The last species list of the European herpetofauna was published by Speybroeck, Beukema and Crochet (2010). In the meantime, ongoing research led to numerous taxonomic changes, including the discovery of new species-level lineages as well as reclassifications at genus level, requiring significant changes to this list. As of 2019, a new Taxonomic Co...

In dit rapport, dat samen met de vijf provinciale rapporten één geheel vormt, beschrijven we de procedure voor de afbakening van provinciaal prioritaire soorten, maar ook van andere soorten die voor het provinciale natuurbehoud en/of -beleid van belang kunnen zijn. Naast provinciaal prioritaire soorten sensu Bauwens et al. (2001), waarbij de soorte...

Sex-related differences in mortality are widespread in the animal kingdom. Although studies have shown that sex determination systems might drive lifespan evolution, sex chromosome influences on aging rates have not been investigated so far, likely due to an apparent lack of demographic data from clades including both XY (with heterogametic males)...

Door het verlies aan habitat kwam de vroedmeesterpad in Vlaanderen in een zeer precaire situatie terecht. In 2017 werd een Soortenbeschermingsprogramma (SBP) opgesteld ter ondersteuning van de soort. In dit plan worden allerlei maatregelen voorgesteld, waaronder het opzetten van een kweekprogramma als laatste redmiddel om bestaande populaties te ve...

We report on an established population of the beauty rat snake, Elaphe taeniura Cope, 1861, a large, oviparous colubrid native to Southeastern Asia, in Belgium. The snakes have invaded a railroad system next to a city in the northeast of the country. Sightings exist from an area of 208 km², yet the core distribution is estimated to be no more than...

ContextTerrestrial landscapes surrounding aquatic habitat influence the persistence of amphibian spatially structured populations (SSPs) via their crucial role in providing estivation and overwintering sites, facilitating or hampering dispersal and colonisation, and consequently the maintenance or loss of genetic diversity.Objectives To highlight t...

As part of the Flemish common midwife toad (Alytes obstetricans) species protection programme, the Research Institute for Nature and Forest (INBO) runs a breeding project. Goals are to sustain existing populations (through supplementation) and to found new populations (through (re)introduction). Ex situ breeding is conducted in several breeding...

While epizootics increasingly affect wildlife, it remains poorly understood how the environment shapes most host-pathogen systems. Here, we employ a three-step framework to study microclimate influence on ectotherm host thermal behaviour, focusing on amphibian chytridiomycosis in fire salamanders (Salamandra salamandra) infected with the fungal pat...

Loss and degradation of its habitat have led the Common Midwife Toad (Alytes obstetricans) in Flanders, Belgium, into a very precarious state. A Species Protection Program was launched in 2017. This is an official policy document with binding commitments. It proposes all kinds of measures, including the establishment of a breeding program as a last...

Monthly monitoring data between 2013 and 2018 are used to investigate and document the recovery of the hyperbenthic community in the Sea Scheldt, the Belgian part of the Scheldt estuary after a long-lasting state of hypoxia, and to identify ecological drivers of the current community. Hyperbenthos was present in all studied salinity zones and was t...

Available research is inconclusive on how circatidal habitat use and cross-shore distribution of aquatic epibenthic predators may affect the vertical zonation of infauna in muddy, soft-bottom substrates in estuaries. We placed fyke traps at different heights on the intertidal mudflat to assess the circatidal density of epibenthic predators. Infauna...

By realising the conservation objectives for European habitats it is assumed that a large number of species will benefit from these measures as well. In this analysis, we test this hypothesis for 142 species of conservation priority in Flanders. To do so, we use the potential habitat approach, i.e. mechanistic models that translate the ecological p...

Red Lists estimate the extinction risk of species at global or regional levels and areimportant instruments in conservation policies. Global Red List assessments are readilyavailable via the IUCN website (https://www.iucnredlist.org) and are regularly updated by(taxonomic) experts. Regional Red Lists, however, are not always easy to find and oftenu...

Mudflats and shallow water areas have been put forward as important ecotopes in the LangeTermijnVisie 2030 (LTV) and the Ontwikkelingsschets 2010 voor het Schelde-estuarium (OS) by the VNSC (Flemish-Dutch Scheldt committee). The OS states that within the subtidal area, low dynamic shallow water zones are of highest value to macro- and hyperbenthos,...

A recent paper has suggested that NA2RE, the New Atlas of Amphibians and Reptiles of Europe, does not provide a reliable basis for ecological niche modelling studies due to errors flagging introductions and missing data for the native range of the pond turtle genus Emys. We point out that the original NA2RE paper already acknowledged that it was no...

Solid population studies depend on reliable capture-mark-recapture (CMR) methodology. The available methods for such studies on amphibians are often invasive, unsuitable for long-term studies, time-consuming and/ or expensive. We present a new software tool, connected to a MS Access database, ManderMatcher, for CMR study of fire salamanders (Salama...

Nature policy and management often uses threatened and regionally important species as tools or goals. Knowledge about their ecology and distribution is, therefore, crucial to scientifically underpin conservation measures. Apart from known observations, sites where the focal species is not (yet) observed or sites where potentially suitable ecologic...

En 2012, un nouveau champignon, le Batrachochytrium salamandrivorans (Bsal), a été découvert aux Pays-Bas. Ce champignon provoque chez les amphibiens une infection mortelle de la peau (chytridiomycose) et a conduit la population hollandaise de salamandres au bord de l’extinction. En 2016, 99,9% de la population de salamandres avait disparu. En 2013...

Emerging fungal diseases can drive amphibian species to local extinction. During 2010-2016, we examined 1,921 urodeles in 3 European countries. Presence of the chytrid fungus Batrachochytrium salamandrivorans at new locations and in urodeles of different species expands the known geographic and host range of the fungus and underpins its imminent th...

In 2014, we compiled the first potentially suitable habitat maps for species of European concern and of Flemish priority species based solely on the Flemish Biological Valuation Map (BWK). In a second phase, we used four methods to refine these maps: 1) mechanistic modelling, 2) correlative modelling, 3) downscaling correlative models to a higher r...

At the request of the Agency for Nature and Forests (ANB), we investigated the feasibility of grouping 145 European and Flemish priority species into so called multispecies action or recovery plans. As a starting point, we used the classification into landscape and ecological species profiles of Van Uytvanck & Goethals (2014). To add species to the...

A precise knowledge of the spatial distribution of taxa is essential for decision-making processes in land management and biodiversity conservation, both for present and under future global change scenarios. This is a key base for several scientific disciplines (e.g. macro-ecology, biogeography, evolutionary biology, spatial planning, or environmen...

The use of static indicator species, in which species are expected to have a similar sensitivity or tolerance to either natural or human-induced stressors, does not account for possible shifts in tolerance along natural environmental gradients and between biogeographic regions. Their indicative value may therefore be considered at least questionabl...

For the first time, the freshwater oligochaete species Bratislavia dadayi (Michaelsen, 1905) is recorded in Europe. The species was found at three subtidal stations in the Schelde estuary in Belgium, where it was probably introduced from the Americas. We provide an overview of the species’ nomenclature, diagnostics, distribution, and ecology. Brati...

Latitudinal clines in species diversity in limnic and terrestrial habitats have been noted for well over a century and are consistent across many taxonomic groups. However, studies in marine systems over the past 2 to 3 decades have yielded equivocal results. We conducted initial analyses of the MarBEF (EU Network of Excellence for Marine Biodivers...
