Same data, different analysts: variation in effect sizes due to analytical decisions in ecology and evolutionary biology

Elliot Gould, Hannah S. Fraser, Timothy H Parker, et al.

Published: 2023-10-04
Subjects: Ecology and Evolutionary Biology, Life Sciences, Research Methods in Life Sciences

Although variation in effect sizes and predicted values among studies of similar phenomena is inevitable, such variation far exceeds what might be produced by sampling error alone. One possible explanation for variation among results is differences among researchers in the decisions they make regarding statistical analyses. A growing array of studies has explored this analytical variability in [...]

The ecomorphological diversity of Amazonian stream fishes is constrained by phylogenetic relationships

Bruno Eleres Soares, Naraiana L. Benone, Rafael P. Leitão, et al.

Published: 2023-09-30
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences

Phylogenetic history and environmental conditions determine trait diversity of species pools. Stream fishes have diversified into a wide range of body and oral shapes that allow a similarly wide range of functional traits that are related to resource use and phylogenetic closeness. Herein, we analyzed 16 ecomorphological traits of nearly 400 fishes inhabiting streams distributed across the [...]

Don’t make genetic data disposable: Best practices for genetic and genomic data archiving

Deborah M Leigh, Amy Vandergast, Maggie Hunter, et al.

Published: 2023-09-25
Subjects: Bioinformatics, Biology, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences

In ecology and evolution, genetic and genomic data are commonly collected for a vast array of scientific and applied purposes. Despite mandates for public archiving, such data are typically used only once by the data-generating authors. The repurposing of genetic and genomic datasets remains uncommon because it is often difficult, if not impossible, due to non-standard archiving practices and [...]

Functional trait dataset of benthic macroinvertebrates in South Korean streams

Sagar Adhurya, Da-Yeong Lee, Dae-Seong Lee, et al.

Published: 2023-09-22
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology

Functional traits are the result of evolution and adaptation, providing important ecological insights into how organisms interact with their environment. Benthic macroinvertebrates, in particular, have garnered attention as biomonitoring indicators for freshwater ecosystems. This study presents a functional trait dataset for benthic macroinvertebrates, comprising 447 taxa (393 at genus level, 53 [...]

Metaweb and its applications in understanding ecological interactions

Sagar Adhurya, Nisha Agasti, Young-seuk Park

Published: 2023-09-22
Subjects: Ecology and Evolutionary Biology, Other Ecology and Evolutionary Biology

Understanding the dynamics of ecological interactions is an essential initial step in acquiring a comprehensive understanding of the ecosystem structure and functions. Such knowledge is pivotal in effective conservation planning, sustainable development, and ecosystem management. However, the limited availability of information on ecological interactions, commonly referred to as Eltonian [...]

Time since first naturalization is key to explaining non-native plant invasions on islands

Fabio Mologni, Peter J. Bellingham, Ewen K. Cameron, et al.

Published: 2023-09-19
Subjects: Ecology and Evolutionary Biology

Aim Investigating the extent of insular invasions by non-native species (i.e. the number of islands they occupy) is central to island conservation. However, interrelationships among plant life history traits, naturalization histories, and island characteristics in determining island occupancy by non-native plant species are poorly understood. We investigated whether island occupancy by different [...]

A global analysis reveals the dynamic relationship between sexual selection and population abundance in space and time

Joshua Markovski, Corey T Callaghan, William K Cornwell, et al.

Published: 2023-09-17
Subjects: Ecology and Evolutionary Biology, Evolution

Sexual selection leads to the evolution of extravagant weaponry or ornamental displays, with the bearer of these traits gaining a reproductive advantage, potentially at a cost to the individual’s survival. The consequences of sexual selection can therefore impact species demographic processes and overall abundance. Currently, evidence connecting the effects of sexual selection to demography and [...]

Spatially explicit predictions of food web structure from regional level data

Gabriel Dansereau, Ceres Barros, Timothée Poisot

Published: 2023-09-15
Subjects: Biodiversity, Ecology and Evolutionary Biology

Knowledge about how ecological networks vary across global scales is currently limited given the complexity of acquiring repeated spatial data for species interactions. Yet, recent developments of metawebs highlight efficient ways to first document possible interactions within regional species pools. Downscaling metawebs towards local network predictions is a promising approach to use current [...]

Lasting effects of avian-frugivore interactions on seed dispersal and seedling establishment

Elena Quintero, Juan M. Arroyo, Rodolfo Dirzo, et al.

Published: 2023-09-13
Subjects: Ecology and Evolutionary Biology, Life Sciences

1. The consequences of plant-animal interactions often transcend the mere encounter stage, as those encounters are followed by a chain of subsequent stages on the plant’s reproductive cycle that ultimately determine fitness. Yet, the dissemination and recruitment stages of animal-mediated seed dispersal are seldom analysed jointly, hindering a full understanding of the ecology of seed [...]

Taming the terminological tempest in invasion science

Ismael Soto Almena, Paride Balzani, Lais Carneiro, et al.

Published: 2023-09-06
Subjects: Ecology and Evolutionary Biology

Standardized terminology in science is important for clarity of interpretation and communication. In invasion science — a dynamic and quickly evolving discipline — the rapid proliferation of technical terminology has lacked a standardized framework for its language development. The result is a convoluted and inconsistent usage of terminology, with various discrepancies in descriptions of damages [...]

Re-defining common mycorrhizal and fungal networks

Matthias C. Rillig, Anika Lehmann, Luisa Lanfranco, et al.

Published: 2023-09-06
Subjects: Ecology and Evolutionary Biology, Life Sciences, Plant Sciences

The current use of the term ‘common mycorrhizal network’ (CMN) stipulates a direct link between plants formed by the mycelium of a mycorrhizal fungus. This means that a specific case (involving hyphal continuity) is used to define a much broader phenomenon of hyphae interlinking among plant roots. We here offer a more inclusive definition of the common mycorrhizal network as a network formed by a [...]

Growth and opportunities for drone surveillance in pinniped research

Pinniped species undergo uniquely amphibious life histories that make them valuable subjects for many domains of research. Pinniped research has often progressed hand-in-hand with technological frontiers of wildlife biology, and drones represent a leap forward for methods of aerial remote sensing, heralding data collection and integration at new scales of biological importance. Drone methods and [...]
