California University of Pennsylvania is a public university located in California, Pennsylvania, United States. Founded in 1852, it is a member of the Pennsylvania State System of Higher Education. Cal U's enrollment was approximately 9,400 in 2010 and has increased the past few years.The main campus consists of about 38 buildings situated on 92 acres . Another 9-acre facility is located near the main campus. An additional 98-acre recreation complex, George H. Roadman University Park, is located one mile from campus and includes a football stadium, various sports facilities, and picnic facilities. The University's student association also owns 98 acres at SAI Park, located near Roadman Park. Cal U has a satellite campus in Canonsburg as well as a large virtual school. Wikipedia.

Kirtland's warbler is one of many conservation-reliant species listed under the Endangered Species Act (ESA). This species has met recovery goals, but removing it from the protections of the ESA is problematic because of its reliance on ongoing conservation. We define conservation management agreements (CMAs) and describe how they may provide a mechanism to protect conservation-reliant species after delisting. We suggest that CMAs should include four major elements: (1) a conservation partnership capable of implementing management actions at conservation-relevant scales, (2) a conservation management plan based on the management actions in the species' successful recovery plan, (3) sufficient financial resources to provide the required conservation management, and (4) legal enforcement. We use the efforts of the Kirtland's Warbler Recovery Team as a case study of the application of CMAs to build and maintain public and private partnerships to ensure continuing management for this species after delisting. © 2012 by American Institute of Biological Sciences.

Direct assessment of food resources may be unreliable if those resources fluctuate or are not easily detected. Foragers under such conditions may instead use indirect cues to assess the quality of potential foraging sites. Young individuals may be particularly likely to use indirect cues to compensate for their inexperience and to reduce assessment costs. We investigated the cues juvenile crab spiders (Mecaphesa asperata) use when selecting foraging sites. First, we examined whether spiderlings' site preference was influenced by prey abundance, a direct cue of site quality. We next investigated whether juvenile crab spiders assessed potential sites using indirect cues, including flower quality, cues left by conspecifics, or conspecifics themselves. We found spiderlings did not use prey abundance to assess foraging sites, but instead used indirect cues when choosing where to forage. Spiderlings preferred sites that would attract larger numbers of their arthropod prey, choosing blooming inflorescences over both senescing inflorescences and inflorescences with buds. Hungry spiderlings, unlike individuals that had recently fed, also used cues left by conspecifics, preferring sites on which a conspecific had previously foraged. Finally, spiderlings avoided sites with larger numbers of conspecifics, but were attracted to sites with relatively low abundances of conspecifics, indicating that spiderlings are able to weigh the possibility of improving their foraging success by joining conspecifics against the potential costs of being in larger groups. We show here that young, relatively inexperienced animals do not always directly assess prey abundance when choosing foraging sites, but that these individuals are capable of detecting and using a variety of indirect cues to evaluate foraging site quality. © 2013 Dipartimento di Biologia, Università degli Studi di Firenze, Italia.

Background/Aim: We have been exploring a prevention approach to the problem of drug resistance which develops during ovarian cancer chemotherapy. We have previously described an in vivo model of the development of resistance to the chemotherapy drug cisplatin in xenografts, and the prevention of this resistance by selenium compounds. However, a different platinum-based drug, carboplatin, is frequently utilized in ovarian cancer treatment. The aim of the present study was to design a model for the induction of resistance by carboplatin in vivo. Materials and Methods: Tumors were initiated in immunodeficient mice by subcutaneous inoculation of A2780 human ovarian tumor cells. The sensitivity of the resulting tumors to therapy was determined by measuring the effect on tumor growth of a single intraperitoneal (i.p.) treatment with a high dose of carboplatin. Results: The growth of control tumors was completely (although temporarily) stopped by this treatment; however, a single pre-treatment with a low i.p. dose of carboplatin resulted in the rapid development of resistance to carboplatin, and cross-resistance to cisplatin. Pre-treatment with selenite in addition to carboplatin prevented the induction of resistance. When cells from these pre-treated tumors were transplanted to new animals, the derivative tumors retained the sensitive or resistant phenotype of their tumor of origin. Conclusion: Selenite can prevent the induction of resistance by carboplatin in human ovarian tumors, and thus may offer an approach to extending the long-term efficacy of platinum chemotherapy.

Two new species of Begonia (Begoniaceae) from Andean South America are described and illustrated. Begonia heliantha Tebbitt is classified in B. sect. Eupetalum and is known from the Puno Region of Peru and has also been tentatively identified from photographs taken in La Paz Department of Bolivia. Begonia urubambensis Tebbitt is affiliated with a group of species currently classified in B. sect. Knesebeckia. This group of species is informally named here the B. acerifolia group. Begonia sect. Knesebeckia is polyphyletic since the B. acerifolia group does not include the type species of the section. Ongoing research aims to recircumscribe this section. Begonia urubambensis is not assigned to a section given the changes needed to the sectional classification system. Begonia urubambensis is a narrow endemic of La Convención Province (Cusco Region) of Peru. Begonia heliantha is assigned the IUCN category of Data Deficient (DD), while B. urubambensis is assigned the IUCN category of Vulnerable (VU-D2). © Copyright 2016 Trustees of the Royal Botanic Garden Edinburgh.
