Cannibalism by damselflies increases with rising temperature [PDF]

Biology Letters, 2017
Trophic interactions are likely to change under climate warming. These interactions can be altered directly by changing consumption rates, or indirectly by altering growth rates and size asymmetries among individuals that in turn affect feeding.

Diversity of Nearctic Dragonflies and Damselflies (Odonata)

Diversity, 2022
Rarely have studies assessed Odonata diversity for the entire Nearctic realm by including Canada, the United States, and Mexico. For the first time, we explored Odonata diversity in this region according to a definition of natural community assemblages and generated species distribution models (SDMs). Species occurrence data were assembled by reviewing

Philogenia nemesioi, a new damselfly from Peru (Odonata, Megapodagrionidae)

Revista Brasileira de Entomologia, 2013
Philogenia nemesioi, a new damselfly from Peru (Odonata, Megapodagrionidae). Philogenia nemesioi sp. nov. is described and illustrated based on one male specimen collected on forests of the eastern slope of the Peruvian Andes at 900 m.

Warming strengthens food web effects of predator phenotypic variation

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intraspecific variation modifies ecological processes and ecosystem functioning. Still, we know relatively little of how the nature and strength of ecosystem effects caused by intraspecific variation may interact with climate change.

Signature of ecological partitioning in the maintenance of damselfly diversity [PDF]

Journal of Animal Ecology, 2011
1. Ecological differences among co-occurring taxa are often invoked as an explanation for the maintenance of biodiversity. Whether these differences facilitate coexistence, which allows unequal competitors to remain in systems and thus maintain biodiversity, is still unclear. 2.

Odonata Assemblages in Urban Semi-Natural Wetlands

Insects
As the human population in urban areas is continuously growing, urbanization is one of the greatest threats to biodiversity. To mitigate the negative effects, the inclusion of blue zones (aquatic habitats) in modern urban development practices is ...

Urban developmental environments alter tadpole phenotypes depending on origin

Journal of Animal Ecology, EarlyView.
Urbanisation has rapidly altered the ecological and evolutionary contexts for many species. Using a reciprocal transplant experiment with frog larvae, we find that urban environments can alter morphological, developmental and behavioural traits at both ecological and evolutionary scales.

Dragonflies and Damselflies (Insecta: Odonata)

EDIS, 2019
The order Odonata contains the dragonflies and damselflies and is one of the most popular insect groups. Odonates are popular with both the amateur and professional because they are large, colorful, easily observable and have exceptionally charismatic behaviors.

Isolating the role of the matrix at patch and landscape scales

Journal of Animal Ecology, EarlyView.
This is the first experimental test of the spatial scales of matrix effects. Both patch‐scale and landscape‐scale matrix influence populations through a cross‐scale interaction altering survival, reproduction, and movement. Conservation in fragmentated landscapes should consider the matrix context of patches while focusing on local matrix due to its ...

Aquatic Macrophyte Vegetation Promotes Taxonomic and Functional Diversity of Odonata Assemblages in Intermittent Karst Rivers in the Mediterranean

Diversity, 2022
Assemblages of adult Odonata were studied in four intermittent karst rivers encompassing macrophyte-rich (MRH) and macrophyte-poor habitats (MPH) in southern Europe, where temporary lotic habitats are the predominant freshwater type but are still ...
