Building bridges between environmental and political agendas is essential nowadays in face of the increasing human pressure on natural environments, including wetlands. Wetlands provide critical ecosystem services for humanity can generate a considerable direct or indirect income to local communities. To meet many sustainable development goals, we need move our trajectory from current destructive wiser wetland use. The article contain proposed agenda Pantanal aiming improvement public policy...
The potential habitat range of the Green-Tailed Trainbearer, Lesbia nuna gouldii (Trochilidae), in northern Andes from Ecuador to Venezuela was modelled, using maximum entropy niche modelling, environmental covariates and records locations across Colombian Andes. predicted suitable corresponded well known subspecies L. n. Colombia clearly excluded Sierra Nevada. Therefore, these analyses suggest that this species should be removed Venezuelan bird list.
Climate change poses a critical threat to the Pantanal, largest wetland in world. Models indicate an increase frequency of extreme precipitation events and extended periods drought. These changes can amplify consequences for Pantanal's ecological functioning, which has already experienced intensive human modification its hydrological system environmental health. The present study analyzed spatial temporal dynamics rainfall resulting extremes Brazilian area Upper Paraguay River Basin (UPRB)...
Abstract Songs of wild male Anna hummingbirds ( Calypte anna ) consist syllables grouped into phrases. Nearest neighbors tend to share similar syllable types, rhythms and syntax. from different localities contain syntax repetition indices. A raised by hand in isolation produced a song consisting highly variable types wide frequency range. The was simple structure, were not Three males as group sang songs containing two stereotyped sung alternating sequence without phrase structure. These...
The first record of the Orthoptera species Lerneca inalata for Brazil is presented here. taxon represented by a new subspecies beripocone subsp. nov. (Phalangopsidae, Luzarinae), collected in Pantanal Poconé, Mato Grosso, Brazil. This work includes morphological and morphometric data as well descriptions female genitalia calling song. has diagnostic features male with six ventral spines on B sclerite, spine having subtle bifurcation; mid-region strongly sclerotized pseudepiphallus;...
Machine learning tools are widely used in support of bioacoustics studies, and there numerous publications on the applicability convolutional neural networks (CNNs) to automated presence-absence detection species. However, relation between merit acoustic background modelling recognition performance needs be better understood. In this study, we investigated influence substance detector White-lored Spinetail (Synallaxis albilora). Two designs were evaluated: 152-layer ResNet with transfer a...
<title>Abstract</title> Under the current global biodiversity crisis, there is a need for automated and non-invasive monitoring techniques that are able to gather large amounts of information cost-effectively at scales. One such technique passive acoustic monitoring, which commonly coupled with automatic identification animal species based on their sound. Automated sound analyses usually require training detection algorithms. These algorithms annotated datasets mark occurrence sounds...
This study investigated the influences of regional climate and soil moisture conditions on vegetative reproductive cycles seven savanna forest vegetation communities Pantanal Mato-grossense. Circular analysis phenological data revealed occurrence interspecific synchronism seasonal responses in activities, with flowering patterns differing most between communities. Leaf shedding intensity events were closely linked to climatic seasonality. Over half individuals semideciduous or deciduous,...
Computer-assisted species recognition facilitates the analysis of relevant biological information in continuous audio recordings. In present study, we assess suitability this approach for determining distinct life-cycle phases Southern Lapwing Vanellus chilensis lampronotus based on adult vocal activity. For purpose use passive 14-min and 30-min soundscape recordings (n = 33 201) collected 24/7 mode between November 2012 October 2013 Brazil's Pantanal wetlands. Time-stamped detections V....
Abstract Passive acoustic monitoring, when coupled with automated signal recognition software, allows researchers to perform simultaneous monitoring at large spatial and temporal scales. This technique has been widely used monitor cetaceans, bats, birds, anurans but rarely applied primates. Here, we evaluated the effectiveness of passive software for detecting presence roaring behavior Black Gold Howler Monkey ( Alouatta caraya ) over a complete annual cycle one site in Brazilian Pantanal....
The ecology of tropical wildlife remains unknown for most nocturnal species owing to difficulties in performing night surveys. To improve our understanding the birds, we monitored calling activity two Neotropical nightjars, Little nightjar (Setopagis parvula) and Common pauraque (Nyctidromus albicollis), over an annual cycle at four sites Brazilian Pantanal. both was restricted period showed peaks just before dawn after dusk. detected from early June late January migratory habits species,...
Current knowledge regarding the vocal behavior in tropical non-passerines is very limited. Here, we employed passive acoustic monitoring to study activity of white-tipped dove (Leptotila verreauxi) at three sites over a year Brazilian Pantanal. The diel pattern showed bimodal pattern, with significantly higher after sunrise than during other hours day, agreement prior studies on this species and members Columbidae. was vocally active throughout year, but maximum May-June lowest...
The moon phase affects the ecology and vocal activity of nightjars (Caprimulgidae). However, some studies have found contradictory results regarding impact on nightjars. To increase our knowledge this topic, we monitored behavior two Neotropical nigthjars, Little nightjar (Setopagis parvula) Common pauraque (Nyctidromus albicollis), over 5 lunar cycles in Brazilian Pantanal. We tested relationships between daily output (number calls uttered) proportions calling at dusk, midnight, dawn. Our...
Abstract Tinamous (Tinamidae) are a group of Neotropical birds for which little information is available. The Undulated Tinamou ( Crypturellus undulatus ) one the most widespread species but also declining. Due to its secretive habits, ecological knowledge regarding relies on few anecdotal descriptions. We used automated recorders monitor vocal activity over an annual cycle at four sites in Brazilian Pantanal. provide description and analyze diel seasonal patterns calling this new...
Chaco Chachalaca ( Ortalis canicollis) is a declining Neotropical bird, for which our current knowledge about its natural history very limited. Here, we evaluated first time the utility of passive acoustic monitoring, coupled with automated signal recognition software, to monitor Chachalaca, described vocal behavior species across diel and seasonal cycle patterns, proposed an monitoring protocol minimize error in estimation activity rate. We recorded over complete annual at three sites...
Bird vocal activity is affected by endogenous and exogenous factors. Owl surveys are mainly based on the detection of nocturnal calls, therefore, impact factors owls' may have consequences in conservation planning behavioural studies. However, our current knowledge about climatic moon phase owl calling behaviour very limited, especially Neotropics. We used autonomous recording units to evaluate effect air temperature, rainfall, relative humidity, percent illuminated occurrence...
