients
Ecosphere, 2020 Stable isotopes 13C and 15N are often used in lake ecosystems to assess energy sources and trophic positions, respectively. However, δ13C and δ15N are also influenced by internal biogeochemical processes in epilimnetic and hypolimnetic habitats in lakes,

Gene up-regulation in response to predator kairomones in the water flea, Daphnia pulex [PDF]
, 2010 Background: Numerous cases of predator-induced polyphenisms, in which alternate phenotypes are produced in response to extrinsic stimuli, have been reported in aquatic taxa to date.

Effects of the pyrethroid insecticide gamma-cyhalothrin on aquatic invertebrates in laboratory and outdoor microcosm tests [PDF]
The sensitivity of a range of freshwater lentic invertebrates to gamma-cyhalothrin (GCH), a single enantiomer of the synthetic pyrethroid lambda-cyhalothrin, was assessed in single species laboratory tests and an outdoor multi-species ecosystem test. The

Arctic, Antarctic, and Alpine Research, 2020 Climate change and associated permafrost thaw are creating new shallow waterbodies in vast regions of the circumpolar Arctic. These thaw ponds are characterized by high concentrations of colored dissolved organic matter originating from the degrading ...
