“…In fact, seed dispersal by humans that live in traditional communities close to forested areas seems to be important for several plant species in the tropical region (guix 2009). to incorporate the role of paleoindians as seed dispersers, we assigned interactions to humans while assuming that the fruits used were the same as those used currently by the indigenous people that inhabit the Pantanal region (Pott et al 2011). this assumption is supported by the fact that there is evidence of the use of fruits of several species by indigenous people over the long term (scoles and gribel 2011).…”

Reconstructing past ecological networks: the reconfiguration of seed-dispersal interactions after megafaunal extinction

extinction and the arrival of humans changed how seed dispersers were distributed among network modules. however, the recent introduction of livestock into the seeddispersal system partially restored the original network organization by strengthening the modular configuration. moreover, after megafaunal extinctions, introduced species and some smaller native mammals became key components for the structure of the seed-dispersal network. We hypothesize that such changes in network structure affected both animal and plant assemblages, potentially contributing to the shaping of modern ecological communities. the ongoing extinction of key large vertebrates will lead to a variety of context-dependent rearranged ecological networks, most certainly affecting ecological and evolutionary processes.

“…As semelhanças nas condições edáficas e aspectos geomorfológicos entre a PIAP e o Pantanal podem ser também apontados como prováveis fatores para a existência de um considerável número de espécies (63 spp.) comuns a estas duas planícies inundáveis (Pott et al 1986, Allem & Valls 1987, Pott et al 1989, Pott et al 1992, Pott 1994, Prado et al 1994, Silva et al 1997, Heckman 1998, Pott et al 1999, Pott 2000, Pott & Pott 2000, Rebellato & Nunes-da-Cunha 2005, Pott & Pott 2009, Nunesda-Cunha & Junk 2011, Pott et al 2011, Filgueiras et al 2015.…”

-(Poaceae in a Brazilian floodplain: floristic checklist and new occurrences). This study aims to characterize the grass flora of the Upper Paraná River Floodplain (PIAP) and its environs, located at 22º38'-22º57'S and 53º05'-53º36'W, between the States of Paraná and Mato Grosso do Sul. We analyzed 916 botanical collections obtained from herbaria and fieldwork from 1988 to 2015. The occurrence of 50 genera and 94 species was confirmed, of which 68.08% are native and 31.92% are naturalized. Panicoideae is the most representative subfamily, encompassing 68.08% of the species, followed by Chloridoideae (12.24%) and Bambusoideae (11.22%), whereas Oryzoideae, Arundinoideae and Pooideae represent less than 10% of the species. Most species are perennial (80.85%), herbaceous (77.66%) or arbustive (12.77%), terrestrial (42.55%), or from boggy areas (37.24%). Seven species represent new records for the State of Mato Grosso do Sul, and seven for the State of Paraná.

Foram analisadas 916 exsicatas provenientes de coleções de herbário ou obtidas em campo entre 1988 e 2015. Como resultado, registra-se a ocorrência de 50 gêneros e 94 espécies, sendo 68,08% nativas e 31,92% naturalizadas. Panicoideae é a maior subfamília, com 68,08% das espécies, seguida de Chloridoideae (12,24%) e Bambusoideae (11,22%), ao passo que Oryzoideae, Arundinoideae e Pooideae representam menos de 10% das espécies. A maioria das espécies é perene (80,85%), porte herbáceo (77,66%) ou arbustivo (12,77%), terrestre (42,55%) ou palustre (37,24%). Sete espécies representam novos registros para o Mato Grosso do Sul e sete para o Paraná.

“…The management system employed in the PA must have been the main factor that led to the drastic reduction of suitable habitats and to the disappearance of feral pigs in this area. Important changes have been Pott et al 2011). Since then, deforestation and 'controlled' fires have been the main forms of clearing land used by Pantanal ranchers to increase cattle stocking rates (Harris et al 2005;Junk et al 2006;Seidl et al 2001;Wilcox 1992).…”

This paper focus a rare case of natural disappearance of feral pigs (Sus scrofa) in an extensive area without using traditional methods of eradication programs. The study was conducted both in the Private Reserve of Natural Heritage (PRNH) Sesc Pantanal and in an adjacent traditional private cattle ranch. In 1998 feral pigs were abundant and widely distributed in the PRNH. However, the feral pigs were gradually disappeared from the area and currently the absence of pigs in the PRNH contrasts with the adjacent cattle ranch where the species is abundant. To understand the current distribution of feral pigs in the region we partitioned the effects of variation of feral pigs presence considering the habitat structure (local), landscape composition and the occurrence of potential predators.Additionally, we modeled the distributions of feral pigs in Northern Pantanal, projecting into the past using the classes of vegetation cover before the PRNH implementation (year 1988). Our results show areas with more suitability for feral pigs in region are a landscape dominated by pastures and permeated by patches of Seasonal Dry Forest. The species tends to avoid predominantly forested areas. Additionally, we recorded that the environmental suitability for feral pigs decreases exponentially as the distance from water bodies increases. The disappearance of feral pigs into PRNH area seems to be associated with changes in the landscape and vegetation structure after the removal of the cattle.

The disappearance of feral pigs into PRNH area seems to be associated with changes in the landscape and vegetation structure after the removal of the cattle. In the Brazilian Pantanal the feral pigs occurrence seems strongly conditioned to environmental changes associated to livestock activity.PeerJ Preprints | https://doi.org/10.7287/peerj.preprints.2876v1 | CC BY 4.0 Open Access | rec: 15
