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. -

Larger, more comprehensive treatments and papers describing new taxa are treated in the first part of this Records [Bishop Museum Occasional Papers 48]. Foraminifera of Hawaii: Literature Survey THOMAS A. BURCH & BEATRICE L. BURCH (Research Associates in Zoology, Hawaii Biological Survey, Bishop Museum, 1525 Bernice Street, Honolulu, HI 96817, USA) The result of a compilation of a checklist of Foraminifera of the Hawaiian Islands is a list of 755 taxa reported in the literature below. The entire list is planned to be published as a Bishop Museum Technical Report. This list also includes other names that have been applied to Hawaiian foraminiferans. Loeblich & Tappan (1994) and Jones (1994) dis- agree about which names should be used; therefore, each is cross referenced to the other. Literature Cited Bagg, R.M., Jr. 1980.

The models are driven by the IPCC IS92a scenario of rising CO2 (Wigley et al. 1991), and by climate changes resulting from effective CO2 concen- trations corresponding to IS92a, simulated by the coupled ocean atmosphere model HadCM2-SUL. Simulations with changing CO2 alone show a widely distributed ter- restrial carbon sink of 1.4±3.8 Pg C y±1 during the 1990s, rising to 3.7±8.6 Pg C y±1 a cen- tury later. -

Los ecosistemas urbanos son aquellos defi nidos como ambientes dominados por el hombre. Con el proceso de urbanización, insectos y arácnidos silvestres aprovechan los nuevos microhábitats que las viviendas humanas ofrecen. Se revisaron arañas recolectadas dentro de 109 viviendas durante los años de 1985 a 1986, 1996 a 2001 y 2002 a 2003. Se cuantifi caron 1 196 organismos , los cuales se determinaron hasta especie. Se obtuvo una lista de 25 familias, 52 géneros y 63 especies de arañas sinantrópicas. Se utilizaron 3 índices (ocupación, densidad y estacionalidad) y un análisis de intervalos para sustentar la siguiente clasifi cación: accidentales (índice de densidad de 0-0.9), ocasionales (1-2.9), frecuentes (3.0-9.9) y comunes (10 en adelante). Se comparan las faunas de arañas sinantrópicas de 5 países del Nuevo Mundo. Palabras clave: sinantropismo, ecología, urbanización, microhábitats. Abstract. Urban ecology is a relatively new area of research, with urban ecosystems being defi ned as environments dominated by humans.

Araneae (Spider) Photos
Araneae (Spider) Photos Araneae (Spiders) About Information on: Spider Photos of Links to WWW Spiders Spiders of North America Relationships Spider Groups Spider Resources -- An Identification Manual About Spiders As in the other arachnid orders, appendage specialization is very important in the evolution of spiders. In spiders the five pairs of appendages of the prosoma (one of the two main body sections) that follow the chelicerae are the pedipalps followed by four pairs of walking legs. The pedipalps are modified to serve as mating organs by mature male spiders. These modifications are often very complicated and differences in their structure are important characteristics used by araneologists in the classification of spiders. Pedipalps in female spiders are structurally much simpler and are used for sensing, manipulating food and sometimes in locomotion. It is relatively easy to tell mature or nearly mature males from female spiders (at least in most groups) by looking at the pedipalps -- in females they look like functional but small legs while in males the ends tend to be enlarged, often greatly so. In young spiders these differences are not evident. There are also appendages on the opisthosoma (the rear body section, the one with no walking legs) the best known being the spinnerets. In the first spiders there were four pairs of spinnerets. Living spiders may have four e.g., (liphistiomorph spiders) or three pairs (e.g., mygalomorph and ecribellate araneomorphs) or three paris of spinnerets and a silk spinning plate called a cribellum (the earliest and many extant araneomorph spiders). Spinnerets' history as appendages is suggested in part by their being projections away from the opisthosoma and the fact that they may retain muscles for movement Much of the success of spiders traces directly to their extensive use of silk and poison. -

An Updated Infrageneric Classification of the North American Oaks
Article An Updated Infrageneric Classification of the North American Oaks (Quercus Subgenus Quercus): Review of the Contribution of Phylogenomic Data to Biogeography and Species Diversity Paul S. Manos 1,* and Andrew L. Hipp 2 1 Department of Biology, Duke University, 330 Bio Sci Bldg, Durham, NC 27708, USA 2 The Morton Arboretum, Center for Tree Science, 4100 Illinois 53, Lisle, IL 60532, USA; [email protected] * Correspondence: [email protected] Abstract: The oak flora of North America north of Mexico is both phylogenetically diverse and species-rich, including 92 species placed in five sections of subgenus Quercus, the oak clade centered on the Americas. Despite phylogenetic and taxonomic progress on the genus over the past 45 years, classification of species at the subsectional level remains unchanged since the early treatments by WL Trelease, AA Camus, and CH Muller. In recent work, we used a RAD-seq based phylogeny including 250 species sampled from throughout the Americas and Eurasia to reconstruct the timing and biogeography of the North American oak radiation. This work demonstrates that the North American oak flora comprises mostly regional species radiations with limited phylogenetic affinities to Mexican clades, and two sister group connections to Eurasia. Using this framework, we describe the regional patterns of oak diversity within North America and formally classify 62 species into nine major North American subsections within sections Lobatae (the red oaks) and Quercus (the Citation: Manos, P.S.; Hipp, A.L. An Quercus Updated Infrageneric Classification white oaks), the two largest sections of subgenus . We also distill emerging evolutionary and of the North American Oaks (Quercus biogeographic patterns based on the impact of phylogenomic data on the systematics of multiple Subgenus Quercus): Review of the species complexes and instances of hybridization. -
FY96 NCAR ASR Highlights
FY96 NCAR ASR Highlights 1996 ASR Highlights Highlights of NCAR's FY96 Achievements These are the most significant highlights from each NCAR division and program. Atmospheric Chemistry Division Highlights data missing Atmospheric Technology Division Highlights AVAPS/GPS Dropsonde System The development of the advanced Airborne Vertical Atmospheric Profiling System (AVAPS)/GPS Dropsonde System was close to completion at the end of FY 96. This work has been supported by NOAA and the Deutsche Forschungsanstalt fuer Luft- und Raumfahrt (DLR, Germany). AVAPS has now progressed to the point where all the NOAA data systems (two four-channel systems plus spares for the NOAA G-IV aircraft and two four-channel systems plus spares for the NOAA P-3 aircraft) have been delivered, and the initial flight testing has been completed. Both high-level (45,000-foot-altitude) and low-level (22,000-foot-altitude) drop tests have been completed, including intercomparison tests in which sondes were dropped from both the G-IV and the P-3s. Data taken by the AVAPS system on the G-IV and by a second system installed in a leased Lear 36 aircraft are expected to play a key role in the Fronts and Atlantic Storm Tracks Experiment (FASTEX), scheduled for early 1997. The DLR four-channel AVAPS system is currently being built and will be installed on the DLR Falcon aircraft in March 1997. NCAR has transferred the technology to the public sector by licensing a commercial firm (Vaisala, Inc.) to build future GPS sondes and data systems. This effort is led by Hal Cole and Terry Hock.
