Climate Does Not Predict Thermal and Hydric Traits in Northern Australian Geckos
Published: 2024-06-18
Subjects: Life Sciences
1. Reptiles are challenged with maintaining stable hydric states and viable body temperatures in a variable terrestrial environment. Reptiles can use behaviour to select favourable microhabitats as well as physiological adaptations, such as increased skin resistance to water loss to regulate their hydric and thermal states. The degree to which a species’ physiology is adapted to overcome [...]
Predator activity, proactive anti-predator strategies, and nesting phenology produce a dynamic landscape of risk to tundra goose reproduction
Published: 2024-06-15
Subjects: Ecology and Evolutionary Biology, Life Sciences
Birds generally rely on proactive anti-predator strategies when selecting nest sites, as they have limited options to adapt to changing levels of risk once incubation begins. Arctic waterfowl often nest colonially as an anti-predator strategy but dispersed-breeding species may use other proactive strategies, such as nesting in less risky areas. However, empirical links between spatial patterns of [...]
Biodiversity indicators miss local and short-term change: A blank space waiting to be filled
Published: 2024-06-14
Subjects: Biodiversity, Ecology and Evolutionary Biology
The year 2030 is rapidly approaching. Building, monitoring, and reporting indicators to evaluate the 2030 targets in the Kunming-Montreal Global Biodiversity Framework (GBF) is a major challenge that requires, at minimum, nations to assess their progress at least once within the next five years. To effectively capture this progress, we need indicators that capture fast-paced, on-the-ground [...]
Did organs precede organisms in the dawn of life?
Published: 2024-06-14
Subjects: Life Sciences
Evolutionary processes acting on molecule populations and their assemblies preceded the origin of living organisms. These prebiotic world entities were (re)produced; that is, independently produced by the assembly of their components, following an iterative process giving rise to identical entities, recalling the progeny resulting from self-reproduction. Before the dawn of life, natural selection [...]
The promise of community-driven preprints in ecology and evolution
Published: 2024-06-14
Subjects: Ecology and Evolutionary Biology, Life Sciences
Publishing preprints is quickly becoming commonplace in ecology and evolutionary biology. Preprints can facilitate the rapid sharing of scientific knowledge establishing precedence and enabling feedback from the research community before peer review. Yet, significant barriers to preprint use exist including language barriers, a lack of understanding about the benefits of preprints and a lack of [...]
Sedimentary ancient DNA reveals Neolithic pastoralism and plant community interactions at Southern European high altitudes
Published: 2024-06-13
Subjects: Life Sciences
The Neolithization process introduced significant ecological impacts, especially in Mediterranean mountain areas. We generated a comprehensive sedimentary ancient DNA record from the central Pyrenees, spanning 12.2 to 1.3 ka BP, revealing the earliest continuous presence of sheep (6.5 ka BP) and cattle (5.9 ka BP) in alpine southern Europe. This evidence suggests pastoralism nearly concurred with [...]
Influence of intermittent stream dynamics on predator-prey interactions
Published: 2024-06-13
Subjects: Life Sciences
Intermittent rivers and ephemeral streams are dynamic ecosystems characterized by periodic interruptions in flow, leading to temporary or complete absence of water. These dynamics create a mosaic of isolated pools, reducing habitat volume and connectivity, and impacting resource availability and predation levels. This study addresses three key questions: (i) Do species composition and [...]
The "Conhecimento Brasil" Program neglects the structural problems of Brazilian science and fails to offer a solution to the brain drain
Published: 2024-06-12
Subjects: Science and Technology Studies
We, a group of Brazilian scientists residing abroad in diverse career stages, are writing in response to CNPq’s recent announcement of the "Talent Repatriation Program - Conhecimento Brasil," (see Morimoto 2024). We discuss our impressions and suggestions to align the proposal with what the program aims to achieve.
Trophic generalism in the winter moth: a model system for phenological mismatch
Published: 2024-06-11
Subjects: Life Sciences
Climate change has the potential to disrupt phenological synchrony among interacting species that vary in their phenological sensitivity to temperature. The phenological synchrony observed between winter moth Operophtera brumata caterpillars and oak leafing in spring has become an emblematic test case of this phenomenon, with caterpillars seemingly advancing their phenology more than their [...]
Quantifying life-history trade-offs in diameter growth for tropical tree species from a large urban inventory dataset
Published: 2024-06-11
Subjects: Forest Biology, Forest Management, Horticulture, Integrative Biology, Plant Biology, Population Biology
Trees are important ecosystem service providers that improve the physical environment and human experience in cities throughout the world. Since the ecosystem services and maintenance requirements of urban trees change as they grow in time, predictive models of tree growth rates are useful to forecast societal benefits and maintenance costs over a tree’s lifetime. However, many models to date are [...]
Making use of spatially biased variables in ecosystem condition accounting – a GIS based workflow
Published: 2024-06-07
Subjects: Ecology and Evolutionary Biology, Environmental Indicators and Impact Assessment, Environmental Monitoring
Ecosystem Condition Accounts (ECA) should reflect the integrity or quality of all nature inside the scope of the account, and therefore rely on spatially representative indicators for condition. All ECAs are subject to data constraints in some way. Therefore, being able to make use of spatially biased data sets would be very valuable. For national ECAs, modelling approaches can in some cases be [...]
Behavioral flexibility is similar in two closely related species where only one is rapidly expanding its geographic range
Published: 2024-06-06
Subjects: Behavior and Ethology, Biology, Comparative Psychology, Ecology and Evolutionary Biology, Life Sciences, Population Biology
Human modified environments are rapidly increasing, which puts other species in the precarious position of either adapting to a new area or, if they are not able to adapt, shifting their range to a more suitable environment. It is generally thought that behavioral flexibility, the ability to change behavior when circumstances change, plays an important role in the ability of a species to rapidly [...]
Global metrics for terrestrial biodiversity
Published: 2024-06-06
Subjects: Biodiversity, Environmental Indicators and Impact Assessment, Environmental Monitoring, Life Sciences, Natural Resources and Conservation
Biodiversity metrics are increasingly in demand for informing government, business, and civil society decisions. However, it is not always clear to end users how these metrics differ or for what purpose they are best suited. We seek to answer these questions using a database of 573 biodiversity-related metrics, indicators, indices, and layers, which address aspects of genetic diversity, species, [...]
Tail-dependence of masting synchrony results in continent-wide seed scarcity
Published: 2024-06-06
Subjects: Ecology and Evolutionary Biology, Life Sciences
Spatial synchrony may be tail-dependent, meaning it is stronger for peaks rather than troughs, or vice versa. High interannual variation in seed production in perennial plants, called masting, can be synchronized at subcontinental scales, triggering extensive resource pulses or famines. We used data from 99 populations of European beech (\emph{Fagus sylvatica}) to examine whether masting [...]
Testing for efficacy in four measures of demographic buffering
Published: 2024-06-06
Subjects: Life Sciences
Understanding population responses to variable environments is central to much of current research in population ecology and conservation biology. Environmental variability, a key component of global climate change, increases the extinction risk of species across the tree of life. Therefore, quantifying the sensitivity of populations to environmental variability is timely in the face of global [...]
