Reproduction and development in Halocaridina rubra Holthuis, 1963 (Crustacea: Atyidae) clarifies larval ecology in the Hawaiian anchialine ecosystem
(2019-08-01)
Larvae in aquatic habitats often develop in environments different from those they inhabit as adults. Shrimp in the Atyidae exemplify this trend, as larvae of many species require salt or brackish water for development, ...
Reproductive Value and the Stochastic Demography of Age-Structured Populations
(2022-09-15)
The dynamics of an age-structured population in a fluctuating environment is determined by the stochastic individual contributions from annual survival and fecundity to the total reproductive value of the population the ...
Reproductive Value and the Stochastic Demography of Age-Structured Populations
(2020-06-03)
The dynamics of an age-structured population in a fluctuating environment is determined by the stochastic individual contributions from annual survival and fecundity to the total reproductive value of the population the ...
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 ...
Reversal of magnetic field rotation in the reconnection layer due to shear flow effects
(2022-09-29)
We investigate the effects of shear flows on the so-called component reconnection, in which the guide field B-y not equal 0, by solving a one-dimensional Riemann problem for magnetopause reconnection using a resistive MHD ...

Ring/Shell Ion Distributions at Geosynchronous Orbit
(2020-05-28)
One year's worth of plasma observations from geosynchronous orbit is examined for ion distributions that may simultaneously be subject to the ion Bernstein (IB) instability (generating fast magnetosonic waves) and the ...

Scalings for the Alfven-cyclotron instability: Linear dispersion theory and hybrid particle-in-cell simulations
(2020-06-01)
The Alfven-cyclotron instability is driven by an ion temperature anisotropy such that T-perpendicular to/T-|| >1 where and || denote directions perpendicular and parallel to a uniform background magnetic field B-o, ...
Scalings for the Alfven-cyclotron instability: Linear dispersion theory and hybrid particle-in-cell simulations
(2022-10-27)
The Alfven-cyclotron instability is driven by an ion temperature anisotropy such that T-perpendicular to/T-|| >1 where and || denote directions perpendicular and parallel to a uniform background magnetic field B-o, ...
Scalings of Alfven-cyclotron and ion Bernstein instabilities on temperature anisotropy of a ring-like velocity distribution in the inner magnetosphere
(2022-09-29)
A ring-like proton velocity distribution with f(p)(v)/v>0 and which is sufficiently anisotropic can excite two distinct types of growing modes in the inner magnetosphere: ion Bernstein instabilities with multiple ion ...

Seasonal Shifts in Reproduction Depend on Prey Availability for an Income Breeder
(2022-03-04)
The evolution of reproductive strategies depends on local environmental conditions. When environments are seasonal, selection favors individuals that align changes in key reproductive traits with seasonal shifts in habitat ...
Second-order, two-electron Dyson propagator theory: Comparisons for vertical double ionization potentials
(2021-01-26)
The second-order, two-electron Dyson propagator is derived using superoperator theory with a
spin-adapted formulation. To include certain ladder diagrams to all orders, the shifted-denominator
SD2 approximation is made. ...
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 ...
Semiautomated Identification and Characterization of Dunes at Hargraves Crater, Mars
(2022-09-29)
The Mars Global Digital Dune Database (MGD(3)) contains information on Martian dune fields and prepared manually from the Thermal Emission Imaging System (THEMIS; 100 m/pixel) images. Although the MGD(3)outlines dune fields, ...
Sequential addition of H2O, CH3OH, and NH3 to Al3O3-: A theoretical study
(2021-01-26)
Photoelectron spectra of two species, Al3O3(H2O)(2)(-) and Al3O3(CH3OH)(2)(-), that are produced by the addition of two water or methanol molecules to Al3O3- are interpreted with density-functional geometry optimizations ...
Severe mammal declines coincide with proliferation of invasive Burmese pythons in Everglades National Park
(2022-09-15)
Invasive species represent a significant threat to global biodiversity and a substantial economic burden. Burmese pythons, giant constricting snakes native to Asia, now are found throughout much of southern Florida, including ...

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 ...
