Since its discovery in Lake Mead in 2007, the invasive quagga mussel (Dreissena rostriformis bugensis) has rapidly spread throughout the lower Colorado River drainage. However, the invasion in California remained confined to the Colorado and water systems throughout southern California that receive water from the Colorado River until December 2013, when quagga mussels were first observed in Lake [...]

Random DNA barcodes are a versatile tool for tracking cell lineages, with applications ranging from development to cancer to evolution. Here we review and critically evaluate barcode designs as well as methods of barcode sequencing and initial processing of barcode data. We first demonstrate how various barcode design decisions affect data quality and propose a new optimal design that balances [...]

Individual-based eco-evolutionary framework: towards unifying ecology and evolution

Jan Hrcek

Published: 2022-09-28
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences

Evolution is increasingly found to be rapid and entangled with ecological processes in complex eco-evolutionary dynamics, calling for a common conceptual framework. Yet, ecological and evolutionary theory remain largely separated, which constrains the development of integrative research. To overcome this separation, I argue for treating the entangled dynamics as a single eco-evolutionary process [...]

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 allow mapping co-occurrence between two (or more) species while accounting for false negatives and [...]

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.

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 parrot calls after invasion

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 communication signals, such as group membership, individual identity, or social status. 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 short-term changes in the social environment 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

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?

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 [...]

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 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 [...]
