Phenotypic traits are often integrated into evolutionary modules: sets of organismal parts that evolve together. In social insect colonies the concepts of integration and modularity apply to sets of traits both within and among functionally and phenotypically differentiated castes. On macroevolutionary timescales, patterns of integration and modularity within and across castes can be clues to the selective and ecological factors shaping their evolution and diversification. We develop a set of hypotheses describing contrasting patterns of...
Data from: A new versatile primer set targeting a short fragment of the mitochondrial COI region for metabarcoding metazoan diversity: application for characterizing coral reef fish gut contentsMatthieu Leray, Joy Y. Yang, Christopher P. Meyer, Suzanne C. Mills, Natalia Agudelo, Ranwez Vincent, Joel T. Boehm & Ryuji J. Machida
Introduction: The PCR-based analysis of homologous genes has become one of the most powerful approaches for species detection and identification, particularly with the recent availability of Next Generation Sequencing platforms (NGS) making it possible to identify species composition from a broad range of environmental samples. Identifying species from these samples relies on the ability to match sequences with reference barcodes for taxonomic identification. Unfortunately, most studies of environmental samples have targeted ribosomal markers, despite the...
Background: Centromeres are essential for accurate chromosome segregation, yet sequence conservation is low even among closely related species. Centromere drive predicts rapid turnover because some centromeric sequences may compete better than others during female meiosis. In addition to sequence composition, longer centromeres may have a transmission advantage. Results: We report the first observations of extremely long centromeres, covering on average 34 % of the chromosomes, in the red imported fire ant Solenopsis invicta. By comparison,...
Social rank modulates how environmental quality influences cooperation and conflict within animal societiesMark Liu, Bo-Fei Chen, Dustin Rubenstein & Sheng-Feng Shen
Although dominance hierarchies occur in most societies, our understanding of how these power structures influence individual investment in cooperative and competitive behaviors remains elusive. Both conflict and cooperation in animal societies are often environmentally-regulated, yet how individuals alter their cooperative and competitive investments as environmental quality changes remains unclear. Using game theoretic modeling, we predict that individuals of all ranks will invest more in cooperation and less in social conflict in harsh environments than individuals...
Both anthropogenic impacts and historical climate change could contribute to population decline and species extinction, but their relative importance has yet to be determined. Emerging approaches based on genomic, climatic and anthropogenic data provide a promising analytical framework to address this question. This study applied such an integrative approach to examine potential drivers for endangerment of the green peafowl (Pavo muticus). Several demographic reconstructions based on population genomes congruently retrieved a drastic population declination since...
Source data for: Antagonistic effects of intraspecific cooperation and interspecific competition on thermal performanceSheng-Feng Shen, Hsiang-Yu Tsai, Dustin Rubenstein, Bo-Fei Chen, Mark Liu, Shih-Fan Chan, De-Pei Chen, Syuan-Jyun Sun & Tzu-Neng Yuan
Understanding how climate-mediated biotic interactions shape thermal niche width is critical in an era of global change. Yet, most previous work on thermal niches has ignored detailed mechanistic information about the relationship between temperature and organismal performance, which can be described by a thermal performance curve. Here, we develop a model that predicts the width of thermal performance curves will be narrower in the presence of interspecific competitors, causing a species’ optimal breeding temperature to...
The Point Intercept Transect (PIT) method has commonly been used in recent decades for estimating the status of coral reef benthic communities. It is a simple method that is efficiently performed underwater, as benthic components are recorded only as presence or absence at specific interval points along transects. Therefore, PIT is also popular in citizen science activities such as Reef Check programs. Longer intervals are commonly associated with longer transects, yet sampling interval length can...
Higher temperature variability in deforested mountain regions impacts the competitive advantage of nocturnal speciesSheng-Feng Shen, Shih-Fan Chan, Dustin R. Rubenstein, I-Ching Chen, Yu-Meng Fan & Yuan-Wen Zheng
Deforestation is a primary cause of biodiversity loss. However, we know little about its effects on global patterns of daily microclimate variation, which can differentially impact species with different daily activity patterns. Using a recently developed microclimate model, we show that deforestation causes an increase in the diurnal temperature range (DTR) in lowland habitats at low latitudes and the mountains at high latitudes. Furthermore, we investigate competitive interactions between nocturnal burying beetles and all-day active...
