Received: 10 January 2019; Accepted: 22 February 2019; Published: 26 February 2019 Abstract: The lotus (Nelumbo Adans.) is a perennial aquatic plant with important value in horticulture, medicine, food, religion, and culture. It is rich in germplasm and more than 2000 cultivars have been cultivated through hybridization and natural selection. Microsporogenesis and male gametogenesis in the anther are important for hybridization in flowering plants. However, little is known about the cytological events, especially related to the stamen, during the reproduction of the lotus. -

Wild Patagonia & Central Chile
WILD PATAGONIA & CENTRAL CHILE: PUMAS, PENGUINS, CONDORS & MORE! NOVEMBER 1–18, 2019 Pumas simply rock! This year we enjoyed 9 different cats! Observing the antics of lovely Amber here and her impressive family of four cubs was certainly the highlight in Torres del Paine National Park — Photo: Andrew Whittaker LEADERS: ANDREW WHITTAKER & FERNANDO DIAZ LIST COMPILED BY: ANDREW WHITTAKER VICTOR EMANUEL NATURE TOURS, INC. 2525 WALLINGWOOD DRIVE, SUITE 1003 AUSTIN, TEXAS 78746 WWW.VENTBIRD.COM Sensational, phenomenal, outstanding Chile—no superlatives can ever adequately describe the amazing wildlife spectacles we enjoyed on this year’s tour to this breathtaking and friendly country! Stupendous world-class scenery abounded with a non-stop array of exciting and easy birding, fantastic endemics, and super mega Patagonian specialties. Also, as I promised from day one, everyone fell in love with Chile’s incredible array of large and colorful tapaculos; we enjoyed stellar views of all of the country’s 8 known species. Always enigmatic and confiding, the cute Chucao Tapaculo is in the Top 5 — Photo: Andrew Whittaker However, the icing on the cake of our tour was not birds but our simply amazing Puma encounters. Yet again we had another series of truly fabulous moments, even beating our previous record of 8 Pumas on the last day when I encountered a further 2 young Pumas on our way out of the park, making it an incredible 9 different Pumas! Our Puma sightings take some beating, as they have stood for the last three years at 6, 7, and 8. For sure none of us will ever forget the magical 45 minutes spent observing Amber meeting up with her four 1- year-old cubs as they joyfully greeted her return. -
Phylogeny and Classification of the Melastomataceae and Memecylaceae
Nord. J. Bot. - Section of tropical taxonomy Phylogeny and classification of the Melastomataceae and Memecy laceae Susanne S. Renner Renner, S. S. 1993. Phylogeny and classification of the Melastomataceae and Memecy- laceae. - Nord. J. Bot. 13: 519-540. Copenhagen. ISSN 0107-055X. A systematic analysis of the Melastomataceae, a pantropical family of about 4200- 4500 species in c. 166 genera, and their traditional allies, the Memecylaceae, with c. 430 species in six genera, suggests a phylogeny in which there are two major lineages in the Melastomataceae and a clearly distinct Memecylaceae. Melastomataceae have close affinities with Crypteroniaceae and Lythraceae, while Memecylaceae seem closer to Myrtaceae, all of which were considered as possible outgroups, but sister group relationships in this plexus could not be resolved. Based on an analysis of all morph- ological and anatomical characters useful for higher level grouping in the Melastoma- taceae and Memecylaceae a cladistic analysis of the evolutionary relationships of the tribes of the Melastomataceae was performed, employing part of the ingroup as outgroup. Using 7 of the 21 characters scored for all genera, the maximum parsimony program PAUP in an exhaustive search found four 8-step trees with a consistency index of 0.86. Because of the limited number of characters used and the uncertain monophyly of some of the tribes, however, all presented phylogenetic hypotheses are weak. A synapomorphy of the Memecylaceae is the presence of a dorsal terpenoid-producing connective gland, a synapomorphy of the Melastomataceae is the perfectly acrodro- mous leaf venation. Within the Melastomataceae, a basal monophyletic group consists of the Kibessioideae (Prernandra) characterized by fiber tracheids, radially and axially included phloem, and median-parietal placentation (placentas along the mid-veins of the locule walls). -
La Brea and Beyond: the Paleontology of Asphalt-Preserved Biotas
La Brea and Beyond: The Paleontology of Asphalt-Preserved Biotas Edited by John M. Harris Natural History Museum of Los Angeles County Science Series 42 September 15, 2015 Cover Illustration: Pit 91 in 1915 An asphaltic bone mass in Pit 91 was discovered and exposed by the Los Angeles County Museum of History, Science and Art in the summer of 1915. The Los Angeles County Museum of Natural History resumed excavation at this site in 1969. Retrieval of the “microfossils” from the asphaltic matrix has yielded a wealth of insect, mollusk, and plant remains, more than doubling the number of species recovered by earlier excavations. Today, the current excavation site is 900 square feet in extent, yielding fossils that range in age from about 15,000 to about 42,000 radiocarbon years.

On the 21 April 2012 a juvenile T. rumicivorus was photographed and sound-recorded by birdwatchers on the beach at Ubatumirim in the municipality of Ubatuba, on the northern São Paulo state coast. This is the first documented record of any seedsnipe (Thinocoridae) for Brazil. Its behaviour and the circumstances and potential drivers of its vagration are discussed.

On both occasions a pair of specimens with winter plumage was observed. The Hudsonian Godwit Limosa haemastica (Linnaeus tide and each time birds were feeding in the intertidal 1758) is a neartic migratory species that breeds in Alaska zone. These individuals showed the winter plumage and Canada during summer and spends its non-breeding pattern: dark reddish chest and white ventral region, black period in the southernmost regions of South America primaries and tail feathers, a long upturned bill pink at during the boreal winter. -
Diversidad De Plantas Y Vegetación Del Páramo Andino
Plant diversity and vegetation of the Andean Páramo Diversidad de plantas y vegetación del Páramo Andino By Gwendolyn Peyre A thesis submitted for the degree of Doctor from the University of Barcelona and Aarhus University University of Barcelona, Faculty of Biology, PhD Program Biodiversity Aarhus University, Institute of Bioscience, PhD Program Bioscience Supervisors: Dr. Xavier Font, Dr. Henrik Balslev Tutor: Dr. Xavier Font March, 2015 Aux peuples andins Summary The páramo is a high mountain ecosystem that includes all natural habitats located between the montane treeline and the permanent snowline in the humid northern Andes. Given its recent origin and continental insularity among tropical lowlands, the páramo evolved as a biodiversity hotspot, with a vascular flora of more than 3400 species and high endemism. Moreover, the páramo provides many ecosystem services for human populations, essentially water supply and carbon storage. Anthropogenic activities, mostly agriculture and burning- grazing practices, as well as climate change are major threats for the páramo’s integrity. Consequently, further scientific research and conservation strategies must be oriented towards this unique region. Botanical and ecological knowledge on the páramo is extensive but geographically heterogeneous. Moreover, most research studies and management strategies are carried out at local to national scale and given the vast extension of the páramo, regional studies are also needed. The principal limitation for regional páramo studies is the lack of a substantial source of good quality botanical data covering the entire region and freely accessible. To meet the needs for a regional data source, we created VegPáramo, a floristic and vegetation database containing 3000 vegetation plots sampled with the phytosociological method throughout the páramo region and proceeding from the existing literature and our fieldwork (Chapter 1). -
