Nota técnica: Una nueva localidad para la distribución geográfica de 189 Batrachemys heliostemma (Reptilia, Chelidae) en la Amazonía peruana INTRODUCCIÓN AL VOLUMEN 14 DE FOLIA AMAZÓNICA En este volumen de Folia Amazónica se presentan varios resultados realizados en el marco del proyecto Diversidad Biológica de la Amazonía Peruana, Perú - Finlandia (BIODAMAZ), en su primera fase. Dicho proyecto de cooperación técnica tiene su origen en un convenio entre los gobiernos del Perú y de Finlandia cuya ejecución tuvo lugar de 1999 al 2002. A partir del año 2003 se ejecutará la segunda fase del proyecto BIODAMAZ (2003 – 2007). El objetivo general de la primera fase del proyecto fue la conservación y uso sostenible de la diversidad biológica amazónica, y su propósito fue brindar instrumentos de gestión y metodologías de investigación para el manejo sostenible de la diversidad biológica de la Amazonía peruana. A través de estas acciones el proyecto aspiró a asistir el desarrollo socioeconómico sostenible de esta importante región. La contraparte nacional del proyecto BIODAMAZ es el Instituto de Investigaciones de la Amazonía Peruana (IIAP). La contraparte finlandesa en la ejecución del proyecto es un consorcio formado por la empresa finlandesa de consultorías ambientales, Biota BD Oy, y la Universidad de Turku. La Universidad Nacional de la Amazonía Peruana (UNAP) ha colaborado en numerosas formas durante la ejecución del proyecto. El artículo por H. Tello y S.-K. Juvonen describe los antecedentes y los alcances del proyecto BIODAMAZ, así como expone la perspectiva general del contenido del proyecto. Los otros artículos resumen la información generada en el proyecto sobre flora y fauna amazónica, incluyendo una evaluación de plantas ecológica y económicamente importantes del Jardín Botánico - Arboretum El Huayo de la UNAP, y los resultados de estudios obtenidos en la Zona Reservada Allpahuayo – Mishana, y en otros lugares de la selva baja de la Amazonía peruana. Se describe un sistema de información generada para difundirla al público general y especializado, y una metodología para elaborar un mosaico de imágenes de satélite a efecto de apoyar los procesos de planificación del uso de la tierra. A través de generación de información novedosa sobre los ecosistemas amazónicos es posible llegar a una planificación más detallada y actualizada del uso de la tierra, que favorezca un vínculo fuerte con la actual realidad amazónica: natural y humana. La generación del conocimiento sobre las condiciones naturales beneficia tanto la conservación de los recursos valiosos de la naturaleza como su uso sostenible. Sin conocimiento el manejo de dichos recursos es prácticamente imposible, por lo que queremos contribuir dando de este modo una importancia grande a la investigación científica que es capaz de generar esta información esencial para el desarrollo sostenible de la Amazonía peruana.

Se ha constatado la presencia de 56 especies entre aves, mamíferos y reptiles, en 371.05 km de recorrido. Entre las especies más importantes está el coto (Alouatta seniculus), mono negro (Cebus apella), choro (Lagothrix lagothricha), sachavaca (Tapirus terrestris), otorongo (Panthera onca), huamburushi (huamburushu) (Leopardus wiedii) y tigrillo (Leopardus pardalis). La perdiz yanayuto (Cripturellus cinereus) es la más abundante entre las aves de caza, seguida de la perdiz grande (Tinamus guttatus) y la pucacunga (Penelope jacquacu). Entre los reptiles se incluye el quelonio Batrachemys heliostemma, como nuevo registro en la lista de especies de la ZRAM. Se puede observar que la parte más occidental de la ZRAM presenta un mejor estado de conservación, probablemente debido a una menor utilización de recursos de fauna. Palabras clave: Animales de caza, evaluación, Zona Reservada Allpahuayo-Mishana. ABSTRACT The result of the transect inventories of game animals in eight areas within the Allpahuayo-Mishana Reserved Zone (ZRAM) are presented in this article. In total, 56 species of game birds, mammals and reptiles were observed in the 371.05 kilometers under study. Among the most important species are: howler monkey (Alouatta seniculus), black capuchin monkey (Cebus apella), woolly monkey (Lagothrix lagothricha), tapir (Tapirus terrestris), jaguar (Panthera onca), tree ocelot (Leopardus wiedii) and ocelot (Leopardus pardalis). The cinereous tinamou (Cripturellus cinereus) is the most abundant game bird species, followed by the great tinamou (Tinamus guttatus) and Spix’s guan (Penelope jacquacu). Among the reptiles reported, the turtle Batrachemys heliostemma was registered for the first time in the ZRAM. According to this study, the western

Hammer (editor) Biosphere Expeditions £10 / €15 where sold Abstract In 2003 Biosphere Expeditions completed a second successful year of biodiversity investigations at the Piedras Biodiversity Station along the River Las Piedras in the Per Amazon. This year the expedition ran between 15 June and 25 July 2003 and concentrated on four projects. The herpetology project was the first of its kind for the Piedras river system and in just four weeks the expedition collected and identified 71 species of frog, toad and reptile, a considerable number for such a short period of time. Data collection continued on the mammal transects and at the macaw colpa. The mammal transect investigations collected data on animal populations and compared populations in a hunted versus a non-hunted area. At the macaw colpa the team continued to investigate the impacts of boat traffic on parrot feeding behaviour and looked at species composition and numbers. A further study was carried out at a mammal colpa. Using combined print traps and a remote sensor video camera 14 species of bird and animal were recorded feeding at the colpa. En 2003 Biosphere Expeditions completo un segundo año exitoso de investigación en el Rió Las Piedras.

First, recent explorations in the Guayana Highland region of northern South America have amassed excellent collections in this interesting monocotyledonous family. The family is restricted to South America with the exception of a monotypic genus in western tropical Africa (Maguire et al., 1958). Although there is no reason to believe that all new species in the family have been described, the remarkable collections of material certainly do furnish an extensive basis for pollen study which has not been available previ­ ously. Of great significance in this regard are the collections of Maguire and his associates at the New York Botanical Garden. Many of these collections included liquid-preserved portions. A second reason for presentation of pollen studies is the excellent condition in which pollen-bearing material of many species was preserved. Because the delicate nature of pollen grains of Rapateaceae, as described below, makes preparation of pollen-grain slides from dried material often unsatisfactory, liquid-preserved material is especially im­ portant.

This taxon is remarkable for Rapatea in its small stature (15–30 cm tall) and leaves, and it is only the second species with white petals in a genus that otherwise has only yellow petals. It is most closely R. spruceana, with the base of the leaf blade gradually tapering from the intergrading into the petiole, and the bractlet of the spikelet and sepal shape. However, this new species differs from R. spruceana in its shorter size, sparse verrucose on the lower surface, the length of the attenuate portion of the involucral bracts, and the shape and color of the petals. It also has similarities to R. longipes and R. modesta in its ventricose sheath-leaf, inflorescence shape, and bractlets equal in length. A previously described species from Colombia is restablished (i.e., R. modesta), and one variety is elevated to the rank of species (i.e., R.

We also summarized data on lizard faunas for nine other well-studied areas in Amazonia to make pairwise comparisons among sites. The Biogeographic Similarity Coefficient for each pair of sites was calculated and plotted against the geographic distance between the sites. A Parsimony Analysis of Endemicity was performed comparing all sites. A total of 114 species has been recorded in the four studied sites, of which 45 are lizards, three amphisbaenians, and 66 snakes. The two sites between the Xingu and Madeira rivers were the poorest in number of species, those in western Amazonia, between the Madeira and Juruá Rivers, were the richest. Biogeographic analyses corroborated the existence of a well-defined separation between a western and an eastern lizard fauna. The western fauna contains two groups, which occupy respectively the areas of endemism known as Napo (west) and Inambari (southwest). Relationships among these western localities varied, except between the two northernmost localities, Iquitos and Santa Cecilia, which grouped together in all five area cladograms obtained. No variation existed in the area cladogram between eastern Amazonia sites. The easternmost localities grouped with Guianan localities, and they all grouped with localities more to the west, south of the Amazon River.

In this chapter, we attempt to describe the major types of vegetation cover in this vast region as they occurred in pre- Columbian times and outline the conditions that support them. Examining the large-scale phytogeographic regions characterized by each major cover type (see Fig. I), we provide basic information on geology, geological history, topography, and climate; describe variants of physiognomy (vegetation structure) and geography; discuss transitions; and examine some floristic patterns and affinities within and among these regions.

The easternmost populations of the genus are poorly studied and represented in collections. Herein we describe Stenocercus quinarius sp. n. from northwestern Minas Gerais and western Bahia states, and Stenocercus squarrosus sp. n. from the southern portion of the state of Piauí, two previously poorly sampled areas in central and northeastern Brazil. The two new species seem closely related to Stenocercus dumerilii and Stenocercus tricristatus, but are easily diagnosed from all Stenocercus and from each other based on morphometric and meristic characters. The distribution patterns and possible phylogenetic affinities of the eastermost, pyramidal headed Stenocercus group are discussed, along with an overview of distribution patterns

  • Nuclear Genes, Matk and the Phylogeny of the Poales
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2018 Nuclear genes, matK and the phylogeny of the Poales Hochbach, Anne ; Linder, H Peter ; Röser, Martin Abstract: Phylogenetic relationships within the monocot order Poales have been well studied, but sev- eral unrelated questions remain. These include the relationships among the basal families in the order, family delimitations within the restiid clade, and the search for nuclear single-copy gene loci to test the relationships based on chloroplast loci. To this end two nuclear loci (PhyB, Topo6) were explored both at the ordinal level, and within the Bromeliaceae and the restiid clade. First, a plastid reference tree was inferred based on matK, using 140 taxa covering all APG IV families of Poales, and analyzed using parsimony, maximum likelihood and Bayesian methods. The trees inferred from matK closely approach the published phylogeny based on whole-plastome sequencing. Of the two nuclear loci, Topo6 supported a congruent, but much less resolved phylogeny. By contrast, PhyB indicated different phylo- genetic relationships, with, inter alia, Mayacaceae and Typhaceae sister to Poaceae, and Flagellariaceae in a basally branching position within the Poales. Within the restiid clade the differences between the three markers appear less serious. The Anarthria clade is first diverging in all analyses, followed by Restionoideae, Sporadanthoideae, Centrolepidoideae and Leptocarpoideae in the matK and Topo6 data, but in the PhyB data Centrolepidoideae diverges next, followed by a paraphyletic Restionoideae with a clade consisting of the monophyletic Sporadanthoideae and Leptocarpoideae nested within them. The Bromeliaceae phylogeny obtained from Topo6 is insufficiently sampled to make reliable statements, but indicates a good starting point for further investigations.

Rapateaceae (16 genera, ;100 species) is largely restricted to the tepuis and sandplains of the Guayana Shield in northern South America, with Maschalocephalus endemic to West Africa. The family has undergone extensive radiation in ¯ower form, leaf shape, habit, and habitat. To analyze the evolution of these distributions and traits, we derived a molecular phylogeny for representatives of 14 genera, based on sequence variation in the chloroplast-encoded ndhF gene. The lowland subfamily Rapateoideae is paraphyletic and includes the largely montane subfamily Saxo- fridericioideae as a monophyletic subset. Overall, the morphological/anatomical data differ signi®cantly from ndhF sequences in phylogenetic structure, but show a high degree of concordance with the molecular tree in three of four tribes. Branch lengths are consistent with the operation of a molecular clock. Maschalocephalus diverges only slightly from other Monotremae: it is the product of relatively recent, long-distance dispersal, not continental driftÐonly its habitat atop rifted, nutrient-poor sandstones is vicariant. The family appears to have originated approximately 65 Mya in inundated lowlands of the Guayana Shield, followed by: (1) wide geographic spread of lowland taxa along riverine corridors; (2) colonization of Amazonian white-sand savannas in the western Shield; (3) invasion of tepui habitats with frequent speciation, evolution of narrow endemism, and origin of hummingbird pollination in the western Shield; and (4) reinvasion of lowland white-sand savannas.
