Long unobserved and recently discovered: towards a better understanding of protected‐area species dynamics using curated species lists

open access: yesEcography, EarlyView.
Protected areas are designed to shield populations from harmful human impacts. However, in the face of global climate change, a static approach to conservation within these areas is neither feasible nor desirable. One key measure of ecological change at this scale is the arrival of new species and the local extinction of others. Despite strong interest

Phylogenetically‐Informed Crayfish Conservation in the Face of Climate Change

open access: yesAnimal Conservation, EarlyView.
Crayfish are a vital part of freshwater ecosystems, yet one third of assessed species are threatened with extinction, and almost 90% are highly sensitive to climate change. In this study, we produced a phylogenetically‐informed species prioritisation for crayfish conservation and explored the impacts of projected climate change scenarios on crayfish ...

Diversity of Odonates (Odonata, Anisoptera & Zygoptera) in the Theniet El ‎Had National Park-North West of Algeria [PDF]

open access: yesJournal of Insect Biodiversity and Systematics, 2023
The aim of this study is to make an inventory of the fauna of the Odonata in Theniet El Had National Park, which helps managers to make appropriate decisions for the conservation of these species. The site is entirely forested (Cedrus and Quercus species)

Visual Cues Can Alter the Behavioural Responses of Dragonfly Larvae to Chemical Alarm Cues

open access: yesEthology, EarlyView.
Using a controlled experimental approach, we examined how chemical and visual cues influence antipredator behaviour in Aeshna cyanea larvae and tested whether risk‐related information can be socially transmitted among nearby conspecifics. Our results show that dragonfly larvae do not copy the antipredator responses of others, but visual cues alter how ...

An annotated checklist of Odonata (Insecta) of Kanha Tiger Reserve and adjoining areas, central India

open access: yesJournal of Threatened Taxa, 2013
Odonates were recorded from Kanha Tiger Reserve and its adjoining areas during January-December 2010. Thirty eight species were recorded belonging to seven families and 26 genera. Twelve species distribution is first time recorded from the reserve.

Using Eye Lens Stable Isotopes to Identify the Rearing Origin of Fall Age‐0 Walleye (Sander vitreus)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Isotope values in fish eye lenses may be useful in differentiating rearing origins. We compared eye lens isotopic values of fall fingerling age‐0 walleye (Sander vitreus) reared in a hatchery pond, a recirculating aquaculture system (RAS), and a natural lake. Using 10 fish per rearing source, we delaminated layers from one eye lens per fish to

Forecasting Divergence: Climate-Driven Habitat Shifts in North American Odonates Depend on Functional Groups

open access: yesConservation
Climate change is expected to have significant yet distinct impacts on arthropods. Studying the species distribution of odonates, which are considered a model taxon for studying climate change and a flagship group for assessing ecosystem health, can ...

The first record of parasitism by Forcipomyia (Diptera: Ceratopogonidae) in Cuban odonates

open access: yesNovitates Caribaea, 2019
Several species of biting midges of the genus Forcipomyia are frequently found attached to the wings of adult odonates, acting as parasites by sucking haemolymph from the wing veins. Here we report the first finding of F.
