De Anza College is a 112-acre community college located in Cupertino, California. It was founded in 1967 on the site of the Beaulieu Winery and is named after the Spanish explorer Juan Bautista de Anza. Along with the arrival and growth of Apple Computer, the presence of De Anza College contributed significantly to the growth of Cupertino from a small town to an industrial city and an integral part of Silicon Valley. It consistently ranks #1 or #2 in the state for the total number of students who annually transfer to University of California and California State University campuses. The college is also the home of the California History Center, housed in a mansion called "Le Petit Trianon". The current president of De Anza college is Brian Murphy, replacing Martha Kanter who later became the Under Secretary of Education for the Obama Administration. The average class size at De Anza is 35, and approximately 2,800 students transfer per year. It also attracts a heavy international student population.De Anza College is part of Silicon Valley's Foothill-De Anza Community College District, which also administers Foothill College in nearby Los Altos Hills, California. The district serves the cities of Cupertino, Los Altos, Los Altos Hills, Mountain View, Palo Alto, Sunnyvale and San Jose. The district headquarters is on the Foothill campus.Each year, De Anza invites several celebrities and dignitaries for public speaking engagements at its main theater, the Flint Center. De Anza once held the second largest pow-wow in the Bay Area, but the pow-wow organizers moved the event in 2005.De Anza holds a monthly flea market in its parking lot, which has become a community tradition as well as major source of income for the De Anza Associated Student Body . With a budget of over 1 million dollars, the DASB has one of the biggest student budgets of any community college in California.De Anza formerly had their own campus police. They used to wear slacks and polo shirts, and officers were unarmed. The department was not a POST participating agency and in 2001, the campus police departments at De Anza and Foothill College were merged to become the Foothill-De Anza College District Police.

Prehistoric farmers in arid and semiarid ecosystems commonly used rock alignments to concentrate water and sediments on their fields. Previous research has emphasized the importance of runoff from organic matter-rich uplands as a mechanism for soil nutrient replenishment. However, eolian inputs to these dryland ecosystems might also contribute substantially to mineral-derived nutrient pools. We explored the relative importance of eolian deposition, prehistoric agriculture, and the presence of rock alignments on soil properties in a semiarid grassland in Arizona. Subsurface soils behind natural rock alignments are finer in texture than soils unbound by rock alignments, while subsurface soils behind agricultural rock alignments coarsen relative to unbound soils. Neither rock alignments nor estimated crop yields had detectable effects on mineral-derived nutrient pools. In contrast, eolian deposition is an important source of soil mass and nutrients to modern soils. While dust deposition likely reduced soil heterogeneity across this landscape, it could have also contributed to the sustainability of prehistoric agriculture. © 2014 Wiley Periodicals, Inc. Source

Limnopithecus is a small-bodied catarrhine genus that is widespread throughout early Miocene sites in East Africa. Although two species of this genus have been described - Limnopithecus legetet (type species) and Limnopithecus evansi - they are poorly known anatomically and their systematic positions remain unresolved. Here, we provide detailed descriptions and comparisons for two well-preserved maxillary specimens that we attribute to L. evansi. These specimens come from the type locality of the species, Songhor in western Kenya, and add greatly to our knowledge of its dentognathic morphology. Together, they preserve the entire unilateral upper dentition, with overlapping elements demonstrating conspecificity, and provide new information about I2 morphology and aspects of the palate, nasal aperture, and maxillary sinuses.Detailed morphological comparisons suggest that specimens referred to Limnopithecus from Songhor, Koru, and Rusinga share a unique I2 morphology not found in any other early Miocene catarrhine. This argues in favor of congeneric status for L. evansi and L. legetet. Moreover, features such as a broad palate, premolar morphology, and the relative proportions of the premolars of L. evansi distinguish it from Lomorupithecus harrisoni, another early Miocene catarrhine from Napak, Uganda. This finding challenges a recently proposed taxonomic interpretation that Lomorupithecus and L. evansi are conspecific. Our results underscore the distinctiveness of L. evansi and Lo. harrisoni, thereby reaffirming the validity of the taxon Lo. harrisoni and indicating that the Songhor and Napak catarrhine communities were relatively distinct, despite their apparent contemporaneity. © 2016 Elsevier Ltd.

A mandible of Rangwapithecus gordoni from the early Miocene site of Songhor, Kenya, provides additional information about this relatively poorly known taxon. The R.gordoni sample is small, being composed of dental and a few gnathic parts. The fossil described here provides examples of previously unknown dental and mandibular anatomy, and confirms former reassignments of isolated anterior teeth based on less certain evidence. The phylogenetic status of Rangwapithecus, its distribution, and paleobiology are briefly reviewed. Rangwapithecus shows a suite of dental and gnathic features that warrants its generic distinction from Proconsul. Derived features shared with Nyanzapithecus and Turkanapithecus indicate that it is an early member of the subfamily Nyanzapithecinae. Its molar morphology suggests a considerable component of folivory in its diet. A review of the hypodigm shows Rangwapithecus to be restricted to Songhor. This distribution parallels that of Limnopithecus evansi, and is mirrored by Limnopithecus legetet and Micropithecus clarki suggesting that Songhor may have differed ecologically from other more or less contemporary sites in the region. © 2013 Elsevier Ltd.

Phenotypic plasticity is often considered important for invasive plant success, yet relatively few studies have assessed plasticity in both native and invasive populations of the same species. We examined the plastic response to temperature for Bromus tectorum populations collected from similar shrub-steppe environments in the Republics of Armenia and Georgia, where it is native, and along an invasive front in California and Nevada. Plants were grown in growth chambers in either ‘warm’ (30/20 °C, day/night) or ‘cold’ (10/5 °C) conditions. Invasive populations exhibited greater adaptive plasticity than natives for freezing tolerance (as measured by chlorophyll a fluorescence), such that invasive populations grown in the cold treatment exhibited the highest tolerance. Invasive populations also exhibited more rapid seedling emergence in response to warm temperatures compared to native populations. The climatic conditions of population source locations were related to emergence timing for invasive populations and to freezing tolerance across all populations combined. Plasticity in growth-related traits such as biomass, allocation, leaf length, and photosynthesis did not differ between native and invasive populations. Rather, some growth-related traits were very plastic across all populations, which may help to dampen differences in biomass in contrasting environments. Thus, invasive populations were found to be particularly plastic for some important traits such as seedling emergence and freezing tolerance, but plasticity at the species level may also be an important factor in the invasive ability of B. tectorum. © 2014, Springer International Publishing Switzerland.
