Learning is defined as behavioral modification due to experience, social or asocial. Social learning might be less costly than asocial learning and allow the rapid accumulation of learned traits across generations. However, the benefits of social learning in a small population of individuals relying on local interactions and experiencing environmen...

Ecological niche models (ENMs) are an essential modelling technique in biodiversity prediction and conservation and are frequently used to forecast species responses to global changes. Classic species‐level models may show limitations as they assume species homogeneity, neglecting intraspecific variation. Composite ENMs allow the integration of int...

This paper explores spatial and temporal patterns in the abundance of parrotfish assemblages along trhe northern coastof the Dominican Republic. We show high spatial and temporal variability for these assemblages at dofferent spatial scales. Parrotfish along localities and sites are dominated by small-size species and small-size individuals. These...

Plasticity is found in all domains of life and is particularly relevant when populations experience variable environmental conditions. Traditionally, evolutionary models of plasticity are non-mechanistic: they typically view reactions norms as the target of selection, without considering the underlying genetics explicitly. Consequently, there have...

This study introduces a comparative macro-geographic research focused on assessing whistles’ variation in three separate populations of common bottlenose dolphin, Tursiops truncatus. Two populations are distributed in an oceanic habitat and are geographically isolated, namely: Archipelago of Revillagigedo (RVG) in the Mexican Pacific and Archipelag...

In human infants babbling is an important developmental stage of vocal plasticity to acquire maternal language. To investigate parallels in the vocal development of human infants and non-human mammals, seven key features of human babbling were defined, which are up to date only shown in bats and marmosets. This study will explore whether these feat...

Bioacoustic analyses of animal vocalizations are predominantly accomplished through manual scanning, a highly subjective and time-consuming process. Thus, validated automated analyses are needed that are usable for a variety of animal species and easy to handle by non-programing specialists. This study tested and validated whether DeepSqueak, a use...

Populations adapt to novel environmental conditions by genetic changes or pheno-typic plasticity. Plastic responses are generally faster and can buffer fitness losses under variable conditions. Plasticity is typically modeled as random noise and linear reaction norms that assume simple one-to-one genotype-phenotype maps and no limits to the phenoty...

Mutations are the ultimate source of genetic variation. A question that has repeatedly arisen is, whether the mutation rate undergoes evolutionary change, depending on the environmental conditions, such that evolvability is enhanced. In asexual unicellular organism, elevated mutation rates arise under stressful conditions and are among the factors...

Background Edge effects can influence species composition and community structure as a result of changes in microenvironment and edaphic variables. We investigated effects of habitat edges on vegetation structure, abundance and body mass of one vulnerable Microcebus species in northwestern Madagascar. We trapped mouse lemurs along four 1000-m trans...

Background: Organisms are expected to respond to changing environmental conditions through local adaptation, range shift or local extinction. The process of local adaptation can occur by genetic changes or phenotypic plasticity, and becomes especially relevant when dispersal abilities or possibilities are somehow constrained. For genetic changes t...

A contemporary challenge in Ecology and Evolutionary Biology is to anticipate the fate of populations of organisms in the context of a changing world. Climate change and landscape changes due to anthropic activities have been of major concern in the contemporary history. Organisms facing these threats are expected to respond by local adaptation (i....

A challenge for eco-evolutionary research is to better understand the effect of climate and landscape changes on species and their distribution. Populations of species can respond to changes in their environment through local genetic adaptation or plasticity, dispersal, or local extinction. The individual-based modeling (IBM) approach has been repe...

In this project we developed an IBM and focused on local adaptation: genetic changes and phenotypic plasticity. We investigated (i) how the mutation rate is influenced by genomic properties and the rate of environmental change, (ii) how adaptive and non-adaptive plasticity affects persistence of populations with different life strategy under direct...

The flowchart diagram depicts the general procedure used to perform the similuations: behavioral strategies, enviromental scenarios and parameter values. Each simulation run consisted of two patches, white and black respectively, randomly placed in the environment, and of ten (10) mobile individuals or agents randomly positioned in the environment,...

Abstract. Characterization pf the whistles of Tursiops truncatus (Cetacea: Delphinidae) and their association with surface behavior. Acoustic communication is common in dolphins and encompasses a variety of sounds, either vocal or not. Among vocalizations, whistles are continuous narrow-band and frequency-modulated sounds, with a frequency range be...
