Fish community composition in small lakes: The impact of lake genesis and fisheries management.

Publication Type: Academic Journal

Source(s): Freshwater Biology. Dec2022, Vol. 67 Issue 12, p2130-2147. 18p.

Abstract: Gravel pit lakes are common across Europe. These novel ecosystems serve as model systems to study human‐induced and natural colonisation of isolated lakes by fish. Fisheries‐management activities can quickly spread species over large distances, possibl...

The Key Environmental Factors Shaping Coastal Fish Community in the Eastern Gulf of Finland, Baltic Sea.

Publication Type: Academic Journal

Source(s): Diversity (14242818). Nov2022, Vol. 14 Issue 11, p930. 20p.

Abstract: A highly productive coastal zone plays an important role in various stages of fish life cycles, e.g., spawning migrations, fish reproduction, larval development, juveniles growing, etc. Therefore, coastal biotopes significantly contribute to commercial...

Environmental nucleic acids: A field‐based comparison for monitoring freshwater habitats using eDNA and eRNA.

Publication Type: Academic Journal

Source(s): Molecular Ecology Resources. Nov2022, Vol. 22 Issue 8, p2928-2940. 13p.

Abstract: Nucleic acids released by organisms and isolated from environmental substrates are increasingly being used for molecular biomonitoring. While environmental DNA (eDNA) has received much attention, the potential of environmental RNA as a biomonitoring to...

Bacterial communities in co-cultured fish intestines and rice field soil irrigated with aquaculture wastewater.

Publication Type: Academic Journal

Source(s): AMB Express. 10/22/2022, Vol. 12 Issue 1, p1-10. 10p.

Abstract: In some regions, integrated rice-fish farms have been developed to balance the needs of aquaculture wastewater discharge and rice field irrigation. In this type of aqua-agriculture system, soil is irrigated with aquaculture wastewater, and intestinal b...

Barrier removal and dynamics of intermittent stream habitat regulate persistence and structure of fish community.

Publication Type: Academic Journal

Source(s): Scientific Reports. 10/22/2022, Vol. 12 Issue 1, p1-14. 14p.

Abstract: Barrier effects observed in the presence of weirs are exacerbated by low water levels. We conducted a 10-year study to assess the ecological effects of stream restoration while analysing the possibility of a seasonal lack of hydrological continuity, wi...

Shifts in fish community composition and structure linked to seasonality in a tropical river.

Publication Type: Academic Journal

Source(s): Freshwater Biology. Oct2022, Vol. 67 Issue 10, p1789-1800. 12p.

Abstract: The seasonality of tropical rivers, induced mainly by water level changes, shapes many interrelated aspects of ecological communities and the populations they contain, including animal movement, feeding, growth, and reproductive activity. However, the ...

Reproduction influences seasonal eDNA variation in a temperate marine fish community.

Publication Type: Academic Journal

Source(s): Limnology & Oceanography Letters. Oct2022, Vol. 7 Issue 5, p443-449. 7p.

Abstract: Many factors influence how environmental DNA (eDNA) abundance varies in natural environments. One of the least studied contributors to eDNA variation is that of reproduction. Marine organisms that broadcast spawn are expected to shed increased quantiti...

Large fish forage lower in the food web and food webs are more truncated in warmer climates.

Publication Type: Academic Journal

Source(s): Hydrobiologia. Oct2022, Vol. 849 Issue 17/18, p3877-3888. 12p. 1 Diagram, 3 Charts, 3 Graphs.

Abstract: Body size is usually considered a good indicator of trophic position in fish communities. Indeed, the proverbial wisdom that "Big Fish Eat Little Fish" is consistent with observations from marine systems where systematic removal of the largest individu...

Characterization of Fish Assemblages and Standard Length Distributions among Different Sampling Gears Using an Artificial Neural Network.

Publication Type: Academic Journal

Source(s): Fishes (MDPI AG). Oct2022, Vol. 7 Issue 5, p275-N.PAG. 11p.

Abstract: Several sampling gears are used to collect fish in the lentic ecosystem. The collected fish differ in their characteristics and community structure depending on the sampling gear. The objectives of this study were to 1) compare the community structure ...

Recent warming causes functional borealization and diversity loss in deep fish communities east of Greenland.

Publication Type: Academic Journal

Source(s): Diversity & Distributions. Oct2022, Vol. 28 Issue 10, p2071-2083. 13p. 1 Color Photograph, 1 Diagram, 2 Graphs.

Abstract: Aim: We assessed temporal trends in functional diversity of the deep‐sea demersal fish communities of East Greenland to characterize ecological responses to rising sea temperatures. Location: The study region encompasses a shelf and slope area located ...
