Space-for-time substitutions in climate change ecology and evolution
Published: 2022-11-09
Subjects: Ecology and Evolutionary Biology
In an epoch of rapid environmental change, understanding and predicting how biodiversity will respond to a changing climate is an urgent challenge. Since we seldom have sufficient long-term biological data to use the past to anticipate the future, spatial climate-biotic relationships are often used as a proxy for predicting biotic responses to climate change over time. These ‘space-for-time [...]
Heritability and developmental plasticity of growth in an oviparous lizard
Published: 2022-11-09
Subjects: Ecology and Evolutionary Biology
Selective processes act on phenotypic variation although the evolutionary potential of a trait relies on the underlying heritable variation. Developmental plasticity is an important source of phenotypic variation, but it can also promote changes in genetic variation, yet we have a limited understanding on how they are both impacted. Here, we quantified the influence of developmental temperature [...]
Colombia reached 30 % of land and ocean conservation area. Megadiverse countries are hitting targets but missing the point
Published: 2022-11-08
Subjects: Life Sciences
The global target to protect 30% of Earth’s land and ocean by 2030 has prompted governments to report their progress in biodiversity conservation. Announcements of countries reaching 30 % of conservation area are widely commended by the international community, despite signs of increasing pressures within protected areas, poor representativity of key threatened ecosystems, and a lack of [...]
Evolutionary origins of the Mesoamerican-eastern United States floristic disjunction: current status and future prospects
Published: 2022-11-07
Subjects: Biodiversity, Biology, Botany, Ecology and Evolutionary Biology, Evolution, Life Sciences, Plant Sciences
Biogeographic disjunction patterns, where multiple taxonomic groups are shared between isolated geographic areas, represent excellent systems for investigating the historical assembly of modern biotas as well as fundamental biological processes such as speciation, diversification, niche evolution, and evolutionary responses to climate change. Studies on plant genera disjunct across the Northern [...]
The Fieldwork Wellness Framework: A new approach to field research in Ecology
Published: 2022-11-07
Subjects: Biology, Ecology and Evolutionary Biology
Fieldwork is often an important aspect of research in Ecology, Evolution, and Conservation Biology (EECB), but individuals with marginalized identities are likely to experience compromised wellness. The responsibility for structurally changing fieldwork to improve experiences and outcomes falls on the entire EECB community. We propose a Fieldwork Wellness Framework to replace traditional [...]
The intersection between elected representatives and threatened species recovery
Published: 2022-11-05
Subjects: Environmental Sciences, Geography, Political Science
A core objective of the conservation movement is to motivate government decision-makers into delivering critical policy changes to abate the global species extinction crisis. Using Australia as a case study, we showcase a way of highlighting the intersection between a nation’s elected representatives and extant threatened species. We analyse the relationship between Australia’s 151 Commonwealth [...]
CONFOUND IT! The taxonomy of plants mistaken for Cistanthe arenaria (Cham.) Carolin ex Hershk. [MONTIACEAE, Cistanthe sect. Rosulatae (Reiche) Hershk.]
Published: 2022-11-04
Subjects: Biodiversity, Life Sciences
Cistanthe arenaria (Cham.) Carolin ex Hershk. is a species of Montiaceae distributed from Chile’s Maule to Araucanía Regions. But the name historically and currently has been applied also to readily distinct species distributed from the Libertador Bernardo O’Higgins to Coquimbo Regions: C. chamissoi (Barnéoud) Carolin ex Hershk., C. trigona (Bertero ex Colla) Carolin ex Hershk, C. [...]
The consequences of synthetic auxin herbicide on plant-herbivore interactions
Published: 2022-11-03
Subjects: Life Sciences
Although herbicide drift is a common side effect of herbicide application in agroecosystems, its effects on the ecology and evolution of natural communities are rarely studied. A recent shift to dicamba, a synthetic auxin herbicide known for ‘drifting’ to nontarget areas necessitates the examination of drift effects on the plant-insect interactions that drive eco-evo dynamics in weed communities. [...]
Assessing the aesthetic attractivity of European butterflies: a web-based survey protocol
Published: 2022-11-03
Subjects: Biodiversity, Entomology, Life Sciences, Zoology
Aesthetic attractivity stands as an underestimated yet fundamental feature of species in conservation biology, significantly driving disproportionate protection efforts towards charismatic species. Despite the evidence, few attempts sought to precisely quantify the impact of aesthetic attractivity in defining priority of species for conservation actions (e.g. inclusion in International Union for [...]
Unstratified forests dominate the tropics especially in regions with lower fertility or higher temperatures
Published: 2022-11-02
Subjects: Biodiversity, Forest Biology, Plant Biology
The stratified nature of tropical forest structure had been noted by early explorers, but until recent use of satellite-based LiDAR (GEDI, or Global Ecosystems Dynamics Investigation LiDAR), there has been no way to quantify stratification across all tropical forests. Understanding stratification is important because by some estimates, a majority of the world’s species inhabit tropical forest [...]
Small is big: A new conservation paradigm for amphibians
Published: 2022-11-02
Subjects: Biodiversity, Other Ecology and Evolutionary Biology
Many countries have responded to the current global biodiversity crisis by committing to protect 30% of the Earth by 2030, a goal known as “30 x 30”. However, an excessive emphasis on megafauna to the exclusion of other species weakens our current protected area (PA) network. This limited perspective overvalues large, connected PAs, while disregarding the potential impacts of small PAs in [...]
Iterative species distribution modeling results in the discovery of novel populations of a rare cold desert perennial
Published: 2022-11-02
Subjects: Ecology and Evolutionary Biology, Life Sciences
Niche modeling for rare and range-restricted species can generate inaccurate predictions leading to an overestimation of a species geographic distribution. We used an iterative ensemble modeling approach and model-stratified field surveys to improve niche model formulation and better understand the ecological drivers of Ivesia webberi distribution. I. webberi is a U.S. federally threatened [...]
Incompatibility and interchangeability in molecular evolution
Published: 2022-11-02
Subjects: Evolution, Life Sciences, Molecular Genetics
There is remarkable variation in the rate at which genetic incompatibilities in molecular interactions accumulate. In some cases, minor changes – even single nucleotide substitutions – create major epistatic incompatibilities when hybridization forces new variants to function in a novel genetic background from an isolated population. In other cases, genes or even entire functional pathways can be [...]
Temperate-tropical transitions are linked with shifts in the structure of evolutionary integration in Vitaceae leaves
Published: 2022-11-01
Subjects: Ecology and Evolutionary Biology, Life Sciences
Understanding how the intrinsic ability of populations and species to meet shifting selective demands shapes evolutionary patterns over both short and long timescales is a major question in biology. One major axis of evolutionary flexibility can be measured by phenotypic integration and modularity. The strength, scale, and structure of integration may constrain or catalyze evolution in the face [...]
Rapid literature mapping on the recent use of machine learning for wildlife imagery
Published: 2022-10-31
Subjects: Life Sciences
1. Machine (especially deep) learning algorithms are changing the way wildlife imagery is processed. They dramatically speed up the time to detect, count, classify animals and their behaviours. Yet, we currently have a very few systematic literature surveys on its use in wildlife imagery. 2. Through a literature survey (a ‘rapid’ review) and bibliometric mapping, we explored its use across: 1) [...]
