Effects of Mosquito Control Chemicals on Aquatic Fauna [PDF]
, 1974 No mosquito abatement districts have ever been organized in Arkansas. Mosquito control efforts have been largely adulticiding operations by either aerial application or ground thermal fogging machines.

Uncovering Ultrastructural Defences in Daphnia magna — An Interdisciplinary Approach to Assess the Predator-Induced Fortification of the Carapace [PDF]
, 2013 The development of structural defences, such as the fortification of shells or exoskeletons, is a widespread strategy to reduce predator attack efficiency. In unpredictable environments these defences may be more pronounced in the presence of a predator.

Ecology and Evolution, Volume 15, Issue 8, August 2025.Density‐dependent processes are important for a fundamental understanding of the regulation of populations. Laboratory experiments were conducted with the non‐biting midge Chironomus riparius (Diptera: Chironomidae) to investigate the impact of different combinations of food supply and larval densities on development and mortality.

Drivers and food web effects of Gonyostomum semen blooms [PDF]
, 2013 The flagellate Gonyostomum semen forms dense late-summer blooms in humic lakes and is a nuisance to swimmers because it forms a slimy coat on the skin, causing irritation in sensitive individuals. Increasing occurrence and bloom incidence of G. semen has

Oikos, Volume 2025, Issue 8, August 2025.Habitat coupling – where mobile predators forage over broad spatial scales and, in doing so, link food webs from semi‐discrete habitat patches – has emerged as a major structuring force in lake ecosystems. For the cold‐water apex predator lake trout Salvelinus namaycush, food‐web structure and morphometry‐driven accessibility to nearshore areas in ...

Evidence on Night Movements of Macroinvertebrates to Macrophytes in a Pampean Stream [PDF]
, 2014 Nocturnal invertebrate abundance peaks in lotic systems are usually associated to drift, however, diel migrations other than drift may be important in slow-flowing systems.

Freshwater Biology, Volume 70, Issue 7, July 2025.ABSTRACT We carried out short‐term field experiments (duration 1–3 days) to study the impact of predation by natural densities of Boeckella major on zooplankton in Australian ephemeral billabongs (oxbow lakes). Predation reduced total zooplankton densities by 33.6%–91.9%.

Journal of Fish Biology, Volume 107, Issue 1, Page 229-247, July 2025.Abstract Fishing‐induced evolution can impact fish trait distributions, with previous studies highlighting declines in size and age at maturation. However, the effects on fish growth remain less understood, and different fishing methods may exert distinct selection pressures on populations.

Fluctuations of the population of Daphnia laevis Birge 1878: a six-year study in a tropical lake
Brazilian Journal of BiologyThe fluctuation of the population of Daphnia laevis in Lake Jacaré (Middle River Doce, Minas Gerais) was monitored monthly (at one point in the limnetic region) for six years (2002-2007) as part of the Program of Long-Term Ecological Research (LTER/UFMG).
