Primary productivity in the Gulf of Riga (Baltic Sea) in relation to phytoplankton species and nutrient variability

Oceanologia, 2018
Summary: The seasonal patterns of primary production, phytoplankton biomass, chlorophyll a, and nutrients were investigated in the central part of the Gulf of Riga (Baltic Sea) during 2011 and 2012.

Global radiation in a rare biosphere soil diatom

Nature Communications, 2020
It is generally thought many microbes, owing to their ubiquity and dispersal capability, lack biogeographic structuring and clear speciation patterns compared to macroorganisms. However, Pinseel et al.

Assessing the role of canopy cover on the colonization of phytotelmata by aquatic invertebrates: an experiment with the tank-bromeliad Aechmea lingulata

Journal of Limnology, 2016
The presence of canopy cover may influence the amount of organic detritus and stored water in bromeliad tanks and, consequently, the colonization of these ecosystems by aquatic invertebrates.

Technical note: Fourier approach for estimating the thermal attributes of streams [PDF]

Hydrology and Earth System Sciences, 2016
Temperature models that directly predict ecologically important thermal attributes across spatiotemporal scales are still poorly developed. This study developed an analytical method based on Fourier analysis to estimate seasonal and diel periodicities ...

Potential effects of acanthocephalan and microsporidian parasites on the trophic status of the freshwater isopod Asellus aquaticus

Parasite
Parasites are known for their ability to induce a variety of changes in their respective hosts, including morphological characteristics and trophic interactions. For many host-parasite relationships, however, these aspects are yet to be explored.

Effects of Rising Temperature on the Growth, Stoichiometry, and Palatability of Aquatic Plants

Frontiers in Plant Science, 2019
Global warming is expected to strengthen herbivore-plant interactions leading to enhanced top-down control of plants. However, latitudinal gradients in plant quality as food for herbivores suggest lower palatability at higher temperatures, but the ...

Habitat development and species arrival drive succession of the benthic invertebrate community in restored urban streams

Environmental Sciences Europe, 2023
Background Urban streams are characterised by species-poor and frequently disturbed communities. The recovery of heavily polluted urban streams is challenging but the simple community structure makes recolonisation patterns more transparent.

A predation cost to bold fish in the wild

Scientific Reports, 2017
Studies of predator-mediated selection on behaviour are critical for our understanding of the evolution and maintenance of behavioural diversity in natural populations.

Increases in temperature and freshwater inputs will shift grazing patterns of a coastal mesograzer on foundation species

Ecosphere, 2022
Foundation species, and the roles that they play in structuring ecosystems, are threatened by global change. For example, charophytes are a refuge for zooplankton and stabilize sediments, but they are also a food source for various animal species (water ...

Effects of Dietary Application of the Probiotic Lactobacillus paracasei N1115 on Growth, Hepatic Antioxidant and Immune Biomarkers, and Intestinal Microbiota and Histology of Hybrid Sturgeon (Acipenser baerii ♀ × A. schrenckii ♂)

Aquaculture Nutrition
The objective of this study was to investigate the effects of incorporating Lactobacillus paracasei N1115 (LP N1115) into the diet on growth, hepatic antioxidant and immune biomarkers, and intestinal microbiota and histology of hybrid sturgeon. Fish with
