Different Environmental Gradients Affect Different Measures of Snake Β-Diversity in the Amazon Rainforests
Different environmental gradients affect different measures of snake β-diversity in the Amazon rainforests Rafael de Fraga1,2,3, Miquéias Ferrão1, Adam J. Stow2, William E. Magnusson4 and Albertina P. Lima4 1 Programa de Pós-Graduação em Ecologia, Instituto Nacional de Pesquisas da Amazônia, Manaus, Amazonas, Brazil 2 Department of Biological Sciences, Macquarie University, Sydney, NSW, Australia 3 Programa de Pós-graduação em Sociedade, Natureza e Desenvolvimento, Universidade Federal do Oeste do Pará, Santarém, Pará, Brazil 4 Coordenação de Biodiversidade, Instituto Nacional de Pesquisas da Amazônia, Manaus, Amazonas, Brazil ABSTRACT Mechanisms generating and maintaining biodiversity at regional scales may be evaluated by quantifying β-diversity along environmental gradients. Differences in assemblages result in biotic complementarities and redundancies among sites, which may be quantified through multi-dimensional approaches incorporating taxonomic β-diversity (TBD), functional β-diversity (FBD) and phylogenetic β-diversity (PBD). Here we test the hypothesis that snake TBD, FBD and PBD are influenced by environmental gradients, independently of geographic distance. The gradients tested are expected to affect snake assemblages indirectly, such as clay content in the soil determining primary production and height above the nearest drainage determining prey availability, or directly, such as percentage of tree cover determining availability of resting and nesting sites, and climate (temperature and precipitation) causing physiological filtering. We sampled snakes in 21 sampling plots, each covering five km2, distributed over 880 km in the central-southern Amazon Basin. We used dissimilarities between sampling sites to quantify TBD, FBD and PBD, Submitted 30 April 2018 which were response variables in multiple-linear-regression and redundancy analysis Accepted 23 August 2018 Published 24 September 2018 models. -

Juvenile Resilience and Adult Longevity Explain Residual Populations of the Andean Wax Palm Ceroxylon Quindiuense After Deforestation
Juvenile Resilience and Adult Longevity Explain Residual Populations of the Andean Wax Palm Ceroxylon quindiuense after Deforestation María José Sanín1*, Fabien Anthelme2,3, Jean-Christophe Pintaud3, Gloria Galeano1, Rodrigo Bernal1 1 Instituto de Ciencias Naturales, Universidad Nacional de Colombia, Bogotá, Distrito Capital, Colombia, 2 Botanique et Bioinformatique de l’Architecture des Plantes, Recherche Agronomique pour Le Développement, Institut de recherche pour le développement, Montpellier, Hérault, France, 3 Botanique et Bioinformatique de l’Architecture des Plantes and Diversité Adaptation et Développement des plantes, Institut de recherche pour le développement, Montpellier, Hérault, France Abstract Wax palms are an important element of the cloud forests in the tropical Andes. Despite heavy deforestation, the density of adults seems to be similar in deforested pastures as in forests. We aimed to infer the mechanisms responsible for this apparent resilience in pastures and we tested two hypotheses to explain it: 1) adult palms survived in pastures because they were spared from logging, and 2) adults occurred in pastures through the resilience of large juvenile rosettes, which survived through subterranean meristems and later developed into adults. For this purpose, we characterized the demographic structure of C. quindiuense in a total of 122 plots of 400 m2 in forests and pastures at two sites with contrasted land use histories in Colombia and Peru. Additionally, we implemented growth models that allowed us to estimate the age of individuals at four sites. These data were combined with information collected from local land managers in order to complete our knowledge on the land use history at each site. At two sites, the presence of old individuals up to 169 years and a wide age range evidenced that, at least, a portion of current adults in pastures were spared from logging at the time of deforestation. -

Processes of urbanization, expansion of the agricultural and livestock area, among 19 others, have increased its level of threat. Protecting this palm from extinction is important at an ecological level, given 20 its function as a key species in Andean ecosystems. This work evaluated the diversity and population genetic structure 21 of the wax palm from Quindío in five populations of the Colombian coffee region eco-region (Andean zone) by using 22 ten microsatellite molecular markers. -
New Tradition for the Catholic Church Saves Palms and Parrots
New Tradition for the Catholic Church saves Palms and Parrots By PAUL SALAMAN Wax Palms (Ceroxylon quindiuense) - the world's tallest palm and an endangered species - are massacred each Easter to provide palm fronds for the Palm Sunday processions and used to adorn churches throughout the Colombian Andes (See Paul Salaman. PsittaScene Feb 2002, No 50). Unfortunately, the Critically Endangered Yellow-eared Parrot (Ognorhynchus icterotis) is dependent on the wax palm for nesting and roosting, so the parrot’s survival is inextricably linked to the plight of the wax palm. So our euphoria at discovering a population of Yellow-eared Parrots in western Colombia last year was short-lived as our worst nightmares were realised when thousands of people waved wax palm fronds to church on a glorious Palm Sunday morning in 2001. As there are less than a thousand wax palms sites uncovered revealing the total population at wax palm frond could be found in the procession scattered across the parrot’s range in the Western a staggering 277 individuals - two thirds of the of 5,000 people! A triumph for the wax palm, for Andes, their survival and that of the palm global population! Clearly, much was at stake on the Yellow-eared Parrot and for the Catholic appeared depressingly remote. The Fundación Palm Sunday in protecting the Yellow-eared Church, plus 600 new palm recruits in the town ProAves - Colombia team, that operates Project Parrots’ stronghold. from the seedlings and many more planted in the Ognorhynchus - knew we had to act quickly and countryside. Palm Sunday this year was a fine effectively to avoid the impending catastrophe Yet, as we approached Palm Sunday in March day to celebrate! 2002, one final daunting obstacle seemed for both species. -

ABSTRACT Introduction: Understanding the phenology of plant populations is vital for their conservation and management. We studied the vegetative and reproductive phenology of the endangered palm Ceroxylon quindiuense along an altitudinal gradient in the Central Cordillera of Colombia. Objective: We describe the leaf production rate, and flowering and fruiting cycles, and calculate food offer for the fauna, as a tool for the proper management of the palm. Methods: At each sampling site (2 400, 2 600, 2 800, 3 000 m.a.s.l.), we marked 40 adult individuals (20 pistillate, 20 staminate), which we followed bimonthly for 24 months. -

We propose a method for seed shape quantification based on the comparison of the bi-dimensional images of the seeds with geometric figures. J index is the percent of similarity of a seed image with a figure taken as a model. Models in shape quantification include geometrical figures (circle, ellipse, oval ::: ) and their derivatives, as well as other figures obtained as geometric representations of algebraic equations. The analysis is based on three sources: Published work, images available on the Internet, and seeds collected or stored in our collections. Some of the models here described are applied for the first time in seed morphology, like the superellipses, a group of bidimensional figures that represent well seed shape in species of the Calamoideae and Phoenix canariensis Hort. ex Chabaud.
