Flexible feeding kinematics of a tropical carnivorous anuran tadpole
(Wiley, 2014-07-01)Leptodactylus labyrinthicus tadpoles are known predators of anuran eggs and hatchlings, but they are also able to filter-feed in the water column and scrape food off of firm substrates. We evaluated and compared these ... -
Flexible, Front-Facing Luminescent Solar Concentrators Fabricated from Lumogen F Red 305 and Polydimethylsiloxane
(Hindawi, 2019-04-30)Luminescent solar concentrators (LSCs) fabricated with transparent host materials and fluorescent organic dyes are cost effective and versatile tools for solar power production. In this study, the first flexible, front-facing ... -
Fluctuation in a Rocky Mountain population of salamanders: Anthropogenic acidification of natural variation?
(Society for the Study of Amphibians and Reptiles, 1992)We monitored the demographics of the salamander Ambystoma tigrinum nebulosum as part of a community-wide study on the effects of acidification in sub-alpine (elevation 3600 m) ponds in central Colorado. A decline in A. ... -
Flux Synthesis, Optical and Photocatalytic Properties of n-type Sn2TiO4: Hydrogen and Oxygen Evolution under Visible Light
(American Chemical Society, 2016-12-27)The n-type Sn2TiO4 phase was synthesized using flux methods and found to have one of the smallest visible-light bandgap sizes known that also maintains suitable conduction and valence band energies for driving photocatalytic ... -
Foraging tactics in alternative heterochronic salamander morphs: trophic quality of ponds matters more than water permanency.
(Wiley-Blackwell, 2007-09)1. In lentic freshwater habitats, the composition of animal assemblages shifts along a gradient from temporary to permanent basins. When habitats with different degrees of permanence are at the scale of the home range of ... -
Foraging trade-offs along a predator-permanence gradient in subalpine wetlands
(Ecological Society of America, 1999-09)We conducted a series of field and laboratory experiments to determine the direct and indirect effects of a top predator, the tiger salamander (Ambystoma tigrinum nebulosum), on larvae of two species of limnephilid caddisflies ... -
Forensic informativity of ~3,000 bp of coding sequence of domestic dog mtDNA.
(Wiley Online Library, 2014-07)The discriminatory power of the noncoding control region (CR) of domestic dog mitochondrial DNA alone is relatively low. The extent to which the discriminatory power could be increased by analyzing additional highly variable ... -
Forested watersheds mitigate the thermal degradation of headwater fish assemblages under future climate change
(Wiley, 2022-07)Certain habitat features of stream ecosystems can reduce their sensitivity to climate change and help protect the integrity of cold-water aquatic resources. Identifying such features is imperative for conserving the climate ... -
Forgiveness in Vertical Relationships: Incentive and Termination Effects
(Informs, 2014-11-01)Two types of contractual solutions have been proposed for resolving incentive conflicts in vertical relationships: formal and relational (i.e., enforceable or not by third parties). Much is known about the optimal structure ... -

Formation of black hole x-ray binaries in globular clusters
(Institute of Physics, 2010-07-10)Inspired by the recent identification in extragalactic globular clusters of the first candidate black hole–white dwarf (BH–WD) X-ray binaries, where the compact accretors may be stellar-mass black holes (BHs), we explore ... -
Formation of Low-mass Black Holes and Single Millisecond Pulsars in Globular Clusters
(IOP Publishing Ltd, 2022-07-01)Close encounters between neutron stars and main-sequence stars occur in globular clusters and may lead to various outcomes. Here we study encounters resulting in the tidal disruption of the star. Using N-body models, we ... -
Freshwater unionid mussels threatened by predation of Round Goby (Neogobius melanostomus)
(Nature, 2022-07-27)Indigenous freshwater mussels (Unionidae) are integral to riverine ecosystems, playing a pivotal role in aquatic food webs and providing ecological services. With populations on the decline worldwide, freshwater mussels ...
