Activity pattern and habitat selection by invasive wild boars (Sus scrofa) in brazilian agroecosystems. Repositório Alice
MARTINS, F. I.; MOURAO, G. de M.; CAMPOS, Z. M. da S.; PELLEGRIN, A. O.; SILVA, V. S..
Wild boar populations are rapidly spreading through midwest Brazil, causing crop damage, impacting biodiversity and, possibly, spreading diseases to livestock. Despite their threat, little is known about introduced populations in Brazilian agricultural landscapes. The critical lack of knowledge about basic aspects of wild boar spatial ecology led us to evaluate home range sizes, activity pattern and habitat selection in interface regions of agricultural crops and natural riparian forests. We captured and monitored seven individuals using global position system collars throughout 19 to 77 days. The home range sizes calculated by Minimum Convex Polygon and Biased Random Bridge Kernel ranged from 273 to 1253 ha (median = 497 ha) and from 129 to 779 ha (median...

Activity patterns, home-range size, and habitat utilization of Sarpa salpa (Teleostei : Sparidae) in the Mediterranean Sea ArchiMer
Jadot, Catherine; Donnay, A; Acolas, M; Cornet, Y; Begout, Marie-laure.
Acoustic telemetry was used to record diel movement and habitat utilization of the salema (Sarpa salpa) (Teleostei: Sparidae) during three consecutive summers from 2000 to 2002 in the Calvi and Achiarina bays of Corsica in the Mediterranean Sea. A total of 18 fish was equipped with acoustic transmitters inserted in the body cavity, 13 were tracked in the Bay of Calvi (275 mm +/- 26.9 L-F), and 5 in Achiarina Bay (260 mm +/- 33.6 LF). Two different systems were used to track the fish. The one used in the Bay of Calvi was a manual receiver and a directional hydrophone. The second system, used in Achiarina Bay, was a radioacoustic-positioning (RAP) system that continuously monitored the movements of the fish. Fish positions were put in a geographic...

Áreas de acción en un ensamble de roedores del Desierto del Monte (Mendoza, Argentina) Mastozool. neotrop.
Corbalán,Valeria E.; Ojeda,Ricardo A..
In the central portion of the Monte desert four small rodent species coexist: Graomys griseoflavus, Akodon molinae, Eligmodontia typus, and Calomys musculinus . Using the Convex Polygon Method, we assessed the home range of these species at different habitats and made comparisons among species, and between sexes and different seasons of the year. We found that home range did not differ among species, but there is a tendency to increase range size as the species corporal size increases. Overlapping of home range was different at different seasons of the year, probably due to different population densities, but home range size was constant along the year. Habitat type and sex affect home range only for G. griseoflavus and A. molinae, respectively.

Contrasted habitats and individual plasticity drive the fine scale movements of juvenile green turtles in coastal ecosystems ArchiMer
Chambault, Philippine; Dalleau, Mayeul; Nicet, Jean-benoit; Mouquet, Pascal; Ballorain, Katia; Jean, Claire; Ciccione, Stéphane; Bourjea, Jerome.
Background A strong behavioural plasticity is commonly evidenced in the movements of marine megafauna species, and it might be related to an adaptation to local conditions of the habitat. One way to investigate such behavioural plasticity is to satellite track a large number of individuals from contrasting foraging grounds, but despite recent advances in satellite telemetry techniques, such studies are still very limited in sea turtles. Methods From 2010 to 2018, 49 juvenile green turtles were satellite tracked from five contrasting feeding grounds located in the South-West Indian Ocean in order to (1) assess the diel patterns in their movements, (2) investigate the inter-individual and inter-site variability, and (3) explore the drivers of their daily...

Habitat use and movements of Glossophaga soricina and Lonchophylla dekeyseri (Chiroptera: Phyllostomidae) in a Neotropical savannah Rev. Bras. Zool.
Aguiar,Ludmilla M.S.; Bernard,Enrico; Machado,Ricardo B..
The greatest current threat to terrestrial fauna is continuous and severe landscape modification that destroys and degrades animal habitats. This rapid and severe modification has threatened species, local biological communities, and the ecological services that they provide, such as seed dispersal, insect predation, and pollination. Bats are important pollinators of the Cerrado (woodland savanna) because of their role in the life cycles of many plant species. However, there is little information about how these bat species are being affected by habitat loss and fragmentation. We used radio-tracking to estimate the home ranges of Glossophaga soricina (Pallas, 1776) and Lonchophylla dekeyseri Taddei, Vizotto & Sazima, 1983. The home range of G....

Home range of a Geoffroy's marmoset group, Callithrix geoffroyi (Primates, Callitrichidae) in South-eastern Brazil BJB
PASSAMANI,M.; RYLANDS,A. B..
The home range of one group of the Geoffroy's marmoset (Callithrix geoffroyi) was studied in a fragment of the Atlantic Forest in south-eastern Brazil, between February 1993 and January 1994. The total home range was 23.3 ha and the area used in the dry season was significantly larger than that of the wet season. The smallest distance travelled by group was 480 m/day in May and the longest was 1,980 m/day in March, but with no significant differences between seasons. The total home range used for this species agrees with the ecological grouping of the genus Callithrix proposed by Rylands & Faria (1993) and may be associated with the habitat structure, the limit of the fragment and the inexistence of neighbouring groups.

Home range of the Tropidurid lizard Liolaemus lutzae: sexual and body size differences BJB
ROCHA,C. F. D..
The home range of the Tropidurid lizard Liolaemus lutzae, an endemic species of the costal sand dune habitats of Rio de Janeiro State, was studied in the beach habitat of Barra de Maricá restinga, Maricá County. Home ranges were studied using a mark-recapture technique in a delimited area at the beach habitat. I considered for estimates and analysis the home ranges of those lizards with a minimum of four positions. The size of L. lutzae home ranges varied according to the segment of the population. The mean home range size of adult males (x = 59.8 ± 33.7 m²) was significantly larger than that of adult females (x = 22.3 ± 16.1 m²). Juvenile mean home range size was significantly smaller than that of adult males, but did not differ from that of adult females...

Movements of Norway rats (Rattus norvegicus) in two poultry farms, Exaltación de la Cruz, Buenos Aires, Argentina Mastozool. neotrop.
Gómez Villafañe,Isabel E.; Muschetto,Emiliano; Busch,María.
The aim of this work was to study the range of movements of Norway rats in two poultry farms in Exaltación de la Cruz, Buenos Aires Province. Three female and three male rats were followed by radio-telemetry. The mean home range was 0.024 ha (0.0024 to 0.0525 ha) and the mean maximum distance between localization points was 33.70 m (10 m to 66 m). The maximum daily movement registered was 65 m. Individuals captured near sheds or pigpens did shorter displacements than those captured on the perimeter of each farm. Our results indicate that Norway rats moved only short distances in poultry farms.

Panthers and Forests in South Florida: an Ecological Perspective Ecology and Society
Comiskey, E. Jane; University of Tennessee; ecomiske@tiem.utk.edu; Bass, Jr., Oron L; Everglades National Park; Sonny_Bass@nps.gov; Gross, Louis J; University of Tennessee; gross@tiem.utk.edu; McBride, Roy T; Livestock Protection Company;; Salinas, Rene; University of Tennessee; salinas@tiem.utk.edu.
The endangered Florida panther (Puma concolor coryi) survives in an area of pronounced habitat diversity in southern Florida, occupying extensive home ranges that encompass a mosaic of habitats. Twenty-one years of daytime monitoring via radiotelemetry have provided substantial but incomplete information about panther ecology, mainly because this method fails to capture movement and habitat use between dusk and dawn, when panthers are most active. Broad characterizations of panther habitat suitability have nonetheless been derived from telemetry-based habitat selection studies, focusing narrowly on forests where daytime resting sites are often located. The resulting forest-centered view of panthers attributed their restricted distribution and absence of...

Radiotelemetry of a female jaú, Zungaro jahu (Ihering, 1898) (Siluriformes: Pimelodidae), passed upstream of Funil Dam, rio Grande, Brazil Neotropical Ichthyology
Alves,Carlos Bernardo Mascarenhas; Silva,Luiz Gustavo Martins da; Godinho,Alexandre Lima.
Jaú, Zungaro jahu (Ihering, 1898), a large migratory catfish endemic to the rio da Prata basin, has a fragile conservation status and its ecology is poorly known. We radio-tracked a female jaú with a total length of 1.5 m that was passed upstream of Funil Dam, rio Grande, to describe its migratory movements, habitat use, linear home range, and diel activity. To track the fish, we made five tracking trips in the period from April, 2003 to January, 2004. In addition to the main body of Funil Reservoir, the fish also used a reservoir-river transition zone located in a branch of Funil Reservoir that flooded part of rio das Mortes. Most of the times, we found the fish in the former beds of streams flooded by the reservoir, at depths that ranged from 8-9 m in...

Range structure, microhabitat use, and activity patterns of the saxicolous lizard Tropidurus torquatus (Tropiduridae) on a rock outcrop in Minas Gerais, Brazil RChHN
RIBEIRO,LEONARDO B; SOUSA,BERNADETE M; GOMIDES,SAMUEL C.
Although Tropidurus is a widely distributed lizard genus in South America and the Galapagos Islands, studies on space use and spatial distribution are scarce. We studied the home range structure of the saxicolous lizard Tropidurus torquatus based on the inland population of a rock outcrop in Minas Gerais State, southeastern Brazil. Lizards were individually marked and observed during reproductive and non-reproductive seasons. Using the mínimum convex polygon method, we found that average total range size of males during the reproductive season was larger than that of females, and that both had similar total range sizes in the non-reproductive season. The harmonic mean method showed that males have a larger home range size than that of females during both...

Tamanho da área de vida e padrão de uso do espaço em grupos de sagüis, Callithrix jacchus (Linnaeus) (Primates, Callitrichidae) Zoologia
Castro,Carla Soraia Soares de.
The influence of abundance and distribution of fruits and gums resources in home range size and pattern of range use were investigated in Callithrix jacchus. From October 1996 to January 1998 two groups (QT and PB) that lived in a National Forest/IBAMA-RN in northeastern Brazil (6º5'S, 35º12'W), were observed once a week by instantaneous scan sampling. The frequency of quadrant's visit in the home range was recorded at five minute intervals. Trees used for feeding on fruits and/or gum by the study groups were marked with flagging tape and numbered. Samples of the food items were collected for identification. Data on the temporal variation in fruits abundance was based on the monthly phenological observations of the marked trees. Study groups showed small...

Territorial-like defensive behavior of floral resources by Heliconius ethilla narcaea Godart over H. sara apseudes (Hübner) (Lepidoptera, Nymphalidae, Heliconiinae) Zoologia
Rocha,Carlos Frederico Duarte da; Duarte,Marcelo.
The use of nectar and pollen of a bromeliad by two heliconiine butterflies, Heliconius ethilla narcaea Godart, 1819 and H. sara apseudes (Hübner, [1813]) (Lepidoptera, Nymphalidae, Heliconiinae), is herein reported. Observations were made during a pollination study of Aechmea gracilis Lindman (Bromeliaceae, Bromelioidea) in a second-growth forest of the village Vila Dois Rios, Ilha Grande, Rio de Janeiro State, southeastern Brazil. Field observations showed that H. ethilla can be more aggressive than H. sara in exploiting A. gracilis floral resources. Temporal differences in the use of these resources were also observed: H. sara remained comparatively less time on flowers than H. ethilla.

Use of the space by the opossum Didelphis aurita Wied-Newied (Mammalia, Marsupialia) in a mixed forest fragment of southern Brazil Zoologia
Cáceres,Nilton Carlos.
Use of the space by the opossum Didelphis aurita Wied-Newied, 1826 (Mammalia, Marsupialia) in a mixed forest fragment of southern Brazil. The space use of the marsupial Didelphis aurita was studied in a forest fragment of southern Brazil from February 1995 to January 1996. The method used was the 'distribution utilization' in which each trap was set in 38 x 38 m quadrats. Captures of each marked individual in each point give information on its habitat use. Food availability was searched and compared to the habitat utilization and to the food consumption of opossums. Distribution patterns of captures (aggregated to random) and spatial overlap between individuals were searched. Results showed aggregated distributions of individuals, particularly females, in...
