Assessing the Relationship Between Macroinvertebrate Metrics and Fine Sediment Index for Ecological Biomonitoring in the Little Akaki River, Addis Ababa, Ethiopia. [PDF]
Habitat quality had a positive correlation with percentage of Ephemeroptera, percentage of EOT, and Shannon diversity index (r = 0.833, r = 0.880, and r = 0.939, respectively). PSI had positive correlation with number of taxa, and ASPT‐ETHbios (r = 0.819, and r = 0.798, respectively). Most sites were heavily sedimented.

Testing the Optimal Foraging Theory in a Generalist Feeder: The Case of Reintroduced European Pond Turtles and Its Impact on Macroinvertebrates Communities. [PDF]
In this study we investigated the macroinvertebrate (MI) communities in two newly created, man‐made ponds concurrently with the diet of captive‐bred European pond turtles that were translocated there. We aimed at assessing whether turtles were operating as generalist feeders, and if successive reintroductions of turtles would affect the overall MI ...

Instances of heat waves and cold snaps are becoming more frequent and of increasing duration worldwide. It is well established that short exposure to high or low-temperatures, such as during extreme weather events, often results in adaptive (acclimation ...

Relative Effects of Eutrophication and Warming on Freshwater Ecosystems Across Ecological Levels. [PDF]
This experimental study explores the effects of global change on different ecological levels. We demonstrate that warming primarily impacts lower ecological levels, such as community composition, whereas eutrophication predominantly affects the most integrative ecological level, that is, ecosystem.

Sympecma fusca and Coenagrion caerulescens mainly deposit their eggs into floating dead parts of emergent plants. In their initial choice of oviposition site (selection of landing site) S. fusca does not distinguish between fresh and dead plant material,

Mating success is linked to reproductive success in males, but parameters influencing it are poorly known. The relationships between lifetime mating success (LMS), fluctuating asymmetry (FA), body size (SIZE), reproductive period (RP) and emergence date (

Geographic range expansion is one of the best documented macroecological consequences of climate change. A concomitant change in morphology has been demonstrated in some species. The relationship between latitudinal variation in morphology (e.g. Bergmann'

The efficiency of an alternative method of collection (by suction of water) for the study of Culicidae and Chironomidae (Diptera), Scirtidae (Coleoptera) and Coenagrionidae (Odonata) in bromeliads with different foliar architecture in a restinga at ...
