The invasive raccoon (Procyon lotor) is an abundant carnivore and considered as important potential vector of infectious diseases parasites in Europe. Raccoons show a broad, opportunistic, omnivorous food spectrum. Food supply habitat quality urban areas are very attractive for the generalist raccoon. This inevitably leads to increased interaction with humans, domestic animals livestock, making potentially suitable zoonosis vector. In its autochthonous range, especially Eastern Midwestern United States, has been studied intensively since beginning 20th century. Whereas, basic field biology parasitology studies Germany Europe lacking have only conducted sporadically, regionally on small sample sizes. presented study 234 raccoons from central were comprehensively examined their metazoan parasite fauna. present shows first time extremely diverse fauna outside native range proves essential role intermediate hosts ecto- endoparasites.

Passive Acoustic Monitoring as a Tool to Investigate the Spatial Distribution of Invasive Alien Species

Remote Sensing, Год журнала: 2022, Номер 14(18), С. 4565 - 4565

Опубликована: Сен. 13, 2022

Invasive alien species (IAS) are a threat to biodiversity and ecosystem function worldwide. Unfortunately, researchers, agencies, other management groups face the unresolved challenge of effectively detecting monitoring IAS at large spatial temporal scales. To improve detection soniferous IAS, we introduced pipeline for large-scale passive acoustic (PAM). Our main goal was illustrate how PAM can be used rapidly provide baseline information on IAS. that aim, collected data across Puerto Rico from March June 2021 single-species occupancy models investigate distribution in archipelago assess peak vocal activity. Overall, detected 16 (10 birds, 3 mammals, frogs) 79 native an extensive set with 1,773,287 1-min recordings. Avian activity peaked early morning (between 5 a.m. 7 a.m.), while amphibians between 1 Occupancy probability ranged 0.002 0.67. In general, elevation forest cover older than 54 years were negatively associated occupancy, corroborating our expectation occurrence is related high levels human disturbance present higher probabilities places characterized by more intense activities. The work presented here demonstrates workable solution vocally active over area provides reproducible workflow extended allow continued longer timeframes.

Effective management of invasive species benefits from a comprehensive understanding the species' behavior and interactions with invaded system. We investigated temporal dynamics telemetry detections potential utility traitor approach for informing response efforts to grass carp (Ctenopharyngodon idella) population in Sandusky River, major tributary Lake Erie. Telemetered exhibited heightened activity at night early morning, suggesting that capture removal be more effective during these time periods. Analysis catch per unit effort (CPUE) across different methods, trammel nets, electrofishing, hoop nets. suggested incorporating could improve capture. Low catchability values (<0.026), based on number telemetered present river weekly basis those fish captured, suggest is difficult Optimizing efficiency important refining estimates will lessen errors models interpretation low CPUE data. Results generalized additive improved using data, removals, by attempting exploratory fall winter months.

Abstract This research aims to establish the possible habitat suitability of Heracleum sosnowskyi ( HS ), one most aggressive invasive plants, in current and future climate conditions across territory European part Russia. We utilised a species distribution modelling framework using publicly available data plant occurrence collected citizen science projects CSP ). Climatic variables soil characteristics were considered follow dependencies with environmental factors. applied Random Forest classify study area. addressed problem sampling bias by optimising size implementing spatial cross-validation scheme. According model built on finally selected shape, more than half studied corresponds prediction score higher 0.25. The forecast was highly similar for all models. Almost whole showed possibility spread an average 0.4. mean temperature wettest quarter precipitation month demonstrated highest influence distribution. Thus, currently, area, excluding north, may be as s high risk spreading, while suitable locations will include latitudes. that chosen geodata pre-processing, based geospatial blocks reduced significantly bias. Obtained predictions could help assess risks accompanying invasion capturing patterns spread, can used conservation actions planning.

When origin, reproduction ability and diet define the role of birds in invasions

Proceedings of the Royal Society B Biological Sciences, Год журнала: 2023, Номер 290(1995)

The ecological impacts of invasive alien species (IAS) are increasingly documented; however, they usually studied through the lens either IAS or affected (IAS-threatened species). A clear understanding how both protagonists biological invasions characterized is still lacking. We investigated morphology, life history and ecology birds involved in invasions. Evaluating distribution 450 IAS-threatened 400 a functional space, we found that groups retained various strategies. Aliens had larger clutches were more likely to be herbivores than worldwide birds, while insular endemic from Australia region birds. showed opposite strategies aliens regarding traits related diet, origin reproduction. Further comparing associated with impact magnitude, even if mostly herbivorous, those high generalist behaviour an animal-based diet compared low impact. By emphasizing differences relating bird opened new opportunities identify role

Alien flora of Nigeria: taxonomy, biogeography, habitats, and ecological impacts

Abstract Biological invasions remain one of the greatest threats to biodiversity and livelihoods, are predicted increase due climate change globalization. In this study, we produced a comprehensive checklist alien plants in Nigeria from online flora databases, herbarium records, published field surveys, questionnaires administered botanical gardens. The resulting was classified into naturalized, invasive, cultivated plants. We then fitted random forest model identify attributes which facilitate naturalization Nigeria. also used separate chi-squared tests investigate if frequency these is significantly different between naturalized invasive results include 1,381 plant taxa, comprising 238 190 953 species.

Naturalized recorded all regions found urban agricultural landscapes. This baseline information can support further ecological studies conservation actions

Spawning site selection by invasive Asian toads (Duttaphrynus melanostictus) in eastern Madagascar

Pest Management Science, Год журнала: 2025, Номер unknown

Опубликована: Янв. 23, 2025

Abstract BACKGROUND Invasive species are a major threat to biodiversity on global scale. Control strategies for these could be improved by understanding and exploiting life history vulnerabilities. For example, most invasive anurans require waterbodies with specific characteristics spawning; therefore, modifying influence spawning success. Asian toads ( Duttaphrynus melanostictus ) were accidentally introduced the east coast of Madagascar around 2010, have since established spread across an area exceeding 850 km 2 . To determine if select sites within their invaded range, we surveyed habitat at 30 used spawning, compared adjacent, unused waterbodies, in urban rural areas eastern Madagascar. RESULTS Toads selectively oviposited small gently sloping banks, while structure surrounding vegetation, water chemistry (salinity, temperature), presence other species, depth waterbody, substrate waterbody bank did not appear site selection. CONCLUSION Our results provide pathway examine modification potential toad as management strategy pests. © 2025 Society Chemical Industry.
