Here we document introns in two Symbiodinium clades that were most likely gained following divergence of this genus
from other peridinin-containing dinoflagellate lineages. Soluble peridinin-chlorophyll a-proteins (sPCP) occur in short and
long...

Because iso- and anisohydric species differ in stomatal regulation
of the rate and magnitude of fluctuations in shoot
water potential, they may be expected to show differences in
the plasticity of their shoot water relations components, but...

OBJECTIVE: The associations of some risk factors with cardiovascular disease (CVD) are attenuated in
older age; whereas others appear robust. The present study aimed to compare CVD risk factors across
older age. METHODS: Participants (n = 4883) in...

The effect of the Coriolis interaction upon the sharing of energy between rotational and vibrational excitation
during an electronic transition is considered with particular emphasis on recoil-induced excitation during
photoionization. If there is...

Recent reform initiatives in undergraduate biology call for curricula that prepare
students for dealing with real-world issues and making important links between
science and society. In response to this call, we have developed an issues-based...

Large-scale poisoning events are common to scavenging bird species that forage communally,
many of which are in decline. To reduce the threat of poisoning and compensate for other persistent threats,
management, including supplemental feeding, is...

Condors and vultures comprise the only group of terrestrial vertebrates in the world that are
obligate scavengers, and these species move widely to locate ephemeral, unpredictable, and patchily-distributed
food resources. In this study, we used...

Chordomas are uncommon neoplasms arising from notochord remnants, most commonly
occurring in the axial skeleton. Extraskeletal soft tissue chordomas are rare primary tumors, and
primary intestinal chordomas have not been reported. Herein we report...

Developmental bisphenol A (BPA) exposure is associated with adverse behavioral
effects, although underlying modes of action remain unclear. Because BPA is a
suspected xenoestrogen, the objective was to identify sex-based changes in adult
zebrafish...

Analytical methods capable of trace measurement of semi-volatile organic
compounds (SOCs) are necessary to assess the exposure of tadpoles to contaminants as a
result of long-range and regional atmospheric transport and deposition. The following...
