Subjects: Ecology and Evolutionary Biology, Immunology and Infectious Disease, Life Sciences, Marine Biology, Other Ecology and Evolutionary Biology, Statistical Models

Coral reefs are under threat from disease as climate change alters environmental conditions. Rising temperatures exacerbate coral disease, but this relationship is likely complex as other factors also influence coral disease prevalence. To better understand this relationship, we meta-analytically examined 108 studies for changes in global coral disease over time alongside temperature, expressed [...]

Beta diversity of restored river dike grasslands is strongly influenced by uncontrolled spatio-temporal variability

Markus Bauer, Jakob Huber, Johannes Kollmann

Published: 2023-01-20
Subjects: Ecology and Evolutionary Biology

1. Spatio-temporal dynamics of biodiversity are a key measure when monitoring restoration success. Balanced species turnover is aimed at because it increases overall biodiversity and improves ecosystem stability and multifunctionality. For predictive restoration, it is important to analyse spatial beta diversity and to identify its drivers like site characteristics but also uncontrolled factors [...]

The missing link: discerning true from false negatives when sampling species interaction networks

Michael D Catchen, Timothée Poisot, Laura J. Pollock, et al.

Published: 2023-01-19
Subjects: Applied Statistics, Biodiversity, Ecology and Evolutionary Biology, Environmental Monitoring

Ecosystems are composed of networks of interacting species. These interactions allow communities of species to persist through time through both neutral and adaptive processes. Despite their importance, a robust understanding of (and ability to predict and forecast) interactions among species remains elusive. This knowledge-gap is largely driven by a shortfall of data—although species occurrence [...]

Evolutionary Game Theory and the Adaptive Dynamics Approach: Adaptation where Individuals Interact

Piret Avila, Charles Mullon

Published: 2023-01-17
Subjects: Ecology and Evolutionary Biology

Evolutionary game theory and the adaptive dynamics approach have made invaluable contributions to understand how gradual evolution leads to adaptation when individuals interact. Here, we review some of the basic tools that have come out of these contributions to model the evolution of quantitative traits in complex populations. We collect together mathematical expressions that describe [...]

Anti-predator defenses are linked with high levels of genetic differentiation in frogs

Iliana Medina, Caroline Dong, Roberto Marquez, et al.

Published: 2023-01-15
Subjects: Biology, Ecology and Evolutionary Biology

Predator-prey interactions have been suggested as drivers of diversity in different lineages, and the presence of anti-predator defences in some clades is linked to higher rates of diversification. Warning signals are some of the most widespread defenses in the animal world, and there is evidence of higher diversification rates in aposematic lineages. The mechanisms behind such species richness, [...]

Analyzing health of forcibly displaced communities through an integrated ecological lens

Healthcare among forcibly displaced persons is frequently driven by siloed approaches. Aspects of the built environment, social factors, and the bi-directional relationship between the changing ecosystem and residents are often ignored in health policy design and implementation. While recognizing factors that create a preference for siloed approaches and appreciating the work of humanitarian [...]

Like little lagoons: the contribution of valli da pesca to the Ecosystem Services supply of the Venice Lagoon

Alice Stocco, Laura Basconi, Silvia Rova, et al.

Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology

The Venice lagoon social-ecological system is characterized by a strong relationship between the natural environment and human activities. This is especially noticeable in the aquaculture and hunting reserves of the lagoon, locally known as valli da pesca. Previous works about Ecosystem Services (ESs) in the Venice lagoon focused on the so-called “open lagoon”, overlooking the role of the valli [...]

Use of Airborne Laser Scanning to assess effects of understorey vegetation structure on nest-site selection and breeding performance in an Australian passerine bird

Richard S. Turner, Ophélie J. D. Lasne, Kara N. Youngentob, et al.

Published: 2022-12-18
Subjects: Animal Sciences, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Ornithology

In wild bird populations, the structure of vegetation around nest-sites can influence the risk of predation of dependent young offspring, generating selection for breeding birds to choose nest-sites with vegetation characteristics associated with lower predation rates. However, for researchers, vegetation structure can be difficult to quantify objectively in the field, which might explain why [...]

Evaluating top-down, bottom-up, and environmental drivers of pelagic food web dynamics along an estuarine gradient

Tanya L Rogers, Samuel M Bashevkin, Christina E Burdi, et al.

Published: 2022-12-15
Subjects: Aquaculture and Fisheries Life Sciences, Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology

Identification of the key biotic and abiotic drivers within food webs is important for understanding species abundance changes in ecosystems, particularly across ecotones where there may be strong variation in interaction strengths. Using structural equation models and four decades of integrated data from the San Francisco Estuary, we investigated the relative effects of top-down, bottom-up, and [...]

Assessing species interactions using integrated predator-prey models

Matthieu Paquet, Frederic Barraquand

Published: 2022-12-15
Subjects: Biostatistics, Dynamic Systems, Ecology and Evolutionary Biology, Population Biology, Statistical Methodology, Terrestrial and Aquatic Ecology

Inferring the strength of species interactions from demographic data is a challenging task. The Integrated Population Modelling (IPM) approach, bringing together population counts, capture-recapture, and individual-level fecundity data into a unified model framework, has been extended from single species to the community level. This allows to specify IPMs for multiple species with interactions [...]

Habitat destruction threatens jaguars in a mixed land use region of eastern Bolivia

René Meißner, Moritz Blumer, Merlin Weiß, et al.

Published: 2022-12-14
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Zoology

Large carnivores such as the jaguar (Panthera onca) are particularly susceptible to population decline and local extinction as a result of habitat loss. Here, we report on the long-term monitoring of a local jaguar population in a mixed land use area in the eastern lowlands of Bolivia from March 2017 to December 2019. We recorded 15 jaguar individuals and four reproduction events (five offspring [...]

Extracting data from studies is the norm in meta-analyses, enabling researchers to generate effect sizes when raw data are otherwise not available. While there has been a general push for increased reproducibility throughout the many facets of meta-analysis, the transparency and reproducibility of the data extraction phase are still lagging be- hind. This particular meta-analytic facet is [...]

Evolutionary repeatability of emergent properties of ecological communities

Sandeep Venkataram, Sergey Kryazhimskiy

Published: 2022-12-10
Subjects: Ecology and Evolutionary Biology

Most species belong to ecological communities where their interactions give rise to emergent community-level properties, such as diversity and productivity. Understanding and predicting how these properties change over time has been a major goal in ecology, with important practical implications for sustainability and human health. Less attention has been paid to the fact that community-level [...]

Power and limitations of the mutations-area relationship to assess within-species genetic diversity targets for post-2020 Sustainable Development Goals

Moises Exposito-Alonso, Jeffrey Spence, Megan Ruffley, et al.

Published: 2022-12-09
Subjects: Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences

To evaluate the United Nation’s preliminary post-2020 sustainable goals on protecting high levels of genetic diversity per species, Exposito-Alonso et al. (2022) proposed a new framework to predict a species’ loss of genetic diversity given its loss of habitat area. This method, called the mutations-area relationship (MAR), is analogous to the species-area relationship (SAR), often used to assess [...]
