Dung beetles are known to carry out a range of ecosystem functions such as secondary seed dispersal, bioturbation, nutrient cycling, plant growth, pest and parasite control, and trophic regulation, many of which support key ecosystem services. Despite the globally purported significance of this group of insects for ecosystem functioning, there has been no quantitative synthesis to establish the [...]

Developmental axioms in life history evolution

Liam U Taylor, Richard Prum

Published: 2023-12-14
Subjects: Ecology and Evolutionary Biology, Evolution

Life history theory is often invoked to make universal predictions about phenotypic evolution. For example, it is conventional wisdom that organisms should evolve older ages at first reproduction if they have longer lifespans. We clarify that life history theory does not currently provide such universal predictions about phenotypic diversity. Using the classic Euler-Lotka model of adaptive life [...]

Subjects: Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Life Sciences, Soil Science

Arbuscular mycorrhizal (AM) associations are multifunctional. Two important functions they perform are facilitating nutrient uptake in host plants and protecting plants from biotic stress, among other functions. AM fungal taxa vary in how capably they perform these functions and can also respond differently to environmental selection. Therefore, there is a need to better understand how particular [...]

Bird species’ centrality in seed-dispersal networks varies within climatic niches

Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences

Understanding how the functional role of species within seed-dispersal networks varies across geographical and climatic gradients can reveal the mechanisms driving network organization. Using data for 157 bird species from all continents, we evaluated the variation of species’ centrality within local networks across species’ climatic niches (occupied climatic conditions) and in response to [...]

A user-friendly AI workflow for customised wildlife-image classification

Monitoring wildlife is crucial for making informed conservation and land-management decisions. Remotely triggered cameras are widely used for this, but the resulting 'big data' are laborious to process. Artificial intelligence (AI) offers a solution to this bottleneck, but it has been challenging for ecologists and practitioners to tailor current approaches to their specific use cases. Generic, [...]

Urbanization alters sandy beach scavenging assemblages but not ecosystem function

Species delimitation is the process of distinguishing between populations of the same species and distinct species of a particular group of organisms. Various methods exist for inferring species limits, with most of them being rooted in Coalescent Theory. Their primary goal is to identify independently evolving lineages that should represent separate species. Coalescent models have improved [...]

Legacy effects describe the persistent, long-term impacts on an ecosystem following the removal of an abiotic or biotic feature. Redlining, a policy that codified racial segregation and disinvestment in minoritized neighborhoods, has produced legacy effects with profound impacts on urban ecosystem structure and health. These legacies have detrimentally impacted public health outcomes, [...]

Detecting context-dependence in the expression of demographic tradeoffs

Louis Bliard, Jordan Scott Martin, Maria Paniw, et al.

Published: 2023-12-07
Subjects: Ecology and Evolutionary Biology, Evolution, Population Biology

Life history tradeoffs are one of the central tenets of evolutionary demography. Tradeoffs, depicting negative phenotypic or genetic covariances between individuals’ demographic rates, arise from a finite amount of resources that each individual has to allocate in a zero-sum game between somatic and reproductive functions. While theory predicts that tradeoffs are ubiquitous, empirical studies [...]
