Smalltooth sawfish are mainly found in a handful of locations in southern Florida, including the Caloosahatchee and Peace rivers. It was here that scientists have discovered that these critically endangered ocean giants are sometimes breeding without sex. The outwardly normal fish live alongside other sawfish produced through normal sexual reproduction, suggesting that these occasional virgin births may be more common in natural populations than ever suspected.

These 2 reproductive modes are both likely to be costly and, in many species, they occur at different times of the year. Small brittle stars less than 3 mm are almost always non-mature, and non-mature individuals are more likely to have recently undergone clonal division than mature brittle stars. Males appear to have a lower size threshold for sexual maturity than do females, but the sexes do not differ in the recency of clonal division.

Asexuality has major theoretical advantages over sexual reproduction, yet newly formed asexual lineages rarely endure. The success, or failure, of such lineages is affected by their mechanism of origin, because it determines their initial genetic makeup and variability. Most previously described mechanisms imply that asexual lineages are randomly frozen subsamples of a sexual population.

Please take this quick survey to tell us about what happens after you publish a paper. Coral Reefs. This paper brings together widely scattered information on sexual reproduction in scleractinian corals.

The pillar coral, Dendrogyra cylindrushas been commonly described as widely distributed, but rare throughout its geographical range in the Caribbean. Having recently been listed as Threatened under the US Endangered Species Act, an understanding of population status is needed to promote species conservation and population recovery. Previous to this study the status of the pillar coral population in the state waters of Florida, U. A, was relatively unknown primarily due to few colonies being recorded and no comprehensive summary of population abundance, distribution or health being completed.
