Morpho-species were not pooled based on 14morphological traits such as size, but they were distinguished at the smallest possible level 15without taxonomic determination and assigned a species code. Flower visitors were recorded as 16pollinators when they touched the sexual parts of flowers. Sampling of interactions was 17conducted by the same three observers throughout the 8-month flowering season and sampling 18was standardized between observers fortnightly. We used equal observation periods for all plant 19species to reduce sampling bias and to collect data on interaction frequency independent of size 20constraints and flower abundance (Ollerton and Cranmer 2002). 21 To assess the effect of sampling on network dissimilarities we conducted a rarefaction 22analysis (Hurlbert 1971, Heck et al. 1975). We calculated Bray-Curtis dissimilarities (see Section 23D below for a detailed description on dissimilarity matrices) between rarefied interaction 24matrices sampled at four different proportions (0.8, 0.6, 0.4 and 0.2) and compared the resulting 25mean ± 95% CI dissimilarities of the rarefied matrices to the dissimilarity between the original 26matrices. -

Vallee De Mai Nature Reserve Seychelles
VALLEE DE MAI NATURE RESERVE SEYCHELLES The scenically superlative palm forest of the Vallée de Mai is a living museum of a flora that developed before the evolution of more advanced plant families. It also supports one of the three main areas of coco-de-mer forest still remaining, a tree which has the largest of all plant seeds. The valley is also the only place where all six palm species endemic to the Seychelles are found together. The valley’s flora and fauna is rich with many endemic and several threatened species. COUNTRY Seychelles NAME Vallée de Mai Nature Reserve NATURAL WORLD HERITAGE SITE 1983: Inscribed on the World Heritage List under Natural Criteria vii, viii, ix and x. STATEMENT OF OUTSTANDING UNIVERSAL VALUE The UNESCO World Heritage Committee issued the following Statement of Outstanding Universal Value at the time of inscription Brief Synthesis Located on the granitic island of Praslin, the Vallée de Mai is a 19.5 ha area of palm forest which remains largely unchanged since prehistoric times. Dominating the landscape is the world's largest population of endemic coco-de- mer, a flagship species of global significance as the bearer of the largest seed in the plant kingdom. The forest is also home to five other endemic palms and many endemic fauna species. The property is a scenically attractive area with a distinctive natural beauty. Criterion (vii): The property contains a scenic mature palm forest. The natural formations of the palm forests are of aesthetic appeal with dappled sunlight and a spectrum of green, red and brown palm fronds. -
Seychelles Birding Trip Report
Seychelles birding trip report From December 26 (2008) to January 6 (2009) we spend our Christmas holidays on the Seychelles. Curiosity was the main driving force to visit this archipelago in the Indian ocean. Our goals were to see various islands, relax on the wonderful beaches, enjoy the local cuisine, snorkel the coral reefs, and last but not least do some birdwatching. We tried to see and photograph as many as possible endemics and tropical sea birds. December or January is definitely not the best time to visit the Seychelles because it’s the rainy season, and it’s outside the breeding season, making it hard to see some bird species or good numbers. Indeed we had a few days with a lot of rain and other days with very cloudy skies and wind. About half of the time we had marvelous sunny beach weather. Day time temperature usually was around 30°C. With regard to birding the preparation consisted of reading a number of trip reports from internet (see: www.travellingbirder.com) and the ‘Birds of the Seychelles’ by Skerrett et al. (2001). To see all endemics of the northern island of the Seychelles (the so-called granitic group) at least 4 islands need to be visit: Mahe, Praslin, La Digue, and Cousin. The first three island can be visited at any time. Tourist day trips to Cousin are usually organized on Tuesdays and Fridays and departure from Praslin, but as it turned out not on January 2, the day we were planning to go there. A fisherman was willing to take us to Cousin on another date in his small boat for 175 Euro. -

Development of the Tectum in Gymnophiones, with Comparison to Other Amphibians
JOURNAL OF MORPHOLOGY 236:233–246 (1998) Development of the Tectum in Gymnophiones, With Comparison to Other Amphibians ANDREA SCHMIDT1 AND MARVALEE H. WAKE2* 1University of Bremen, Brain Research Institute, 28334 Bremen, Germany 2Department of Integrative Biology and Museum of Vertebrate Zoology, University of California, Berkeley, California 94720-3140 ABSTRACT Tectal development in a number of caecilian (Gymnophiona: Amphibia) species was examined and compared with that in frogs and salamanders. The caecilian optic tectum develops along the same rostrocau- dal and lateromedial gradients as those of frogs and salamanders. However, differences exist in the time course of development. Our data suggest that, as in salamanders, simplification of morphological complexity in caecilians is due to a retardation or loss of late developmental stages. Differences in the time course of development (heterochrony) among different caecilian species are correlated with phylogenetic history as well as with variation in life histories. The most pronounced differences in development occur between the directly developing Hypogeophis rostratus and all other species examined. In this species, the increase in the degree of morphological complexity is greatly accelerated. J. Morphol. 236:233–246, 1998. 1998 Wiley-Liss, Inc.

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. -
1 Ornamental Palms
1 Ornamental Palms: Biology and Horticulture T.K. Broschat and M.L. Elliott Fort Lauderdale Research and Education Center University of Florida, Davie, FL 33314, USA D.R. Hodel University of California Cooperative Extension Alhambra, CA 91801, USA ABSTRACT Ornamental palms are important components of tropical, subtropical, and even warm temperate climate landscapes. In colder climates, they are important interiorscape plants and are often a focal point in malls, businesses, and other public areas. As arborescent monocots, palms have a unique morphology and this greatly influences their cultural requirements. Ornamental palms are over- whelmingly seed propagated, with seeds of most species germinating slowly and being intolerant of prolonged storage or cold temperatures. They generally do not have dormancy requirements, but do require high temperatures (30–35°C) for optimum germination. Palms are usually grown in containers prior to trans- planting into a field nursery or landscape. Because of their adventitious root system, large field-grown specimen palms can easily be transplanted. In the landscape, palm health and quality are greatly affected by nutritional deficien- cies, which can reduce their aesthetic value, growth rate, or even cause death. Palm life canCOPYRIGHTED also be shortened by a number of MATERIAL diseases or insect pests, some of which are lethal, have no controls, or have wide host ranges. With the increasing use of palms in the landscape, pathogens and insect pests have moved with the Horticultural Reviews, Volume 42, First Edition. Edited by Jules Janick. 2014 Wiley-Blackwell.
