Stable laws in a changing world The structure of evolutionary theories over the centuries

Liz Pásztor, Géza Meszéna

Published: 2022-09-27
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology

Successful fundamental theories are built on verifiable principles that include measurable variables. This paper shows that Darwin’s inclusive theory is built on such principles and follows their rocky road into modern operational theories. Besides reproduction, variation, and heredity, Darwin’s conditions of diversification also include the potential for exponential (geometric) population growth [...]

Using integrated multispecies occupancy models to map co-occurrence between bottlenose dolphins and fisheries in the Gulf of Lion, French Mediterranean Sea

Valentin Lauret, Hélène Labach, Léa David, et al.

Published: 2022-09-27
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology

In the Mediterranean Sea, interactions between marine species and human activities are prevalent. The coastal distribution of bottlenose dolphins (Tursiops truncatus) and the predation pressure they put on fishing stocks lead to regular interactions with fisheries. Multispecies occupancy models are a relevant framework to estimate co-occurrence between two (or more) species while accounting for [...]

Evaluation of DNA Extracted from Timber Rattlesnake (Cotalus horridus) Cloacal and Blood Swabs for Microsatellite Genotyping

Genetic research is a key component to modern wildlife conservation, but it is contingent on the collection of reliable and high-quality genetic samples. Invasive genetic sampling techniques have potential to negatively impact individuals, which may be prohibitive when working with threatened and endangered species. Prior to sample collection, project managers must try to balance the negative [...]

Open access research infrastructures are critical for sustained citizen science growth: a case study of Australia’s national biodiversity platform, the Atlas of Living Australia (ALA)

Erin Roger, Cameron Slayter, Dax Joseph Kellie, et al.

Published: 2022-09-23
Subjects: Ecology and Evolutionary Biology, Life Sciences

Citizen science continues to make a substantial contribution to a wide variety of scientific disciplines by allowing the public to be involved in activities like idea generation, study design, data collection and analysis. Although the pace of citizen science has exploded in recent decades, there remains untapped potential for scientific output through investment in research infrastructure that [...]

Individual identity information persists in learned calls of introduced parrot populations

Grace Smith-Vidaurre, Valeria Perez-Marrufo, Elizabeth A. Hobson, et al.

Published: 2022-09-23
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences

Animals can actively encode different types of identity information in learned communication signals, such as group membership or individual identity. The social environments in which animals interact may favor different types of information, but whether identity information conveyed in learned signals is resilient or responsive to social disruption over short evolutionary timescales is not well [...]

Linking Predator Responses to Alkaloid Variability in Poison Frogs

Justin P Lawrence, Bibiana Rojas, Annelise Blanchette, et al.

Published: 2022-09-21
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Zoology

Many chemically-defended/aposematic species rely on diet for sequestering the toxins with which they defend themselves. This dietary acquisition can lead to variable chemical defenses across space, as the community composition of chemical sources is likely to vary across the range of (an aposematic) species. We characterized the alkaloid content of two populations of the Dyeing Poison Frog [...]

New Global Species Biodiversity: Soil soars, Ocean flounders

Robert Blakemore

Published: 2022-09-16
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Population Biology

Based on topographic field data, an argument is advanced that Soil houses ~2.1 x 10^24 taxa and supports >99.9% of global species biodiversity, mostly Bacteria or other microbes. Contradictory claims that Soil is home to only a quarter of biota while Ocean harbours 80-99% of Life on Earth are both dismissed. Earlier guesstimates of ~8.8 million taxa (~2.2 million or 25% marine), of 1-6 [...]

Socio-ecological factors shape the distribution of a cultural keystone species in Malaysian Borneo

David J Kurz, Thomas Connor, Jedediah F. Brodie, et al.

Published: 2022-09-14
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology

Biophysical and socio-cultural factors have jointly shaped the distribution of global biodiversity, yet relatively few studies have quantitatively assessed the influence of social and ecological landscapes on wildlife distributions. We sought to determine whether social and ecological covariates shape the distribution of a cultural keystone species, the bearded pig (Sus barbatus). Drawing on a [...]

When and how does photoinhibition matter for plant fitness?

Published: 2022-09-13
Subjects: Botany, Ecology and Evolutionary Biology, Life Sciences, Physiology, Plant Biology, Plant Sciences, Population Biology, Terrestrial and Aquatic Ecology

The many biophysical factors that shape how plant species sort across environmental gradients may include photoinhibition, which I define broadly as oxidative damage that plants and other phototrophs risk incurring when they absorb excess light energy they cannot safely dissipate. Photoinhibition is seldom explicitly discussed as a potential driver of plant fitness and distributions. Here, I aim [...]

Effects of distinct data processing in the phylogenetic signature of foliar spectra of regenerating plants in Neotropical Forest gaps

Ecio Souza Diniz, Cibele Hummel do Amaral, Lucas Arthur de Almeida Telles, et al.

Published: 2022-09-13
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology

Important biochemical traits may be robustly mapped by optical spectroscopy, allowing inferences about phylogenetic conservation in plant species. However, distinct types of data processing might lead to distinct patterns of phylogenetic signal in the foliar spectra. Thus, investigate the standard analytical approaches in order to understand their influence over the phylogenetic signal is [...]

Foraging Efficiency and the Importance of Knowledge in Pemba, Tanzania: Implications for Childhood Evolution.

Ilaria Pretelli, Monique Borgerhoff Mulder, Bakar Makame Khamis, et al.

Subjects: Anthropology, Behavior and Ethology, Biological and Physical Anthropology, Ecology and Evolutionary Biology, Life Sciences, Social and Behavioral Sciences

Childhood is a period of life unique to humans. Childhood may have evolved through the need to acquire knowledge and subsistence skills. In an attempt to evaluate the importance of learning for the evolution of childhood, previous research examined the increase with age of returns to foraging across various resources. Any increase could be due to increases in knowledge or other factors such as [...]

The evolution of eusociality: Kin selection theory, division of labour models, and evo-devo explanations

Jan J Kreider, Ido Pen

Published: 2022-09-12
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences

The evolution of eusociality has long been recognized as an evolutionary paradox. We identify three different but complementary approaches to the study of the evolution of eusociality. Kin selection models explain why individuals can evolve to have distinct reproductive or non-reproductive roles. Division of labour models elucidate how specialisation can emerge and evolve. Conceptual models from [...]

Novel viral pathogens are causing diseases to emerge in humans, a challenge to which society has responded with technological innovations such as antiviral therapies. Antivirals can be rapidly deployed to mitigate severe disease, and with vaccines, save human lives and provide a long-term safety net against new viral diseases. Yet with these advances come unforeseen consequences when antivirals [...]

How much biodiversity is concealed in the word “biodiversity”?

Stefano Mammola, Caroline S. Fukushima, Girolama Biondo, et al.

Published: 2022-09-12
Subjects: Ecology and Evolutionary Biology, Life Sciences

Amidst a global biodiversity crisis, the word “biodiversity” has become indispensable for conservation and management. Yet, biodiversity is often used as a buzzword in scientific literature. Resonant titles of papers claiming to have studied “global biodiversity” may be used to promote research focused on a few taxonomic groups, regions, habitats, or facets of biodiversity [taxonomic, [...]

Publication bias impacts on effect size, statistical power, and magnitude (Type M) and sign (Type S) errors in ecology and evolutionary biology

Yefeng Yang, Alfredo Sánchez-Tójar, Rose E O'Dea, et al.

Subjects: Biology, Ecology and Evolutionary Biology, Environmental Sciences, Life Sciences, Physical Sciences and Mathematics, Statistics and Probability

Collaborative assessments of direct replicability of empirical studies in the medical and social sciences have exposed alarmingly low rates of replicability, a phenomenon dubbed the ‘replication crisis’. Poor replicability has spurred cultural changes targeted at improving reliability in these disciplines. Given the absence of equivalent replication projects in ecology and evolutionary biology, [...]
