Consideration for Connection between Concrete and Abstract of Living System
Published: 2023-11-28
Subjects: Life Sciences
Living systems are established by the coordination of diverse systems in the environment, are responsive to change, and are stable over time. Many studies and ideas have been proposed on the mechanisms and general laws of living systems from the viewpoints of evolutionary biology, systems biology, and chaos theory. The mechanisms of evolution and coordination of living systems are also related to [...]
Vocal Dimorphism in Anna’s Hummingbirds
Published: 2023-11-28
Subjects: Animal Sciences, Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Integrative Biology, Life Sciences, Ornithology, Zoology
Whereas vocal sexual dimorphism is widespread amongst birds, it has been historically overlooked in non-passerines such as hummingbirds. By evaluating correlations among sex, behaviors, and vocalizations, the meaning and utility of intentional sound production may be inferred. Anna's Hummingbirds (Calypte anna) exhibit pronounced sexual dimorphism, with males being larger and having more vibrant [...]
The costs of extra-pair mating
Published: 2023-11-28
Subjects: Life Sciences
Extra-pair behaviours, where individuals copulate outside of an established pair bond, resulting in extra-pair paternity (EPP) of offspring, have long intrigued behavioural ecologists. Of particular interest is why females of otherwise socially monogamous species engage in extra-pair behaviours. Although researchers recognise that the drivers of variation in EPP, both within-species and [...]

this version should be deleted it is duplicated with the ID 6292 which is the correct version. Please delete this entry. I don't know why you guys have created two entries and this one with a wrong file that reads for review only.
Signal space overlap in sympatric drongos (Aves: Dicruridae) and spatial segregation in a South Asian tropical rainforest
Published: 2023-11-28
Subjects: Life Sciences
A diverse array of animals use a multidimensional acoustic space as a primary source of communication, especially in habitats where other signals are limited. However, in complex habitats, species must contend with other co-occurring species to send their message in a backdrop of ambient noise. This is exacerbated in closely related species that occur in sympatry, and we do not know how species [...]
Opinion: Missing half the picture, focus on stony corals during bleaching events has left critical knowledge gaps in our understanding of reef-scale bleaching and recovery

Honest Signalling Made Simple
Published: 2023-11-24
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
Honest communication is a common phenomenon in animal behaviour, and is frequently explained by appeal to the so-called handicap hypothesis by which signal costs deter dishonesty. However, the handicap models commonly used to explain honest signalling have has been subject to several lines of criticism in recent literature. This trend may have led researchers outside of the field of animal [...]

A pluralistic framework for measuring and stratifying heterogeneity in meta-analyses
Published: 2023-11-24
Subjects: Ecology and Evolutionary Biology, Statistics and Probability
1. Measuring heterogeneity, or inconsistency, among effect sizes is a crucial step for interpreting the meta-analytic evidence across diverse taxonomic groups and spatiotemporal contexts. However, ecologists and evolutionary biologists often interpret mean population effects (i.e., meta-analytic mean effect size) as consistent, either explicitly or implicitly, without proper [...]
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 [...]
Fuentes para el Estudio de la historia de extracción, consumo y comercio de tres especies de aves venezolanas amenazadas
Published: 2023-11-22
Subjects: Agricultural and Resource Economics, Environmental Studies, Natural Resources and Conservation
El comercio y uso de vida silvestre es un problema complejo que se ve afectado por la dinámica temporal y geográfica de las redes de comercio y tráfico que estimulan la extracción y consumo de recursos. Para estudiar la historia de valoración, consumo y tráfico de la cotorra cabeciamarilla (Amazona barbadensis), el cardenalito (Sporagra cucullata) y el paují copete de piedra (Pauxi pauxi) [...]
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 [...]
