Article
Full-text available
According to the acoustic adaptation hypothesis, communication signals are evolutionary shaped in a way that minimizes its degradation and maximizes its contrast against the background noise. To compare the importance for call divergence of acoustic adaptation and hybridization, an evolutionary force allegedly promoting phenotypic variation, we com...
Article
Full-text available
We examine factors that influence male mating success in the glass frog Centrolene savagei; in addition, we describe courtship behaviour, oviposition and early parental behaviour. Fieldwork was conducted in the Colombian Andes during the rainy season from April 2006 to January 2011. Larger males had more chances of mating than smaller males; neithe...
Article
Full-text available
Acoustically communicating species have evolved adaptations that allow them to transmit information and overcome signal masking where their habitat is disturbed by anthropogenic noise. To investigate whether calling behaviour or spatial distribution is related to road traffic noise we studied the poison frog Andinobates bombetes in a mid-elevation...
Article
Full-text available
The structure of assemblages may be determined by interspecific interactions or environmental factors (e.g. competition and habitat filtering). Since communication between conspecific and heterospecific affects fitness of individuals, habitat characteristics that prevent communication could determine habitat use and co-occurrence of species. Howeve...
Article
According to the acoustic adaptation hypothesis, abiotic noise generated by streams should promote the evolution of high-pitched signals in acoustically communicating animals. The putatively selective effect is best demonstrated by studying trait-environment correlations across recently or currently diverging lineages, and when we understand the ec...
Article
Full-text available
In anurans, vocalisations are the main behavioural modality of communication. Hence, the description of acoustic signals in anur-ans is important for understanding many aspects of their biology. We describe for the first time the advertisement calls for eight glass frog species (Centrolene antioquiensis, "Centrolene" robledoi, Nymphargus caucanus,...
Article
The term ‘mate guarding’ refers to the monopolization of the reproductive potential of a conspecific. Mate guarding has been recorded in invertebrates and vertebrates, but is poorly known in anuran amphibians (frogs and toads), the terrestrial vertebrates with the highest diversity of reproductive modes. Mate guarding in anurans may consist of a pr...
Article
Full-text available
Parental care directly affects the fitness of individuals because it increases the probability of offspring survival. Therefore, it is expected that parents be particularly motivated to return (i.e., exhibit homing behavior) and resume care if they are moved away from offspring by disturbances. Yet, despite several studies on the behavioral ecology...
Article
Accelerated rates of urbanization negatively impact natural habitats and biodiversity. Studies of the effects of urbanization on fauna have emphasized taxonomic diversity, but this does not necessarily reflect effects on the evolutionary history of assemblages. Here, we study how urbanization influences phylogenetic diversity (PD) of bird assemblag...
Article
Full-text available
Many organisms have evolved adaptations to increase the odds of survival of their offspring. Parental care has evolved several times in animals including ectotherms. In amphibians, ~ 10% of species exhibit parental care. Among these, poison frogs (Dendrobatidae) are well-known for their extensive care, which includes egg guarding, larval transport,...
Article
Full-text available
Vocalizations are one of the most important communication modalities in amphibian biology, and advertisement call is the type of vocalization mostly emitted by anurans (frogs and toads). In the present study, we carried out a scientometric analysis of the advertisement call in species of anurans in Colombia to determine the state of knowledge of th...

Full-text available
Las señales acústicas son una de las formas de comunicación más importante en la fauna, incluso en la ubicación espacial de los individuos y sus presas. El estudio de las señales acústicas fortalece los campos de investigación en ecología, comportamiento, identificación taxonómica, uso de hábitat e incluso el efecto de las actividades humanas sobre...
Article
Full-text available
Describing natural history of species is important because it would allow us to corroborate hypotheses about evolutionary biology and improve conservations plans. We describe the advertisement call, tadpole morphology, and other natural history aspects of the poison frog Andinobates daleswansoni, an endemic threatened species of the Colombian Andes...
Article
Anthropogenic noise, characterized by higher intensities at low frequencies, can restrict acoustic communication between conspecifics and eventually reduce the fitness of populations. We analysed changes in the call features of 52 males of the poison frog A. bombetes subjected to anthropogenic noise through playback experiments. Thirty-one males di...
Article
The abiotic noise of streams can mask the acoustic signals of anurans with a large body size calling at low frequencies, but not the signals emitted by anurans with a small body size calling at high frequencies. As a consequence, the body size of species in assemblages alongside streams is, on average, lower and less variable than that of assemblag...
Article
Full-text available
The interaction between homing and parental care offers insights about the motivational aspects underlying movement patterns in animals. For species that care for offspring at fixed locations, offspring mortality in the absence of care might impact a parent’s motivation to home after being displaced from young. We tested whether homing motivation i...
Article
Homing is a behavior in which an animal returns to a specific place after they have moved or migrated to a distant place. In anurans, most of our knowledge about homing comes from studies in temperate-region species with nocturnal activity and reproduction associated with ponds. Recently, studies with poison frogs (Dendrobatidae) have increased our...
Article
Full-text available
Studies of phenology and natural history of anurans provide information useful for its conservation. This is particularly important in current scenarios of emergent diseases, high rates of deforestation, and climate change. We recorded the timing of breeding of the Glass Frog Nymphargus grandisonae and its relationship to precipitation and environm...
Article
Full-text available
The acoustic signals in Atelopus (Anura: Bufonidae), a Neotropical genus currently composed of 97 species, are poorly known. In this study, we describe for the first time, the advertisement, release, and agonistic calls of Atelopus laetissimus, an endangered species endemic to the Sierra Nevada de Santa Marta, in northern Colombia. The calling beha...
Article
Full-text available
The persistence of fauna carcasses on roads has been considered one of the most relevant factors influencing estimates of road mortality in different taxonomic groups. However, there is a lack of information in this regard in most Neotropical countries. The aim of the present research is to describe and quantify the persistence of snake carcasses o...

Full-text available
We describe for the first time the tadpole of two endemic harlequin frogs of the Sierra Nevada de Santa Marta, north of Colombia: Atelopus nahumae and A. laetissimus. In addition, we provide further morphological data for a third species, A. carrikeri. We also discuss some external morphological features for the tadpoles of these species and compar...
Article
Full-text available
Anurans are good study models for a better understanding of the behavioral ecology of parental care in vertebrates because such behavior evolved multiple times independently in frogs and toads; moreover, forms of parental care are highly diverse in those vertebrates and according to the species is performed by the male, the female, or both sexes. I...
Article
The evolution and diversification of animal reproductive modes have been pivotal questions in behavioural ecology. Amphibians present the highest diversity of reproductive modes among vertebrates, involving various behavioural, physiological and morphological traits. One such feature is the amplexus, which is the clasp or embrace of males on female...
