Development of endocytosis, degradative activity, and antigen processing capacity during GM-CSF driven differentiation of murine bone marrow
(2022-03-11)
Dendritic cells (DC) are sentinels of the immune system, alerting and enlisting T cells to clear pathogenic threats. As such, numerous studies have demonstrated their effective uptake and proteolytic activities coupled ...
Developmental reaction norms vary among families of lizards in response to multivariate nest environments
(2024-08-23)
Developmental plasticity is the capacity of a single genotype to express multiple phenotypes in response to different early-life environments. Such responses are defined by reaction norms, which may vary among individuals ...
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 ...
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 ...
Discovery and Broad Relevance May Be Insignificant Components of Course-Based Undergraduate Research Experiences [CUREs] for Non-Biology Majors
(2022-03-11)
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 Auchincloss et al. ...
Discovery and evolution of novel hemerythrin genes in annelid worms
(2019-04-29)
BACKGROUND: Despite extensive study on hemoglobins and hemocyanins, little is known about hemerythrin (Hr) evolutionary history. Four subgroups of Hrs have been documented, including: circulating Hr (cHr), myohemerythrin ...
Do Small Classes in Higher Education Reduce Performance Gaps in STEM?
(2019-07-11)
Performance gaps in science are well documented, and an examination of underlying mechanisms that lead to underperformance and attrition of women and underrepresented minorities (URM) may offer highly targeted means to ...
Does season-dependent reproductive value of offspring drive the evolution of life-history traits in Anolis lizards?
(2019-09-15)
An important component of the reproductive strategy of many animals involves a seasonal shift in reproductive traits (i.e., clutch size, egg quality). Such shifts typically occur because environmental factors that influence ...
Embryo development and global change: how do reptile embryos respond to ecologically relevant thermal stress?
(2019-09-15)
Two components of global change, climate change and urbanization, both contribute to increased ambient temperatures that may induce heat stress or mortality in animals. Each phenomenon independently results in both increased ...
Embryo development and global change: how do reptile embryos respond to ecologically relevant thermal stress?
(2019-09-15)
Two components of global change, climate change and urbanization, contribute to increased ambient temperatures that cause heat stress or mortality in animals. Many animals can respond to harmful temperatures behaviorally; ...
Embryological development and global change: how do reptile embryos respond to thermal stress in urban environments?
(2019-09-15)
Two components of global change, climate change and urbanization, both contribute to increased ambient temperatures that may induce heat stress or mortality in animals. Each phenomenon independently results in both increased ...
Enhancing Diversity in Undergraduate Science: Self-Efficacy Drives Performance Gains with Active Learning
(2019-08-07)
Efforts to retain underrepresented minority (URM) students in science, technology, engineering, and mathematics (STEM) have shown only limited success in higher education, due in part to a persistent achievement gap between ...
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 ...
The evolution of signal design in manakin plumage ornaments
(2022-07-29)
Animal signals are characterized by two design components: efficacy (detectability) and content (message being conveyed). Selection for efficient signal perception should favor the evolution of traits that exhibit an optimal ...
Expansion of the Range of the Introduced Greenhouse Frog, Eleutherodactylus planirostris, in Coastal Alabama
(2022-09-16)
Eleutherodactylus planirostris (Greenhouse Frog), originally from Cuba, the Bahamas, and the Florida Keys, has been introduced to mainland Florida and has spread across the southeastern US. We used automated recording ...
Fishes of the Streams of Acadia National Park, Maine
(2021-05-05)
Acadia National Park (ANP) is a non-continuous conglomerate of park lands interspersed with private lands, which is located mainly on Mount Desert Island, ME. Surveys of fishes in ANP have largely ignored or under-sampled ...
Fitness implications of seasonal climate variation in Columbian ground squirrels
(2020-04-01)
The influence of climate change on the fitness of wild populations is often studied in the context of the spring onset of the reproductive season. This focus is relevant for climate influences on reproductive success, but ...
Fluctuating environments hinder the ability of female lizards to choose suitable nest sites for their embryos
(2022-11-07)
Nesting behavior is an important part of reproduction that affects maternal fitness. Females of most oviparous species choose microhabitats for nesting that have positive effects on embryo development. However, choosing ...
Frequency of Occurrence and Population-Dynamic Consequences of Different Forms of Density-Dependent Emigration
(2022-08-02)
Emigration is a fundamental process affecting species' local, regional, and large-scale dynamics. The paradigmatic view in ecology is that emigration is density independent (DIE) or positive density dependent (1DDE). ...
