Hybridization has long been recognized as a fundamental evolutionary process in plants, but our understanding of its phylogenetic distribution and biological significance across deep evolutionary scales has been largely obscure—until recently. Over the past decade, genomic and phylogenomic datasets have revealed, perhaps not surprisingly, that hybridization, often associated with polyploidy, has [...]

Lineage-specific traits determine how plants interact with their surrounding environment. As different species may find similar phenotypic solutions through evolution to tolerate, persist in and invade environments with certain characteristics, some traits may become more common in certain types of habitats. These general patterns of geographical trait distribution point towards the existence of [...]

Human influence is driving planetary change, often in undesirable and unsustainable ways. Recent advances enabled us to measure changes in humanity’s footprint on Earth annually from 2000 – 2019 with a nine-fold improvement in spatial resolution over previous efforts. We found that earlier studies seriously under-estimated the magnitude, extent, and rate of change in the human footprint. [...]

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 [...]

The present work exploits internet resources to update previously reported data for the distributional range and ecology of Cistanthe philhershkovitziana Hershk. (Cistanthe Spach sect. Cistanthe; Montiaceae), a conspicuous and not uncommon species of central and north-central Chile. The latitudinal range documented here is at least 4.8° greater than previously reported, extending from ca. 29°S [...]

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 [...]

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 [...]

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

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 [...]

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 [...]

The recent pandemic caused by SARS-Cov-2 has witnessed an evolving succession of variants of the virus. While the phenomenon of invasion by immunity evading variants is known for other viruses such as influenza, the dynamics of the ecological and evolutionary process in the succession is little known. Since during the Covid-19 pandemic, large scale epidemiological data were collected and made [...]

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 [...]

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 [...]

Executive functions are a set of cognitive control processes required for optimizing goal- directed behaviour. Despite more than two centuries of research on executive functions, both in humans and nonhuman animal species, there is still a knowledge gap of what constitutes the mechanistic basis of evolutionary variation in executive function abilities. Here we show experimentally that changes in [...]

1. The literature is awash with studies purporting to show how various species and data characteristics affect the performances of Species Distribution Models (SDMs). Many of these studies follow a similar template: they fit SDMs for several species, or the same species using different datasets; assess the accuracy of those SDMs using skill statistics; and then identify correlates thereof.
