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.

1153. Anisoptera megistocarpa Slooten
Curtis's Botanical Magazine, Volume 42, Issue 2, Page 303-320, June 2025.Summary Anisoptera megistocarpa Slooten, a large tree of the lowland undulating forests, and low hills of northern Sumatra, southeastern Thailand, Peninsular Malaysia and Singapore, is described and illustrated. This species has a massive, buttressed trunk reaching a height of 50 m, 4 m girth and an emergent crown. The reddish‐brown undersurface of the

Fossil gaps inferred from phylogenies alter the apparent nature of diversification in dragonflies and their relatives [PDF]
, 2011 Background The fossil record has suggested that clade growth may differ in marine and terrestrial taxa, supporting equilibrial models in the former and expansionist models in the latter. However, incomplete sampling may bias findings based on fossil data

Journal of Fish Biology, Volume 106, Issue 6, Page 1876-1888, June 2025.Abstract The tidal freshwater zone is an aquatic transition zone that links a river to its estuary and provides an important habitat used in the life cycle of resident and migratory fishes. Yet, information on the trophic structure of fishes in this habitat is scarce. To address this gap, we characterize the trophic structure of a fish community in the

Complex Life Cycles Shape the Functional Biogeography of European Dragonflies
Global Ecology and Biogeography, Volume 34, Issue 5, May 2025.ABSTRACT Aim To investigate how trait correlations between life stages associated with complex life cycles (aquatic nymph and terrestrial adult) shape the functional diversity and trait–environment relationships of European dragonflies (Odonata: Anisoptera). Location European mainland. Time Period Pre‐1990 and post‐1990. Major Taxa Studied Dragonflies (

TAXON, Volume 74, Issue 2, Page 361-385, April 2025.Abstract Malvales is a diverse order of flowering plants, economically and ecologically relevant, and it is known for its broad morphological variability. Recent phylogenomic studies have revealed a complex evolutionary history for the order, including localised phylogenetic discordances among nuclear loci.
