Pinus Sabiniana) in Oregon Frank Callahan PO Box 5531, Central Point, OR 97502
Discovering Gray Pine (Pinus sabiniana) in Oregon Frank Callahan PO Box 5531, Central Point, OR 97502 “Th e tree is remarkable for its airy, widespread tropical appearance, which suggest a region of palms rather than cool pine woods. Th e sunbeams sift through even the leafi est trees with scarcely any interruption, and the weary, heated traveler fi nds little protection in their shade.” –John Muir (1894) ntil fairly recently, gray pine was believed to be restricted to UCalifornia, where John Muir encountered it. But the fi rst report of it in Oregon dates back to 1831, when David Douglas wrote to the Linnaean Society of his rediscovery of Pinus sabiniana in California. In his letter from San Juan Bautista, Douglas claimed to have collected this pine in 1826 in Oregon while looking for sugar pine (Pinus lambertiana) between the Columbia and Umpqua rivers (Griffin 1962). Unfortunately, Douglas lost most of his fi eld notes and specimens when his canoe overturned in the Santiam River (Harvey 1947). Lacking notes and specimens, he was reluctant to report his original discovery of the new pine in Oregon until he found it again in California (Griffin 1962). Despite the delay in reporting it, Douglas clearly indicated that he had seen this pine before he found it in California, and the Umpqua region has suitable habitat for gray pine. John Strong Newberry1 (1857), naturalist on the 1855 Pacifi c Railroad Survey, described an Oregon distribution for Pinus sabiniana: “It was found by our party in the valleys of the coast ranges as far north as Fort Lane in Oregon.” Fort Lane was on the eastern fl ank of Blackwell Hill (between Central Point and Gold Hill in Jackson County), so his description may also include the Th e lone gray pine at Tolo, near the old Fort Lane site, displays the characteristic architecture of multiple Applegate Valley. -

Revista Mexicana de Ciencias Forestales Vol. 10 (53) May – June (2019) DOI: https://doi.org/10.29298/rmcf.v10i53.173 Article Diversidad y estructura vertical del bosque de pino– encino en Guadalupe y Calvo, Chihuahua Diversity and vertical structure of the pine-oak forest in Guadalupe y Calvo, Chihuahua Samuel Alberto García García1, Raúl Narváez Flores1, Jesús Miguel Olivas García1 y Javier Hernández Salas1 Resumen Se evaluaron áreas con y sin manejo forestal de la Umafor 0808 Guadalupe y Calvo, Chihuahua; gestionadas mediante el Método Mexicano de Ordenación de Bosques Irregulares (MMOBI). Se analizó y comparó la información de conglomerados del Inventario Nacional Forestal y de Suelos (2004-2009); 95 en masas con manejo y 27 sin manejo. Se determinó la estructura vertical por medio de la regeneración natural, pisos de altura de los árboles y posición sociológica. Las especies con distribución continua, desde el piso inferior de la regeneración hasta el piso arbóreo superior en el bosque con manejo fueron: Pinus durangensis, P. arizonica, P. ayacahuite, P. herrerae y P.engelmannii; mientras que, en el bosque sin manejo se registraron: P. durangensis y P. arizonica. Las principales diferencias entre los bosques estudiados correspondieron al promedio de altura en el piso arbóreo superior; en los bosques con manejo fue de 30.16 m y en los sin manejo, su valor fue de 21.86 m; además, se observó una mayor regeneración de P. durangensis en los primeros. Respecto a la diversidad de especies, no hubo diferencia significativa entre ambos tipos de bosque (P>0.05). Por lo anterior, se concluye que, de acuerdo con la información analizada, la regulación del aprovechamiento maderable con el MMOBI permite mantener la diversidad estructural y de especies, similar a la de un bosque natural sin manejo. -
Jordan Beans RA RMO Dir
Importation of Fresh Beans (Phaseolus vulgaris L.), Shelled or in Pods, from Jordan into the Continental United States A Qualitative, Pathway-Initiated Risk Assessment February 14, 2011 Version 2 Agency Contact: Plant Epidemiology and Risk Analysis Laboratory Center for Plant Health Science and Technology United States Department of Agriculture Animal and Plant Health Inspection Service Plant Protection and Quarantine 1730 Varsity Drive, Suite 300 Raleigh, NC 27606 Pest Risk Assessment for Beans from Jordan Executive Summary In this risk assessment we examined the risks associated with the importation of fresh beans (Phaseolus vulgaris L.), in pods (French, green, snap, and string beans) or shelled, from the Kingdom of Jordan into the continental United States. We developed a list of pests associated with beans (in any country) that occur in Jordan on any host based on scientific literature, previous commodity risk assessments, records of intercepted pests at ports-of-entry, and information from experts on bean production. This is a qualitative risk assessment, as we express estimates of risk in descriptive terms (High, Medium, and Low) rather than numerically in probabilities or frequencies. We identified seven quarantine pests likely to follow the pathway of introduction. We estimated Consequences of Introduction by assessing five elements that reflect the biology and ecology of the pests: climate-host interaction, host range, dispersal potential, economic impact, and environmental impact. We estimated Likelihood of Introduction values by considering both the quantity of the commodity imported annually and the potential for pest introduction and establishment. We summed the Consequences of Introduction and Likelihood of Introduction values to estimate overall Pest Risk Potentials, which describe risk in the absence of mitigation. -

Biological responses of aphids (Hemiptera: Aphididae) when fed three species of forage grasses Heloise A. Parchen1 and Alexander M. Auad2,* Abstract In Brazil, the forage species Brachiaria spp., Pennisetum purpureum (Schumacher), and Cynodon dactylon (L.) (Poaceae) are important components in the feed that is used to rear animals for meat and milk production. Aphids are among the insects that feed on these forage species and, at high population levels, greatly reduce the amount and quality of forage. -
Native Trees of Mexico: Diversity, Distribution, Uses and Conservation
Native trees of Mexico: diversity, distribution, uses and conservation Oswaldo Tellez1,*, Efisio Mattana2,*, Mauricio Diazgranados2, Nicola Kühn2, Elena Castillo-Lorenzo2, Rafael Lira1, Leobardo Montes-Leyva1, Isela Rodriguez1, Cesar Mateo Flores Ortiz1, Michael Way2, Patricia Dávila1 and Tiziana Ulian2 1 Facultad de Estudios Superiores Iztacala, Av.

ABSTRACT Background. Mexico is one of the most floristically rich countries in the world. Despite significant contributions made on the understanding of its unique flora, the knowledge on its diversity, geographic distribution and human uses, is still largely fragmented. Unfortunately, deforestation is heavily impacting this country and native tree species are under threat. The loss of trees has a direct impact on vital ecosystem services, affecting the natural capital of Mexico and people's livelihoods. Given the importance of trees in Mexico for many aspects of human well-being, it is critical to have a more complete understanding of their diversity, distribution, traditional uses and conservation status. We aimed to produce the most comprehensive database and catalogue on native trees of Mexico by filling those gaps, to support their in situ and ex situ conservation, promote their sustainable use, and inform reforestation and livelihoods programmes. Methods. A database with all the tree species reported for Mexico was prepared by compiling information from herbaria and reviewing the available floras. Species names were reconciled and various specialised sources were used to extract additional species information, i.e. -

Within the great diversity of pines in Mexico, Pinus culminicola Andresen et Beaman, P. jaliscana Perez de la Rosa, P. maximartinenzii Rzed., P. nelsonii Shaw, P. pinceana Gordon, and P. rzedowskii Madrigal et M. Caball. are six catalogued as threatened or endangered due to their restricted distribution and low population density. Therefore, they are of special interest for forest conservation purposes. In this paper, we aim to provide up-to-date information on the spatial distribution of these six pine species according to different historical registers coming from different herbaria distributed around the country by using spatial modeling. Therefore, we recovered historical observations of the natural distribution of each species and modelled suitable areas of distribution according to environmental requirements. Finally, we evaluated the distributions by contrasting changes of vegetation in the period 1991–2016. -
Producción De Semilla Y Potencial Biológico De Tres Especies De Pinus

Permite comparar el comportamiento de tres taxa de Pinus en los años 2013 y 2015. Se realizó la caracterización de sus conos a partir de sus dimensiones en ambos años, y se compararon los incrementos o decrementos en diámetro y longitud. Pinus engelmannii presentó un aumento en longitud de 17 mm y en diámetro de 19 mm; Pinus durangensis decreció 20 mm en longitud y aumentó 23 mm en diámetro. Pinus cooperi ganó 4 mm en longitud y 13 mm en diámetro. El tamaño del cono se relaciona con el potencial biológico y la producción de semilla (semillas desarrolladas, SD). En Pinus engelmannii el potencial biológico fue más alto en ambos años; Pinus durangensis y P. cooperi registraron un incremento de 2013 a 2015. Respecto a la producción de semillas (semillas desarrolladas, SD), no hubo diferencia significativa entre años Pinus engelmannii; Pinus cooperi y P. durangensis si se obtuvieron. La comparación de la producción de semilla en el género Pinus ayuda a conocer si existen diferencias significativas entre años de producción, áreas y especies, y así determinar que factores influyen en esa variación y como reducen la viabilidad y cantidad de semilla en los bosques. -
