ABSTRACT Samples were extracted in Erlenmeyer flasks with hexane‐ethanol‐acetone (50:25:25). After extraction, 15 mL of water added to separate the solution into polar and nonpolar layers. Lycopene was concentrated upper phase while other components pigments contained lower phase. The lycopene analyzed using isocratic HPLC a C‐18 column methanol‐THF‐water (67:27:6) mobile (β‐caro‐tene eluted as chromatographically pure peaks.
Coastal economies are often supported by activities that rely on commercial or recreational vessels to move people goods, such as shipping, transportation, cruising, and fishing. Unintentionally, frequent intense vessel traffic can contribute erosion of coastlines; this be particularly evident in sheltered systems where shoreline should minimal the absence boat waves. We reviewed state science known effects waves stability, examined data erosion, turbidity, armoring patterns for evidence a...
Stock enhancement of severely exploited, recruitment-limited fisheries has been controversial for several reasons, one which is the lack information about competency, competitiveness, and survivorship hatchery-reared individuals released into field. Because efforts have focused on finfish, even less available with to assess potential crustaceans. The Chesapeake Bay stock blue crabs Callinectes sapidus declined by more than 80% over past 12 years exhibited recruitment limitation, leading...

Intertidal organisms are influenced by the tidal, daily, and seasonal environmental variability of their habitat. Interannual variability, although often less severe than shorter‐scale may also be important in structuring intertidal systems. This study compares magnitude changes a rocky fish guild occurring on scale with those during an El Niño Southern Oscillation (ENSO). I examined tidepool assemblage structure habitat use two southern California sites approximately every 3 months from...
In certain cases of severely depleted fishery stocks, combining stock enhancement with traditional management techniques may be a useful way returning stocks to an exploitable size. The Chesapeake Bay blue crabs (Callinectes sapidus) has declined over the past decade and appears recruitment-limited, making it appropriate candidate for efforts. This study serves as first step in determining whether large-scale crab is feasible. Four hatchery-raised cohorts 4000 10 000 (25 total) juvenile...
Numerous taxa have the ability to autotomize parts of their bodies increase survivorship in dangerous or stressful situations. Effects autotomy on a surviving individual's subsequent ecological function is not well understood for most species. In this study, we provide first quantification patterns within population (frequency injured individuals) and an individual missing pereopods, limbs) Asian shore crab Hemigrapsus sanguineus. This crab, member family Grapsidae, recent introduction...

I examined the effects of low-tide timing on tidepool use by two southern California fishes, Clinocottus analis and Girella nigricans. Abundance these fishes in middle upper intertidal pools was higher when low tides occurred at night or early morning (4.4–9.7 fish per pool) than afternoon (1.3–3.4 pool). Mean size also during nighttime daytime tides. Tidepools zone generally displayed greater differences abundance between lower pools. In addition, tidepools reached temperatures (up to 30 C)...
ABSTRACT Reconstituted single strength orange juice was distilled to recover diacetyl. 0.5 mL of 1N LiOH added 4.5 distillate. Using a static mercury drop electrode, current vs potential scan performed between −0.7 and −1.10 an Ag/AgCl reference electrode. The reduction for diacetyl −0.83 V. Peak heights were proportional concentration throughout the test range (8.3 ppb 1 ppm). Diacetyl recoveries approximately 85%.
