Flight of the dragons: a global review of migration in Odonata

open access: yesBiological Reviews, EarlyView.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.

Genome-wide data reveal bi-direction and asymmetrical hybridization origin of a fern species Microlepia matthewii

open access: yesFrontiers in Plant Science
IntroductionNatural hybridization is common and plays a crucial role in driving biodiversity in nature. Despite its significance, the understanding of hybridization in ferns remains inadequate.

The evidence base for ranger patrol effectiveness in conservation and how to improve it

open access: yesBiological Reviews, EarlyView.
ABSTRACT Ranger patrols are a cornerstone of wildlife protection efforts around the world and occur across all ecological governance systems. Evidence that patrols reduce threats to wildlife and enable their recovery has not been systematically examined previously.

Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

open access: yesIntegrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

Micropropagation of endangered plant species

open access: yesEcologia mediterranea, 1995
In vitro techniques can be used in the propagation and conservation of endangered species either for new plants or for intermediate or long term storage systems. Nevertheless, it is crucial to apply methods which maintain genetic integrity and avoid methods likely induce somatoclonal variation.

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife

open access: yesBiological Reviews, EarlyView.
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

Waders in a sea of debris: a global overview

open access: yesBiological Reviews, EarlyView.
ABSTRACT The impact of plastic pollution on ecosystems and marine fauna is well documented, although research into its effects on waders (also known as shorebirds) remains limited. Given that waders are exposed to coastal marine litter, this exposure could be a significant factor in the decline of their populations. This study aims to assess the global

Partners or passengers? Revisiting the association between diatoms and aquatic animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Genomic insights into the clonal reproductive Opuntia cochenillifera: mitochondrial and chloroplast genomes of the cochineal cactus for enhanced understanding of structural dynamics and evolutionary implications

open access: yesFrontiers in Plant Science
BackgroundThe cochineal cactus (Opuntia cochenillifera), notable for its substantial agricultural and industrial applications, predominantly undergoes clonal reproduction, which presents significant challenges in breeding and germplasm innovation. Recent
