“…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

et al. 2020

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.

“…Nesse sentido, trabalhos como este de inventário, se fazem necessários uma vez que, fornecem o embasamento necessário para atualizar o status de conservação de espécies, refinar seus mapas de distribuição, além de ajudar a desenvolver planos de manejo e propostas de conservação nas áreas estudadas (Guedes et al, 2000;Ceballos & Ehrlich, 2002;IUCN, 2014;Grazzini et al, 2015c).…”
