These programs provide first-year students with amazing experiences that are excellent preparation for the upcoming school year.

Interdisciplinary Research Faculty members, graduate researchers, and undergraduate students collaborate to conduct expert research on topics ranging from acoustics to zombie ants.
Global Service and Impact Penn State students, faculty, staff, and alumni are creating positive impact in their communities—in Pennsylvania and beyond. Top 25 U. The video then transitions to shots of water running through a creek bed and Laurie walking outside with a student across a covered bridge.
Interspersed are scenes of Laurie talking to camera in a studio, nurses and patients in a hospital, the We Are statue and other campus scenes.
The video closes with Laurie sitting at a desk and laying down her pen. Proper masks and mask-wearing are critical as semester begins. The number of viruses present was positively correlated with Varroa levels, but was not correlated with colony size or hygienic behavior. We also found Nosema apis both at the coast and at an inland sight near Uganda.
Bees in the far north of Kenya did not have Varroa , viruses or Nosema. We found that levels of Varroa were positively correlated with elevation, suggesting that environmental factors may play a role in honey bee host-parasite interactions.
Only a small number of pesticides at low concentrations were found. Based on our findings these factors do not yet appear to be impacting Kenyan bee populations. Thus chemical control for Varroa and Nosema are not necessary for Kenyan bees at this time. This study provides baseline data for future analyses of the possible mechanisms underlying resistance to and the long-term impacts of these factors on African bee populations.
As an extension of this study, in collaboration with South Eastern Kenya University, we have initiated a series of projects that monitor bee health over time and look at management practices as well as other potential stressors. A primary goal of this work is to connect scientific research and development to beekeepers, farmers and government and NGOs to improve agricultural productivity. Nutrition-sensitive Agriculture and Pollinators - Pollinators are essential for global nutrition and sustainable food security.
Over the past century much development has focused on increasing mere caloric intake of staple crops with micronutrients as a supplement. Because most of our major global food crops benefit from pollinators any nutrition-sensitive agriculture will require figuring pollinators into the equation.
Many pollinator dependent fruits, vegetables, and nuts, provide vitamins, minerals, fats and other micronutrients, and thus pollinators form a crucial line of defense against micronutrient deficiencies in developing countries and in diverse health diets once undernutrition declines.
Furthermore, the productivity of many high value crops grown in the developing world, such as cacao, coffee, and cashews, is strongly tied to pollination services. Indeed, the amount of animal pollinated crops grown globally has increased significantly in the last fifty years, making both developed- and developing world countries increasingly dependent on pollinator populations for food security and production of economically important crops.
Host Plant Choice and Pollinator Landscapes- Poor nutrition is implicated as one factor contributing to pollinator declines across the global.
