Contribution to the Odonata of the Kingdom of Tonga [PDF]

open access: yes, 2013
New data on the Odonata fauna of the Kingdom of Tonga is provided following re-search carried out on Tongatapu and 'Eua islands in July 2012. New localities for Tongatapu Island are put on record and previous studies are compared with new pheno-logical ...

A Shift to Metapopulation Genetic Management for Persistence of a Species Threatened by Fragmentation: The Case of an Endangered Australian Freshwater Fish

open access: yesMolecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT In a world where habitats are degrading and the climate is warming and becoming unpredictable, biodiversity conservation efforts and funding remain grossly inadequate. As part of a multifaceted approach to halting extinctions, shifting from preserving small, remnant populations to a practice of genetically connecting populations that recreate ...

Associations of dragonflies (Odonata) to habitat variables within the Maltese Islands : a spatio-temporal approach [PDF]

open access: yes, 2012
Relatively little information is available on environmental associations and the conservation of Odonata in the Maltese Islands. Aquatic habitats are normally spatio-temporally restricted, often located within predominantly rural landscapes, and are ...

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 ...

An integrated study of the development of organic rice cultivation in the Camargue (France)- [PDF]

open access: yes, 2004
In the Camargue, rice and durum wheat are associated in rotations that have an ambivalent ecological impact: on the one hand, these two crops contribute to the preservation of the surrounding ecosystem, while on the other hand, when cropped intensively ...

Widespread Decline of Ground Beetles in Germany

open access: yesDiversity and Distributions, Volume 31, Issue 11, November 2025.
ABSTRACT Aim Many insect species are facing existential crises, primarily due to diverse human activities. Most insect assessments, however, are based on relatively short time series or some iconic species. Here, we assess how the occupancy of ground beetles has changed in Germany over the last 36 years. Location Germany. Methods In close collaboration

Time Constraints Modulate the Effects of Predator Cues and a Metal Across Life Stages in a Damselfly

open access: yesEvolutionary Applications, Volume 18, Issue 11, November 2025.
ABSTRACT Animals are increasingly exposed to multiple co‐occurring stressors. Environmental factors such as seasonal time constraints (TC), predation risk, and pollutants strongly influence fitness‐related traits in aquatic organisms. Yet, the interactive effects of such stressors, especially across life stages, remain unclear.

So close, but yet so far: Assessing the community structure of Odonates in two adjacent rivers within different watersheds in Souk Ahras, North East of Algeria [PDF]

open access: yesJournal of Insect Biodiversity and Systematics
Lotic systems are rapidly changing due to anthropogenic impacts, making it crucial to note the diversity and abundance of Odonates for effective conservation of these running waters.

Incidence of Anagrus obscurus (Hymenoptera: Mymaridae) egg parasitism on Calopteryx haemorrhoidalis and Platycnemis pennipes (Odonata: Calopterygidae, Platycnemididae) in Italy [PDF]

open access: yes, 2011
Very little is known about the incidence of egg parasitoids in odonates, perhaps because Odonata eggs are well protected in stems or leaves, sometimes below water.
