- Entrainment of larval release in an intertidal crab ( Uca thayeri) after exposure to a different tidal regime: Testing the "plasticity" hypothesis.
- Creator
- Weaver, Ann, Florida Atlantic University, Salmon, Michael
- Abstract/Description
-
Endogenous rhythms allow most organisms to synchronize their behavior and physiology with physical cycles that vary on a daily, lunar or annual cycle. Populations within species often show variation in the timing of functionally identical rhythms. This variation occurs because physical cycles may differ with geography. The purpose of this study was to determine whether hatching rhythms shown by fiddler crabs (Genus Uca) on one coastline could be entrained by the different tide patterns...
Show moreEndogenous rhythms allow most organisms to synchronize their behavior and physiology with physical cycles that vary on a daily, lunar or annual cycle. Populations within species often show variation in the timing of functionally identical rhythms. This variation occurs because physical cycles may differ with geography. The purpose of this study was to determine whether hatching rhythms shown by fiddler crabs (Genus Uca) on one coastline could be entrained by the different tide patterns present at another coastline. To test this I transferred breeding females (Uca thayeri) from mangroves on the west coast of Florida to mangroves on the east coast. On the west coast, females are exposed to "mixed" tides; most release their larvae during the day or night (early summer), or during the day (mid- to late summer). On the east coast, females are exposed to "semidiurnal" tides; they release their larvae between dusk and midnight. After four weeks of exposure to the East Coast tides, crabs from the West Coast showed hatching rhythms identical to the resident crabs. This change indicates that the crabs show behavioral (phenotypic) "plasticity". These observations provide further evidence for the adaptive value of behavioral plasticity.

High nest incubation temperatures can result in numerous physiological and behavioral outcomes in sea turtle hatchlings, including body characteristics for efficient swimming. This project examined the effects of incubation temperature on yolk metabolization, body morphology, buoyancy, swimming kinematics, and blood chemistry to better understand variations in locomotor performance in loggerhead (Caretta caretta) sea turtle hatchlings of South Florida.

Show moreHigh nest incubation temperatures can result in numerous physiological and behavioral outcomes in sea turtle hatchlings, including body characteristics for efficient swimming. This project examined the effects of incubation temperature on yolk metabolization, body morphology, buoyancy, swimming kinematics, and blood chemistry to better understand variations in locomotor performance in loggerhead (Caretta caretta) sea turtle hatchlings of South Florida. Nest temperatures, body measurements, and blood samples were collected in conjunction with swim-trial force measurements and video recordings. Data suggest hatchlings from nests with higher incubation temperatures tend to be significantly smaller in size, less buoyant, and display lower power stroke frequencies. These variations between hatchling morphology and performance indicate hatchlings from high temperature nests (i.e., >33°C) may exhibit weaker swimming abilities. The results of this study provide a further understanding of the effect of incubation temperatures on hatchling physiology and early survival in their important frenzy period.

- Abstract/Description

Elevated yolk progesterone has been shown to impair prenatal, but facilitate postnatal auditory learning in bobwhite quail chicks. Elevated yolk testosterone has facilitated prenatal learning, but its effects on postnatal auditory learning in quail are unknown. Either testosterone or an oil vehicle was injected into bobwhite quail eggs prior to incubation. Control eggs were unmanipulated. Following hatching, chicks were exposed to a conspecific maternal call (A or B) for 240 min. At 48 hr,...
Show moreElevated yolk progesterone has been shown to impair prenatal, but facilitate postnatal auditory learning in bobwhite quail chicks. Elevated yolk testosterone has facilitated prenatal learning, but its effects on postnatal auditory learning in quail are unknown. Either testosterone or an oil vehicle was injected into bobwhite quail eggs prior to incubation. Control eggs were unmanipulated. Following hatching, chicks were exposed to a conspecific maternal call (A or B) for 240 min. At 48 hr, chicks were tested for their preference for the familiarized vs. novel call. All groups demonstrated a preference for the familiar call (p < .05), but minimal between group difference were found. Contrary to previous research, elevated yolk testosterone neither facilitated nor impaired postnatal auditory learning in bobwhite quail chicks. Further research will examine underlying mechanisms responsible for differential effects and explore if similar systems are involved in other species-typical processes such as social motivation.

Climate change has the potential to expose sea turtle nests to higher temperatures, which may negatively impact sea turtle hatchling vigor. In this study, loggerhead and green hatchlings were sampled from the Boca Raton, Florida beach and via lab incubation, and hatchling vigor was determined. Elevated nest temperatures decreased loggerhead and green turtle hatchling performance and corticosterone levels, with the most significant effects found in hatchlings exposed to maximum incubation...
Show moreClimate change has the potential to expose sea turtle nests to higher temperatures, which may negatively impact sea turtle hatchling vigor. In this study, loggerhead and green hatchlings were sampled from the Boca Raton, Florida beach and via lab incubation, and hatchling vigor was determined. Elevated nest temperatures decreased loggerhead and green turtle hatchling performance and corticosterone levels, with the most significant effects found in hatchlings exposed to maximum incubation temperatures above 35°C during late development. Lab-incubated loggerhead post-hatchling corticosterone levels and growth rates were also determined. The differences seen in corticosterone levels with overall nest incubation temperatures, mean temperatures during early, middle or late stages of development, and its negative correlation with hatchling performance improves our understanding of the underlying physiological mechanisms linking elevated incubation temperatures and sub-lethal physiological effects that may significantly impact hatchling survival, a critical step for sea turtle conservation in south Florida and elsewhere.

- Abstract/Description

The well-known Grimms' fairy tale "Sleeping Beauty" forms the subtext of two recent literary works, Rosario Ferre's novella "La bella durmiente" (1976) and Margaret Atwood's short story "Bluebeard's Egg" (1983). Both contemporary authors suggest that certain negative aspects inherent in the Sleeping Beauty paradigm should not persist in women's literature, unless the texts lead to transformation and self-realization of the heroines.

Show moreThe well-known Grimms' fairy tale "Sleeping Beauty" forms the subtext of two recent literary works, Rosario Ferre's novella "La bella durmiente" (1976) and Margaret Atwood's short story "Bluebeard's Egg" (1983). Both contemporary authors suggest that certain negative aspects inherent in the Sleeping Beauty paradigm should not persist in women's literature, unless the texts lead to transformation and self-realization of the heroines. This study demonstrates how the authors expose the fallacy in the paradigm, depart from it, and refigure it by transforming their heroines into characters quite distinct from the Grimm prototype. This study also suggests that Ferre's and Atwood's works serve as prototypes for feminine texts. As the characters distance themselves from hegemonic patriarchal traditions, each author's work is also removed from the referent of masculine literary traditions and returned to its origins, the oral tale.
