Abstract Global biodiversity in freshwater and the oceans is declining at high rates. Reliable tools for assessing monitoring aquatic biodiversity, especially rare secretive species, are important efficient timely management. Recent advances DNA sequencing have provided a new tool species detection from present environment. In this study, we tested whether an environmental ( eDNA ) metabarcoding approach, using water samples, can be used addressing significant questions ecology conservation....
The precise knowledge of species distribution is a key step in conservation biology. However, detection can be extremely difficult many environments, specific life stages and populations at very low density. aim this study was to improve the on DNA persistence water order confirm presence focus freshwater ecosystems. Aquatic vertebrates (fish: Siberian sturgeon amphibian: Bullfrog tadpoles) were used as target species. In control conditions (tanks) field (ponds), detectability decreases with...
Summary 1. Alien invasive species (AIS) are one of the major causes biodiversity loss and global homogenization. Once an AIS becomes established, costs control can be extremely high complete eradication is not always achieved. The ability to detect a at low density greatly improves success decreases both impact on ecosystems. 2. In this study, we compare sensitivity traditional field methods, based auditory visual encounter surveys, with environmental DNA (eDNA) survey for detection American...
Comparative studies of mortality in the wild are necessary to understand evolution aging; yet, ectothermic tetrapods underrepresented this comparative landscape, despite their suitability for testing evolutionary hypotheses. We present a study aging rates and longevity across tetrapod ectotherms, using data from 107 populations (77 species) nonavian reptiles amphibians. test hypotheses how thermoregulatory mode, environmental temperature, protective phenotypes, pace life history contribute...
Pressures on freshwater biodiversity in Southeast Asia are accelerating, yet the status and conservation needs of many region's iconic fish species poorly known. The Mekong is highly diverse supports four six largest globally, three which, including giant catfish (Pangasianodon gigas), Critically Endangered. Emerging environmental DNA (eDNA) techniques have potential for monitoring threatened biodiversity, not been applied complex biodiverse tropical ecosystems such as Mekong. We developed...
The early detection and identification of pathogenic microorganisms is essential in order to deploy appropriate mitigation measures. Viruses the Iridoviridae family, such as those Ranavirus genus, can infect amphibian species without resulting mortality or clinical signs, they also other hosts than species. Diagnostic techniques allowing pathogen outside period host die-off would thus be particular use. In this study, we tested a method using environmental DNA (eDNA) on population common...
Plastic forms the majority (i.e. 75%) of marine waste with 14.5 million tons per year dumped into oceans. Once at sea, sunlight, wind, and wave action break down macroplastic small particles. These microplastics (MPs, particles between 0.1 µm 5 mm), which can also directly originate from industrial production are ubiquitous likely to persist in environment for centuries. Recent studies show that range animals capable ingesting these MPs spans entire fauna. The effects MP ingestion diverse...
Dispersal is a central component of life history evolution. An increasing number studies suggest that spatiotemporally variable environments may promote the evolution "dispersal syndromes," consisting covariation patterns between dispersal and morphological, physiological, behavioral, traits. At interspecific scale, "colonizer syndrome" appears to be one most frequently recorded associations traits, linking high rate, fecundity, short lifespan as systematically combined adaptations in...
Abstract In Western Europe, habitat loss and landscape fragmentation has led to significant population decline in various animal groups, including amphibians. The extinction of the last natural populations yellow‐bellied toad Belgium, Luxembourg several regions southern western France suggests a widespread decline. By using site‐occupancy models adding covariates corresponding human‐influenced features landscape, we tried identify relative effects different land‐use types on species’...
Parasitic chytrid fungi have emerged as a significant threat to amphibian species worldwide, necessitating the development of techniques isolate these pathogens into culture for research purposes. However, early methods isolating chytrids from their hosts relied on killing amphibians. We modified pre-existing protocol infected animals use toe clips and biopsies webbing rather than euthanizing hosts, distributed researchers part BiodivERsA project RACE; here called RML protocol. In tandem, we...
Detection is crucial in the study and control of invasive species but it may be limited by methodological issues. In amphibians, classical survey techniques exhibit variable detection probability depending on are often constrained climatic conditions requiring several site visits. Furthermore, reduced at low density because capture (passive traps), or activity (acoustic surveys) drop. Such limits impair typical onset colonisation a site. last few years, environmental DNA (eDNA) methods have...
Abstract Spatial and temporal monitoring of species threatened with extinction is critical importance for conservation ecosystem management. In the Mediterranean coast, fan mussel ( Pinna nobilis ) listed as critically endangered after suffering from a mass mortality event since 2016, leading to 100% in most marine populations. Conventional this macroinvertebrate done using scuba, which challenging dense meadows or low visibility. Here we developed an environmental DNA assay targeting...
Starting in 2010, rapid fire salamander (Salamandra salamandra) population declines northwestern Europe heralded the emergence of Batrachochytrium salamandrivorans (Bsal), a salamander-pathogenic chytrid fungus. Bsal poses an imminent threat to global diversity owing its wide host range, high pathogenicity, and long-term persistence ecosystems. While there is pressing need develop further research conservation actions, data limitations inherent recent pathogen obscure necessary insights into...
Abstract Background Mitigating the effect of linear transport infrastructure (LTI) on fauna is a crucial issue in road ecology. Wildlife crossing structures (tunnels or overpasses) are one solution that has been implemented to restore habitat connectivity and reduce wildlife mortality. Evaluating how these crossings function for small often recommended but, mainly due technical limitations, not conducted practice only as short-term monitoring (less than 1 year). In this study, we developed...
Abstract Skeletochronology was used to determine the ages of 30 loggerhead sea turtles ( Caretta caretta ) found in French Mediterranean waters. Histological sections were performed with humeri collected on stranded C. coast Provence and Gulf Lion. Lines arrested growth (LAGs) evaluate age, considering only one period per year. Two successive LAGs delimit an interval that is proportional individual’s body growth. In a first step, we created skeletogram for each individual identified its...
Linear transport infrastructure can impact wildlife directly or indirectly, and amphibians are particularly affected. In some cases, mitigation measures – such as tunnels below the linear implemented, but an evaluation of their effectiveness is often lacking, especially for small animals amphibians. Few studies have focused on crossing behaviour in underpasses, yet this information may be crucial to improve measures. study, we conducted experiments three a high-speed railway with...
