An updated list of Odonata of southwestern Bangladesh

open access: yesJournal of Threatened Taxa, 2018
An odonate survey was conducted throughout the southwestern region of Bangladesh, concentrating on eight districts and the Sundarban, from August 2014 to August 2016.

The complete mitochondrial genome of Sympetrum striolatum (Odonata: Libellulidae) and phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2020
Here, we sequenced and annotated the complete mitogenome of Sympetrum striolatum (Odonata: Libellulidae). This mitogenome is 15,435 bp in length, consisting of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA unit genes, and

Observations on the Nesting of \u3ci\u3eCrabro Tenuis\u3c/i\u3e (Hymenoptera: Sphecidae) [PDF]

open access: yes, 2017
Three nests of Crabro tenuis were studied during June 1971-1972 in Oswego County, New York. Females constructed shallow but lengthy, multicelled nests in sand with the cells being built in clusters, sometimes in series. Females plugged the entrances with

Pests for Dinner: Dietary Composition of Insectivorous Bats in a Fragmented Tropical Dry Forest

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Insectivorous bats are key predators of a wide array of arthropods, including species that act as disease vectors and pests, yet such ecological roles remain poorly studied in tropical regions. In this study, we aimed to describe the diet of five insectivorous bat species from the genera Balantiopteryx, Myotis, Mormoops, and Pteronotus inhabiting a ...

The impact of climate-induced distributional changes on the validity of biological water quality metrics [PDF]

open access: yes, 2010
We present data on the distributional changes within an order of macroinvertebrates used in biological water quality monitoring. The British Odonata (dragonflies and damselflies) have been shown to be expanding their range northwards and this could ...

Global Biodiversity Framework Targets Can Drive Action on Insect Declines, but Lack Robust Indicators to Prove Their Effectiveness

open access: yesConservation Letters, Volume 19, Issue 2, March/April 2026.
ABSTRACT Insects are the most diverse and functionally important animals on Earth. In at least some regions, terrestrial populations are declining. Despite this, insects are often overlooked in conservation policy, and it is difficult to assess how anthropogenic threats and conservation actions affect insect populations.

Determinants of Terrestrial and Limnic Species Richness in Germany

open access: yesDiversity and Distributions, Volume 32, Issue 3, March 2026.
ABSTRACT Aim Biodiversity is increasingly threatened by human impacts. While abiotic conditions are well known to shape species richness, the role of human activities remains less clear. We examined how abiotic and human factors influence terrestrial and limnic species richness in a densely populated region with a long land‐use history.

Population structure and speciation in the dragonfly Sympetrum striolatum/nigrescens (Odonata: Libellulidae): An analysis using AFLP markers

open access: yesEuropean Journal of Entomology, 2009
There has been a long-standing debate as to whether Sympetrum striolatum (Charpentier, 1840) and the darker northern form, S. nigrescens (Lucas, 1912) should be recognised as separate species of dragonfly.

Urbanisation of Floodplains Reduces Species Richness of Several Taxonomic Groups Worldwide

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 3, March 2026.
ABSTRACT Aim Global urbanisation is one of the main threats to biodiversity worldwide, with consequences on human health. Many large urban areas are situated close to river floodplains to satisfy human needs. While studies have quantified the consequences of urbanisation on floodplain biodiversity at a local scale, no quantification exists at a global ...

The development of sexual differences in body size in Odonata in relation to mating systems

open access: yesEuropean Journal of Entomology, 2007
Adult body size is the result of important environmental, maternal and/or genetic effects acting on animals during development. Here we investigate how sexual size dimorphism (SSD) develops in seven species of Odonata: Anax imperator, Cordulegaster ...
