Assessing the Relationship Between Macroinvertebrate Metrics and Fine Sediment Index for Ecological Biomonitoring in the Little Akaki River, Addis Ababa, Ethiopia. [PDF]
Ecol EvolHabitat 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.

Sex on the Beach: Sexual Size Dimorphism Among Aquatic Bugs (Nepomorpha) Inhabiting Different Habitats. [PDF]
Ecol EvolWe examined the degree of sexual size dimorphism (SSD), based on body length, in approximately 45% of known water bug (Nepomorpha) species. Contrary to our initial hypothesis, we found that females are not significantly longer than males in most species. Our research revealed that habitat plays a significant role in SSD.

The Relationship between Benthic Macroinvertebrate Assemblages and Water Quality Parameters in the Sanyati Basin, Lake Kariba, Zimbabwe. [PDF]
ScientificWorldJournal, 2022 Biological monitoring of reservoirs is important in assessing aquatic health. This study aimed at assessing the structure of benthic macroinvertebrate communities in relation to physicochemical parameters along Sanyati basin shoreline in Lake Kariba, Zimbabwe.

Anticipating where are unknown aquatic insects in Europe to improve biodiversity conservation
Diversity and Distributions, Volume 29, Issue 8, Page 1021-1034, August 2023., 2023 Abstract Aim Understanding biodiversity patterns is crucial for prioritizing future conservation efforts and reducing the current rates of biodiversity loss. However, a large proportion of species remain undescribed (i.e. unknown biodiversity), hindering our ability to conduct this task.

Biological Reviews, Volume 98, Issue 3, Page 942-981, June 2023., 2023 ABSTRACT Acoustic and substrate‐borne vibrations are among the most widely used signalling modalities in animals. Arthropods display a staggering diversity of vibroacoustic organs generating acoustic sound and/or substrate‐borne vibrations, and are fundamental to our broader understanding of the evolution of animal signalling.

Freshwater Biology, Volume 68, Issue 2, Page 325-339, February 2023., 2023 Abstract Worldwide, riparian zones of many intermittent rivers and ephemeral streams (IRES) have been severely degraded. However, compared with perennially flowing waters, there have been few restoration efforts (e.g., revegetation, livestock removal) to halt or reverse this degradation.

Testing the Optimal Foraging Theory in a Generalist Feeder: The Case of Reintroduced European Pond Turtles and Its Impact on Macroinvertebrates Communities. [PDF]
Ecol EvolIn 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 ...

Spatial Variations in Aquatic Insect Community Structure in the Winam Gulf of Lake Victoria, Kenya
International Journal of Ecology, Volume 2023, Issue 1, 2023., 2023 Background. Aquatic insect community structure is dynamic due to threats by anthropogenic activities coupled with changing climatic conditions. The insect’s survival is dependent on the substrate, water quality, and environmental effects. The changes in water quality influence their distribution and abundance and are reflected in spatial and temporal ...

Ecology and Evolution, Volume 12, Issue 12, December 2022., 2022 A small change in salinity (5‰ vs 7‰) cause total turnover of wolf spider species composition. Wolf spider diets do not vary between species. Wolf spider diets differ between sites with or without a thick wrack bed. Abstract Wolf spiders are typically the most common group of arthropod predators on both lake and marine shorelines because of the high ...

Savanna vegetation increase triggers freshwater community shifts
Global Change Biology, Volume 28, Issue 23, Page 7023-7037, December 2022., 2022 Large mammalian herbivores inhabiting savanna landscapes are known to shape adjacent freshwater bodies, which are used by a wide variety of species during reproduction. Following a period of intensified poaching in Comoé National Park, Ivory Coast, we quantified major vegetation increase in small temporary ponds, which resulted in significant ...
