Pacific University is a private university located in Oregon, United States. The first campus began more than 160 years ago and is located about 38 km west of Portland in Forest Grove. Pacific University has four campuses within Oregon in the cities of Forest Grove, Eugene, Hillsboro and Woodburn.Established as Tualatin Academy in 1849, the school has an enrollment of more than 3,500 students. Founded by the United Church of Christ , the university's motto is Pro Christo et Regno Ejus, which is Latin for "For Christ and His Kingdom." Although the university is no longer formally associated with the UCC, it still maintains a close working relationship with the organization. The university is now a small private, independent liberal arts school, offering graduate programs in education, optometry, writing, health professions and business.

The foliage palatability hypothesis predicts that avian insectivores will preferentially forage in tree species with the greatest abundance of their arthropod prey, which in turn are associated with the tree's foliage nutrition and palatability. We tested this hypothesis in a novel Prosopis-Leucaena woodland in Puerto Rico by determining foraging preferences of five insectivorous bird species for six tree species (five alien, one native) and relating preferences to foliage arthropod biomass and leaf chemistry. The most frequently preferred tree species for foraging were the alien Prosopis juliflora (preferred by five bird species) and Pithecellobium dulce (preferred by four bird species). Both species had high foliage arthropod biomass, high N content, low lignin/N ratios, and low hemicellulose content. Compounds, previously known to affect herbivore responses to Albizia lebbeck and Leucaena leucocephala, may explain low arthropod biomass despite high N content in Albizia and avoidance of Leucaena by four bird species despite its high arthropod biomass. The native Bucida buceras had tough leaves with low N content, low arthropod biomass, and only one bird species showed a weak preference for foraging in it. Biomass of predaceous arthropods showed strong negative correlations with the ratios of lignin/N and hemicellulose/N. Some alien tree species had highly palatable foliage with high arthropod biomass and hence were preferred for foraging by avian insectivores as predicted by the foliage palatability hypothesis. High foliage palatability of some alien tree species may weaken the effect of enemy release in some novel plant communities. © 2013 Springer Science+Business Media Dordrecht. Source

This article is comprised by the description and analysis of the perceptions, customs and answers that poor Afro-Colombian women in the town of Buenaventura have to the problems arising from the assistance given to their reproductive health. Even though events like birth, death and sickness are natural happenings, first and foremost they have to be conceived as sociocultural facts whereby various population groups take action and construct their own techniques and ideologies. It is then from this scope that I approach the situations that lead these women to use the two main systems of health assistance that are in the town; the hegemonic or biomedical system and the traditional system. This article aims at elucidating how the decision of these women to opt for one way of assistance or another is strongly influenced by geographical order, cultural, social and economic factors. The studyholds an interdisciplinary character as it was formulated using several viewpoints such as social anthropology, health anthropology, gender studies and sociology. Source

In Andisols of the Cajibio municipalities, Cauca department and Sevilla, Valle del Cauca department, Colombia, the effect of soil use with forest Systems was evaluated, guadua (Guadua angustifolia K.), coffee crops (Coffea arábiga Caturra cultivar), with total sun exposure, shaded with guamo (Inga sp), walnut tree shadow and Brachiaria pasture over different organic matter compounds. Soil samples were taken in a Typic Melanudand located in the Cauca department to 1740 m.a.s.n. and a Typic Haplustand in Sevilla, Valle del Cauca, department to 1660 m.a.s.n. Soils were characterized by determination of physical and chemical properties; humic substances were obtained with sequential extraction solutions tetraborate, pyrophosphate and sodium hydroxide prior granulometric separation by wet sieving. Then purified and characterized humic and fulvic acids by different analytical and spectroscopic techniques. Were found significantly differences in the properties evaluated by the effect of the use and soil type. The higher acidity was performed at the Typic Melanudand (pH < 5.6). Typic Haplustand shows abrupt changes in going from slightly acidic pH (6.2) to highly acidic (< 5.5) by the change in land use. Typic Melanudand had higher organic carbon content. The humus was highert han fresh in both soils, yields on extraction of humic substances changed with soil use and content of humic acids was higher than the fulvic acids. Relations among both compounds showed differences E4/E6 use and soil type for humic and fulvic acids. Hydrophobicity indices were higher than 1.0 than humic acids and fulvic acids lower than 1.0. Acid fulvic performs a greatest condensation degrees in the Typic Melanudand soil. Source

Objective: To describe the clinical, positron emission tomography (PET), pathological, and genetic findings of a large kindred with progressive neurodegenerative phenotypes in which the proband had autopsy-confirmed corticobasal degeneration (CBD). Methods: Five family members, including the proband, were examined neurologically. Clinical information from the other family members was collected by questionnaires. Three individuals underwent PET with 11C-dihydrotetrabenazine and 18F-fludeoxyglucose. The proband was examined post-mortem. Genetic studies were performed. Results: The pedigree contains 64 individuals, including 8 affected patients. The inheritance is likely autosomal dominant with reduced penetrance. The proband developed progressive speech and language difficulties at the age of 64 years. Upon examination at the age of 68 years, she showed non-fluent aphasia, word-finding difficulties, circumlocution, frontal release signs, and right-sided bradykinesia, rigidity, and pyramidal signs. She died 5 years after disease onset. The neuropathology was consistent with CBD, including many cortical and subcortical astrocytic plaques. Other family members had progressive neurodegenerative phenotypes - two were diagnosed with parkinsonism and behavioral problems, two with parkinsonism alone, one with amyotrophic lateral sclerosis alone, one with dementia, and one with progressive gait and speech problems. PET on three potentially affected individuals showed no significant pathology. Genetic sequencing of DNA from the proband excluded mutations in known neurodegenerative-related genes including MAPT, PGRN, LRRK2, and C9ORF72. Conclusions: Families with such complex phenotypes rarely occur. They are usually associated with MAPT mutations; however, in this family, MAPT mutations have been excluded, implicating another causative gene or genes. Further genetic studies on this family may eventually disclose the etiology. © 2014 Elsevier Ltd. Source

Dry forests areas in the Caribbean region of Colombia have been deeply impacted lagging far precious few remnants and traces of its original dynamics, so the objective of this research is to study the structure and seasonality variation of phytophagous scarab beetles (Coleoptera: Scarabaeidae) in the Reserva Campesina La Montaña. Nine samples were obtained from January to September 2011. Four points distanced approximately 150 m were marked. In each one, a light trap was settled, for a total of 4 (2 white and 2 violet) operating since 18:00 until 24:00 h. 3,007 individuals and 18 species clustered in 3 subfamilies were collected: Rutelinae (7 species), Melolonthinae (6 species) and Dynastinae (5 species). Melolonthidae were the most abundant and Liogenys quadridens its most abundant specie (1,667 individuals), characterized by an important pest of semestral crops, and wide distribution in the Colombian Caribbean. The highest richness (16) was obtained in May, while April presented higher abundance (1,421), which coincides with the beginning of the rainy season, showing a marked seasonality showed by the analysis of similarity Anosim (R = 0.277, p < 0.003). © 2015 Universidad Nacional Autonoma de Mexico, Instituto de Biologia.
