Effects of spatial distribution and reproductive biology on in situ fertilization rates of a broadcast-spawning invertebrate.

In situ fertilization was examined in the gorgonian Pseudoplexaura porosa during 1994 and 1995 spawning events in the San Bias Islands, Panama, to assess spatial and temporal variation in fertilization success and to determine whether in situ fertilization was sperm limited. Fertilization rates did not differ significantly between years (60% vs. 55%), but monthly means were significantly different, ranging from 22% to 66%. Fertilization rate varied among days, ranging from 0 to 85%; 80% of th...

In situ rates of fertilization among broadcast spawning gorgonian corals.
The Biological Bulletin ; Introduction One of the primary goals of benthic ecology has been the determination of the factors limiting populations. For most of this century, such efforts have been concentrated on post-recruitment events in the life history of the organism (i.e., Connell, 1961, and hundreds of subsequent
Importance of spatial population characteristics on the fertilization rates of sea urchins.
The Biological Bulletin ; Introduction Fertilization success of sea urchins and other free-spawning benthic invertebrates has been the focus of many empirical and theoretical studies over the last 25 years. In particular, a seminal paper by Denny and Shibata (1989) provided a mathematical framework for predicting
Conflicting morphological and reproductive species boundaries in the coral genus Platygyra.
The Biological Bulletin ; Introduction Species boundaries in scleractinian corals are primarily based on skeletal morphology (e.g., Ellis and Solander, 1786; Vaughan and Wells, 1943; Veron et al., 1977; but see Lang, 1984). It is generally assumed that morphological differences between coral species are highly correlated
Synthetic estrogen hampers trout fertility. (Spawning Trouble).
Science News ; When women take birth control pills, some of the hormones in the pills ends up in sewage effluent and waterways where it may be harming trout populations. Researchers now say that even short-term, low-level exposures to one such hormone, ethynylestradiol (EE2), can reduce a male trout's fertility
NEW REPRODUCTIVE TECHNOLOGY.
Alberta Report ; * The Canadian Fertility and Andrology Society (www.upmc.edu/isa/canada) released national data on in vitro fertilization rates. According to the society, last year 26% of 4,290 artificial reproduction procedures done at 17 of 20 Canadian infertility clinics resulted in pregnancies. The percentage
Oocyte cryopreservation now feasible, expert says: especially oncology patients.(News)
OB GYN News ; SAN ANTONIO -- Oocyte cryopreservation, once considered highly experimental, should now be presented as a viable option to women--especially oncology patients, according to one of the leading experts in this procedure. Now this technique is feasible, said Dr. Eleonora Porcu of the department of
Effects of Nitrogen Fertilization on Phosphorus Uptake in Bermudagrass Forage Grown on High Soil-Test Phosphorus Sites
Professional Animal Scientist ; Abstract Common bermudagrass [Cynodon dactylon (L.) Pers.] was harvested from two producer sites (Latta and Stephens) with high soil-test P (286 and 153 ppm, respectively) to assess the effects of N fertilization on P uptake and potential removal in hay or silage. Ammonium nitrate was applied in
Ornithology: Songbirds' Fertile Stray Notes
The Washington Post ; It is no secret that many monogamous songbirds are enthusiastically adulterous, and sexual liaisons outside the home nest often produce much higher fertilization rates than couplings between mates. T.R. Birkhead and colleagues from Sheffield University in England went looking for the reason that
The effect of sperm competition on male gain curves in a colonial marine invertebrate.
Ecology ; INTRODUCTION Hermaphroditic plants and animals can potentially maximize reproductive success through a wide variety of different strategies. Since reproduction occurs via both genders, the total reproductive success of an individual must be evaluated as the sum of the reproductive success obtained
CASE STUDY: In Situ Ruminal Nitrogen and Neutral-Detergent Insoluble Nitrogen Disappearance from Bermudagrass Fertilized with Different Nitrogen Rates and Harvested on Two Dates
Professional Animal Scientist ; ABSTRACT Fertilizing bermudagrass (Cynodon dactylon L. Pers.) with N can produce large quantities of forage and increase plant N concentrations. Bermudagrass growing on a caged-layer manure-amended site was fertilized with ammonium nitrate at 4 rates (0, 56, 112, and 168 kg N/ha) approximately 1 mo
