From roads to biobanks: Roadkill animals as a valuable source of genetic data

PLoS ONE, Год журнала: 2023, Номер 18(12), С. e0290836 - e0290836

To protect biodiversity we must understand its structure and composition including the bacteria microparasites associated with wildlife, which may pose risks to human health. However, acquiring this knowledge often presents challenges, particularly in areas of high where there are many undescribed poorly studied species funding resources can be limited. A solution fill gap is sampling roadkill (animals that die on roads as a result collisions circulating vehicles). These specimens help characterize local wildlife their parasites fewer ethical logistical challenges compared traditional specimen collection. Here test approach by analyzing 817 tissue samples obtained from 590 vertebrate (Amphibia, Reptilia, Aves Mammalia) collected within Tropical Andes Ecuador. First, tested if quantity quality recovered DNA varied across at different times since death, exploring decomposition affected potential identify microorganisms. Second, stability taxa tissues limitations offer recommendations for future work. Finally, illustrate how these aid taxonomic identification parasite detection. Our study shows biodiversity. was amplified (allowing detection) even 120 hours after although risk degradation increased overtime. extracted all classes but smaller quantities lower amphibians.

Additional testing environmental traffic conditions needed, our results show detect potentially monitor could valuable create biobanks preserve genetic data.

Road mortality of water snakes in light of landscape structure and traffic intensity in north-eastern Hungary

PeerJ, Год журнала: 2024, Номер 12, С. e17923 - e17923

Road mortality can be a serious threat to different animals, including snakes. However, patterns vary between species, intraspecific groups, locations and time. We compared the number of road-killed individuals (carcasses) two semiaquatic water snakes ( Natrix natrix N. tessellata ) on 58 km road sections bordered by an active floodplain flood-protected former one side mountainous areas other in NE Hungary based surveys conducted once every weeks three non-consecutive years. The results showed high snakes, with spring autumn peak corresponding times when emerge from return hibernating sites. show that small-scale spatial differences were mediated landscape structure along road, while effects traffic volume, flood regime age sex negligible. For conservation, study suggests establishing culvert passages under and/or artificial sites floodplain-side roads critical promising reducing road-related mortality.

Bird and mammal roadkill patterns and associated factors on a tropical mountain area: the Interamerican Highway, Cerro de la Muerte, Costa Rica

Context Habitat degradation caused by roads and wildlife–vehicle collisions are two of the main drivers terrestrial vertebrate mortality. Spatial collision patterns influenced habitat road characteristics species’ ecology biology, including its life history. Costa Rica has a network 10,000 km paved roads; however, there is knowledge gap on impact to wildlife. Understanding interconnectedness roadkill with spatial temporal crucial mitigate this threat in country. Aims Here, we describe bird mammal–vehicle 45 section Interamerican Highway identify critical zones that require attention. Methods Surveys were conducted car between Río Macho Forest Reserve Los Santos for period 8 months. We recorded mammal individuals landscape features 100 m sections hotspots. used information try explain hotspot segments using generalized linear models.

Gut bacterial communities in roadkill animals: A pioneering study of two species in the Amazon region in Ecuador

PLoS ONE, Год журнала: 2024, Номер 19(12), С. e0313263 - e0313263

Studying the microbial communities within gastrointestinal tract of vertebrate species can provide insights into biodiversity, disease ecology, and conservation. Currently, we have very limited understanding composition endogenous microbiota in wildlife, particularly high biodiversity tropical areas. Knowledge is by logistical ethical challenges obtaining samples for free-living animals. Roadkill carcasses offer a largely untapped source biological material, including gut microbiota. These animals that died on roads due to collisions with vehicles are suitable accessible, opportunistic sampling. Here, used metabarcoding V 3 —V 4 region 16S rRNA gene nine roadkill collected from road Ecuador representing two species: speckled worm lizard ( Amphisbaena bassleri ) smooth-billed ani Crotophaga ). We successfully identify phyla both Firmicutes, Bacteroidetes, Proteobacteria A . , Firmicutes Actinobacteria C Our study provides first description these vertebrates, demonstrates feasibility studying material be opportunistically preserved biobanks.
