DNA metabarcoding as a tool for detecting and characterising the spatio-temporal distribution of planktonic larvae in the phylum Echinodermata
Published: 2023-11-22
Subjects: Life Sciences
Metabarcoding is revolutionising the analysis of biodiversity in marine ecosystems, especially as it provides a means of detecting and identifying cryptic life-stages in field samples. The planktonic larval stage of many species underpins the abundance and distribution of adult populations but is challenging to characterise given the small size of larvae and diffuse distributions in pelagic [...]
Amazonian soundscapes: unravelling the secrets of insect acoustic niches in diverse habitats
Published: 2023-11-22
Subjects: Ecology and Evolutionary Biology
Insects are the most diverse animal taxon on Earth and play a key role in ecosystem functioning. However, they are often neglected from biodiversity surveys due to the difficulties of monitoring this small and hyper-diverse taxon. With technological advancements in biomonitoring and analytical methods, these shortcomings may finally be addressed. Here, we performed passive acoustic monitoring at [...]

Local and regional processes drive distance decay in structure in a spatial multilayer plant-pollinator network
Published: 2023-11-21
Subjects: Ecology and Evolutionary Biology, Life Sciences
Understanding spatial variation in species distribution and community structure is at the core of biogeography and community ecology. Nevertheless, the effect of distance on metacommunity structure remains little studied. We use plant-pollinator network data from the Canary Islands to examine how plant-pollinator community structure changes across geographical distances at a regional scale and [...]
Covariance reaction norms: A flexible method for estimating complex environmental effects on trait (co)variances
Published: 2023-11-21
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Evolution, Genetics, Integrative Biology, Life Sciences, Population Biology, Research Methods in Life Sciences, Zoology
Estimating quantitative genetic and phenotypic (co)variances is crucial for investigating evolutionary ecological phenomena such as developmental integration, life history tradeoffs, and niche specialization, as well as for describing selection and predicting multivariate evolution in the wild. While most studies assume (co)variances are fixed over short timescales, environmental heterogeneity [...]
Global Distribution of Vascular Epiphyte Diversity
Published: 2023-11-20
Subjects: Life Sciences
Epiphytes are a large and understudied part of global diversity. Classic work by Gentry and Dodson argued that Neotropical, mid-elevation forests are centers of diversity for this growth form. We assessed this hypothesis with modern global geospatial and climatic datasets. By connecting growth form and occurrence data with climatic records at the same locations, we quantified spatial and climatic [...]
Sex-specific associations between social behaviour, its predictability and fitness in a wild lizard
Published: 2023-11-20
Subjects: Behavior and Ethology
Social environments impose a number of constraints on individuals’ behaviour. These constraints have been hypothesized to generate behavioural variation among individuals, social responsiveness, and within-individual behavioural consistency (also termed ‘predictability’). In particular, the social niche specialization hypothesis posits that higher levels of competition [...]

Octocoral Symbiodiniaceae, but not bacterial communities, are resistant to compositional changes from heat stress on a subtropical reef
Published: 2023-11-20
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Other Ecology and Evolutionary Biology
Microbes are essential to the holobiome of all organisms, so when organisms are impacted by environmental stressors the changes to microbial communities can inform on the health state of the host and even cause host disease. In early 2019 marine heatwaves occurred across eastern Australia, resulting in differential bleaching across Lord Howe Island reefs. Here we examined the Symbiodiniaceae and [...]

Behavioural and trophic variation within a well-established invasive round goby population
Published: 2023-11-20
Subjects: Life Sciences
An animal’s behavioural traits can influence the outcomes of ecological interactions within their food-web, including what they eat, their vulnerability to predation and who they compete with. Despite this, few studies have directly measured links between among-individual behavioural and trophic variation. Invasive species like the round goby (Neogobius melanostomus) are often found to have [...]
Extreme events and coupled socio-ecological systems
Published: 2023-11-20
Subjects: Agricultural and Resource Economics, Behavioral Economics, Demography, Population, and Ecology, Ecology and Evolutionary Biology, Human Ecology, Life Sciences, Marine Biology, Other Social and Behavioral Sciences, Social and Behavioral Sciences
Rare, but potentially impactful, extreme events in socio-ecological systems (SES) can trigger significant consequences. The scarcity of theoretical frameworks for such events in SES is due to data limitations and difficulty in building coupled SES models. We explore the effect of extreme events on coupled socio-ecological systems using two stylized case studies: harvesting of old-growth forests [...]
