Tongue spots of dunnock nestlings vary in number and position over time but exert no clear influence on parental allocation
Published: 2020-05-15
Subjects: Other Social and Behavioral Sciences, Social and Behavioral Sciences
The nestlings of many bird species have ornaments in their mouths (e.g., tongue spots), yet the within-species variation of these ornaments remains poorly explored. Here, we described a subtle and intriguing pattern of variation in the tongue spots of dunnock (Prunella modularis) nestlings and further evaluated their potential influence on parental feeding allocation. We observed that tongue [...]
Small-scale farming in drylands: New models for resilient practices of millet and sorghum cultivation
Published: 2020-05-11
Subjects: Agriculture, Life Sciences, Other Social and Behavioral Sciences, Social and Behavioral Sciences
Finger millet, pearl millet and sorghum are amongst the most important drought-tolerant crops worldwide. They constitute primary staple crops in drylands, where their production is known to date back over 5000 years ago. Compared to other crops, millets and sorghum have received less attention until very recently, and their production has been progressively reduced in the last 50 years. Here, we [...]
COVID-19 has led to a global increase in web searches for bats: a risk for conservation ?
Published: 2020-04-29
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Life Sciences, Other Social and Behavioral Sciences, Research Methods in Life Sciences, Social and Behavioral Sciences
SARS-CoV-2, the virus that caused COVID-19 pandemic, is genomically similar to a SARS-like beta-coronavirus found in Chinese rhinolophids. This evolutionary relationship impressed global media, which emphasized bats as key actors in the spillover during the pandemic outbreak. In this study we highlight qualitative and quantitative changes about bats in the media coverage, and Internet search [...]
The Evolutionary Ecology of Age at Natural Menopause: Implications for Public Health
Published: 2020-02-11
Subjects: Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Life Sciences, Medicine and Health Sciences, Other Ecology and Evolutionary Biology, Other Medicine and Health Sciences, Other Social and Behavioral Sciences, Physiology, Social and Behavioral Sciences
Evolutionary perspectives on menopause have focused on explaining why early reproductive cessation in females has emerged and why it is rare throughout the animal kingdom, but less attention has been given to exploring patterns of diversity in age at natural menopause. In this paper, we aim to generate new hypotheses for understanding human patterns of diversity in this trait, defined as age at [...]
The trade-off between information and pathogen transmission in animal societies
Published: 2020-02-04
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Social and Behavioral Sciences, Social and Behavioral Sciences
Social structure can regulate information and pathogen transmission via social contact or proximity, which ultimately affects individual fitness. In theory, the same network properties that favor social information transmission also favor the spread of socially-transmitted pathogens, creating a trade-off between them. The mechanisms underlying the development and stability of individual [...]
Comparing ecological and evolutionary variability within datasets

Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Genetics and Genomics, Life Sciences, Other Ecology and Evolutionary Biology, Other Genetics and Genomics, Social and Behavioral Sciences
Many key questions in evolutionary ecology require the use of variance ratios such as heritability, repeatability, and individual resource specialization. These ratios allow to understand how phenotypic variation is structured into genetic and non-genetic components, to identify how much organisms vary in the resources they use or how functional traits structure species communities. Understanding [...]
Time is money. Waiting costs explain why selection favors steeper time discounting in deprived environments.
Published: 2019-12-04
Subjects: Other Psychology, Other Social and Behavioral Sciences, Psychology, Social and Behavioral Sciences
Individuals exposed to deprivation tend to show a characteristic behavioural syndrome suggestive of a short time horizon. This pattern has traditionally been attributed to the intrinsically higher unpredictability of deprived environments, which renders waiting for long term rewards more risky (i.e. collection risks are high). In the current paper, based on a simple dynamic life history model, we [...]
Mapping the dynamics of research networks in ecology and evolution using co-citation analysis (1975–2015)
Published: 2019-08-02
Subjects: Ecology and Evolutionary Biology, Life Sciences, Social and Behavioral Sciences
In this paper we used a co-citation network analysis to quantify and illustrate the dynamic patterns of research in ecology and evolution over 40 years (1975–2014). We addressed questions about the historical patterns of development of these two fields. Have ecology and evolution always formed a coherent body of literature? What ideas have motivated research activity in subfields, and how long [...]
The Evolutionary Psychology of Scientific Publishing: Cost-Benefit Optimization of Players in the Game
Published: 2019-07-11
Subjects: Psychology, Social and Behavioral Sciences
Peer reviewed scientific publishing is critical for communicating important findings, interpretations and theories in any branch of science. While the value of peer review is rarely doubted, much concern is being raised about the possible biases in the process. I argue here that most of the biases originate in the evolved innate tendency of every player to optimize one’s own cost benefits. [...]
Toward a Pluralistic Conception of Resilience

The concept of resilience occupies an increasingly prominent position within contemporary efforts to confront many of modernitys most pressing challenges, including global environmental change, famine, infrastructure, poverty, and terrorism, to name but a few. Received views of resilience span a broad conceptual and theoretical terrain, with a diverse range of application domains and settings. In [...]
Communicative roots of complex sociality and cognition
Published: 2019-06-21
Subjects: Animal Sciences, Biology, Integrative Biology, Life Sciences, Social and Behavioral Sciences
Mammals living in more complex social groups typically have large brains for their body size and many researchers have proposed that the primary driver of the increase in brain size through primate and hominin evolution are the selection pressures associated with sociality. Many mammals, and especially primates, use flexible signals that show a high degree of voluntary control and these signals [...]
Heritability and maternal effects on social attention during an attention bias task in a non-human primate, Macaca mulatta
Published: 2019-05-02
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Medicine and Health Sciences, Other Medicine and Health Sciences, Psychology, Social and Behavioral Sciences
Social attention is fundamental to a wide range of behaviours in non-human primates. However, we know very little about the heritability of social attention in non-human primates, and the heritability of attention to social threat has not been assessed. Here, we provide data to begin to fill this gap in knowledge. We tested 67 female rhesus macaques, Macaca mulatta, on an attention bias [...]
A continental measure of urbanness predicts avian response to local urbanization

Understanding species-specific relationships with their environment is essential for ecology, biogeography, and conservation biology. Moreover, understanding how these relationships change with spatial scale is critical to mitigating potential threats to biodiversity. But methods which measure inter-specific variation in responses to environmental parameters, generalizable across multiple spatial [...]
