Phylogeographic and phenotypic outcomes of brown anole colonization across the Caribbean provide insight into the beginning stages of an adaptive radiation

Jason J. Kolbe, Richard E. Glor, Marta López‐Darias, C. Verónica Gómez Pourroy, Alexis S. Harrison, Kevin De Queiroz, Liam J. Revell, Jonathan B. Losos & Robert Graham Reynolds
Some of the most important insights into the ecological and evolutionary processes of diversification and speciation have come from studies of island adaptive radiations, yet relatively little research has examined how these radiations initiate. We suggest that Anolis sagrei is a candidate for understanding the origins of the Caribbean Anolis adaptive radiation and how a colonizing anole species begins to undergo allopatric diversification, phenotypic divergence and, potentially, speciation. We undertook a genomic and morphological analysis...

Fock, Didier Gascuel, Luís Gil De Sola, Jan Geert Hiddink, Remment Ter Hofstede, Igor Isajlović, Jónas Páll Jonasson, Ole Jørgensen, Kristján Kristinsson, Gudrun Marteinsdottir, Hicham Masski, Sanja Matić-Skoko, Mark R. Payne, Melita Peharda, Jakup Reinert … & Lilja Stefansdottir
Aim Previous analyses of marine fish species richness based on presence-absence data have shown changes with latitude and average species size, but little is known about the underlying processes. To elucidate these processes we use metabolic, neutral, and descriptive statistical models to analyse how richness responds to maximum species length, fish abundance, temperature, primary production, depth, latitude, and longitude, while accounting for differences in species catchability, sampling effort, and mesh size. Data Results from 53,382...

Data from: Plant defense negates pathogen manipulation of vector behavior

Baiming Liu, Evan L. Preisser, Xiaobin Shi, Huaitong Wu, Chuanyou Li, Wen Xie, Shaoli Wang, Qingjun Wu & Youjun Zhang
1. Although many vector-borne plant pathogens can alter vector behavior to the pathogen's benefit, how plants might counter such manipulation is unknown. 2. In the Tomato yellow leaf curl virus (‘TYLCV’)-Bemisia tabaci-tomato interaction, TYLCV-mediated changes in Bemisia feeding improves viral uptake and transmission. We tested how jasmonic acid (‘JA’), a central regulator of plant anti-herbivore defenses, affected the ability of TYLCV to (A) manipulate Bemisia behavior; and (B) infect plants. 3. Viruliferous Bemisia fed much...

Data from: Satellite telemetry reveals higher fishing mortality rates than previously estimated, suggesting overfishing of an apex marine predator

Michael E. Byrne, Enric Cortés, Jeremy J. Vaudo, Guy C. McN. Harvey, Mark Sampson, Bradley M. Wetherbee & Mahmood Shivji
Overfishing is a primary cause of population declines for many shark species of conservation concern. However, means of obtaining information on fishery interactions and mortality, necessary for the development of successful conservation strategies, are often fisheries-dependent and of questionable quality for many species of commercially exploited pelagic sharks. We used satellite telemetry as a fisheries-independent tool to document fisheries interactions, and quantify fishing mortality of the highly migratory shortfin mako shark (Isurus oxyrinchus) in the...

Data from: Extreme site fidelity as an optimal strategy in an unpredictable and homogeneous environment

Brian D. Gerber, Mevin B. Hooten, Christopher P. Peck, Mindy B. Rice, James H. Gammonley, Anthony D. Apa & Amy J. Davis
1. Animal site fidelity structures space-use, population demography, and ultimately gene flow. Understanding the adaptive selection for site fidelity patterns provides a mechanistic understanding to both spatial and population processes. This can be achieved by linking space-use with environmental variability (spatial and temporal) and demographic parameters. However, rarely is the environmental context that drives the selection for site fidelity behavior fully considered. 2. We use ecological theory to understand whether the spatial and temporal variability...

Attention and distraction in the modular visual system of a jumping spider

Elizabeth Jakob, Margaret Bruce, Daniel Daye, Skye Long, Alex Winsor, Ronald Hoy & Gil Menda
Animals must selectively attend to relevant stimuli and avoid being distracted by unimportant stimuli. Jumping spiders (Salticidae) do this by coordinating eyes with different capabilities. Objects are examined by a pair of high-acuity principal eyes, whose narrow field of view is compensated for by retinal movements. The principal eyes overlap in field of view with motion-sensitive anterior-lateral eyes (ALEs), which direct their gaze to new stimuli. Using a salticid-specific eyetracker, we monitored the gaze direction...

Fishing and habitat condition differentially affect size spectra slopes of coral reef fishes

Paul Carvalho, Fakhrizal Setiawan, Karizma Fahlevy, Beginer Subhan, Hawis Madduppa, Guangyu Zhu & Austin Humphries
Marine food webs are structured through a combination of top-down and bottom-up processes. In coral reef ecosystems, fish size is related to life-history characteristics and size-based indicators can represent the distribution and flow of energy through the food web. Thus, size spectra can be a useful tool for investigating the impacts of both fishing and habitat condition on the health and productivity of coral reef fisheries. In addition, coral reef fisheries are often data-limited and...

GIS rasters to identify sites for creating habitat for American Woodcock in Rhode Island

Bill Buffum
The University of Rhode Island has conducted several studies of habitat use of Scolopax minor (American Woodcock) in Rhode Island, USA. In 2020 we developed a new species distribution model (SDM) tool to identify sites in the Rhode Island where forest clearcutting to create young forest habitat would have the most positive effect for American woodcock. A typical SDM predicts the probability of presence (POP) of a species at any location based on an analysis...

Body shape transformations by alternate anatomical adaptive peak shifts in blenniiform fishes

David Collar, Emma DiPaolo, Sienna Mai & Rita Mehta
Extreme body elongation has occurred repeatedly in the evolutionary history of ray-finned fishes. Lengthening of the anterior-posterior body axis relative to depth and width can involve changes in the cranial skeleton and vertebral column, but to what extent is anatomical evolution determined by selective factors and intrinsic constraints that are shared broadly among closely related lineages? In this study, we fit adaptive (Ornstein-Uhlenbeck) evolutionary models to body shape and its anatomical determinants and identified two...

Data from: Using DNA barcoding to identify host-parasite interactions between cryptic species of goby (Coryphopterus: Gobiidae, Perciformes) and parasitic copepods (Pharodes tortugensis: Chondracanthidae, Cyclopoida)

Graham Forrester, Malachy McCaffrey, Kristina Terpis & Christopher Lane
Previous work, using morphological characters, identified a generalist copepod parasite (Pharodes tortugensis) at high prevalence on two common gobies (Coryphopterus glaucofraenum and C. dicrus) in the British Virgin Islands (BVI). DNA barcoding subsequently revealed C. glaucofraenum to be three morphologically similar species (C. glaucofraenum, C. venezuelae and C. tortugae), casting doubt on host identities in the BVI and the classification of the parasite as a single species. Mitochondrial cytochrome c oxidase subunit I (COI) data...

Malaria vector mosquito images 2

Jannelle Couret
We created a novel database of mosquito images by sampling live mosquitoes from established colonies maintained by the Malaria Research and Reference Reagent Resource (MR4)/ Biodefense and Emerging Infections (BEI) Resources at the Centers for Disease Control and Prevention (CDC) in Atlanta, GA. Adults of both sexes were imaged from 15 species of mosquitoes from there genera, 13 Anopheles, 2 Culex and 1 Aedes. There are a total of 1,709 images. We included an additional...

Cross-seasonal effects in the American Woodcock: conditions prior to fall migration relate to migration strategy and its implications for conservation

Clayton Graham, Tanner Steeves & Scott McWilliams
How post-breeding habitat quality and body composition of migratory birds carry over to influence fall migration strategies and residency merits consideration when creating cross-seasonal conservation plans, especially in breeding populations that are partial migrants. We assessed the influence of post-breeding habitat quality on departure body composition and fall migration patterns in a southern New England breeding population of American Woodcock (Scolopax minor). Woodcock that overwintered near breeding areas (n=5) had less fat upon capture in...

A general method for calculating power for GEE analysis of complete and incomplete stepped wedge cluster randomized trials

Ying Zhang, John S Preisser, Elizabeth L Turner, Paul J Rathouz, Mark Toles & Fan Li
Stepped wedge designs have uni-directional crossovers at randomly assigned time points (steps) where clusters switch from control to intervention condition. Incomplete stepped wedge designs are increasingly used in cluster randomized trials of health care interventions and have periods without data collection due to logistical, resource and patient-centered considerations. The development of sample size formulae for stepped wedge trials has primarily focused on complete designs and continuous responses. Addressing this gap, a general, fast, non-simulation based...

Floral organ transcriptome in Camellia sasanqua provided insight into stamen petaloid

Menglong Fan, Xinlei Li, Ying Zhang, Si Wu, Zhixin Song, Hengfu Yin, Weixin Liu, Zhengqi Fan & Jiyuan Li
Abstract Background The cultivated Camellia sasanqua forms a divergent double flower pattern, and the stamen petaloid is a vital factor in the phenomenon. However, the regulation mechanism remains largely unclear. Results Here, a comprehensive comparative transcriptome analysis of the wild-type, “semi-double”, “peony double”, and “rose double” was performed. The cluster analysis of global gene expression level showed petal and stamen difficulty separable in double flower. The crucial pathway and genes related to double flower patterns...

Data from: Mechanisms of biotic resistance across complex life cycles

Marc Rius, Elaine E. Potter, John J. Stachowicz & J. David Aguirre
1. Biotic resistance is the ability of communities to inhibit the establishment, spread or impact of novel species. However, the interactions that underlie biotic resistance depend heavily on the contexts in which species interact. Consequently, studies of biotic resistance that consider single processes, patches, species or life-history stages may provide an incomplete picture of the capacity for communities to resist invasion. 2. Many organisms have multiphasic life cycles, where individuals can occupy distinct niches at...

Data from: Migrating songbirds on stopover prepare for, and recover from, oxidative challenges posed by long-distance flight

Megan M. Skrip, Ulf Bauchinger, Wolfgang Goymann, Leonida Fusani, Massimiliano Cardinale, Rebecca R. Alan & Scott R. McWilliams
Managing oxidative stress is an important physiological function for all aerobic organisms, particularly during periods of prolonged high metabolic activity, such as long-distance migration across ecological barriers. However, no previous study has investigated the oxidative status of birds at different stages of migration and whether that oxidative status depends on the condition of the birds. In this study, we compared (1) energy stores and circulating oxidative status measures in (a) two species of Neotropical migrants...

Data from: Experimental evolution: assortative mating and sexual selection, independent of local adaptation, lead to reproductive isolation in the nematode Caenorhabditis remanei

Dean M. Castillo, Melissa K. Burger, Curtis M. Lively & Lynda F. Delph
Using experimental evolution, we investigated the contributions of ecological divergence, sexual selection, and genetic drift to the evolution of reproductive isolation in Caenorhabditis remanei. The nematodes were reared on two different environments for 100 generations. They were assayed for fitness on both environments after 30, 64, and 100 generations, and hybrid fitnesses were analyzed after 64 and 100 generations. Mating propensity within and between populations was also analyzed. The design allowed us to determine whether...
