Harrisonburg native and biology professor Kristine Grayson<\/a> comes to 91短视频 to present a Suter Science Seminar<\/a> on a common problem for the conservation and management of endangered populations.<\/p>\n She\u2019ll share her research about tuatara (Sphenodon punctatus<\/em>), an endemic and rare reptile of New Zealand, in a seminar Friday, Nov. 6, at 4 p.m. in Suter Science Center 106.<\/p>\n \u201cIn many species, offspring sex is not determined by chromosomes but instead develops based on environmental conditions,\u201d explains Grayson, who teaches in the biology department at University of Richmond. \u201cMy research on tuatara living in islands offshore of New Zealand examined the potential for increased environmental temperature and sex ratio bias to endanger an isolated population.\u201d<\/p>\n Despite that populations may appear numerically stable, the sex ratio in tuatara populations may be \u201can underappreciated threat to long-term viability,\u201d she said.<\/p>\n Professor Jim Yoder<\/a>, who with his wife Kathy has led three cross-cultural trips<\/a> to New Zealand in 2010, 2012 and 2015<\/a>, invited Grayson to speak. The groups he\u2019s led focus on conservation biology and the effects of invasive species, in addition to work with the indigenous Maori people, and the 2015 summer group met with Grayson\u2019s colleagues (she was back in the States by that time) and toured the lab where she had worked.<\/p>\n \u201cTuatara are a great case study for the ‘Conservation Biology’ class as well as my first-year ‘Concepts in Biology’ class, as we are currently studying evolutionary biology and will be focusing on invasive species, which is the primary threat to tuatara, later this semester,\u201d he said.<\/p>\n Grayson grew up in Harrisonburg, the daughter of two professors. Her mother, Joann Grayson, is a professor of psychology at James Madison University (JMU) and an expert in the field of child and family abuse. Her father, Phillip Grayson<\/a>, is a scenery and lighting expert who retired after 26 years at JMU and is on the adjunct faculty at 91短视频.<\/p>\n In her youth, Grayson says she thought about studying environmental law, but her love of interacting with animals and the environment won over. She graduated from Davidson College in 2003 and decided to take a year off, unknowingly sowing the seeds of a future post-doctoral fellowship when she attended a conference in Australia on amphibians and reptiles. \u201cThe head of the tuatara research project mentioned that I should get in touch if I ever wanted to work on tuatara.\u201d<\/p>\n At University of Virginia, she focused her dissertation research on migratory trade-offs of amphibians. But she never forgot the tuatara, and in 2010, six years later, she emailed the director of the project that she had met so many years ago in New Zealand.<\/p>\n That led to a grant proposal with the National Science Foundation, and in 2011, \u201cwe packed up our family to move to New Zealand for a year and a half.\u201d<\/p>\n Grayson says the experience of living and working in a different country, and best of all for the biologist, \u201cseeing different ecosystems,\u201d was rewarding, but also challenging. Based out of Victoria University of Wellington, she had to learn \u201ca whole new research system and the logistics of doing research in a totally different place.\u201d<\/p>\n \u201cTuatara are highly protected in New Zealand and the permitting process to conduct research is quite extensive, as well as the logistics of getting to the islands where they live,\u201d she said. \u201cThis was much different than walking up to a pond in your backyard with a net to catch salamanders!\u201d<\/p>\n Grayson\u2019s current research also examines the spread potential of gypsy moth, an invasive forest pest, at the southern invasion front.<\/p>\n","protected":false},"excerpt":{"rendered":" Harrisonburg native and biology professor Kristine Grayson comes to 91短视频 to present a Suter Science Seminar on a common problem for the conservation and management of endangered populations. ... read more about Harrisonburg native and biology professor to talk about research with tuatara, a rare New Zealand reptile<\/span><\/a><\/p>","protected":false},"author":1,"featured_media":25790,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5590,5643,5593,7682],"tags":[10709,11711],"feature":[],"class_list":["post-25786","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-biology","category-environmental-sustainability","category-intercultural","category-suter-science-seminar","tag-jim-yoder","tag-phillip-grayson"],"yoast_head":"\n
