Effects of water temperature on freshwater macroinvertebrates: a systematic review

open access: yesBiological Reviews, Volume 98, Issue 1, Page 191-221, February 2023., 2023
ABSTRACT Water temperature is one of the main abiotic factors affecting the structure and functioning of aquatic ecosystems and its alteration can have important effects on biological communities. Macroinvertebrates are excellent bio‐indicators and have been used for decades to assess the status of aquatic ecosystems as a result of environmental ...

Length–biomass equations to allow rapid assessment of semi‐aquatic bug biomass in tropical streams

open access: yesEntomologia Experimentalis et Applicata, Volume 171, Issue 2, Page 102-115, February 2023., 2023
Length–biomass equations provide a cost‐effective way of deriving biomass, but relationships vary between taxa and habitats. Semi‐aquatic bugs are bioindicators and prey items for predators. We identify the best‐fit equations to predict the biomass of semi‐aquatic bugs collected in Sabah, Malaysia.

Resource use of crucian carp along a lake productivity gradient is related to body size, predation risk, and resource competition

open access: yesEcology of Freshwater Fish, Volume 32, Issue 1, Page 10-22, January 2023., 2023
Abstract Generalist fish species can feed on a wide resource spectrum and across trophic levels depending on resource availability and trophic interactions. Crucian carp (Carassius carassius) represents a good candidate species to investigate variation in the trophic ecology of generalist fish as it can be found in highly variable fish communities and ...

Algorithms, nymphs, and shepherds

open access: yesTheoretical Computer Science, 2002
AbstractComputability and complexity are the two major lines along which the science of algorithms has evolved; but the same concepts guide many human activities. We try to catch some glimpses of the connections between these two worlds, to meet the expectations of the audience. We will encounter nymphs and universal Turing Machines, ancient traditions
