Strong geographical variation in wing aspect ratio of a damselfly, Calopteryx maculata (Odonata: Zygoptera) [PDF]

, 2015
Geographical patterns in body size have been described across a wide range of species, leading to the development of a series of fundamental biological rules.

Scientists' warning on the need for greater inclusion of dragonflies in global conservation

Insect Conservation and Diversity, Volume 18, Issue 4, Page 465-484, July 2025.
Stressors to dragonflies are multiple, and in many cases interactive. Specialist species are at risk, while generalists can benefit from some human activities. Dragonflies are sentinels for conservation, being promising surrogates for other taxa while also being appealing to citizen science initiatives.

In honor of conservation of the Brazilian Atlantic Forest: description of two new damselflies of the genus Forcepsioneura discovered in private protected areas (Odonata: Coenagrionidae)

Zoologia (Curitiba), 2018
Two new Brazilian Protoneurinae damselflies, Forcepsioneura regua sp. nov. (holotype male deposited in DZRJ: Brazil, Rio de Janeiro State, Cachoeiras de Macacu municipality, RPPN Reserva Ecológica de Guapiaçu) and Forcepsioneura serrabonita sp.

Coloration in Argia damselflies of Central Mexico responds to changes in herbaceous vegetation La coloración de caballitos del diablo del género Argia responde a cambios en la cobertura de vegetación herbácea en el Centro de México

Insect Conservation and Diversity, Volume 18, Issue 4, Page 593-603, July 2025.
The increase in urban lands and the vegetation loss implies changes in the colour of the background which in turn could cause changes in the coloration of individuals. We measured changes in body lightness of damselflies through 19 sites in Central Mexico, with a different degree of urbanisation and a different percentage of native vegetation. We found

European Breeding Bird Declines Associated With Narrower Climatic Niches

Journal of Biogeography, Volume 52, Issue 7, July 2025.
ABSTRACT Aim Anthropogenic climate change has increasingly been identified as a major threat to global biodiversity. However, the extent of this threat is likely to be uneven across species, due to differences in life histories or exposure to environmental change.

Environmental noise reduces predation rate in an aquatic invertebrate [PDF]

, 2017
Noise is one of a wide range of disturbances associated with human activities that have been shown to have detrimental impacts on a wide range of species, from montane regions to the deep marine environment.

Influence of Lakeshore Riparian Vegetation on Diet, Feeding Rate, and Body Condition of Adfluvial Coastal Cutthroat Trout

Ecology and Evolution, Volume 15, Issue 6, June 2025.
Our research compares the diet, feeding rates, and condition of Coastal cutthroat trout in six small (1 km2 area) lakes with lakeshore riparian zones representing a gradient of logging histories. We identified positive relationships between the intake of terrestrial invertebrates by cutthroat and the percentage of riparian vegetation overhanging and ...

Some Insects Are More Equal Than Others: A Comparison of Popular Large Language Model Chatbots' Treatment of Different Insect Groups 昆虫间的不平等——主流大语言模型 (LLM) 对不同昆虫评价的比较研究

Integrative Conservation, Volume 4, Issue 2, Page 254-267, June 2025.
Our research demonstrates that in mirroring prevailing human biases towards different insect groups, LLM chatbots oversimplify insect diversity by predominantly restricting “bees” to honeybees and “wasps” to yellowjackets, neglecting the majority of biodiversity that includes wild bees and parasitoid wasps, while also favouring Nearctic species in ...
