E-mail: Abstract: 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. ThePuma Private concolor Reserve of NaturalLeopardus Heritage pardalis(PRNH) Amadeu BotelhoPuma is isolatedyagouaroundi 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 ( ), ocelot ( ) and jaguarundi ( ) 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.

Using this method, we important in the entire region (Conselho Nacional da walked along the roads that pass through the forest (Figure 2) Reserva da Biosfera da Mata Atlântica 2008). Albeit well preserved, the ERAB is located far away from other forest fragments and is virtually the only refuge for forest species within a radius of 30 kilometers. The forest fragment is a watershed, whose two extremes, (northwest-southeast direction), reach the Santo Antônio and João da Velha streams (Figure 1). These streams are tributaries of Jaú River (Figure 1), whose closest point to ERAB is 50 meters (Conselho Nacional da Reserva da Biosfera da Mata DataAtlântica collection 2008).

We used this method to attempt to identify the animals that leave the forest and possibly use Sandthe plantations plots to feed on or shelter in. To record the tracks of animals that rarely leave the forest, we used the sand plot technique. Each plot consists of a square of PVC pipe that delimits 0.80 × 0.80 m (that delimits an area of 0.64 m²). This square is placed on the Figure 3. forest floor and about 3 to 4 cm of clear sand is placed inside it (Figure 4). Stretch of road transect between cornfields of Santo Antonio dos Ipês Farm (Photo: Ricardo Reale). Three trails about 150 m long were made from the border of the forest into its interior. Two groups of sand plots were placed on each trail (Figure 5), each group comprising four plots spaced 10–15 m apart, forming a square on the forest floor, according to the unpublished method recommended by Nature Conservation Laboratory of UNESP’s Department of Forest Sciences at Botucatu. The border effect can cause changes in fauna, particularly in species with low tolerance for open areas (Laurance 1999). To minimize this problem, the first group of plots was placed at a distance of 100 meters from the border and the second group at 150 m from the border and 50 m from the first group. The trails were made as straight as possible. Figure 4.

FRAGASZY Department of Psychology, University of Georgia, Athens, Georgia Prior studies have claimed that nonhuman primates plan their routes multiple steps in advance. However, a recent reexamination of multi‐step route planning in nonhuman primates indicated that there is no evidence for planning more than one step ahead. We tested multi‐step route planning in capuchin monkeys using a pointing device to “travel” to distal targets while stationary. This device enabled us to determine whether capuchins distinguish the spatial relationship between goals and themselves and spatial relationships between goals and the laser dot, allocentrically. In Experiment 1, two subjects were presented with identical food items in Near‐Far (one item nearer to subject) and Equidistant (both items equidistant from subject) conditions with a laser dot visible between the items. Subjects moved the laser dot to the items using a joystick. In the Near‐Far condition, one subject demonstrated a bias for items closest to self but the other subject chose efficiently. In the second experiment, subjects retrieved three food items in similar Near‐Far and Equidistant arrangements. Both subjects preferred food items nearest the laser dot and showed no evidence of multi‐step route planning. We conclude that these capuchins do not make choices on the basis of multi‐step look ahead strategies. Am. J. Primatol. 76:828–841, 2014. © 2014 Wiley Periodicals, Inc.

  • Limitations of Selective Deltamethrin Application for Triatomine Control In
    Grijalva et al. Parasites & Vectors 2011, 4:20 http://www.parasitesandvectors.com/content/4/1/20 RESEARCH Open Access Limitations of selective deltamethrin application for triatomine control in central coastal Ecuador Mario J Grijalva1,2*, Anita G Villacís2, Sofía Ocaña-Mayorga2, César A Yumiseva2, Esteban G Baus2 Abstract Background: This year-long study evaluated the effectiveness of a strategy involving selective deltamethrin spraying and community education for control of Chagas disease vectors in domestic units located in rural communities of coastal Ecuador. Results: Surveys for triatomines revealed peridomestic infestation with Rhodnius ecuadoriensis and Panstrongylus howardi, with infestation indices remaining high during the study (13%, 17%, and 10%, at initial, 6-month, and 12-month visits, respectively), which indicates a limitation of this strategy for triatomine population control. Infestation was found 6 and 12 months after spraying with deltamethrin. In addition, a large number of previously vector-free domestic units also were found infested at the 6- and 12-month surveys, which indicates new infestations by sylvatic triatomines. The predominance of young nymphs and adults suggests new infestation events, likely from sylvatic foci. In addition, infection with Trypanosoma cruzi was found in 65%, 21% and 29% at initial, 6-month and 12-month visits, respectively. All parasites isolated (n = 20) were identified as TcI. Conclusion: New vector control strategies need to be devised and evaluated for reduction of T. cruzi transmission in this region.

We covered a lot of ground and visited a great series of parks, lodges, and reserves, racking up a respectable group list of 459 bird species seen as well as some nice mammals. There was a lot of rain in the area, but we had to consider ourselves fortunate that the rainiest days seemed to coincide with our long travel days, so it really didn’t cost us too much in the way of birds. My personal trip favorite sighting was our amazing and prolonged encounter with a rare Helmeted Woodpecker! Others of note included extreme close-ups of Spot-winged Wood-Quail, a surprise Sungrebe, multiple White-necked Hawks, Long-trained Nightjar, 31 species of antbirds, scope views of Variegated Antpitta, a point-blank Spotted Bamboowren, tons of colorful hummers and tanagers, TWO Maned Wolves at the same time, and Giant Anteater. This report is a bit light on text and a bit heavy of photos, mainly due to my insane schedule lately where I have hardly had any time at home, but all photos are from the tour. www.tropicalbirding.com +1-409-515-9110 [email protected] Tropical Birding Trip Report Southeast Brazil: Atlantic Rainforest and Savanna, Oct-Nov 2016 The trip started in the city of Curitiba.

    BETWEEN SPECIES: CHOREOGRAPHING HUMAN AND NONHUMAN BODIES JONATHAN OSBORN A DISSERTATION SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY GRADUATE PROGRAM IN DANCE STUDIES YORK UNIVERSITY TORONTO, ONTARIO MAY, 2019 ã Jonathan Osborn, 2019 Abstract BETWEEN SPECIES: CHOREOGRAPHING HUMAN AND NONHUMAN BODIES is a dissertation project informed by practice-led and practice-based modes of engagement, which approaches the space of the zoo as a multispecies, choreographic, affective assemblage. Drawing from critical scholarship in dance literature, zoo studies, human-animal studies, posthuman philosophy, and experiential/somatic field studies, this work utilizes choreographic engagement, with the topography and inhabitants of the Toronto Zoo and the Berlin Zoologischer Garten, to investigate the potential for kinaesthetic exchanges between human and nonhuman subjects. In tracing these exchanges, BETWEEN SPECIES documents the creation of the zoomorphic choreographic works ARK and ARCHE and creatively mediates on: more-than-human choreography; the curatorial paradigms, embodied practices, and forms of zoological gardens; the staging of human and nonhuman bodies and bodies of knowledge; the resonances and dissonances between ethological research and dance ethnography; and, the anthropocentric constitution of the field of dance studies. ii Dedication Dedicated to the glowing memory of my nana, Patricia Maltby, who, through her relentless love and fervent belief in my potential, elegantly willed me into another phase of life, while she passed, with dignity and calm, into another realm of existence. iii Acknowledgements I would like to thank my phenomenal supervisor Dr. Barbara Sellers-Young and my amazing committee members Dr.

Parasites Vectors (2021) 14:195 https://doi.org/10.1186/s13071‑021‑04647‑z Parasites & Vectors RESEARCH Open Access Under pressure: phenotypic divergence and convergence associated with microhabitat adaptations in Triatominae Fernando Abad‑Franch1,2* , Fernando A. Monteiro3,4*, Márcio G. Pavan5, James S. Patterson2, M. Dolores Bargues6, M. Ángeles Zuriaga6, Marcelo Aguilar7,8, Charles B. Beard4, Santiago Mas‑Coma6 and Michael A. Miles2 Abstract Background: Triatomine bugs, the vectors of Chagas disease, associate with vertebrate hosts in highly diverse ecotopes. It has been proposed that occupation of new microhabitats may trigger selection for distinct phenotypic variants in these blood‑sucking bugs. Although understanding phenotypic variation is key to the study of adaptive evolution and central to phenotype‑based taxonomy, the drivers of phenotypic change and diversity in triatomines remain poorly understood. Methods/results: We combined a detailed phenotypic appraisal (including morphology and morphometrics) with mitochondrial cytb and nuclear ITS2 DNA sequence analyses to study Rhodnius ecuadoriensis populations from across the species’ range. We found three major, naked‑eye phenotypic variants. Southern‑Andean bugs primarily from vertebrate‑nest microhabitats (Ecuador/Peru) are typical, light‑colored, small bugs with short heads/wings. Northern‑ Andean bugs from wet‑forest palms (Ecuador) are dark, large bugs with long heads/wings. Finally, northern‑lowland bugs primarily from dry‑forest palms (Ecuador) are light‑colored and medium‑sized. Wing and (size‑free) head shapes are similar across Ecuadorian populations, regardless of habitat or phenotype, but distinct in Peruvian bugs. Bayesian phylogenetic and multispecies‑coalescent DNA sequence analyses strongly suggest that Ecuadorian and Peruvian populations are two independently evolving lineages, with little within‑lineage phylogeographic structuring or diferentiation.
