“…Some studies indicate that this is a species with very limited ecological flexibility, and is only common in well-preserved areas of mature forests (Pardini et al 2005;Pardini and Umetsu 2006). While Grazzini et al (2015) found high densities of T. nigrita in Araucaria (Araucaria angustifolia) and Pinus sp. plantations in a Mixed Ombrophilous Forest, the species occurred at low densities compared to other Akodontini in studies of lowland Atlantic Forest (Gatto-Almeida et al 2016).…”

Open pit rubbish dumps generate serious environmental problems both in Brazil and elsewhere. The goal of this study was to evaluate the occurrence patterns of an assemblage of small flightless mammals in the area of a landfill deactivated 19 years ago. During nine campaigns, three different sites located in a subtropical protected area near the city of Matinhos, Paraná coast, southern Brazil, were sampled. The selected places were an artificial clearing where urban waste had previously been dumped (Area 1), a site with less anthropic influence with tree species and a poorly developed understorey (Area 2), and a site with well-formed vegetation, with herbaceous, shrubby and tree strata well developed (Area 3). The total capture effort was 5210 trap-nights; 109 captures were made of 82 individuals from five species of Rodentia (all from the subfamily Sigmodontinae) and three species of marsupials (Order Didelphimorphia). The most conserved site (Area 3) had higher abundance than areas 1 and 2 (binomial test; P<0.05). Area 1, considered the most affected, showed less species richness (n=6) than the other two areas (7 and 8 species), although this may be affected by the lower number of captures. The diversity in Area 1, estimated by the Shannon index, was lower than in areas 2 and 3 (Hutcheson’s t tests; H’=1.26 for Area 1 vs. 1.76 and 1.68 for Areas 2 and 3, respectively), although the composition of the assemblage did not differ significantly between the areas (PERMANOVA; P=0.085). Our results show that even after 19 years of inactivity, the deposited waste is still having a negative impact on the environment, and highlight the resilience of some native small mammal species in exploiting the resources of degraded areas.

“…A useful way to understand the potentially negative effects of landscape modification on native animals is to consider the range of processes that can threaten a particular individual species (Fischer and Lindenmayer, 2007). For example, the orders Rodentia and Didelphimorphia are groups of small mammals, composed of small rodents and marsupials, highly specialized in the maintenance of neotropical ecosystems, with a relevant role in seed dispersal and consequently in the recovery and reforestation process of impacted areas (Grazzini et al, 2015). Many species of these two orders are threatened by habitat loss and fragmentation, which have led to a pronounced decline in their richness and abundance (Grazzini et al, 2015).…”

Natural ecosystems are in constant conflict with the growing and disordered urban expansion, arising from the mismanagement of human developments and infrastructure, facing an accelerated rate of deforestation and defaunation. The intense pressure on natural environments impacts the local fauna through various incidents, generating high mortality, such as hit-and-run, window-crashing, attacks by domestic animals, dissemination of diseases and electrocution. The purpose of this study was to carry out a retrospective survey of the wild fauna rescued and treated at a clinic associated with the environmental police in the region of Joinville - SC. A total of 379 wild animals were treated at the clinic from 2014 to 2016. Of these, 262 (69.13%) were birds, 107 (28.23%) mammals, 9 (2.37%) reptiles and 1 (0.26%) amphibian. The main causes of referral for clinical care were due to trauma (50.66%), seizures (1.32%) and other causes (48.02%), such as home invasion and orphaned puppies. Among the reasons for traumas, pedestrian accidents were the most prevalent, representing 39.58% of the cases treated, followed by animals found to be debilitated without a defined cause (31.77%), attack by domestic animals (14.58%) and window-crashing (9.89%). The data obtained in this study show a rich diversity of species in Joinville. These species are exposed to several anthropogenic challenges and barriers derived mainly from intense displacement and human invasion, causing many animals to move in order to adapt to urban areas.

“…Additionally, different species in a community respond differently to trapping methods (De Bondi et al 2010, Gaston 2000, Karp et al 2012, Umetsu et al 2006 and the same method can lead to confounding results regarding community and population studies (Barros et al 2015). Several authors agree that further investigations on the performance of different sampling methods are still necessary (Ardente et al 2017, Balieiro et al 2015, Barros et al 2015, Grazzini et al 2015. Although previous studies have analysed which sampling methods maximize observed small mammal richness in the Atlantic forest biome (Bovendorp et al 2017, Moura et al 2008, they did not analyse to what extent this sampling bias can mask important ecological patterns in forest fragments, such as the effects of the surrounding matrix and the effect of the still unclear species-area relationship (Fahrig 2017, Fahrig et al 2019, Fletcher et al 2018.…”

Small mammals in fragments of Atlantic Forest: species richness answering to field methods and environment

Small mammals can be used as environmental indicators and have been intensively studied in fragmented landscapes of Atlantic Forest, with a wide range of field methods. Our aim in this study was two-fold: we tested for the effects of methods and for the effects of the main environmental variables on observed small mammal richness in fragments of Atlantic Forest. We gathered information on small mammal richness, methods and environmental variables from 122 fragments of Atlantic Forest through literature review. These data were analysed using linear models and model selection based on AIC values along with a regression tree analysis. We found that studies will record more species with bigger trapping effort, using pitfall traps and sampling all forest strata. We also confirmed two important ecological assumptions: fragments at lower latitudes and bigger fragments were the ones with higher species richness. Methodological and environmental variables were analysed together on a regression tree, where trapping effort was the most important variable, surpassing any environmental effect. Considering that a significant number of the studies on Atlantic Forest fragments did not use pitfall traps or sample all forest strata, their results on forest fragmentation were affected by sampling bias.
