Bats are key components of ecological networks, and studies in degraded areas are especially important to understand the impact of the human settlements on bats communities. Here, we surveyed the bat fauna in Guaribas Biological Reserve, a protected area in the Atlantic Forest in Paraiba state, northeastern Brazil, and compared it with the bat fauna that occupies the nearby villages. In the villages, we recorded 650 individuals from 14 species, while 1,127 individuals from 20 species were recorded in the Reserve. Diversity estimation pointed out 19 species for the settlements, and 22 for the Reserve. A Bray-Curtis/Sorensen similarity cluster analysis informed that the Reserve areas and the villages form two distinct groups. Additionally, a Wilcox test pointed out that both areas have significantly distinct abundances and species richnesses. Only a subset of the assemblage, mainly formed by generalist or opportunist species, occupies the villages, exploring resources that are offered by human activities.

The Private Reserve of Natural Heritage Fazenda Lontra/Saudade (FLS), located in the Northern Coast of Bahia state, Brazil, is the largest (1,377.33 ha) preserved Atlantic Forest area between Paraguaçu and São Francisco rivers in Bahia and Sergipe, respectively. A list of 260 species belonging to six families of butterflies is presented herein, being recorded 4 species of Papilionidae, 16 of Pieridae, 29 of Lycaenidae, 41 of Riodinidae, 87 of Nymphalidae and 83 of Hesperiidae. The butterfly community was composed mainly by widespread species commonly found in open habitats. There were also many species typical of forested areas, as such Morpho telemachus richardusFruhstorfer, 1898 (Nymphalidae: Morphini), a new record to the Northeastern Brazil.

Governments and environmental conservationists agree that wetland resources need to be utilized sustainably to ensure the continued presence of wetlands and their ecological goods and services. Ideally, wetlands should be integrated into the national and local land use plans to ensure sustainable use and management of the resources. However, this is not the case as far as Kenya is concerned. Instead, there is rampant exploitation of wetlands by individuals, organizations and even government agencies with no regard to environmental conservation. Therefore, this study was undertaken to investigate the impact of human activities on wetland conservation with a focus on the Sondu River Basin. The objective of the study was to establish the effects of human settlements on the conservation of the Sondu River Basin. The study was grounded on the integrated water resource management theory. This study adopted a concurrent triangulation research design which entailed a combination of both qualitative and quantitative data. The target population for the study was 164 respondents in which a sample of 144 respondents was selected using Slovin’s formula. The sample was randomly selected with the inclusion criterion being that the chosen respondents were homogeneously engaged in human activities that affected wetland conservation. Intensive data cleaning exercise was carried out including checking for outliers, missing data imputation and variable transformation. The collected data were analysed by use of descriptive statistics such as frequencies, percentages and summation and presented in the form of tables and charts. The results of the study will inform policy and practice in the management and conservation of the Sondu River wetland area. The study established that human activities such as farming, logging, construction, drilling, building and construction and settlements have immensely hampered conservation of Sondu wetland. Further, it was noted that it is indeed possible to gain vital information about the human activities responsible for the degradation of wetlands.

Abstract Toxoplasmosis is a parasitic disease, which is prevalent across the world and has a strong environmental component in its transmission chain. The present study determined the seroprevalence and factors related to Toxoplasma gondii infection among free-range chickens from an Atlantic Forest area in Northeastern Brazil. A total of 550 free-range chickens were tested for T. gondii antibodies usingthe indirect fluorescent antibody test (IFAT, cut-off point 1:16), and 269 (48.9%; 95% CI = 44.7-53.1%) were positive. Among the 61 properties 57 (93.4%) had at least one seropositive animal. The robust Poisson regression model showed that the variables/categories associated with the seroprevalence of T. gondii were: region of origin of the animals/urban area (prevalence ratio [PR] = 2.346; P<0.001), management system/use of cages (PR = 1.591; P = 0.019), presence of rodents/yes (PR = 1.295; P = 0.035), and the type of food/use of food scraps (PR = 1.603; P = 0.009). The high prevalence found suggest that this scenario demands careful management, mainly regarding the use of scraps of undercooked or raw food, adequate environmental hygiene and frequent rodentcontrol.

We evaluate the impact of very small and isolated forest fragments on the common marmosets home range, diet, and activity patterns, in the northeastern Atlantic Forest of Brazil. Three groups were studied in three forest fragments, from January to October 2010, totaling 360 hours of observations and 1,080 field-hours. Systematic observations were recorded using Instantaneous Scan Sampling, and a checklist of the items exploited was built throughad libitumobservations. We recorded location of the groups and calculated home range. We recorded 11,639 scans and 236ad libitumfeeding records. 83.4% (n=10) of food items were plant species, the only animal protein was from insects (n=2; 16.6%), and the diet was based almost exclusively on gums. Mean home range was 5.5 ha, mean daily path length was 1,167 meters, and no differences were detected between seasons. Resting dominated their activity budget and varied between seasons. Common marmosets survived in this environment through a remarkable increase in their exploitation of tree gums (up to 98% of their feeding bouts) to compensate for the lack of food, in home ranges slightly larger than in the literature. Thus, they travelled and foraged less than expected and rested more since food was easily obtained.

The Arvoredo Marine Biological Reserve (RBMA) is a protected area in southern Brazil created in 1990 to safeguard the marine biodiversity of the Arvoredo Archipelago. There are only few studies about bird assemblage in most of the Brazilian coastal islands, including this protected area. Therefore, this paper presents the first complete list of birds for RBMA based on data from literature and surveys between 1986 and 2012 on islands and surrounding waters. Birds were recorded during captures using mist-nets and opportunistic observations on land in January 2012, as well as in monthly strip-transects and sectors on sea between 2010 and 2012. The present list includes 84 species (15 captured) from primary data and 22 species from other sources, totaling 106 species from 37 families. Bird assemblage in the RBMA is composed by 44 aquatic birds and 62 landbirds, whereas 13 are endemic to the Atlantic Forest and 12 are threatened. As expected due to the diversity of habitats, Arvoredo and Galé Islands supported the richest assemblages in the RBMA. The number of species in the whole RBMA is smaller than bigger islands elsewhere in the Atlantic Forest domain, but similar to same-sized and same-habitat ones. Our results highlight the importance of this reserve as a suitable and isolated habitat to forest species. Deserta Island is an important site for nesting, resting, and foraging seabirds.
