Abstract In Brazil, three out four bat species from the genus Nyctinomops are known. Most of occurrences of these species are based on captures with mist-nets. In this study, we extend the distribution of Nyctinomops aurispinosus in Brazil, providing new records for the Brazilian states of Mato Grosso (1), Roraima (1), Pará (2) and Pernambuco (1). We also confirm the use of new types of shelter by N. aurispinosus, such as rock crevices in dryland environments and river boulders. We provide new fundamental information about the biology, behavioural and ecological patterns of this species.

Abstract Platyrrhinus guianensis is bat with a distribution restricted to the Guiana Region of South America in Guyana and Suriname. Herein, we report the southernmost record of this species, extending its distribution to Brazil in Brazilian Amazon. Our record indicates that the species have a larger geographical range that previously thought. Platyrrhinus guianensis occurs in sympatry with Platyrrhinus brachycephalus, Platyrrhinus incarum, and Platyrrhinus fusciventris in the Brazilian Amazon, and can be confused with these species, raising the possibility that there might be other specimens of Platyrrhinus guianensis misidentified as other species in scientific collections.

Abstract The Small Indian Mongoose Urva auropunctata (Hodgson 1836) is a small carnivore native to Iraq and South Asia; however, it has been widely introduced worldwide. The species has never been reported in Syria; however, it was suspected to occur in the extreme eastern parts of the country, but no confirmed records were made. In 2021–2022, several sightings were notified during in situ surveys in Deir ez-Zor Province in eastern Syria which confirm the first occurrence of the Small Indian Mongoose in the country.

Abstract The Yellow-throated marten Martes flavigula is one of the least studied species within the genus Martes and there is contradictory information regarding its daily activity, spanning from diurnal to nocturnal or cathemeral. Our long-term studies of the daily and seasonal activity of the Yellow-throated marten were carried out in five protected areas of Primorsky Krai (Russian Far East) using a large-scale network of camera traps from 2010 to 2021. The aim of the study was to find out the pattern of daily activity of the species, its changes over the seasons and in different territories of the region. We found that the Yellow-throated marten had a pronounced diurnal activity pattern, including one or two detection peaks per day. The species is less active at dusk and almost inactive at night in this part of its range. Two clusters with different patterns of marten activity were identified in the protected areas of Primorsky Krai: with one pronounced peak around noon in the continental part with a more severe climate and smoothed activity in coastal areas with milder climatic conditions. Seasonal detection has two peaks in April-May and October, which corresponds to species biological requirements.

Abstract Rodent-borne diseases such as bubonic plague remain a significant threat to public health in tropical countries. In plague-endemic areas, little information exists on the factors triggering periodic bursts, thus rendering preparedness strategies for preventing the negative impacts of the deadly zoonosis difficult. In this study, we assessed how species richness, diversity, and community structure of rodents are associated with plague persistence in Mbulu District, Tanzania. Rodent data were collected using the removal trapping technique. We captured 610 rodents belonging to 12 species, with Mastomys natalensis recording highest abundance. There was significantly higher abundance and species richness in persistent than non-persistent plague locality. Also, house premises recorded significantly lower species richness than farm and forest habitats. Additionally, we found three broad rodent community structures that varied significantly between studied habitat types suggesting high rodent populations interaction at fine-scale resource abundance. The high abundance and diversity of plague-susceptible rodent reservoirs suggestively contribute to the plague persistence in the foci. These results may be useful to developing preparedness strategies in these areas to control plague outbreaks.

Abstract Myotis muricola species group, being common and widespread across South-East Asia and Australasia, is highly complicated from a taxonomy point, and a combined use of different methods is required to solve subjects of its phylogeny, taxonomy and species delimitation. We try to use nuclear DNA for clarification of the taxonomic position and status of the Moluccan whiskered bat, Myotis ater , and in particular its population from mainland Asia mainland Asia. Following our results, individual nuclear markers showed weak phylogenetic signal and commonly provide controversial and low-supported topologies. The combined analysis of several nuclear genes gives a tree topology similar to the mitochondrial one, but with greatly smaller distances. Mitochondrial data, as well as morphometric data, show a separation of M. ater from M . muricola and, at the same time, a similar level of diversification between island and continental populations of M . ater . Unfortunately, nuDNA data at our disposal is not enough to come to reliable conclusions, but we may assume that continental Asia is inhabited by an undescribed taxon related to M . ater .

Abstract In Colombia, 217 bat species have been recorded of which at least 22 species occur in Andean and sub-Andean ecosystems. To evaluate the richness of bats in an Andean elevational range at the Municipality of Manizales, Central Andes of Colombia, we performed surveys supplemented with incidental captures from 2018 to 2022 at different urban and peri-urban areas, and reviewed specimens in biological collections. We evaluated the perception and knowledge that local people have about bats using an online survey. We reported 33 species in the study area. Phyllostomidae showed the highest richness (20 species), followed by Vespertilionidae (11 species), and Molossidae (2 species). For the survey, we obtained responses from 219 people who showed a good knowledge about bats and their ecological importance. We did not find significant differences between ages and levels of schooling in the perception about bats. Our results highlight the relevance of conserving the green areas of Manizales and the need for environmental education programs to reduce possible bat-human conflicts and negative perceptions. Manizales has the potential as an Area of Importance for the Conservation of Bats, due to its high bat richness and that reproduction is occurring within the study area.

Abstract The small-eared shrews Cryptotis mexicanus and Cryptotis obscurus (Eulipotyphla, Soricidae) are two closely related taxa from the northern Neotropics whose taxonomy is still unresolved. Here, we tested the hypothesis of three lineages (Northern, Central, and Southern) within this pair of semifossorial shrews. We photographed skulls, dentaries, and humeri from 226 museum specimens and used geometric morphometrics to evaluate sexual dimorphism, differences between lineages, and the effect of the environment on the shape of the structures. We found negligible differences between males and females, supporting previous studies of classical morphometrics in this genus. Our results also support the differentiation of semifossorial shrews into the three geographically isolated groups, where the size of the dentary and the shape of the three examined structures contribute to discrimination. We found a significant sign of the influence of the environment on the shape of the dentary but not on the skull or the humerus. We suggest that geographic isolation across climatically similar regions has contributed to the differentiation between lineages. We propose recognizing all three lineages as valid species that must be adequately described.

Abstract While many studies have characterized small mammals of the southern and central Great Plains (USA), far fewer have documented small mammals of the northern Great Plains which differ dramatically in plant structure and composition. We examined the presence and distribution of small mammals captured at a salinity-affected grassland in northeastern North Dakota (2018–2021). We captured 12 species from 8 genera including Microtus pennsylvanicus (n = 724), Peromyscus (maniculatus) sonoriensis (n = 114), Sorex cinereus (n = 54), and Zapus hudsonius (n = 43). We evaluated the extent to which these species varied with plant and environmental characteristics. M. pennsylvanicus was positively associated with plant cover and soil moisture and P. (maniculatus) sonoriensis was positively associated with forb cover and negatively associated with litter and elevation. Z. hudsonius was negatively associated with forb cover and soil moisture and S. cinereus was positively associated with cover and negatively associated with salinity. These species associated with their environments differently than their more southern counterparts and reinforce the notion that not all areas, even in relatively intact grasslands, are available to all species. Future studies are needed to further examine more infrequently captured species, including a Sorex hoyi, an Onychomys leucogaster, and eight Myodes gapperi in this region.

Abstract Lasiurus is a bat genus recognised to have migratory species. However, little is known about the seasonal distribution for most of its species. We used spatial analysis of occurrence records and ecological niche modeling to evaluate the seasonal distributions of five species: Lasiurus borealis, Lasiurus frantzii, Lasiurus ega, Lasiurus xanthinus, and Lasiurus intermedius, to disentangle their seasonal distribution patterns. L. intermedius, L. xanthinus, and L. frantzii presented distinct seasonal patterns in the rate of occurrence records in different areas, which accumulate most records in the northern populations in summer. For L. borealis, we found seasonal variation throughout its entire distribution, with most records in summer and a progressive decline towards winter. In contrast, L. ega showed no seasonal changes in any region. In species with seasonal changes in their occurrences records, the projections of summer conditions did not predict their preferred winter conditions, suggesting these species occupy different ecological niches seasonally. We found seasonality in the northern areas of these species’ distributions, although we could not distinguish whether migration movements or torpor behaviors are the underlying cause. Conversely, we suggest that most central and southern populations of the five species do not exhibit seasonality and are year-round residents.

Conversely, we suggest that most central and southern populations of the five species do not exhibit seasonality and are year-round residents.","PeriodicalId":49892,"journal":{"name":"Mammalia","volume":"4 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84262780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
