High-Throughput Sequencing Characterizes Intertidal Meiofaunal Communities in Northern Gulf of Mexico (Dauphin Island and Mobile Bay, Alabama)
Abstract. Meiofauna are important components of food webs and for nutrient exchange between the benthos and water column. Recent studies have focused on these communities in the Gulf of Mexico due to potential impacts of ... -
Data for: Adaptive seasonal shift towards investment in fewer, larger offspring: Evidence from field and laboratory studies
1. Seasonal changes in reproduction have been described for many taxa. As reproductive seasons progress, females often shift from greater energetic investment in many small offspring towards investing less total energy ... -
nadiv: an R package to create relatedness matrices for estimating non-additive genetic variances in animal models
1. The Non-Additive InVerses (nadiv) R software package contains functions to create and use non-additive genetic relationship matrices in the animal model of quantitative genetics. 2. This study discusses the concepts ... -
Thermal Spikes Caused by the Urban Heat Island Effect Result in Differential Egg Survival of a Non-native Lizard (Anolis cristatellus)
Embryonic development in ectotherms is very sensitive to abiotic nest conditions. In reptiles, high incubation temperatures often result in relatively short incubation periods and large hatching size, but extremely high ... -
Thermal Spikes Caused by the Urban Heat Island Effect Result in Differential Egg Survival of a Non-native Lizard (Anolis cristatellus)
Embryonic development in ectotherms is very sensitive to abiotic nest conditions. In reptiles, high incubation temperatures often result in relatively short incubation periods and large hatching size, but extremely high ... -
Does season-dependent reproductive value of offspring drive the evolution of life-history traits in Anolis lizards?
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 ... -
Embryological development and global change: how do reptile embryos respond to thermal stress in urban environments?
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?
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?
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; ... -
Constantly fluctuating in an inconsistent way: comparing the effects of sinusoidal and naturally fluctuating incubation temperatures on embryo development
Temperature is a commonly studied environmental factor influencing embryo development in oviparous ectotherms. Though most studies use constant temperature incubation conditions, researchers are aware of the effects of ... -
Even when yolk supplies are experimentally reduced, lizard embryos maintain yolk reserves through to hatching
Embryonic development in oviparous organisms is fueled by maternally-allocated yolk, with many organisms hatching before that energy store is completely used up; the resultant leftover (residual) yolk is internalized and ... -
Data for: Thermal tolerance in the urban heat island: Thermal sensitivity varies ontogenetically and differs between embryos of two sympatric ectotherms
Most studies of thermal tolerance use adults, but early-life stages (e.g. embryos) are often more sensitive to thermal agitation. Studies that examine effects on embryos rarely assess the potential for thermal tolerance ... -
The players in a mutualistic symbiosis: insects, bacteria, viruses, and virulence genes
Aphids maintain mutualistic symbioses involving consortia of coinherited organisms. All possess a primary endosymbiont, Buchnera, which compensates for dietary deficiencies; many also contain secondary symbionts, such as ... -
Osmoregulation in the Hawaiian anchialine shrimp Halocaridina rubra (Crustacea: Atyidae): expression of ion transporters, mitochondria-rich cell proliferation and hemolymph osmolality during salinity transfers
Studies of euryhaline crustaceans have identified conserved osmoregulatory adaptions allowing hyper-osmoregulation in dilute waters. However, previous studies have mainly examined decapod brachyurans with marine ancestries ... -
Enhancing Diversity in Undergraduate Science: Self-Efficacy Drives Performance Gains with Active Learning
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 ... -
Physiological consequences of an altered flow regime on Alabama bass (Micropterus henshalli)
There are numerous studies on the effects of dams on aquatic biota, yet relatively little is known about whether hydropeaking activities cause physiological change in fish. Using Alabama bass (Micropterus henshalli) as a ... -
The Adaptive Bleaching Hypothesis: Experimental Tests of Critical Assumptions
Coral bleaching, the loss of color due to loss of symbiotic zooxanthellae or their pigment, appears to be increasing in intensity and geographic extent, perhaps related to increasing sea surface temperatures. The adaptive ... -
Molecular genetic evidence that dinoflagellates belonging to the genus Symbiodinium freudenthal are haploid
Microscopic and cytological evidence suggest that many dinoflagellates possess a haploid nuclear phase. However, the ploidy of a number of dinoflagellates remains unknown, and molecular genetic support for haploidy in this ... -
Multiple colonizations lead to cryptic biodiversity in an island ecosystem: comparative phylogeography of anchialine shrimp species in the Ryukyu Archipelago, Japan
Archipelagos of the Indo-West Pacific are considered to be among the richest in the world in biodiversity, and phylogeographic studies generally support either the center of origin or the center of accumulation hypothesis ...
