行为.
杰西卡·卡斯蒂略·瓦尔达罗, assistant professor of biology at 圣何塞州立大学, 记得那个夏天她爱上了大自然. 她只有5岁.
The Santa Ana, California, native and her family piled into their red 1985 Chevy Astrovan 去美国六个不同的地方旅行.S. 国家公园，包括锡安国家公园， 黄石公园和大峡谷.
“I remember seeing coyotes, bison, deer, moose, bighorn sheep, squirrels and chipmunks,” 卡斯蒂略·瓦尔达罗回忆道. “我太兴奋了，我知道我想要 在户外大自然中工作. 当我回想起我决定成为一名野生动物的时候 生物学家，肯定是在旅途中.”
Today, Castillo Vardaro studies the American pika — a small rabbit-like mammal living in the mountains of western North America — to learn how climate 改变 and human 行为影响本地野生动物.

While her research has shed light on the ways humans can affect their environment, it serves another purpose: to empower students to become scientists, especially those 谁可能没有这样的机会.
Since she joined San José State in 2019, Castillo Vardaro has tried to remove barriers to research opportunities for underrepresented minority students, including Latino/a, 拉丁裔和西班牙裔学生. 她还致力于让这些学生走上这条道路 为了成功，同时培养社区意识.
“在我的工作中，我是一名讲师，一名研究员和一名导师，”她分享道. “我用所有的 three of those parts of my role to increase participation of underrepresented groups 在科学领域，更普遍，在野生动物研究领域，更具体.”

Castillo Vardaro and two of her graduate students spent this past summer hiking, backpacking and camping in the mountains of northwestern Nevada and in Sequoia and Kings Canyon 国家公园. 他们的使命? 收集鼠兔的粪便，他们和本科生 学生们随后将在卡斯蒂略·瓦尔达罗的实验室进行分析.
“We also were counting and identifying all the plants around the areas where the pikas 卡斯蒂略·瓦尔达罗说. “我们研究了过去和现在有哪些植物 比较它们选择吃的植物.”
了解鼠兔吃什么以及为什么吃，可以揭示它们是如何吃的 适应环境以及什么会导致它们灭绝，卡斯蒂略 Vardaro解释.

For example, a pika could choose to eat something less nutritious but more readily 可用. 也许因为干旱，人们喜欢的食物不再有了，更高 temperatures or even humans manipulating vegetation for cattle grazing, Castillo Vardaro 说. 这可能会揭示人类行为对动物的潜在长期影响 鼠兔的栖息地和食物来源.
这些发现也可能对地球产生影响.
“Think about squirrels, racoons and opossums in the San José area,” Castillo Vardaro 说. “这对他们的人口意味着什么，他们过去能够旅行 from the hills in the East Bay all the way to Santa Cruz in the peninsula — but now 在他们的道路中间有一座大城市?
“Or what does it mean if we put a big six-lane highway through some species’ natural 栖息地? 通过了解气候变化或人类活动带来的威胁， 我们可能会限制我们的影响，以帮助这些种群生存.”
圣何塞市中心的实地调查
卡斯蒂略·瓦尔达罗深知，学习成为一名野生生物学家可以 是昂贵的. 进入这一领域需要经验，这最终可能会成为一笔财富 这是学生的负担，她解释说.
As an undergraduate at the University of California, Berkeley, Castillo Vardaro found a paid part-time job at the university’s Museum of Vertebrate Zoology, where she gained 这段经历帮助她迈出了第一步. 但不是每个人都这么幸运， 她说.
她解释说:“学生们通常负担不起无薪的实验室工作。. “这是真的 当你已经需要一到两份工作时，很难获得合适的经验 工作来支付账单.”
Even those who might be able to sacrifice income for volunteer experience could end 因为重要的实地研究机会的成本而却步.
“A lot of these opportunities will ask students to come volunteer for the summer — and to bring their own tent, and a $300 backpack, $200 boots and a $100 jacket,” she 解释. “这些机会花费了很多钱，这是一个真正的挑战 许多学生.”
这就是为什么卡斯蒂略·瓦尔达罗试图消除这些类型的原因之一 of obstacles by not only offering paid opportunities for graduate and undergraduate 学生们在她的实验室里，还把实地研究带到校园里.
In January 2020, she jumpstarted an urban ecology research project on the 菠菜网lol正规平台 campus. Students could study the different varieties of squirrels (there are two you’ll find in most parts of San José, Castillo Vardaro 说) to better understand their adaptation 习惯.
The project was put on hold during the pandemic, but Castillo Vardaro hopes to revive 很快就.
“这个项目背后的主要动机之一是试图让学生们拥有 these practical, tangible experiences without having to travel and invest,” 她说. “They can walk around campus and observe squirrels and learn lots of field techniques without needing to go up to the mountains, plus gain analytical and lab experience.”
研究之外
曾有一段时间，22岁的生物科学硕士艾米丽·哈杰斯(Emily Hadjes)认为她会这样做 永远不要进研究生院.
“I thought that I did not belong,” recalled Hadjes, who is of Peruvian heritage and 被认为是拉丁人. 她是收集样本的研究生之一 卡斯蒂略·瓦尔达罗.
“I used to have this idea in my head that a scientist had to be a certain way, and 不管那是什么，我都不适合，”她说.
卡斯蒂略·瓦尔达罗指出，哈吉斯的看法很普遍. 这是原因之一 她是学校的指导老师 奇卡诺人和美洲原住民科学促进会 在菠菜网lol正规平台. 她想要消除拉丁裔和土著学生的许多观念 可能具备成为科学家的条件.
“STEM专业的学生面临着很多挑战，”她说. “很多人可能会 come into their first year thinking, ‘I’m going to be a biology or chemistry major,’ and then they don’t do so well in their intro classes and think, ‘Oh well, I guess 我不够好.然后，他们会换专业.
“In reality, you could fail your bio or chem class, but still end up perfectly successful,” 她继续说道. “大学和高中不同，所以有很多原因 为什么有人在课堂上表现不好.”
SACNAS is about providing a community for these students so that they don’t feel isolated 卡斯蒂略·瓦尔达罗解释说，当遇到逆境时，他们也不会轻易放弃. By offering students of similar backgrounds an opportunity to network with 一个 another, plus tools for professional development, 她说 students can feel uplifted and supported.
Learning from Castillo Vardaro helped Hadjes put to rest any of her self doubt about 她作为科学家的未来.
“Dr. 卡斯蒂略·瓦尔达罗理解我，相信我，”她说. “Being mentored by some一个 who is also of Latinx descent has been such an uplifting experience. 她让我觉得自己属于这里，也属于科学领域.”
Michael Hernandez, ’22 MS Biology, another student who worked with Castillo Vardaro 整个夏天，我同意了.
“I have had a number of jobs in which I may have been the only Latinx member present, so having a [principal investigator] who looks like me has been a refreshing 改变. It reinforces the notion that I can succeed in my studies and career objectives, and 在我选择的领域里有我的一席之地.”
Castillo Vardaro understands the value of learning from some一个 who comes from a similar background. 她很早就意识到，当她加入圣何塞州立大学时，她不是 她刚刚进入教职岗位——她是在满足需求. 她甚至没有露面 up on campus once she was hired before a buzz started circulating about a new Latina 科学教授.
“学生们给我发邮件，告诉我他们想见我，”她回忆说.
“在成长过程中，我从来没有遇到过像我这样的教授、榜样或导师 或者分享我的经历. 我来圣何塞州立大学的动机是 主要是一所本科院校，也是一所为西班牙裔服务的院校. 学生 身体确实反映了该地区的人口结构.
“有时我喜欢淡出背景，专注于自己，但我做到了 这个重要的角色内置，要可见. 所以我想尽力做到最好.”
