Data for: Estimating the Landscape of Natural Selection During Island Colonization in an Invasive Lizard
(2024-05-21)
Colonization of new habitats exposes populations to novel selective pressures, and the evolutionary dynamics of invasive species are determined by how the founding environment interacts with the phenotypes of invaders. ...
Genetic variation underlies plastic responses to global change drivers in the purple sea urchin, Strongylocentrotus purpuratus
(2024-05-17)
Phenotypic plasticity and adaptive evolution enable population persistence in response to global change. However, there are few experiments that test how these processes interact within and across generations, especially ...
Anemonefish oxygenate their anemone hosts at night
(2023-09-20)
Many stony coral-dwelling fishes exhibit adaptations to deal with hypoxia among the branches of their hosts; however, no
information exists on the respiratory ecophysiology of obligate fish associates of non-coral organisms ...
Net superoxide levels: steeper increase with activity in cooler female and hotter male lizards
(2023-09-20)
Ectotherms increase their body temperature in response to ambient heat, thereby elevating their metabolic rate. An often inferred consequence of this is an overall upregulation of gene expression and energetic expenditure, ...
Can mixed assessment methods make biology classes more equitable
(2023-09-20)
Many factors have been proposed to explain the attrition of women in science, technology, engineering and math fields, among them the lower performance of women in introductory courses resulting from deficits in incoming ...
Magnitude and Predictability of pH Fluctuations Shape Plastic Responses to Ocean Acidification
(2023-06-17)
Phenotypic plasticity is expected to facilitate the persistence of natural populations as global change progresses. The attributes of fluctuating environments that favor the evolution of plasticity have received extensive ...
Reptile Embryos Lack the Opportunity to Thermoregulate by Moving within the Egg
(2023-05-17)
Historically, egg-bound reptile embryos were thought to passively thermoconform to the nest environment. However, recent observations of thermal taxis by embryos of multiple reptile species have led to the widely discussed ...
Why are incubation periods longer in the tropics? A common-garden experiment with house wrens reveals it is all in the egg
(2023-05-17)
Incubation periods of Neotropical birds are often longer than those of related species at temperate latitudes. We conducted a common-garden experiment to test the hypothesis that longer tropical incubation periods result ...
Plumage color as a composite trait: Developmental and functional integration of sexual ornamentation
(2023-05-17)
Most studies of condition-dependent sexual ornaments have treated such ornaments as single traits. However, sexual ornaments are often composites of several components, each produced by partially independent developmental ...
Bacteria as an agent for change in structural plumage color: Correlational and experimental evidence
(2023-05-17)
Recent studies have documented that a diverse assemblage of bacteria is present on the feathers of wild birds and that uropygial oil affects these bacteria in diverse ways. These findings suggest that birds may regulate ...
Selective predation on Utah prairie dogs
(2023-05-17)
Predation always affects demography and population dynamics, but removal of certain types of individuals is especially consequential. Predators strike quickly and commonly avoid areas with human observers, however, and ...
The relative importance of life-history variables to population growth rate in mammals: Cole's prediction revisited
(2023-05-17)
The relative importance of life-history variables to population growth rate (lambda) has substantial consequences for the study of life-history evolution and for the dynamics of biological populations. Using life-history ...
Micro- and Macroevolutionary Trade-Offs in Plant-Feeding Insects
(2023-05-17)
A long-standing hypothesis asserts that plant-feeding insects specialize on particular host plants because of negative interactions (trade-offs) between adaptations to alternative hosts, yet empirical evidence for such ...
Data from: Dynamics of honey bee colony death and its implications for Varroa destructor mite transmission using observation hives
(2023-01-14)
This dataset contains the data which were collected for the "dynamics of death" research project. There are four data files attached: one readme file, and three sets of data.
