Long-term studies in a 2,178ha fragment of semideciduous Atlantic Forest demonstrated important interactions between white-lipped peccaries (Tayassu pecari) and the common palms, Syagrus romanzoffiana and Euterpe edulis. We conducted fruit removal and medium-to-large-sized mammalian exclusion experiments to: (1) quantify seasonal fruit consumption...

In many mammals social organization promotes genetic structuring, which can be influenced by the dispersal pattern of the species. We analyzed the population genetic structure and dispersal of white-lipped peccaries (Tayassu pecari) from the Pantanal, Brazil. We genotyped 100 individuals at 7 microsatellite loci from 2 adjacent locations with no ob...

Many vertebrate species undergo population fluctuations that may be random or regularly cyclic in nature. Vertebrate population cycles in northern latitudes are driven by both endogenous and exogenous factors. Suggested causes of mysterious disappearances documented for populations of the Neotropical, herd-forming, white-lipped peccary ( Tayassu pe...

The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer-reviewed, and gray literature and in unpublished raw data. Camera traps are an effective non-invasive method of surveying vertebrates, applicable to different scales of time and...

Resource selection analysis (RSA) is a cornerstone approach for understanding animal distributions, yet there exists no rigorous quantification of sample sizes required to obtain reliable results. We provide closed-form mathematical expressions for both the number of animals and relocations per animal required for parameterising RSA to a given degr...

O porco-monteiro do Pantanal é uma espécie icônica. Introduzido nesta área pelos primeiros colonizadores da região, tornou-se asselvajado a partir do fim do século 19. Desde então, ampliou gradativamente suas distribuição e abundância, ocupando hoje praticamente todo o Pantanal. Ao longo desses mais de 120 anos de ocupação pantaneira, o porcomontei...

How species persist in fragmented habitats is essential to understanding species resilience in response to increasing anthropogenic pressures. It has been suggested that expansion in dietary niche allows populations to persist in human-modified landscapes, yet this hypothesis has been poorly tested in highly diverse ecosystems such as tropical fore...

Piebaldism, leucism or albinism are different types of pigmentation anomalies related to the excess or deficit of pigmentation in some regions or in the whole body of an animal. It is extremely rare in peccaries and has never been reported for Tayassu, a genus endemic to Neotropical region. Tayassu pecari, known as white-lipped peccaries (WLP's), h...

Mammals are important components of biodiversity that have been drastically and rapidly impacted by climate change, habitat loss, and anthropogenic pressure. Understanding key species distribution to optimize conservation targets is both urgent and necessary to reverse the current biodiversity crisis. Herein, we applied habitat suitability models f...

Because global climate change results in increasingly extreme temperatures and more frequent droughts, behavioral thermoregulation is one avenue by which species may adjust. Changes in activity patterns in response to temperature have been observed in a number of mammal species, but rarely have been investigated in humid tropical habitats. Here we...

1. Sample size sufficiency is a critical consideration for estimating Resource‐Selection Functions (RSFs) from GPS‐based animal telemetry. Cited thresholds for sufficiency include a number of captured animals M ≥ 30 and as many relocations per animal N as possible. These thresholds render many RSF‐based studies misleading if large sample sizes were...

This edition of the magazine presents one of the first assessments of fire impacts and the long-term consequences that will affect the Pantanal over the coming years. There is also an encouraging report of resilience, as in the case of hyacinth macaws, whose nests were impacted by fire during the peak of their reproductive season at Caiman Ecologic...

en Much of what remains of the Earth's tropical forests is embedded within agricultural landscapes, where forest is reduced and fragmented. As native forest ungulates are critical to maintaining forest function, it is imperative to understand how this functional group responds to declines in forest cover and connectivity resulting from agricultural...

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 and can generate a considerable direct or indirect income to the local communities. To meet many of the sustainable develop...

A reduction in the frequency of rainfall and an increase in drought periods, as a consequence of climatic change, has caused the desiccation of water ponds (locally known as “aguadas”) in the Calakmul region. The objective of this study was to determine if the abundance and distribution of the white-lipped peccary, Tayassu pecari, and the collared...

New proposals for tax incentives, wildlife management, fire control, participatory zoning and tourism itineraries are of interest to all Pantanal residents. Along with maintaining traditions that teach and educate, these actions ease isolation and act as resources for indigenous resistance. These are some of the topics covered in this fifth issue o...

White-lipped peccaries (WLPs; Tayassu pecari, Tayassuidae, Cetartiodactyla) are forest-dwelling ungulates critical to maintaining healthy Neotropical forest ecosystems through key aspects of their dietary behaviors, including seed predation and dispersal. Land-use change and deforestation threaten WLP access to food resources, and thus knowledge of...

In general, habitat fragmentation is associated with a reduction in gene flow that can reduce the genetic diversity, and, consequently, a species ability to survive environmental changes. The white-lipped peccary (Tayassu pecari) is a Neotropical ecosystem engineer that is vulnerable throughout its distribution area and under different degrees of t...

White-lipped peccaries (WLPs) are known as forest-dependent species and are thus expected to respond negatively to deforestation. Yet, little is known about how WLP herds use agricultural lands where high portions (i.e., more than 50%) of the native forest have been removed. In order to understand how WLPs access and use forested habitats nested wi...

Fluxos e dinâmicas biológicas comandam o cotidiano pantaneiro. A paisagem não é só um espaço estático no qual transitam pessoas, fauna e fl ora, mas um cenário ativo, determinante para o modo de vida de todas as comunidades. As cheias (ou a falta delas) governam a pesca, o turismo, a agricultura, a pecuária, a vida e a morte. Os diferentes hábitats...

Polygyny in mammals, as in other groups, is related to sexual dimorphism, with males being larger than females or with elaborate weaponry as a response to sexual selection. However, sexual selection can also act on females, leading to cases where dimorphism is reversed or absent and females mate with several males, leading to a promiscuous mating s...

Prior geochemical work documents dietary shifts coincident with climate change in extinct peccaries, with taxa typically shifting between browsing and mixed-feeding. This study employs dental microwear texture analysis (DMTA) and stable carbon isotopes to interpret the diet of extinct peccaries in Florida, specifically Platygonus, Mylohyus, and Pro...

Here we compile a data set comprising morphological and life history information of 279 mammal species from 39,850 individuals of 388 populations ranging from 5.83 to 29.75 decimal degrees of latitude and 34.82 to 56.73 decimal degrees of lon- gitude in the Atlantic forest of South America. We present trait information from 16,840 individ- uals of...

Measures of traits are the basis of functional biological diversity. Numerous works consider mean species-level measures of traits while ignoring individual variance within species. However, there is a large amount of variation within species and it is increasingly apparent that it is important to consider trait variation not only between species,...

We used 2 years of camera-trap surveys conducted by citizen scientists to compare native mammal and bird visits to dominant fruiting-tree species in low and high cattle-impact areas of rarely-flooded ?cordilheira? forests in the Brazilian Pantanal. Monthly fruit censuses showed greater diversity of fruiting-tree species in low cattle-impact areas....

Acoustic communication is particularly important in environments such as dense tropical forests, where the dim light constrains the efficacy of visual signals. In these environments, complex species interactions could promote the evolution of acoustic signals and result in intriguing patterns of mimicry and convergence. In the Neotropical region, N...

Liquid lunch – vampire bats feed on invasive feral pigs and other ungulates V ampire bats have long captivated the imagination of humans worldwide. Although often associated with myths about Dracula-like creatures (Mayen 2003), only three of about 1200 known bat species – Desmodus rotun-dus, Diaemus youngi, and Diphylla ecaudata, all restricted to...

Vampire bats have long captivated the imagination of humans worldwide. Although often associated with myths about Dracula-like creatures, only three of about 1200 known bat species – Desmodus rotundus, Diaemus youngi, and Diphylla ecaudata, all restricted to the New World – feed exclusively on blood. Of these, the common vampire bat (D. rotundus) h...

Nenhum outro bioma brasileiro conta com tantas experiências de longo prazo – tradições mesmo – e uma cultura tão voltada para a boa convivência entre homem e natureza como o Pantanal. Bois, cervos, jacarés e tuiuiús frequentam as mesmas vazantes sem atrapalhar um ao outro, para tranquilidade de quem vive no Pantanal e deleite dos turistas. Araras f...

Group living among ungulates has evolved mainly in species living in open habitats, such as grasslands and savannas, whereas in the forest, few ungulate species form groups and these tend to be small. Therefore, the white-lipped peccary (Tayassu pecari), a Neotropical ungulate listed as Vulnerable by the IUCN, represents an almost unique social occ...

Inter-specific competition is considered one of the main selective pressures affecting species distribution and coexistence. Different species vary in the way they forage in order to minimize encounters with their competitors and with their predators. However, it is still poorly known whether and how native species change their foraging behavior in...

In the neotropics, white-lipped peccaries (Tayassu pecari) are important indicators of intact natural landscapes and the status of medium to large-sized mammals dependent on forest habitats (Altrichter et al. 2012). Recognizing the species’ value as an environmental indicator of landscape and forest conditions in the southern Pantanal, we evaluated...
