Ecological assessments of the effects anthropogenic change often focus on species richness or abundances. Nonetheless, changes in behavior (e.g., activity patterns) may provide equally important insights into responses to disturbance that have conservation management implications. Because many neotropical bats critical ecosystem services, their be particular concern. We evaluated season and habitat conversion temporal patterns 8 abundant frugivorous lowland tropical rain forest Iquitos,...
ABSTRACT Motivation SNAPSHOT USA is an annual, multicontributor camera trap survey of mammals across the United States. The growing dataset intended for tracking spatial and temporal responses mammal populations to changes in land use, cover climate. These data will be useful exploring drivers relative abundance distribution, as well impacts species interactions on daily activity patterns. Main Types Variables Contained 2019–2023 contains 987,979 records image sequence 9694 deployment...
Disease risk maps are important tools that help ascertain the likelihood of exposure to specific infectious agents. Understanding how climate change may affect suitability habitats for ticks will improve accuracy tick-borne pathogen transmission in humans and domestic animal populations. Lyme disease (LD) is most prevalent arthropod borne US Europe. The bacterium Borrelia burgdorferi causes LD it transmitted other mammalian hosts through bite infected Ixodes ticks. transboundary region...
Elevational gradients provide a natural experiment for assessing the extent to which structure of animal metacommunities is molded by biotic and abiotic characteristics that change gradually, or aspects plant community composition physiognomy in more discrete fashion. We used metacommunity framework integrate species‐specific responses environmental as an approach detect emergent patterns at mesoscale Luquillo Mountains Puerto Rico. Elements (coherence, species turnover range boundary...
Abstract The potential for disease transmission at the interface of wildlife, domestic animals and humans has become a major concern public health conservation biology. Research in this subject is commonly conducted local scales while regional context neglected. We argue that prevalence infection levels influenced by three mechanisms occurring landscape level metacommunity context. First, (1) dispersal, colonization, extinction pathogens, reservoir or vector hosts, nonreservoir may be due to...
Background Ornithodoros turicata is a veterinary and medically important argasid tick that recognized as vector of the relapsing fever spirochete Borrelia turicatae African swine virus. Historic collections O. have been recorded from Latin America to southern United States. However, geographic distribution this poorly understood in relation environmental variables, their hosts, consequently pathogens they transmit. Methodology Localities were generated by performing literature searches,...
Summary 1. Although time can be subdivided to promote species coexistence, quantitative examination of assemblage‐wide temporal niche overlap has seldom been explored with appropriate null models. Because the sequential and continuous nature time, it requires a different kind randomization model than those used assess subdivision discrete non‐sequential resources (e.g. food types microhabitats). 2. For two common indices (Pianka Czekanowski), we compared responses models newly developed...
Wind turbines are known to cause bat fatalities worldwide. Ultrasonic acoustic deterrents a potential solution reduce impacts on bats, but few experimental field studies have been conducted at utility scale wind energy facilities. Our objective was assess effectiveness of recently developed deterrent for reducing in southern Texas, USA. We quantified control (deterrents off) and treatment on) from 31 July through 30 October 2017 2018, assessed using generalized linear mixed models. results...
Abstract: Temporal niche partitioning can be a viable mechanism for coexistence, but has received less attention than other axes. We characterized and compared patterns of activity, overlap temporal activity among the five common rodent species from tropical semideciduous forest (TSF) between two cloud (CF) at El Cielo Biosphere Reserve in Mexico. Capture frequencies over 2-h intervals, obtained via live trapping (6850 trap-nights) chosen months 3 y formed empirical basis analyses. Trap...
The metacommunity framework integrates species-specific responses to environmental gradients detect emergent patterns of mesoscale organization. Abiotic characteristics (temperature, precipitation) and associated vegetation types change with elevation in a predictable fashion, providing opportunities decouple effects per se from those biogeographical or historical origin. Moreover, expected structure is different if along an elevational gradient molded by idiosyncratic abiotic variables...
Abstract Background The burden of leptospirosis in Puerto Rico remains unclear due to underreporting. Methods A cross-sectional survey and rodent trapping was performed a community within San Juan, determine the seroprevalence risk factors for Leptospira infection. microscopic agglutination test used detect anti-Leptospira antibodies as marker previous We evaluated carriage by quantitative polymerase chain reaction among rodents trapped at site. Results Of 202 study participants, 55 (27.2%)...
Abstract: Direct studies of mammalian carnivores are challenging due to the animals' secretive nature and high costs associated with their capture handling. Use noninvasive hair sampling survey these reclusive species has great potential as an alternative, wide applicability in ecology conservation. Hair‐trapping been extensively used for focal temperate mammals, but its use a means mammals tropical environs never addressed. We evaluated effectiveness 2 hair‐trap types scents along...
High species diversity of the potential animal host community for a zoonotic pathogen may reduce transmission among most competent host, phenomenon called "dilution effect", but mechanisms driving this effect have been little studied. One proposed mechanism is "encounter reduction" where low-competency decrease contact rates between infected and susceptible hosts, especially in directly transmitted diseases. We conducted an experiment outdoor enclosures northwestern Mexico we manipulated...
Incidences of atypical color patterns in otters are scarce, particularly for the Neotropical otter (Lontra longicaudis annectens). We report three L. l. annectens individuals, one with partial and two total leucism; first is from Río Temascaltepec, state México, other Mante, Tamaulipas, México. Because causes that induce this genetic alteration poorly understood, possible factors might phenotypic abnormality adverse effects on populations discussed.
Leptospirosis, an emerging infectious disease caused by bacteria of the genus Leptospira, is thought to be most widespread zoonotic in world. A first step preventing spread Leptospira delineating animal reservoirs that maintain and disperse bacteria. Quantitative PCR (qPCR) methods targeting LipL32 gene were used analyze kidney samples from 124 House mice (Mus musculus), 94 Black rats (Rattus rattus), 5 Norway (R. norvegicus), 89 small Indian mongooses (Herpestes auropunctatus) five cattle...
