ResumenEl margay (Leopardus wiedii) y el yaguarundi (Herpailurus yagouaroundi) son felinos medianos neotropicales de los cuales existen pocos estudios en Guatemala. Ambas especies se conocen principalmente por observaciones esporádicas y en rara ocasión son referenciadas geográficamente. En este trabajo reportamos la presencia de margay y yaguarundi en la Reserva Natural Ranchitos del Quetzal, Purulhá, Baja Verapaz. Nuestras observaciones se basan en registros de cámaras trampa colocadas en un parche de bosque nuboso entre 1,600 y 1,900 msnm durante 2017 y 2019. Registramos la presencia de yaguarundi a 31 km al sureste del sitio reportado más cercano, lo que extendió su área de distribución en Guatemala. Adicionalmente, confirmamos la presencia de margay a más de 1,500 msnm en bosque nuboso de Baja Verapaz, lo cual extendió su área de distribución 30 km al sureste del sitio reportado más cercano en Guatemala.Palabras clave: cámaras trampa, distribución, Guatemala, mamíferos, margay, yaguarundi.AbstractThe margay (Leopardus wiedii) and jaguarundi (Herpailurus yagouaroundi) are medium-sized neotropical felines for which few studies have been conducted in Guatemala. Both species are mainly known from sporadic observations and are rarely geographically referenced. We report the presence of margay and jaguarundi in the Private Natural Reserve Ranchitos del Quetzal, Purulhá, Baja Verapaz, Guatemala. We base our records on observations using camera traps placed in a cloud forest between 1,600 and 1,900 mamsl during 2017 and 2019. We recorded the presence of jaguarundi 31 km SE of the closest registered site, increasing its reported distribution area in Guatemala. Additionally, we report the presence of margay over 1,500 mamsl in the cloud forest of Baja Verapaz, which increases its distribution by 30 km SE of the closest registered site in Guatemala up to date.Key words: camera traps, distribution, Guatemala, jaguarundi, mammals, margay.

Ecosystems in the northern Andes face unprecedented habitat loss. Pumas are the top predators in the region and exert key ecological functions, such as population control and resource facilitation. However, little is known about the temporal niche of the species or its effects on behaviour of prey in the tropics. We hypothesized that there is a link between the activity patterns of pumas and their prey in a cloud forest of the Central Andes of Colombia. We installed 61 camera traps to estimate the degree of overlap between the daily activity curves of pumas and seven potential prey species, using conditional kernel density functions. Pumas, armadillos, mountain pacas, and white–eared opossums were mainly nocturnal, with little crepuscular activity and high temporal overlap. Central American agouti, mountain coati, little red brocket deer, and Cauca guan displayed a predominantly diurnal activity and temporal partitioning with pumas. As opportunistic predators, pumas were able to maximize foraging efficiency by preying on the crepuscular and nocturnal species. Conservation of this highland predator will largely depend on the suitable management of its native prey.

SummaryDelimiting the distribution of a species is a complex task because many determining factors are difficult to assess in the field. This is important because distribution is a key factor in the decision-making process for conservation. One example is the Bearded Wood Partridge Dendrortyx barbatus, a species endemic to the temperate forests of the Sierra Madre Oriental (SMO) mountain range in Mexico. Lack of knowledge of its distribution has generated confusion over the assignment of the correct risk category. With the aim of predicting the distribution area of the Bearded Wood Partridge and contributing to strategies for its conservation, we updated and extended the knowledge of its distribution by modelling its ecological niche using GARP and MaxEnt algorithms. We also analysed its environmental distribution using principal components analysis, and contrasted the two most important environmental variables with the species’s distribution based on vegetation type. We found that the area potentially occupied by this species covers 17,956 km2 according to GARP and 12,974 km2 according to MaxEnt. We suggest that there is a biogeographic barrier which limits the distribution of this species in the southern part of its range. The abiotic variables that best explain its distribution are average annual precipitation and elevation, both of which coincide well with the distribution of cloud forest. A redefinition of the current range as recognised by IUCN is proposed along with the need to change its national risk category.

AbstractThe Pampas cat Leopardus colocolo occurs in a variety of habitats from northern Ecuador to southern Argentina, yet the species has been poorly studied. There is scant information about its northern distribution or about populations in desert and dry forest. We aimed to determine the presence of the Pampas cat in the Sechura Desert and seasonally dry forest of north-western Peru and south-western Ecuador, identify threats to the species, and describe people's perceptions of it. Using 32 camera traps and compiling confirmed and unpublished records, we mapped the species’ distribution and identified 12 new localities, three in the Sechura Desert and nine in the dry forest. The first records of the Pampas cat in the Ecuadorian dry forest are reported from La Ceiba Natural Reserve and Jorupe Reserve; the northernmost record in the dry forest is from Cerros de Amotape National Park, Peru. In 56 semi-structured interviews with local people we found that most of them (76.8%) did not know the species; 61.5% of those who knew the species had a neutral perception and did not think the cat affected their personal activities. Here we update the northern distribution of the Pampas cat, describe threats to the species in arid ecosystems, and highlight the need for further studies to identify other possible threats and mitigation methods.

The East Asian tree Ulmus japonica (Rehder) Sarg. is a nemoral relict species for Western Transbaikalia (See Fig. 1). A few localities of this tree are known in the region, those in the lower reaches of the Selenga River (Yugovo site; Republic of Buryatia) and the Chikoy River (Zhindo site; Zabaikalskii Krai), remote from the main distribution area (See Fig. 2). The study aimed to verify the distribution of U. japonica and to estimate the value of U. japonica communities for biodiversity conservation in the region. Based on the data collected, we discussed some opportunities and suggested approaches for the protection of these unique ecosystems. During the fieldwork in 2018 and 2019, we studied all known localities of U. japonica in Western Transbaikalia and revealed a pleiad of new locations within the site Yugovo as well as a new location (the site Murochi) in the Chikoy River valley within the Republic of Buryatia (See Fig. 2 and 3). Information on the occurrence of U. japonica in the vicinity of Podlopatki village (in the Khilok River valley) was not confirmed. Also, our attempts to find this species at the site within the Barguzin River valley according to the label of the existing herbarium specimen failed. Based on 93 relevés, we examined species composition in woodlands where U. japonica is a codominant species and revealed the main features and peculiarities of the communities in the region. At all sites, monodominant coppices of U. japonica and coenoses where it is mixed with Padus avium Mill. occurred. Nevertheless, Ulmus japonica communities from the site Yugovo differ from those of Zhindo and Murochi in a greater phytocoenotic diversity and the composition of characteristic plant species. Additionally, at Yugovo rather xeromesophytic sparse communities where U. japonica is mixed with Pinus sylvestris L. and Betula platyphylla Sukaczev were found. Characteristic species of shrub and herbal layers at Yugovo site are Carex arnellii Christ ex Scheutz, Circaea lutetiana L., Elymus pendulinus (Nevski) Tzvelev, Festuca extremiorientalis Ohwi, Filipendula palmata (Pall.) Maxim., Hesperis sibirica L., Lamium album subsp. orientale Kamelin & A.L. Budantzev, whereas at Zhindo and Murochi they are Anemonidium dichotomum (L.) Holub, Carex sordida Van Heurck & Müll. Arg, Menispermum dauricum DC., Rhamnus davurica Pall., and Rubia cordifolia L. According to our studies supplemented with data from the literature sources, there are 16 species of vascular plants, lichens, beetles, and lepidopterans registered in Ulmus japonicaforests that are included in the Federal and/or in regional Red Data Books (See Table 1). We have revealed 31 additional rare and relict species of plants, fungi and insects (See Table 2). In total, 19 species were found in Western Transbaikalia or within this plant community type for the first time. The newly revealed rare and relict species could be recommended for listing in the regional Red Data Book or inclusion in the list of species of special surveillance. As a perspective of the protection of communities with U. japonica, we propose to maintain them as distinct clusters under the management of the existing protected areas. Namely, the site Yugovo can be protected as a separate cluster of the Baikal Natural Reserve, likewise, the protection of the site Zhindo can be managed by the Chikoy National Park. The newly discovered site Murochi might be included in the preliminarily proposed Russian-Mongolian trans-boundary Selenga protected area.

Interspecific interactions among tropical mesocarnivorous species and other mammalian trophic guilds have been poorly studied, despite they have important implications in the survival, structure, demography, and distribution of these species. In this study we analyzed spatio-temporal interactions of three sympatric mesocarnivores that are located in the Northeastern limit of their geographic distribution in Mexico, with the objective of analyzing if these species coexist or compete in the axis of the temporal and spatial niche. With a sampling period from January 2015 to December 2016 and 26 camera-trapping stations (with in a set of two camera traps opposite to each other) and located along roads and animal trails, we determined the activity pattern and habitat use of L. wiedii (margay), L. pardalis (ocelote) y P. yagouaroundi (yaguarundi). All independent photographs of each species were grouped into three temporal categories (day, night and twilight) and six habitat categories; Oak Forest, Oak-Pine Forest, Cloud Forest, Pine-Oak Forest, Tropical Deciduous Forest and Medium Forest. Temporal and spatial overlap between species (i.e interactions) was obtained with the Czekanowski index and the Pianka index, respectively. These indices are symmetrical and take values from zero to one, where the results close to zero indicate that there is no overlap between species and values close to one indicate overlap. We obtained a total of 379 independent photographs, of which 239 corresponded to margay, 118 to ocelot and 22 to yaguarundi. Margay and ocelot were nocturnal, with 75 % of their records in this category showing a high temporal overlap (0.85); whereas yaguarundi was fully diurnal, suggesting it may be able to coexist with the other two species (margay and ocelot). Moreover, the yaguarundi used habitat similar to ocelot and margay (with high spatial overlap of 0.81 and 0.72, respectively), while the spatial overlap between the margay and ocelot was intermediate (0.53), since they used in most cases different habitat types. Our results suggest that there is no interspecific competition among these tropical mesocarnivorous species, probably due to antagonistic interactions among them on the temporal and spatial axis. These strategies may positively favor populations of mesocarnivores, which are characterized by having a high territorial behavior.

Quimsacocha National Recreation Area is located on the western slope of the Andes in Azuay Province, southern Ecuador. All sampling locations were in the high paramo and high Andean forests (3,572 to 3,865 m). The habitats include paramo, bogs, riparian, patches of elfin forests, and secondary cloud forest. We set Sherman, pitfall, and camera traps (3,600 trap nights), and mist nets to collect 117 specimens. Eight species were collected, including Caenolestes caniventer Anthony 1921; Didelphis pernigra J.A. Allen, 1900; Cryptotis montivagus (Anthony, 1921); Akodon mollis Thomas, 1894; Microryzomys altissimus (Osgood, 1933), Phyllotis haggardi Thomas, 1908; Sigmodon inopinatus Anthony, 1924; and Sylvilagus andinus (Thomas, 1897). Two additional species Coendou rufescens (Gray, 1865) and Odocoileus virginianus (Zimmermann, 1780) were documented photographically. This is the first survey that saved voucher specimens for mammals of Quimsacocha.

AbstractRemaining jaguar Panthera onca populations in the Atlantic Forest are restricted to eight regions, and all populations appear to be declining. We report on the status of one of the last populations in south-eastern Brazil. We monitored this population with camera traps during June 2005–January 2013 in Vale Natural Reserve. We estimated an abundance of 9 ± SE 1.98 jaguars (95% CI 9–17) and a population density of 3.22 ± SE 1.58 individuals per 100 km2 (95% CI 1.29–7.98). Annual survival probability over a 5-year interval was 78% (95% CI 58–98) and the recapture probability was 62% (95% CI 42–79). Although our results are among the highest densities reported for the jaguar in this biome, the future of the population is threatened by genetic deterioration and local threats, including the expansion of an existing highway and depletion of the jaguar's native prey base as a result of poaching, and will depend upon urgent implementation of conservation actions. The necessary actions include establishing gene flow with other compatible populations, increasing surveillance against poaching, continuing population monitoring of jaguars and their main prey species, and implementing mitigation measures in relation to the impacts of the highway on local fauna.

ResumenSe modeló la distribución potencial del tapir en Honduras, utilizando el programa MaxEnt. Se identificaron las áreas de idoneidad con base en la correlación de los registros de la presencia de la especie y 19 variables climáticas. Los resultados predicen un área aproximada para Honduras de 19,751 km2, lo que representa el 17.55% del territorio hondureño. Se obtuvo un auc de 0.933 y se mostraron valores de 0.32 a 1 en la distribución potencial del tapir. El territorio de la especie se limita a los bosques nublados del caribe hondureño, a una pequeña porción del centro montañoso de Honduras, así como la región de la Moskitia. El hábitat de la distribución del tapir se encuentra fragmentado y aislado, dominado principalmente por paisajes agrícolas. Así mismo el tapir se encuentra amenazado por la presión de cacería y la pérdida de su hábitat por deforestación. De no implementar mayores esfuerzos en la conservación del tapir, esta especie está destinada a extirparse en gran parte de su rango de distribución en Honduras.Palabras clave: distribución potencial, extinción local, idoneidad, MaxEnt.AbstractPotential distribution for tapir in Honduras was modeled using the MaxEnt program. Suitable areas were identified for tapir, correlated and based on records of the presence of the species and 19 climatic variables. The results predicted a potential distribution area in Honduras of 19,751 km2 representing 17.55% of Honduran territory; showing an auc of 0.993 and values from 0.32 to 1 in the potential distribution of the tapir. The tapir territory is represented in the Caribbean by cloud forest and a few high lands in the central east of Honduras and the Moskitia region. The habitat of the tapir is fragmented and isolated, dominated by agricultural landscapes. The tapir is threatened by hunting pressure and habitat loss due to deforestation. If conservation efforts are not improved, this specie will disappear from its distribution range in Honduras.Key words: potential distribution, local extinction, adequacy, MaxEnt.

Floodplain valley of the Dnieper river midstream is a unique natural complex, having a great bìogeographical, ecological, environmental, historical and recreational values. In 1990, the Natural reserve «Dniprovsko-Orilsky» was established within the area. The Natural reserve «Dniprovsko-Orilsky» is environmentally protected site within the Dnipropetrovsk region, Dnipropetrovsk oblast, Ukraine. This reserve occupies part of the Dnieper river valley and marshy and reedy banks of Protovch river (existing bed of Oril river). It was created by Regulation of the Council of Ministers of the USSR of 15 September 1990, No. 262, based on common zoological and ornitological Nature reserves «Taromskì plavni» and «Obukhovskie zaplavy». On the territory of the Natural reserve «Dniprovsko-Orilsky», they were registered 32 Lepidoptera species listed in the List of Threatened Species at different categories (5 species in IUCN Red List ; 18 in Red Data Book of Ukraine; 7 in European Red List of plants and animals endangered on a global scale; 31 in Red Book of Dnipropetrovsk oblast). The main scientific materials were author’s collections from area of research and materials of entomological funds, Department of Zoology and Ecology, Oles Honchar Dnipropetrovsk National University (mostly Memorial Collection of V. O. Barsov). Field surveys covered all the ecosystems basic on size and degree of protection. The author’s researches have conducted over the past decade during annual expeditions to the Reserve. Taxonomic structure of the complex is quite diverse, and represented by all the major families of higher millers and rhopalocera, having protectedstatus. In relation to taxonomy, this complex formed by representatives of five superfamilies (Zyganoidea, Noctuoidea, Bombycoidea, Hesperioidea, Papilionoidea) from 11 families (Zygaenidae, Saturniidae, Sphingidae, Noctuidae Arctiidae Hesperiidae, Papilionidae, Pieridae, Nymphalidae, Satyridae, Lycaenidae). High taxonomic diversity can be explained by unique geographical location of the reserve in azonal conditions of the Dnieper river valley. Such location allows to enter different zoogeographic Lepidoptera groups on the reserve territory. Zoogeographic analysis of species protected within the reserve territory selected 7 basic groups. It was found that most of the globally rare species have Mediterranean origin (39 %); species of Palearctic origin are in second place (22 %); Western Palearctic and Ponto-Kazakh types of areas are same of number of species, and come third (11 %); and others come 17 % (European, Euro-Siberian, and Holarctic). This fauna component is specific due to presence of so-called «northern» species that make up 40 % (representatives of Palearctic, Western Palearctic, Euro-Siberian, European and Holarctic groups). Their existence within the reserve territory is only possible due to development of boreal valley ecosystems.

Abstract A part of the COI mitochondrial barcoding gene was sequenced from seven species of different taxonomical groups: Ambystoma mexicanum (Amphibia, Ambystomatidae), Darevskia lindholmi, Lacerta agilis exigua (Reptilia, Lacertidae), Erinaceus roumanicus (Mammalia, Erinaceidae), Macrobiotus sp. 1 and 2 (Eutardigrada, Macrobiotidae) and Cameraria ohridella (Insecta, Gracillariidae). The sequences were compared with available sequences from databases and positioned on phylogenetic trees when the taxa had not yet been sequenced. The presence of Mexican axolotls in herpetoculture in Ukraine was confirmed. The partial COI genes of the Crimean rock lizard and an eastern sub-species of the sand lizard were sequenced. We demonstrated the presence of two tardigrade mitochondrial lineages of the Macrobiotus hufelandi group in the same sample from the Zeya Natural Reserve in the Far East: one was nearly identical to the Italian M. macrocalix, and the other one is similar to M. persimilis and M. vladimiri. We also confirmed the presence of the invasive haplotype “A” of the horse chestnut leaf miner in Ukraine, in line with the hypothesized route of invasion from Central Europe.
