Changes in the Size Distribution of a Freshwater Fish After Lake Outlet Dam Removal: A Pilot Study

open access: yesEcohydrology, Volume 18, Issue 5, July‐August 2025.
ABSTRACT The size structure of populations is crucial for predator–prey dynamics and ecosystem function. Anthropogenic pressures such as habitat alteration may affect the demography of many species. We investigated the size structure of European perch (Perca fluviatilis) populations in lakes before and after dam removal by using the planned removals of

Genetic Diversity and Community Structure of Macrozoobenthos from Five Mangrove Forests in North Sumatra and Aceh, Indonesia

open access: yesIlmu Kelautan, 2022
Mangrove forests play an important role in macrozoobenthos ecology, assisting them in foraging, sheltering, and reproduction. In order to better understanding the genetic diversity and population genetic structure of macrozoobenthos, the mitochondrial ...

Decryption of Amphipod Cryptic Species: Ecological Differentiation of Syntopic Lineages of a Gammarus Species Complex

open access: yesFreshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Cryptic species represent an ever‐increasing proportion of discovered biological diversity. Thus, the number of observations of cryptic species co‐occurring in syntopy also increases, raising the question of mechanisms facilitating this phenomenon.

Species Richness and Abundance of Benthic Invertebrates Are Multiplied by Beaver (Castor sp.) Activities in Small Floodplains

open access: yesFreshwater Biology, Volume 70, Issue 5, May 2025.
ABSTRACT Beaver activities modify floodplains of small streams fundamentally. Prevailing lotic sections are supplemented with several additional habitats (e.g., ponds, dams and side channels). While there are several investigations into the invertebrate fauna of single beaver‐induced habitats, the ways beavers modify aquatic invertebrate assemblages of

Peculiarities of macrozoobenthos structure formation in riffles of the Karelian coast of the White sea

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015
Species composition, abundance and biomass of macrozoobenthos were investigated in the riffles of the Karelian coast of the White Sea. The longitudinal dynamics of benthic communities’ structure is weak due to the stony-bottomed riffles almost throughout
