Knowledge on biodiversity is fundamental for conservation strategies. The Brazilian Pampa region, located in subtropical southern Brazil, neglected terms of conservation, and knowledge its fragmented. We aim to answer the question: how many, which, species occur Pampa? In a collaborative effort, we built lists plants, animals, bacteria, fungi that Pampa. included information distribution patterns, main habitat types, status. Our study resulted referenced totaling 12,503 (12,854 taxa, when...
Effectiveness of pitfall traps for sampling amphibians and reptiles in Brazil.The etfectiveness 01' pittàll associated with drift fences to capture three field studies, Rio Grande do Sul (extreme southern Brazil), São Paulo (São Paulo, southeastern Amazonas (Amazonas, northern Brazil) is described.At Santa Maria, a total 2040 were caught 30 pitfalls (200 L, fence) during 18 months ofstudy (capture efficiencies 3.78 reptiles/pitfall /month 0.14 snake/pittà ll/month).At Itirapina, , 1262...
Este estudo teve como objetivo determinar a riqueza, constância de ocorrência, os modos reprodutivos, o padrão distribuição da abundância, temporada vocalização e testar correlação das variáveis climáticas sobre atividade dos anuros em uma região do Bioma Pampa, Santa Maria, Rio Grande Sul. Durante período novembro 2001 outubro 2002 foram realizadas coletas mensais empregando método ‘busca sítio reprodução’ exame exemplares depositados na Coleção Herpetológica Setor Zoologia Universidade...
Anurans are important prey for the American bullfrog Lithobates catesbeianus , but field assessments of its diet in context a local assemblage lacking. We aimed to identify frog species consumed by an invasive population subtropical South America, and assess their relative importance among other types prey. Characterization study area also allowed us calculate degree electivity recorded anuran prey, order gain insight regarding feeding preferences test if composition differed from random...
Abstract Epictia munoai is a small scolecophidian snake from the subtropical region of South America. It inhabits under rocks preserved environments. Since basic information concerning biology this remains unknown, we aimed at presenting on age, reproductive cycle, and daily annual activity patterns E. Southernmost Brazil. Males females becomes sexually mature 3 to 4 years presents life expectancy up 9 or 10 years. The breeding cycle individual level cyclical discontinuous, seasonal...
ABSTRACT Motivation Here, we make available a second version of the BioTIME database, which compiles records abundance estimates for species in sample events ecological assemblages through time. The updated expands 1.0 database by doubling number studies and includes substantial additional curation to taxonomic accuracy records, as well metadata. Moreover, now provide an R package (BioTIMEr) facilitate use database. Main Types Variables Included is composed one main data table containing 11...
The community structure of pond systems is affected by resource competition, predation and degree permanence water. Here we evaluated the effect permanence–predation gradient in ponds on species richness guild composition tadpoles. study was carried out at Caçapava do Sul southern Brazil. Tadpoles invertebrate predators were sampled 38 different sizes degrees permanence. collections twice, spring 2007 summer 2008. We ordinated a single dimension through non-metric multidimensional scaling....
Visual communication has evolved independently in several families of frogs and is complex diurnal stream frogs. In addition to isolated visual acoustic signals, some species may emit multimodal displays characterized by the association these signals. Through analysis focal recordings obtained situ southern Brazil, we investigated frog Crossodactylus schmidti . We found a repertoire nine signals used intraspecific communication, which signal Both legs kicking was described for first time....
ABSTRACT The increased incidence of solar ultraviolet B (UVB) radiation has been proposed as an environmental stressor, which may help to explain the enigmatic decline amphibian populations worldwide. Despite growing knowledge regarding UV-induced biological effects in several models, little is known about efficacy DNA repair pathways. In addition, attention given interplay between these molecular mechanisms with other physiological strategies that avoid damage induced by sunlight. Here,...
Context Species richness is a relevant diversity component of community ecology and many standardised techniques are available for data estimations. However, each technique appropriate to few environment types has its own sampling biases. Thus, it necessary test the effectiveness traditional heterodox in different habitat types, especially highly diverse taxonomic groups, such as anurans. Aims We present comparison based on species detection between following techniques: acoustic survey with...
Abstract The activity and space parameters (home range use of space) for a population Tupinambis merianae was recorded through 640 h observation during nine months, by monitoring 56 marked individuals. There significant difference in the periods stipulated this study throughout months. Active lizards were not registered before 7:30 a.m., nor after 6:00 p.m. greatest level individuals occurred November December. Fluctuations size different age classes studied We minimum home-range three males...
The composition of the anuran community Turvo State Park was compared with that other localities Mesophytic semideciduous Forest, aiming to test hypothesis situated nearest Misiones nucleus support new phytogeographic unit, known as Tropical Seasonal Forests Region. In total 32 amphibian species were recorded in park area and surroundings: Anura, 30 native one exotic; Gymnophiona, species. ordination among 20 Forest showed formation three groups 45% similarity: group 1, composed...
The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological sites throughout Brazil and its logic been applied in some other southern-hemisphere countries. supports aspects of necessary understand the processes that affect it. There are presently 161 sampling (see them at Supplementary Appendix), most which use a standardized methodology allows comparisons...
We record for the first time Crossodactylus schmidti (Anura: Hylodidae) and Proceratophrys avelinoi Cycloramphidae) from Rio Grande do Sul State, Brazil, based on individuals captured in an area of Mesophytic Semideciduous Forest, Parque Estadual Turvo, located northwest region state. These records extend geographical range both species about 60 km nearest known locality, Municipality San Vicente, Misiones, Argentina. provide a characterization calling site used by males schmidti, we also...
A fauna de serpentes do bioma Caatinga é uma das menos estudadas Brasil. Estudamos a assembleia área arbustivo-arbórea fim descrever história natural espécies ocorrentes na região. Um total 636 indivíduos 22 quatro famílias foi registrado. distribuição abundâncias log-normal e composição apresenta típicas sendo Oxybelis aeneus (Wagler, 1824) Philodryas nattereri Steindachner, 1870 as mais comuns. cada espécie descrita partir informações sobre padrões atividade, dieta, uso ambiente,...
Abstract Aims We identify alien reptiles and amphibians, invaders or not, in Brazil evaluate the following: (a) which species are found country; (b) where they originate from; (c) how distributed; (d) why were introduced; (e) factors affect record incidences local richness of these species. Location Brazil.

Abstract The emergence period and winter aggregations of a population Tupinambis merianae from southern Brazil as well some behavioural aspects its post‐emergence are examined. Fifty‐six individuals were captured marked in 64 days (640 h) field study. Most the hibernacula identified beneath human constructions. first emerged August last active ones observed April. population's shows protandric pattern, where males emerge before females, both adults juveniles. After emerging, basked up to 13...
The signaler-eavesdropper interaction has been investigated for a wide range of organisms, and although many flies feed on calling frogs, this dynamic addressed only poorly in the austral Neotropics. We southern Brazil using pairs suction traps (acoustic + silent) broadcasting frog calls or an artificial white noise ponds streams. From 139 sessions, genera Corethrella (Corethrellidae), Forcipomyia (Ceratopogonidae) Uranotaenia (Culicidae) were collected, including five species, most abundant...
O estudo foi desenvolvido no Campus da Universidade Federal de Santa Maria (UFSM), localizado na Depressão Central do Rio Grande Sul, bioma Pampa.
