Transgenerational effects of temperature on egg and larval development in Cyprinodon variegatus

Transgenerational plasticity (TGP), a type of maternal effect, occurs when the environment experienced by one or both the parents prior to fertilization directly translates, without changing DNA sequences, into changes in offspring reaction norms. Evidence of such effects has been found in several traits throughout many phyla, and, although of great potential importance - especially in a time of rapid climate change - TGP in thermal growth physiology had never been demonstrated for vertebrates until the first experiment on thermal TGP in sheepshead minnows, who, given sufficient time, adaptively program their offspring for maximal egg viability and growth at the temperature experienced before fertilization. This study on sheepshead minnows from South Carolina and Connecticut investigates how population, parent temperature, and offspring temperature affect egg production, size, viability, larval survival and growth rates, whether these effects provide evidence of TGP, and whether and how they vary with length of exposure time (5, 12, 19, 26, 33 and 43 days) of the parents to the new experimental temperatures of either 26°C or 32°C. Several results are consistent with those obtained in the previous TGP study, which outline a sequence of events consisting of an initial adjustment period to the new temperatures, in which egg production decreases and no signs of TGP are present, followed by a shift to TGP (towards 26-33 days of exposure) in which parents start to produce more eggs which are better adapted to the new thermal environment. Other results present new information, such as signs of TGP in the parent temperature effect on egg sizes already around 20 days of exposure. The innovative idea of populations being able to adapt to rapidly shifting environments through non-genetic mechanisms such as TGP opens new possibilities of survival of species and will have important implications on ecology, physiology, and contemporary evolution.

Exhibits

The Carnegie Museum in downtown Houghton has a pair of Finnish-connected exhibits on display. A photographic exhibit titled “The Last Days of Italian Hall” by local photographer Eric Munch will be open to the public, as well as “Family Ties: Memorials to Those Lost in the 1913 Italian Hall Tragedy” by the Houghton-Keweenaw Genealogical Society. Munch’s photographs were taken in the early and mid 1980s, shortly after he moved to the Copper Country, and consist of both interior and exterior shots of the Hall, including some taken at the time of its demolition. The “Family Ties” exhibit is the result of a project through which HKGS members researched the genealogy of every Italian Hall tragedy victim. Also on exhibit is "From the Old School: Memories from the Old Houghton High School 1923-1989". Exhibit includes oral histories by former students and faculty recorded as a community project by students from the Class of 2013. Winning projects from the Western UP Science Fair (grades 4-8) are also being displayed. Carnegie Museum exhibit information can be obtained by calling (906) 482-7140.
