Mamíferos de Médio e Grande Porte de Uma RPPN No Município de Jaú, Estado de São Paulo

The medium to large-sized mammals make population control of invertebrates and vertebrates, as well as seed dispersers are also important. Are losing territory and living area because of deforestation and fragmentation of natural areas, mainly in the Atlantic Forest. The RPPN Amadeu Botelho, in the municipality of Jaú, São Paulo State, is one of the last forest remnants of interior paulista. It is isolated from other forest fragments and thus is a wildlife refuge in the region of Jaú, Midwest of the State. Animals as Pumas (Puma concolor), ocelot (Leopardus pardalis), cat-Moorish (Puma yagouaroundi), have already been sighted in the reserve by officials and residents. The buffer property of the farm Santo Antônio dos Ipês, is surrounded by several plantations, and is very close to the Centre of the city of Jaú. In addition to the lifting of the reservation, it sized mammal species diagnosed the influences that the activities of the farm and the proximity to the Centre of the municipality of Jaú exert to fauna studied

Levantamento da mastofauna terrestre de médio e grande porte ao longo da Rodovia Alcides Soares, Botucatu-SP, como subsídio para ações de conservação

Atropelamentos associados à fragmentação dos habitats naturais, tanto para construção de estradas, quanto para agricultura, são uma das principais causas de mortalidade para várias espécies de animais silvestres pelo mundo todo. Durante o período de agosto de 2011 e junho de 2012, em um trecho da Estrada Vicinal Alcides Rodrigues Soares do município de Botucatu, interior do estado de SP, foi realizado o levantamento de mamíferos terrestres de médio e grande porte através do método de parcelas de areia e transecto, além da procura de carcaça de animais atropelados. Espécies como Onça-parda (Puma concolor) e Tamanduá-bandeira (Myrmecophaga tridactyla), ambas em situação vulnerável de extinção, foram registradas em proximidade da estrada. Através dos dados obtidos, tem se como objetivo demonstrar a importância da valorização da fauna local, com a construção de passagens de fauna, como uma das medidas para a sua conservação e consequente redução dos diversos distúrbios e impactos causados por estradas

Medium and large-sized mammals in a private reserve of natural heritage in the municipality of Jaú, São Paulo, Brazil

Medium and large-sized mammals control invertebrate and vertebrate populations and are important seed dispersers. These animals are losing their territory and living range due to deforestation and the fragmentation of natural areas, particularly in the Atlantic Forest and Cerrado. The Private Reserve of Natural Heritage (PRNH) Amadeu Botelho is isolated from other forest fragments and is thus a wildlife refuge in the region of Jaú, central-western region of state of São Paulo, southeastem Brazil. Animals as such as the puma (Puma concolor), ocelot (Leopardus pardalis) and jaguarundi (Puma yagouaroundi) have been sighted in the reserve by wildlife guards and residents. This reserve, which belongs to “Santo Antônio dos Ipês” farm, is surrounded by several plantations, and is very close to the center of the city of Jaú. In addition to surveying the mammal species in the reserve, this study diagnosed the influence of the farm’s activities and the proximity to the center of the municipality of Jaú on the fauna under study

Predator and Heterospecific Stimuli Alter Behavior in Cattle

Wild and domestic ungulates modify their behavior in the presence of olfactory and visual cues of predators but investigations have not exposed a domestic species to a series of cues representing various predators and other ungulate herbivores.We used wolf (Canis lupus), mountain lion (Puma concolor), and mule deer (Odocoileus hemionus) stimuli (olfactory and visual), and a control (no stimuli) to experimentally test for differences in behavior of cattle (Bos taurus) raised in Arizona. We measured (1) vigilance, (2) foraging rates, (3) giving up density (GUD) of high quality foods and (4) time spent in high quality forage locations in response to location of stimuli treatments. In general, we found a consistent pattern in that wolf and deer treatments caused disparate results in all 4 response variables. Wolf stimuli significantly increased cattle vigilance and decreased cattle foraging rates; conversely, deer stimuli significantly increased cattle foraging rate and increased cattle use of high quality forage areas containing stimuli. Mountain lion stimuli did not significantly impact any of the 4 response variables. Our findings suggest that domestic herbivores react to predatory stimuli, can differentiate between stimuli representing two predatory species, and suggest that cattle may reduce antipredatory behaviour when near heterospecifics.

Using occupancy models to investigate space partitioning between two sympatric large predators, the jaguar and puma in central Brazil

Coexistence of sympatric species is mediated by resource partitioning. Pumas occur sympatrically with jaguars throughout most of the jaguar's range but few studies have investigated space partitioning between both species. Here, camera trapping and occupancy models accounting for imperfect detection were employed in a Bayesian framework to investigate space partitioning between the jaguar and puma in Emas National Park (ENP), central Brazil. Jaguars were estimated to occupy 54.1% and pumas 39.3% of the sample sites. Jaguar occupancy was negatively correlated with distance to water and positively correlated with the amount of dense habitat surrounding the camera trap. Puma occupancy only showed a weak negative correlation with distance to water and with jaguar presence. Both species were less often present at the same site than expected under independent distributions. Jaguars had a significantly higher detection probability at cameras on roads than at off-road locations. For pumas, detection was similar on and off-road. Results indicate that both differences in habitat use and active avoidance shape space partitioning between jaguars and pumas in ENP. Considering its size, the jaguar is likely the competitively dominant of the two species. Owing to its habitat preferences, suitable jaguar habitat outside the park is probably sparse. Consequently, the jaguar population is likely largely confined to the park, while the puma population is known to extend into ENP's surroundings. (C) 2011 Deutsche Gesellschaft fur Saugetierkunde.

High Proportion of Male Faeces in Jaguar Populations

Faeces provide relevant biological information which includes, with the application of genetic techniques, the sex and identity of individuals that defecated, thus providing potentially useful data on the behaviour and ecology of individuals, as well as the dynamics and structure of populations. This paper presents estimates of the sex ratio of different felid species (jaguar, Panthera onca; puma, Puma concolor; and ocelot/margay, Leopardus pardalis/Leopardus wiedi) as observed in field collected faeces, and proposes several hypotheses that could explain the strikingly high proportion of faeces from male jaguars. The proportion of male and female faeces was estimated using a non-invasive faecal sampling method in 14 study areas in Mexico and Brazil. Faecal samples were genetically analysed to identify the species, the sex and the individual (the latter only for samples identified as belonging to jaguars). Considering the three species, 72.6% of faeces (n = 493) were from males; however, there were significant differences among them, with the proportion from males being higher for jaguars than for pumas and ocelots/margays. A male-bias was consistently observed in all study areas for jaguar faeces, but not for the other species. For jaguars the trend was the same when considering the number of individuals identified (n = 68), with an average of 4.2 +/- 0.56 faeces per male and 2.0 +/- 0.36 per female. The observed faecal marking patterns might be related to the behaviour of female jaguars directed toward protecting litters from males, and in both male and female pumas, to prevent interspecific aggressions from male jaguars. The hypothesis that there are effectively more males than females in jaguar populations cannot be discarded, which could be due to the fact that females are territorial and males are not, or a tendency for males to disperse into suboptimal areas for the species.

Flut und Hitze: Auswirkungen extremer Klimaereignisse auf die epigäische Arthropodenfauna (Araneae – Spinnen) ufernaher Lebensräume (Auen, Polder) des Inselrheins bei Mainz

Die vorliegende Arbeit ist ein Teil des Projektes Flut und Hitze des Kompetenzzentrums Überflutung an der Universität Mainz. Die Ziele dieser Untersuchung waren: Die Artzusammensetzung und Phänologien der Spinnengemeinschaften von Uferhabitaten bei Mainz (Rheinland-Pfalz, Deutschland) zu ermitteln, anhand des Artenspektrums die Folgen langjähriger Trockenheit und die Auswirkungen des Extremsommers 2003 zu beschreiben, Einflüsse von Überflutungen festzustellen und die Submersionstoleranzen ausgewählter Arten zu bestimmen. Insgesamt wurden 27783 Spinnen aus 179 Arten und 24 Familien bearbeitet. Die Untersuchung umfasste einen Hartholzauwald bei Ingelheim am Rhein, den Hochwasserschutzpolder Ingelheim, sowie Tiermaterial von vier weiteren Uferstandorten und drei Inselstandorten des Rheins bei Mainz. Die Beprobung der Hartholzaue mit Barberfallen und Stammeklektoren erfolgte von Mai 2005 bis Mai 2008. Im Polder wurden von Oktober 2006 bis Mai 2008 mit Barberfallen und einem Vakuumsauger gefangen. Die Proben der weiteren Standorte stammten aus Barberfallenfängen der Jahre 2000 bis einschließlich 2005. In der seit Winter 2002/2003 nicht mehr überfluteten und im Sommer stark austrocknenden Hartholzaue wurde eine als xerotolerant zu bezeichnende Spinnenfauna vorgefunden. Dies galt insbesondere für die sehr artenreiche Stammregion. Zu den dominierenden Spezies zählten: Diplostyla concolor (Boden), Clubiona pallidula und Textrix denticulata (beide Stamm). Der Polder Ingelheim wurde überwiegend von euryöken Freilandbewohnern besiedelt, dominant kamen Oedothorax apicatus und Pardosa agrestis vor. Das Tiermaterial der Ufer- und Inselstandorte wies deutliche Unterschiede in der Artenzusammensetzung im Bezug auf die Flutungsintensität auf. Nach dem Ausbleiben von Hochwässern und dem starken Austrocknen der Standorte im Sommer 2003 wurden hygrobionte Arten wie Allomengea vidua kaum mehr vorgefunden, während sich xerotolerante Spezies ausbreiteten. Darüber hinaus wurden die Submersionstoleranzen ausgewählter Spinnenarten im Labor ermittelt. Die gewonnenen Daten lassen Vermuten, dass die getesteten Spinnenspezies durchaus in der Lage sind, bei niedrigen Wassertemperaturen eine kurze Flut submers zu überstehen. Unter hohen Temperaturen besteht dagegen keine Submersionstoleranz.

Determination of ages and fossil Coleoptera fauna from eight sites in the London region

These data sets report the fossil beetle assemblages identified from the Mesolithic to Late Bronze Age at eight sites in the London region. All but one of the study sites are within 2 km of the modern course of the Thames. The sites produced 128 faunal assemblages that yielded 218 identified species in 41 families of Coleoptera (beetles).  Beetle faunas of Mesolithic age indicate extensive wetlands near the Thames, bordered by rich deciduous woodlands. The proportion of woodland species declined in the Neolithic, apparently because of the expansion of wetlands, rather than because of human activities. The Early Bronze Age faunas contained a greater proportion of coniferous woodland and aquatic (standing water) species. An increase in the dung beetle fauna indicates the presence of sheep, cattle and horses, and various beetles associated with crop lands demonstrate the local rise of agriculture, albeit several centuries after the beginnings of farming in other regions of Britain. Late Bronze Age faunas show the continued development of agriculture and animal husbandry along the lower Thames. About 33% of the total identified beetle fauna from the London area sites have limited modern distributions or are extinct in the U.K. Some of these species are associated with the dead wood found in primeval forests; others are wetland species whose habitat has been severely reduced in recent centuries. The third group is stream-dwelling beetles that require clean, clear waters and river bottoms.

PumaPlex 1.0: Data generated during the development of the SNP markers and SNP genotypes of pumas

Pumas are one of the most studied terrestrial mammals because of their widespread distribution, substantial ecological impacts, and conflicts with humans. Extensive efforts, often employing genetic methods, are undertaken to manage this species. However, the comparison of population genetic data is difficult because few of the microsatellite loci chosen are shared across research programs. Here, we describe the development of PumaPlex, a high-throughput assay to genotype 25 single nucleotide polymorphisms in pumas. We validated PumaPlex in more than 700 North American pumas (Puma concolor couguar), and demonstrated its ability to generate reproducible genotypes and accurately identify individuals. Furthermore, we compared PumaPlex with traditional genotyping of 12 microsatellite loci in fecal DNA samples and found that PumaPlex produced significantly more genotypes with fewer false alleles. PumaPlex promotes the cross-laboratory comparison of genotypes, is easily expandable in the future, and is a valuable tool for the genetic monitoring and management of North American puma populations.

Pollen and spore deposition in different areas of the Lena Delta

Studies of the annual pollen and spore deposition in different areas of the Lena Delta were undertaken for the first time in the Asian sector of the Arctic during the Russian-German ''LENA 98'' and ''LENA 99'' expeditions in the framework of the International ''Laptev Sea System-2000'' Project. To achieve this objective, three spore-pollen traps were set up along the meridional delta profile in accordance with the European Pollen Monitoring Programme for the period July 1998 to August 1999. A comparison between the results of spore-pollen analysis of the contents of traps and the surrounding vegetation was performed. The results confirmed the current spore-pollen spectra are comprised both of pollen and spores of the local plants and of long-distance pollen and spores. The dependence of the long-distance pollen deposition on the character of the wind regime of the region was established. The prevailing southerly and southeasterly wind direction determines the main pollen influx of tree species from the areas of their growth south of the delta. The features of the morphological structure and fossilization of pollen and the features of the productive capability and plant growing conditions are of large significance in the pollen transfer and deposition.
