Data for A chromosome-level genome assembly for the Eastern Fence Lizard (Sceloporus undulatus), a reptile model for physiological and evolutionary ecology
(2021-04-16)
Background: High-quality genomic resources facilitate investigations into behavioral ecology, morphological and physiological adaptations, and the evolution of genomic architecture. Lizards in the genus Sceloporus have a ...
Images of natural comb

Heat-induced maternal effects shapes avian eggshell traits and embryo response to high temperatures
(2021-03-29)
Populations without a sufficient rate of genetic adaptation may risk extinction in the face of rapid environmental change, however, phenotypic plasticity can facilitate their persistence. For example, mothers can prepare ...
Increased cellular free cholesterol in macrophage-specific Abca1 knock-out mice enhances pro-inflammatory response of macrophages
(2021-03-23)
Macrophage-specific Abca1 knock-out (Abca1(-M/-M)) mice were generated to determine the role of macrophage ABCA1 expression in plasma lipoprotein concentrations and the innate immune response of macrophages. Plasma lipid ...
Data from: Dumpsters and other human structures as habitat for invasive African rock agama lizards in Florida
(2021-03-22)
Invasive species often use habitat differently than native species and can benefit by using underutilized habitats during the invasion process. The Peter’s Rock Agama (Agama picticauda) — native to savannahs of sub-Saharan ...
Politics a "Chilly" Environment for Undergraduate Women in Norway
(2021-03-22)
Gender differences in academic performance and attitudes are widespread in male-stereotyped disciplines but rarely are studied in the social sciences. To assess the extent that gender influences the behavior of undergraduate ...
Indirect Impacts of Recreational Scuba Diving: Patterns of Growth and Predation in Branching Stony Corals
(2021-01-27)
The highest recorded rates of recreational SCUBA diving occur on coral reefs
at Eilat in the northern Red Sea, where many scleractinian corals are damaged by
physical contact with divers. We compared coral skeletal growth ...
Anatomy of the Laminar Organs of Commelina erecta (Commelinaceae)
(2021-01-27)
A study was undertaken to compare the anatomy of the laminar floral parts with that of the spathes and leaves of Commelina erecta L. Each flower has two types of petals and two types of sepals. In contrast to the other ...
Data for: Ecologically relevant thermal fluctuations enhance offspring fitness: biological and methodological implications for studies of thermal developmental plasticity
(2020-08-03)
Natural thermal environments are notably complex and challenging to mimic in controlled studies. Consequently, our understanding of the ecological relevance and underlying mechanisms of organismal responses to thermal ...
Rapid evolution of disease resistance is accompanied by functional changes in gene expression in a wild bird
(2020-06-03)
Wild organisms are under increasing pressure to adapt rapidly to environmental changes. Predicting the impact of these changes on natural populations requires an understanding of the speed with which adaptive phenotypes ...
Reproductive Value and the Stochastic Demography of Age-Structured Populations
(2020-06-03)
The dynamics of an age-structured population in a fluctuating environment is determined by the stochastic individual contributions from annual survival and fecundity to the total reproductive value of the population the ...
Longitudinal Analysis of a Diversity Support Program in Biology: A National Call for Further Assessment
(2020-05-26)
National calls to improve the performance and persistence of students from historically underrepresented backgrounds in science have led to a surge of research on inclusive, evidence-based teaching methods. Less work has ...
With Big Data Comes Big Responsibilities for Science Equity Research
(2020-05-26)
Our ability to collect and access large quantities of data over the last decade has been revolutionary for many social sciences. Suddenly, it is possible to measure human behavior, performance, and activity on an unprecedented ...
Discovery and broad relevance may be insignificant components of course-based 1 undergraduate research experiences (CUREs) for non-biology majors
(2020-05-26)
Course-based undergraduate research experiences (CUREs) are a type of laboratory learning environment associated with a science course in which undergraduates participate in novel research. According to Auchinchloss et ...
Contrasting evolution of virulence and replication rate in an emerging bacterial pathogen
(2020-05-26)
Host resistance through immune clearance is predicted to favor pathogens that are able to transmit faster and are hence more virulent. Increasing pathogen virulence is, in turn, typically assumed to be mediated by increasing ...
Evolution of life histories along elevational gradients: Trade-off between parental care and fecundity
(2020-04-20)
Life history responses to environmental conditions include a combination of fecundity-survival schedules and behavioral strategies that yield the highest fitness in a given environment. In this study, we examined the pattern ...
Direct and indirect genetic and fine-scale location effects on breeding date in song sparrows
(2020-04-02)
1. Quantifying direct and indirect genetic effects of interacting females and males on variation in jointly expressed life-history traits is central to predicting microevolutionary dynamics. However, accurately estimating ...
Functional Characterization of Neuroendocrine Regulation of Branchial Carbonic Anhydrase Induction in the Euryhaline Crab Callinectes sapidus
(2020-04-02)
Carbonic anhydrase (CA) plays an essential role as a provider of counterions for Na+/H+ and Cl-/HCO3- exchange in branchial ionic uptake processes in euryhaline crustaceans. CA activity and gene expression are low in crabs ...
Landscape-level influences of terrestrial snake occupancy within the southeastern United States
(2020-04-02)
Habitat loss and degradation are thought to be the primary drivers of species
extirpations, but for many species we have little information regarding specific habitats that
influence occupancy. Snakes are of conservation ...
