High activity before breeding improves reproductive performance by enhancing mitochondrial function and biogenesis
(2022-03-13)
Understanding of physiological responses of organisms is typically based on data collected during an isolated event. Although many fundamental insights have been gained from these studies, evaluating the response to a ...
Sex-Specific Effects of Incubation Temperature on Embryonic Development of Zebra Finch (Taeniopygia guttata) Embryos
(2022-03-04)
In oviparous species, the embryonic environmentparticularly temperaturecan alter phenotype and survival of an individual by affecting its size as well as its metabolic rate. Previous studies have shown that incubation ...
Thermal spikes from the urban heat island increase mortality and alter physiology of lizard embryos
(2022-03-13)
Effects of global change (i.e. urbanization, climate change) on adult organisms are readily used to predict the persistence of populations. However, effects on embryo survival and patterns of development are less studied, ...
Biomechanical factors influencing successful self-righting in the pleurodire turtle Emydura subglobosa
(2022-07-29)
Self-righting performance is a key ability for most terrestrial animals, and has been used as a metric of fitness, exhaustion and thermal limits in a variety of taxa. However, there is little understanding of the underlying ...
An in vivo test of the biologically relevant roles of carotenoids as antioxidants in animals
(2022-03-13)
Carotenoids are well known for their contribution to the vibrant coloration of many animals and have been hypothesized to be important antioxidants. Surprisingly few examples of carotenoids acting as biologically relevant ...
Solitary potential structures associated with ion and electron beams near 1 R-E altitude
(2020-06-30)
Small-scale solitary electric potential structures are commonly observed on auroral field lines with the Polar Electric Field Instrument (EFI). This study focuses on observations of solitary structures in the southern ...
Delocalized water and fluoride contributions to Dyson orbitals for electron detachment from the hydrated fluoride anion
(2021-01-26)
The experimental vertical electron detachment energy VEDE of aqueous fluoride, F− H2O , is
approximately 9.8 eV, but spectral assignment is complicated by interference between F− 2p and
H2O 1b1 orbitals. The electronic ...
Electron propagator and coupled-cluster calculations on the photoelectron spectra of thiouracil and dithiouracil anions
(2021-01-26)
Electron affinities, vertical electron detachment energies, and isomerization energies of 4-thiouracil, 2-thiouracil, and 2,4-dithiouracil and their valence anions have been calculated with ab initio electron propagator ...
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 ...
Variation of Morphology and Elemental Concentrations in the California Nickel Hyperaccumulator Streptanthus polygaloides (Brassicaceae)
(2021-01-04)
The Ni hyperaccumulator Strepthanthus polygaloides (Brassicaceae)
is one of a handful of Ni hyperaccumulators known from continental North
America. Surveys have revealed four distinctive morphs of this species, relying ...
Do Tropical Nickel Hyperaccumulators Mobilize Metals into Epiphytes? A Test Using Bryophytes from New Caledonia
(2021-01-04)
Hyperaccumulator plants mobilize large amounts of certain elements
from the soil into their tissues. Those elements then may be transferred to other organisms in those communities. Using a humid tropical forest site in ...
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 ...
The interaction-induced dipole of H-2-H: New ab initio results and spherical tensor analysis
(2020-04-08)
We present numerical results for the dipole induced by interactions between a hydrogen molecule and a hydrogen atom, obtained from finite-field calculations in an aug-cc-pV5Z basis at the unrestricted coupled-cluster level ...
Multi-approach synergic investigation between land surface temperature and land-use land-cover
(2020-03-17)
Rapid urban expansion and associated land-use land-cover (LULC) change in India have emerged as a
serious environmental threat that accelerates the impacts of urban heat island intensity (UHII). Three
independent ...
Hard and Soft Anatomy in Two Genera of Dondersiidae (Mollusca, Aplacophora, Solenogastres)
(2020-02-26)
Phylogenetic relationships and identifications
in the aplacophoran taxon Solenogastres (Neomeniomorpha)
are in flux largely because descriptions of hard parts––
sclerites, radulae, copulatory spicules––and body shape
have ...
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 ...
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 ...
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 ...
Cluster perturbation theory. V. Theoretical foundation for cluster linear target states
(2020-05-20)
Cluster perturbation (CP) theory was developed in Paper I [F. Pawlowski et al., J. Chem. Phys. 150, 134108 (2019)] for a coupled cluster (CC) target state and is extended in this paper to comprehend a cluster linear (CL) ...
