Hotter, faster, sicker? Warming shifts the cost of infection from individuals to populations

Journal of Animal Ecology, EarlyView.
This study examines how temperature alters disease impacts across biological scales in a host–pathogen system. We found infected hosts appear healthiest at warm temperatures, yet populations suffer most. This suggests climate warming may intensify disease impacts for populations in ways traditional individual‐level virulence metrics fail to predict ...

Varying degradation of subfossil Daphnia longispina during the past 250 years and the discovery of fossil helmet-type head shields: preliminary results

Advances in Oceanography and Limnology, 2016
Zooplankton are regarded as a good indicator of environmental change, but comprehensive monitoring programs including  zooplankton are uncommon and only rarely extend over longer periods of time.

Mycosporine-Like Amino Acids (MAAs) in Zooplankton

Marine Drugs, 2020
Organisms have different adaptations to avoid damage from ultraviolet radiation and one such adaptation is the accumulation of mycosporine-like amino acids (MAAs).

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.

Diet of juvenile skipjack herring Alosa chrysochloris: Ontogenetic shifts, predator–prey size ratios and mouth gape allometry

Journal of Fish Biology, EarlyView.
Abstract The skipjack herring Alosa chrysochloris inhabits Gulf of Mexico drainages, primarily the Mississippi River Basin, and estuarine environments in the Gulf of Mexico. The trophic ecology of the skipjack herring is poorly understood, therefore we quantified the length, mouth gape and gut contents of juvenile skipjack herring from the Mississippi ...

Cladocera species composition in lakes in the area of the Hornsund Fjord (Southern Spitsbergen) – preliminary results

Knowledge and Management of Aquatic Ecosystems, 2011
Species composition of benthic and planktonic Cladocera was analysed in four lakes and ponds located in the southern part of the Spitsbergen Island near the Fjord Hornsund.

Multitrophic responses to tidal marsh restoration: early effects of channel configuration on water quality, aquatic food web structure, and fish communities

Restoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is critical for reversing habitat loss and enhancing resilience under sea‐level rise and climate variability. Dutch Slough in the San Francisco Estuary served as a living laboratory for adaptive management.

Decadal Rapid Change in Energetic Carrying Capacity for Juvenile Chum Salmon in the Sanriku Coast

Fisheries Oceanography, Volume 35, Issue 4, Page 545-564, July 2026.
ABSTRACT Adult returns to coastal rivers in Sanriku, located near the southernmost area of chum salmon distribution, have declined since 2010. Climate‐induced fluctuations in juvenile prey availability may affect growth and survival, which are linked to adult returns.

Zooplankton community responses to the mixture of imazethapyr with imazapic and bispyribac-sodium herbicides under rice paddy water conditions

Ciência Rural, 2014
The aim of this study was to assess the effect of concentrations of imazethapyr, imazapic, and bispyribac-sodium herbicides on zooplankton community (Cladocer, Copepod and Rotifer) in rice paddy fields. The decrease of half-life dissipation (DT50) of the

Benthic Microalgae Respond More Strongly to Warming and Salinity Than Zooplankton

Ecology and Evolution, Volume 16, Issue 6, June 2026.
The effects of multiple simultaneous stressors on different trophic levels are poorly known. Warming changed the composition of both benthic diatom and zooplankton communities, but the interaction of warming and decreasing salinity affected only benthic diatoms. ABSTRACT The effects of elevated temperature are pronounced in high latitudes where warming
