International Journal of Ecology, Volume 2014, Issue 1, 2014., 2014 Aquatic environments are being modified by anthropogenic activities regarding their biological, physical, and chemical conditions; even pristine aquatic ecosystems can be threatened. This study focused on the biological monitoring of Maroaga Stream—a first order stream located in an Environmental Protection Area in the Amazon using the Biological ...

Water availability and land‐use shape the diversity of Odonata in the Middle East
Insect Conservation and Diversity, Volume 19, Issue 3, Page 621-633, May 2026.Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...

Biological Invasion and Coexistence in Intraguild Predation
Journal of Applied Mathematics, Volume 2013, Issue 1, 2013., 2013 Invasion of an exotic species initiated by its local introduction is considered subject to intraguild predation (IGP). Mathematically, the system dynamics is described by three nonlinear diffusion‐reaction equations in two spatial dimensions. The key factors that determine successful invasion are investigated by means of extensive numerical simulations.

Integrating eDNA and community science to monitor urban Odonata diversity
Insect Conservation and Diversity, Volume 19, Issue 1, Page 84-92, January 2026.Environmental DNA captured rare and underrepresented taxa often missed by community science observations. Community science revealed adult‐stage observations across a broader temporal window. Integrating both methods improved detection across life stages, seasons, and species prevalence.

Freshwater Biology, Volume 70, Issue 7, July 2025.ABSTRACT Aquatic insects are an abundant, yet declining, taxonomically heterogeneous group with special importance in both aquatic and terrestrial ecosystems. Accurate estimations of insect biomass during their aquatic life stages are essential to advance our fundamental knowledge about insects, their roles in ecosystems, and their vulnerability to ...

Stream Invertebrate Responses to Fine Sediment Depend on the Organic and Inorganic Components
Freshwater Biology, Volume 70, Issue 3, March 2025.ABSTRACT Excess fine sediment ( < 2 mm) is a pervasive stressor of aquatic systems at a global scale. To date, most research quantifying ecological response to deposited fine sediment has been conducted without distinguishing between the organic and inorganic components of fine sediment, leaving mechanistic understanding of how fine sediment affects ...

River Research and Applications, Volume 40, Issue 10, Page 2022-2034, December 2024.Abstract The presence of sediment‐burrowing clubtail dragonflies (Gomphidae) may be directly related to riverine geomorphic properties. Their synchronous emergence behavior, marked by persistent exuviae, allows for the examination of emerging adult‐stage habitats.

Ecology of Freshwater Fish, Volume 33, Issue 2, April 2024.Abstract Ecosystem engineers facilitate beneficiary species by ameliorating physical habitat. The stress‐gradient hypothesis (SGH) predicts the importance of facilitation in communities should increase with physical stress but has rarely been tested in freshwater.

, 2019 Live adult male specimens of C. brevistigma and W. atkinsoni have been collected from Shimla, Himachal Pradesh (India). Male germ cell chromosomes of the species are described on the basis of conventional staining, C-banding, silver nitrate staining and sequence specific staining. Both the species possesses 2n = 25m, as a diploid chromosome number and (
