“…These data show that a conservation problem probably exists for many preys and mesocarnivore species due to the high abundance of feral and free‐ranging dogs in many areas worldwide. This threat is receiving much attention with the increase in scientific knowledge on the adverse effects of feral and free‐ranging dogs on native species (Callan et al., 2020; Carrasco‐Román et al., 2021; Doherty et al., 2017; Martínez‐Sotelo et al., 2022; Wierzbowska et al., 2016; Zapata‐Ríos & Branch, 2016). However, despite this increasing evidence of the adverse effects of free‐ranging dogs on biodiversity, there is a lack of management actions to reduce its effects.…”

“…Feral and free‐ranging dogs pose a severe threat to wildlife, especially carnivore species that may share diseases or prey species (Butler et al., 2004; Martínez‐Sotelo et al., 2022; Nayeri et al., 2021; Randall et al., 2006; Young et al., 2011). Here, we show a high risk of predation by feral and free‐ranging dogs on the three squirrels species studied in different ecosystems, so this should be considered in areas with a high abundance of free‐ranging dogs and the presence of threatened species.…”

“…Feral and free‐ranging dogs can have critical ecological impacts on wildlife and receive increasing attention from researchers and conservationists (Bryce, 2021; Doherty et al., 2017; Ritchie et al., 2014; Zapata‐Ríos & Branch, 2018). Feral and free‐ranging dogs pose a threat to many species of wildlife due to direct predation (Carrasco‐Román et al., 2021; Doherty et al., 2017; Nayeri et al., 2021; Young et al., 2011), harass wildlife (Young et al., 2011), disease transmission (Butler et al., 2004; Martínez‐Sotelo et al., 2022; Randall et al., 2006), resources competition (Tobajas, Descalzo, Ferreras, et al., 2021; Wierzbowska et al., 2016) or limiting the spatiotemporal use of wildlife (Callan et al., 2020; Carvalho et al., 2019; Lenth et al., 2008). However, effects on the activity patterns of wildlife have not received as much attention in the scientific literature (see Pérez‐Irineo et al., 2021; Zapata‐Ríos & Branch, 2016), especially on small prey species (see Caravaggi et al., 2018; Mori et al., 2021; Viviano et al., 2021).…”

Small mammals show variations in activity patterns due to the use of resources and the risk of predation. However, in the case of tree squirrel species, the factors that affect their activity patterns are poorly studied. We used camera trapping to investigate the activity patterns of three different squirrel species of the genus Sciurus, two species of squirrel (Sciurus aureogaster and S. oculatus) from Mexico and one from the Iberian Peninsula (S. vulgaris). In addition, we compared their activity patterns with the potential predator community and their most important predators (Mexico: gray fox Urocyon cinereoargenteus, ringtail Bassariscus astutus, Opossum Didelphis virginiana; Spain: red fox Vulpes vulpes, pine and stone marten Martes spp.), and with feral and free-ranging dogs (Canis lupus familiaris). We evaluated the predation risk by the carnivore community on the squirrels when they descend to the ground by studying their temporal overlap and observing if the squirrels have different activity patterns adjusted to the carnivore community in each study area. The results showed that the three species of squirrels consistently descended to the ground during the day, showing a variable maximum peak of activity between 8:00 and 12:00 h. Temporal overlap of activity patterns of the three species with the carnivore community was low (D = 0.12-0.36), same as with the main predators (Mexico: gray fox D = 0.14-0.21, ringtail D = 0.08-0.09, opossum D = 0.06-0.07; Spain: red fox D = 0.39, martens D = 0.22). However, temporal overlap of activity patterns with the domestic dog was moderate-high in the three squirrel species (Mexico D = 0.55-0.88, Spain D = 0.79). These results show that the species of the genus Sciurus have adjusted their activity patterns of ground use to reduce predation risk by wild predators but not with feral and free-ranging dogs, something which can pose a serious conservation problem for these species.

Insectivores (Eulypotiphla) are a substantial component of Russian forest ecosystems. The parasites of these animals also form an important part of natural biocenoses and act as one of the factors in the formation of biodiversity. The Mordovia Nature Reserve and National Park “Smolny” are large, forested areas located in the center of European Russia. We studied the helminth fauna of insectivores in these protected areas in 2018–2022. In total, using the method of complete helminthological necropsy, we examined 478 individuals of shrews, moles, and hedgehogs and recorded 34 species of parasitic worms, i.e., 8 trematode, 7 cestode, 1 acanthocephalan, and 18 nematode species. The most diverse helminth fauna was found in Sorex araneus (22 species). The composition of helminths in S. isodon (12), Neomys fodiens (9), Sorex minutus, and Erinaceus roumanicus (8 species each) turned out to be less diverse. The lowest species diversity of helminths was observed in Neomys milleri (3) and Talpae europaea (2 species). Taking into account the newly obtained data, we conducted a review of the helminth diversity in shrews, hedgehogs, and moles in the Middle Volga region. According to our literature data, the helminth fauna of insectivores in this region consists of 52 species, including 14 cestodes, 13 trematodes, 22 nematodes, and 3 acanthocephalans. Most of them belong to the Palearctic faunal complex (36 species). The helminth fauna of insectivores in the studied protected areas was compared with the helminth fauna of micromammals in other areas of the Middle Volga region. Our comparative analysis showed a high and average degree of similarity in the helminth fauna within individual species and genera of Eulipotyphla.

“…Gastrointestinal nematodes are known to be agents that can potentially interfere with animal health and the general welfare of society in various parts of the world. Gastrointestinal nematode infection is a significant obstacle in animal health and public health (Beugnet et al 2014;de Mello et al 2022;Martínez-Sotelo et al 2022;Nath et al 2022;Tadege et al 2022;Nath et al 2023). Cats (Felis catus Linnaeus, 1758) from private households, kennels, and feral cats can be infected by gastrointestinal nematodes, i.e.…”

Abstract. Widiyono I, Rusmihayati, Purnamaningsih H, Sahara A. 2023. Zoonotic gastrointestinal nematodes in pet cats in Yogyakarta (Indonesia) and their susceptibility to anthelmintics. Biodiversitas 24: 3332-3337. Domestic cats (Felis catus Linnaeus, 1758), which live close to humans, can host some zoonotic nematodes. Therefore, a study on gastrointestinal nematodes in domestic cats and their anthelmintic resistance is essential for controlling and preventing zoonotic nematodiasis. Our goal was to investigate the diversity of gastrointestinal nematodes in pet cats in Yogyakarta and their susceptibility to anthelmintics. One hundred seventy-four (174) out of 215 cat patients (80.93%) presented at the animal clinic of the Department of Internal Medicine, Faculty of Veterinary Medicine, Universitas Gadjah Mada, Yogyakarta, Indonesia, and suspected gastrointestinal parasite infections suffered from nematodiasis. Ninety-eight (98) animals suffering from moderate to severe gastrointestinal nematodiasis with Egg Per Gram feces (EPG) >300 were included into nematode identification, clinical analyses, and evaluation of nematode susceptibility to anthelmintics. The animals were divided in three treatment groups, namely pyrantel pamoate at the dose of 5 mg/kg BW orally on D0 (OP), subcutaneous injection of ivermectin at the dose of 200 µg/kg BW on day 0 (SCI), and no medication as a Control (C). Fecal samples were collected on day 0 and 10 for parasitological examinations. The results showed that pet cats were infected with Toxocara sp. and Ancylostoma sp., with the incidence of single infection by Toxocara sp., Ancylostoma sp., and mixed infection at 50%, 36.73%, and 13.27%, respectively. The animals were clinically healthy or showing clinical signs, e.g., anorexia, diarrhea, vomiting, and dull hair. Pyrantel pamoate and ivermectin showed >98% efficacy against these nematodes. In conclusion, there were two zoonotic gastrointestinal nematodes in pet cats in Yogyakarta, namely Ancylostoma and Toxocara, which still showed high susceptibility to pyrantel pamoate and ivermectin.
