Instability of development and fractal architecture in dryland plants as an index of grazing pressure Instability of development and fractal architecture in dryland plants as an index of grazing pressure
Developmental instability has been used to monitor the well-being of natural populations exposed to physical, chemical and biological stressors. Here, we use developmental instability to assess the impact of grazing on Chrysothamnus greenii and Seriphidium novumshrubs, and Oryzopsis hymenoidesgrass, common in the arid intermountain west of the U.S.A. Statistical noise in allometric...

The status of Moapa coriacea and Gila seminuda and status information on other fishes of the Muddy River, Clark County, Nevada The status of Moapa coriacea and Gila seminuda and status information on other fishes of the Muddy River, Clark County, Nevada
Moapa coriacea is endemic to the headwaters (Warm Springs area) of the Muddy River, Clark County, Nevada. The Warm Springs area was snorkeled and Moapa coriacea and Gila seminuda enumerated in August 1994 after a fire, and in May 1997 after a diversion dam had been removed from the downstream end. Gila seminuda had been reported in greatest abundance downstream from the Warm Springs area...

Correlation between plasma component levels of cultured fish and resistance to bacterial infection Correlation between plasma component levels of cultured fish and resistance to bacterial infection
Mortalities of yellowtail Seriola quinqueradiata artificially infected with Lactococcus garvieae and of rainbow trout Oncorhynchus mykiss artificially infected with Vibrio anguillarum were compared with the levels of plasma components measured prior to challenge. The levels of plasma total cholesterol, free cholesterol and phospholipid of fish surviving infection were significantly...

How organisms do the right thing: The attractor hypothesis How organisms do the right thing: The attractor hypothesis
Neo-Darwinian theory is highly successful at explaining the emergence of adaptive traits over successive generations. However, there are reasons to doubt its efficacy in explaining the observed, impressively detailed adaptive responses of organisms to day-to-day changes in their surroundings. Also, the theory lacks a clear mechanism to account for both plasticity and canalization. In...

Vertical distribution of the chloromonad flagellate Heterosigma carterae in columns: Implications for bloom development Vertical distribution of the chloromonad flagellate Heterosigma carterae in columns: Implications for bloom development
Blooms of the marine flagellate Heterosigma carterae have been associated with catastrophic fish kills at mariculture facilities around the world. The precise cause(s) of the sudden appearance and disappearance of Heterosigma surface blooms has not been completely described or understood. Environmental data from prior studies of blooms indicate the presence of vertical stratification of...

Thermally induced chronic developmental stress in coho salmon: Integrating measures of mortality, early growth and fluctuating asymmetry Thermally induced chronic developmental stress in coho salmon: Integrating measures of mortality, early growth and fluctuating asymmetry
Developmental stability, or homeostasis, facilitates the production of consistent phenotypes by buffering against stress. Fluctuating asymmetry is produced by developmental instability and is manifested as small random departures from bilateral symmetry. Increased fluctuating asymmetry is thought to parallel compromised fitness, in part, because stress promotes energy dissipation...

A ribonuclease protection assay can distinguish spring viremia of carp virus from pike fry rhabdovirus A ribonuclease protection assay can distinguish spring viremia of carp virus from pike fry rhabdovirus
Thirteen rhabdovirus isolates from 10 teleost fish species as well as reference strains of spring viraemia of carp virus (SVCV) and pike fry rhabdovirus (PFRV) cross-reacted in an indirect immunofluorescence assay and were thus indistinguishable by this method. A ribonuclease protection assay (RPA) using a super(32)P-labeled RNA probe made from a cloned copy of the full length SVCV...

Diel and distributional abundance patterns of fish embryos and larvae in the lower Columbia and Deschutes rivers Diel and distributional abundance patterns of fish embryos and larvae in the lower Columbia and Deschutes rivers
Diel and distributional abundance patterns of free embryos and larvae of fishes in the lower Columbia River Basin were investigated. Ichthyoplankton samples were collected in 1993 during day and night in the main-channel and a backwater of the lower Columbia River, and in a tributary, the Deschutes River. Fish embryos and larvae collected in the main-channel Columbia River were primarily...
