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 ...
Life History Aspects of Exyra semicrocea (Pitcher Plant Moth) (Lepidoptera: Noctuidae)
(2022-03-03)
With as little as 3% of southeastern Coastal Plain pitcher plant bogs remaining, it is important to understand the life-history aspects of the endemic organisms that
comprise this community. In this study, we elucidate ...
Lizard embryos prioritize post-hatching energy reserves over increased hatchling body size during development
(2019-09-09)
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 ...
Long-Term Decrease in Coloration: A Consequence of Climate Change?
(2022-09-15)
Climate change has been shown to affect fitness-related traits in a wide range of taxa; for instance, warming leads to phenological advancements in many plant and animal species. The influence of climate change on social ...
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 ...
Macrophage ABCA1 reduces MyD88-dependent Toll-like receptor trafficking to lipid rafts by reduction of lipid raft cholesterol
(2022-03-11)
We previously showed that macrophages from macrophage-specifi c ATP-binding cassette transporter A1 (ABCA1) knockout (Abca1(-M/-M)) mice had an enhanced proinflammatory response to the Toll-like receptor (TLR) 4 agonist, ...
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 ...
MATERNAL TRAITS AND REPRODUCTION IN RICHARDSONS GROUND-SQUIRRELS
(2022-12-06)
Differences among conspecifics in body mass result from underlying differences in structural size and physiological condition. To determine whether the structural or physiological component of body mass has a stronger ...
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 ...
Molecular genetic evidence that dinoflagellates belonging to the genus Symbiodinium freudenthal are haploid
(2019-08-02)
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 ...
Molecular responses of brains to cross-generational warming in a coral reef fish.
(2021-12-17)
Ocean warming is a threat to marine biodiversity, as it can push marine species beyond their physiological limits. Detrimental effects can occur when marine poikilotherms are exposed to conditions beyond their optimal ...
Multiple colonizations lead to cryptic biodiversity in an island ecosystem: comparative phylogeography of anchialine shrimp species in the Ryukyu Archipelago, Japan
(2019-08-02)
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 ...
Multiple Colonizations Lead to Cryptic Biodiversity in an Island Ecosystem: Comparative Phylogeography of Anchialine Shrimp Species in the Ryukyu Archipelago, Japan
(2022-03-04)
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 ...
nadiv: an R package to create relatedness matrices for estimating non-additive genetic variances in animal models
(2019-09-15)
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 ...
Nemertean toxin genes revealed through transcriptome sequencing
(2019-04-29)
Nemerteans are one of few animal groups that have evolved the ability to utilize toxins for both defense and subduing prey, but little is known about specific nemertean toxins. In particular, no study has identified specific ...
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, ...
Osmoregulation in the Hawaiian anchialine shrimp Halocaridina rubra (Crustacea: Atyidae): expression of ion transporters, mitochondria-rich cell proliferation and hemolymph osmolality during salinity transfers
(2019-08-08)
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 ...
An Overlooked Hotspot? Rapid Biodiversity Assessment Reveals a Region of Exceptional Herpetofaunal Richness in the Southeastern United States
(2022-07-29)
We conducted a competitive bioblitz survey in four Georgia counties to raise awareness of a unique and species rich herpetofauna in the Pine Mountain/ Fall Line Sandhills Region of Georgia, and compared documented species ...
