Environmental temperature is a crucial environmental factor that influences many physiological functions in fishes. Rainbow trout (Oncorhynchus mykiss) are a native anadromous species that inhabit a variety of freshwater rivers and lakes and are widel . . .

To better understand the neural mechanisms for human physiology, an invertebrate’s control on its cardiovascular system should be investigated. The leech’s heartbeat is controlled by segmental ganglia and has a phase delay in its peristaltic heartbeat . . .

Wetland ecosystems are among the most biologically productive ecosystems on Earth, yet they are being lost and degraded at an alarming rate. A growing trend to offset this loss is to construct artificial wetlands to replace the destroyed natural wetla . . .

DNA storage in the nuclei of cells is important for both compaction and the regulation of gene expression. DNA packaging is altered by chemical modifications to the tails of the histone octamer around which the DNA is wrapped, specifically histones H3 . . .

Paralemanea is a freshwater red alga genus in the family Lemaneaceae, of which Paralemanea catenata is a member. The cues by which it regulates its triphasic sexual life history are not well known, either in terms of environmental stimuli or mechanism . . .

A large portion of nitrogen deposition on southern California’s chaparral and coastal sage scrub (CSS) is due to anthropogenic sources. The implications of increasing soil nitrogen, and the relationship between soil nitrogen and carbon on soil microor . . .

In the push to determine a means to decrease the rate of biological aging in humans, conclusions about over-the-counter use of some anti-aging drugs may be premature. Rapamycin is one drug that, while currently prescribed as an immunosuppressant for v . . .

Roads are recognized as a source of increased mortality and restricted movement among populations, and are expected to impact population connectivity. However, roads that are permeable barriers would still allow some degree of gene flow, and reduced a . . .

The tropical savanna of Brazil (cerrado) is extremely species diverse and it encompasses many different physiological features. These physiological differences are influenced by rainfall and nutrient availability in the soil. Plant litter decompositio . . .

Anthropogenic nitrogen (N) deposition represents a significant input of N into coastal sage scrub (CSS) and chaparral ecosystems of Southern California. Increased N deposition has the potential to alter the decomposition rate of soil organic matter (S . . .

The importance of perennial access to water for invasive plants in arid environments was examined at eighteen sites containing Eucalyptus groves in proximity to a water source within San Diego County between June I stand September 30111, 2009. Diamete . . .

Cortaderia selloana, or pampas grass, is a serious invader of disturbed, coastal and riparian ecosystems in Southern California. The purpose of this study was to determine how the growth and physiology of C. selloana respond to various combinations of . . .

While performing, racehorses use the transverse gallop gait. When a racehorse begins to gallop, it must use either the right lead stride pattern (RLSP) or the left lead stride pattern (LLSP). When racehorses make a trot-to-gallop transition, 91% start . . .

White Spot Syndrome Virus (WSSV), a dsDNA virus, is the most important viral pathogen in cultured penaeid shrimp worldwide. In cultured shrimp, WSSV infection can reach a cumulative mortality of up to 100% within 3-10 days upon infection. Intensive sh . . .

In aquaculture facilities worldwide, T enacibaculum maritimum is a common marine pathogen that infects important marine fish species causing flexibacteriosis. Monitoring T. maritimum levels is important for effective treatment to mediate possible outb . . .

Retrotransposons encompass a specific class of mobile genetic elements that are widespread across eukaryotic genomes, the impact of which are just beginning to be deciphered. In a step towards understanding their role in litopenaied shrimp, we have he . . .

Biotelemetry studies assume that vital biological processes are unaffected by the attachment method and presence of the transmitter. I examined the effects surgically implanted transmitters (representing 0.2-0.9 % of body weight) had on feeding activi . . .

Serial analysis of gene expression (SAGE) was used to examine gene expression profiles of healthy (pathogen-free) Litopenaeus stylirostris. Of the one thousand eight hundred forty-two SAGE clones sequenced, we found seven thousand six hundred and sixt . . .

Measurements of the leaf photosynthetic light response, water potential, and specific leaf area of two tropical transitional forest tree species, Tovomita schomburgkii and Brosimum lactescens, were quantified to establish how these properties are affe . . .

The annealing algorithm in MARXAN was used to build possible marine reserves by selecting the best of 26 heterogeneous rocky intertidal sites using various modeling parameters. Because comprehensive data on biological diversity is impractical to gathe . . .
