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 . . .
