An experimental test of interspecific competition between the alien boatman Trichocorixa verticalis and the native corixid Sigara lateralis (Hemiptera, Corixidae)

open access: yes, 2020
The corixid Trichocorixa verticalis originates from North America and is the only aquatic hemipteran alien to Europe. It is spreading in south-west Iberia where it is the dominant corixid in permanent, saline wetlands, where it may have excluded ...

Factors affecting intraspecific diet variation of ducklings: Niche partitioning in a heterogeneous landscape?

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Variability in resource use within populations of free‐ranging animals can influence demographic and evolutionary processes. Yet in many ecological systems, the extent of intra‐population variation in the resources that animals consume and the environmental factors that contribute to this variance remain poorly understood. For example, dietary

It is raining bugs: summer dispersal of aquatic bugs (Hemiptera, Heteroptera: Nepomorpha) in Srebarna Nature Reserve (Bulgaria)

open access: yesHistoria Naturalis Bulgarica, 2018
The Srebarna Nature Reserve is a wetland with great conservation value. The dispersal of aquatic bugs in it has not been studied earlier. Acquiring more data about the aquatic bug’s species composition and dispersal activity is a prerequisite for future ...

Nutrients and warm temperatures explain a seasonal cycle of colonization and ecosystem collapse in a floodplain pond

open access: yesEcosphere, Volume 16, Issue 11, November 2025.
Abstract Resilient ecosystems maintain similar species diversity and composition despite extreme environmental variation, while ecosystem collapse can be characterized by high mortality rates and decreased species diversity. Submerged aquatic macrophytes often support species diversity by providing habitat, shelter, food, and oxygen for fish and ...

Evidence on Night Movements of Macroinvertebrates to Macrophytes in a Pampean Stream [PDF]

open access: yes, 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.

Discharge and nutrients interact to determine trophic structure in a wetland: Evidence from a landscape‐scale manipulation

open access: yesLimnology and Oceanography, Volume 70, Issue 11, Page 3355-3369, November 2025.
Abstract Identifying drivers of consumer biomass patterns and community structure is complex for managed freshwater ecosystems that are sensitive to nutrients and drought. In the Florida Everglades, flow restoration is expected to reintroduce discharge across an expansive wetland, yet most research on consumers has focused on water depth and dry ...

Restoration of a brown trout (Salmo trutta L.) population to Loch Enoch, an acified Loch in Galloway, South-West Scotland [PDF]

open access: yes, 2000
The authors present the findings of a restoration project in Loch Enoch in Scotland. There are historical references that brown trout was present in Loch Enoch up to the 1920s but it is believed the acidity of loch triggered the disappearance of Salmo ...

Aquatic Invertebrates of the Devereux Slough - 2018 [PDF]

open access: yes, 2020
In 2018, the hardscape construction of NCOS (North Campus Open Space), a restored wetland on the Northern border of COPR (Coal Oil Point Reserve), was completed, thus approximately doubling the overall size of the wetland and offering the rather unique ...

Where Do You Fly From? Assessing Aerial Dispersal in Temporary Rivers Using Stable Isotopes

open access: yesFreshwater Biology, Volume 70, Issue 10, October 2025.
ABSTRACT Dispersal is a crucial ecological process that facilitates gene flow and species exchange within ecosystems. In temporary rivers (TRs), dispersal is a key driver of community assembly because it determines the ability of the organisms to adapt to seasonal drying and maintain stable populations.

Effects of carbofuran and metsulfuron-methyl on the benthic macroinvertebrate community in flooded ricefields Efeito do carbofurano e metsulfuron-methyl sobre a comunidade de macroinvertebrados bentônicos de lavoura de arroz irrigado

open access: yesActa Limnologica Brasiliensia, 2011
AIM: This study evaluated the effect of the insecticide carbofuran and the herbicide metsulfuron-methyl on the abundance and diversity of benthic macroinvertebrates in a paddy ricefield.
