Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database 803 individuals 57 species, we found that mammals in areas with comparatively high human were average one-half to one-third extent their low footprint. We attribute this reduction behavioral changes individual animals exclusion long-range from higher impact. Global loss...
Building bridges between environmental and political agendas is essential nowadays in face of the increasing human pressure on natural environments, including wetlands. Wetlands provide critical ecosystem services for humanity can generate a considerable direct or indirect income to local communities. To meet many sustainable development goals, we need move our trajectory from current destructive wiser wetland use. The article contain proposed agenda Pantanal aiming improvement public policy...
Abstract: The Pantanal, one of the largest wetlands on planet, comprises 140,000 km 2 lowland floodplain upper Rio Paraguai basin that drains Cerrado central Brazil. diverse mosaics habitats resulting from varied soil types and inundation regimes are responsible for an extraordinarily rich terrestrial aquatic biota, exemplified by bird richest wetland in world—463 birds have been recorded there—and known populations several threatened mammals, such as Pampas deer ( Ozotoceros bezoarticus ),...
O método de levantamento aéreo foi adaptado e utilizado pela primeira vez para a elaboração mapas distribuição quantificação classes vegetação no Pantanal Mato-Grossense por sub-região. Foram identificadas 16 classes, baseando-se em aspectos fitofisionômicos, sendo as principais campo (31,1%), cerradão (22,1%), cerrado (14,3%), brejos (7,4%), mata semidecídua (4,0%), galeria 2,4% baceiro ou batume. Estas informações podem subsidiar escolha áreas conservação preservação, bem como auxiliar o...
Little is known on the role played by Neotropical wild carnivores in Trypanosoma cruzi transmission cycles. We investigated T. infection from three sites Brazil through parasitological and serological tests. The seven carnivore species examined were infected cruzi, but high parasitemias detectable hemoculture found only two Procyonidae species. Genotyping Mini-exon gene, PCR-RFLP (1f8/Akw21I) kDNA genomic targets revealed that raccoon (Procyon cancrivorus) harbored TcI coatis (Nasua nasua)...
Abstract Accurately quantifying species’ area requirements is a prerequisite for effective area‐based conservation. This typically involves collecting tracking data on species of interest and then conducting home‐range analyses. Problematically, autocorrelation in can result space needs being severely underestimated. Based the previous work, we hypothesized magnitude underestimation varies with body mass, relationship that could have serious conservation implications. To evaluate this...
Wild animals are infected by diverse parasites, but how they influence host health is poorly understood. We examined the relationship of trypanosomatids and gastrointestinal parasites with wild brown-nosed coatis (Nasua nasua) from Brazilian Pantanal. used coati body condition hematological parameters as response variables in linear models that were compared using an information theoretic approach. Predictors high/low parasitemias Trypanosoma cruzi T. evansi, indices representing abundance...
Abstract As water along dirt roads in the Pantanal floodplains diminishes, aquatic fauna becomes restricted to shallow pools. At end of 2009 dry season, we filmed giant otters living pools predating on yacare caimans. Such predation has not been recorded inhabiting Pantanal. Individual captured sub-adult The did share prey, but conspecifics stole it after conflicts. Caiman could be related resource scarcity these marginal environments. Information diet and interactions endangered populations...
Giant otters (Pteronura brasiliensis) live in groups that seem to abandon their territories during the flooding season. We studied spatial ecology of giant otter dry and wet seasons Vermelho Miranda rivers Brazilian Pantanal. monitored visually or by radiotelemetry 10 monthly from June 2009 2011. estimated home-range size for all with following methods: linear river length, considering extreme locations each group, fixed kernel. For radiotracked groups, we also used k-LoCoh method. Spatial...
The occurrence of Trypanosoma spp. in wild carnivore populations has been intensively investigated during the last decades. However, impact these parasites on health free-living infected animals largely neglected. Pantanal biome is world's largest seasonal wetland, harboring a great diversity species and habitats. This includes 174 mammals, which 20 belong to order Carnivora. present study aimed investigate effect evansi cruzi infections coinfections most abundant carnivores Pantanal: coati...
We investigated the home range size, habitat selection, as well spatial and activity overlap, of four mid-sized carnivore species in Central Pantanal, Mato Grosso do Sul, Brazil. From December 2005 to September 2008, seven crab-eating foxes Cerdocyon thous, brown-nosed coatis Nasua nasua, six ocelots Leopardus pardalis were radio-collared monitored. Camera trap data on these also collected for raccoon Procyon cancrivorus. hypothesized that there would be large niche differentiation preferred...
We have focused on the role played by a carnivore, coati (Nasua nasua), in transmission cycle of Trypanosoma cruzi Brazilian Pantanal biome. collected data during 2000/01 and 2005-07. Prevalence pattern T. infection were determined serological tests hemoculture. Isolates characterized miniexon molecular assay. Our results demonstrate that among coatis southern seems to be well established, as we found high serum prevalences parasitemias throughout two studied periods. Single infections TCII...
We examined by parasitological tests (hemocultures and buffy coat) infection Trypanosoma cruzi T. evansi in blood samples from Leopardus pardalis, Cerdocyon thous domestic dogs. Besides, 25 isolates previously derived feral pigs small wild mammals were here characterized miniexon gene demonstrated to be the TcI genotype. Herein, we make an overall analysis of transmission cycle both trypanosome species light assemblage data collected over last seven years. The carnivore Nasua nasua was...
ABSTRACT This study reports the effect of daily mean ambient temperature on activity and habitat use by giant anteater ( Myrmecophaga tridactyla ) in Pantanal wetlands Brazil. We equipped 11 anteaters with a global position system collar programmed to acquire location every 10 min for 15 d. A data logger left meteorological station at site registered temperature. Giant were mainly active open fields except during coldest days, when they sought protection inside forests. also used habitats...
Abstract To obtain data on home range, movements, activity and habitat use by giant anteaters Myrmecophaga tridactyla , seven animals were captured, radio‐collared monitored from March to December 2001 in a 104‐km 2 study area the Pantanal wetland, Brazil. Four of five males used areas that covered 4.0–7.5 km (5.7±1.7 ), one two females occupied larger (11.9 ) than males, but none curves cumulative unequivocally reached asymptote. Generally, there was considerable overlap among individual...
Abstract The purpose of this study was to correlate the activity and habitat use a large ecologically specialized mammal ( Myrmecophaga tridactyla ) with time day minimum daily temperature in Brazil's Pantanal wetland. Seven giant anteaters were fitted very high frequency (VHF) radio transmitters monitored from March December 2001. animal's state or rest, ambient recorded different patches site, which covered by mosaic vegetation types several ponds. Whenever anteater inside forest patch,...
AbstractThe giant otter (Pteronura brasiliensis) is a social species that defends territories along water bodies. Although some researchers have visually monitored otters during long periods at night, no nocturnal activity of the has been recorded and are currently believed to be strictly diurnal. In this study, we present information about patterns groups in Brazilian Pantanal, using radio telemetry camera trap data. We captured, implanted transmitters in, three male from different Miranda...
We studied the reproductive biology of a population Blue-fronted Amazons (Amazona aestiva) in Pantanal Mato Grosso do Sul State, Brazil, between 1997 and 1999. Nesting occurred from August to December. monitored 94 nests which were found trees different sizes. distributed all major vegetation associations (floodplains, grasslands, scrub savanna, arboreal riparian forests, pastures). about half (53%) an open disturbed area 34 km2, yielding density 0.5 nests/km2. In remaining 486 km2 study...
