Mammals and plants on three continents: ecological niche modeling of species distributions for studies of evolutionary ecology, climate change, and invasive species
Tuesday, October 5, 2010, 6:30 PM
Presented by Robert P. Anderson, Associate Professor, Department of Biology, City College of the City University of New York (CCNY/CUNY)

Abstract:
Coupled with a great increase in the online availability of species occurrence records and environmental data, recent theoretical and computational advances now allow ecological niche modeling of species geographic distributions using Geographic Information Systems (GIS). Such models hold wide application across ecology, evolutionary biology, biogeography, and conservation, including studies of the effects of climatic and other environmental changes. Although free, user-friendly software is available over the internet, production of realistic niche models requires substantial knowledge of the study species and of the principles of model evaluation. I present an overview of these developments, using examples from my research on mammals and plants. Specific study groups include purple loosestrife in the Great Plains, legumes in the Guiana Shield, rodents and tenrecs in Madagascar, and rodents in the sky islands of northern Venezuela.

 

Seed Banking in New York: A Biological Savings Account\
Wednesday, November 3, 2010, 6:30 PM
Presented by Tim Chambers and Heather Liljengren, NYC Department of Parks & Recreation’s Greenbelt Native Plant Center

Abstract:
Did you know that there is a global bank of seeds being saved around the world to protect plant species? The Greenbelt Native Plant Center, along with Brooklyn Botanic Garden, have contributed 75 native plant species from our region to the Millennium Seed Bank Project, an initiative led by the Royal Botanic Gardens, Kew, which has been called a Noah’s ark for Earth’s flora. The Native Plant Center and BBG are founding partners of the Seeds of Success program, which aims to preserve seed of the flora of the United States and develop native plant materials from regional and local seed resources. The Native Plant Center currently maintains its own seed bank and is working with BBG to develop a mid-Atlantic regional seed bank to help others conserve their local flora.

To stock seed banks, botanists collect samples from native wild populations. Each collection is processed, individually packaged, and deposited in the bank, similar to a giant walk-in cooler. These collections have the potential to survive storage for hundreds of years. The seeds can then be used to stem the effects of such conditions as habitat loss and fragmentation, climate change, and biological invasion, now and into the future.

 

The role of field work in modern systematics; planes, trains and automobiles (plus other modes of transportation) in search of neotropical Melastomataceae
Tuesday, December 7, 2010, 6:30 PM
Presented by Fabian Michelangeli, Assistant Curator, Institute of Systematic Botany, The New York Botanical Garden

Abstract:
Modern systematics relies on several tools not available only a few decades ago, such as DNA sequencing and powerful computing. Thus, many evolutionary biologists have focused their research in the laboratory, trying to take advantage of these developments in order to answer questions that we could not address in the past. During this talk I will show, using systematics work on the Melastomataceae (meadow beauties and princess flowers) as an example, how field work is still necessary to carry out modern systematics. Some unforeseen lines of research have developed from actual observations of the plants in the field, which has opened completely new lines of research in this group of plants.

Tiger nuts and velcro plants: a walk through the relationships, biogeography and remarkable diversity of sedges (family Cyperaceae)
Tuesday, April 5, 2011, 6:30 PM
Presented by Julian R. Starr, Associate Professor, Department of Biology, University of Ottawa, and Research Scientist, Canadian Museum of Nature

Abstract:
The Cyperaceae or sedge family is a truly remarkable group characterised by its exceptional diversity (ca. 5000 spp.), varied habitats (deserts to rain forests), unusual chromosomes (holocentric) and diverse biogeographical patterns. Distributed across every continent except Antarctica, sedges represent nearly 3% of the native vascular flora of North America, north of Mexico, and in some regions, such as the Arctic, they are the dominant component in terms of species diversity and biomass. In addition, approximately 10% of sedge species are of either direct (e.g., medicines, crops) or indirect (e.g., weeds) economic importance to humanity, and yet sedges are largely unknown to the general public, and they are frequently mistaken for other plants such as rushes or grasses, even by professionals. In this talk we will learn about the fascinating biology of the sedge family and how to recognise them in nature. In addition, we will learn about recent advances in our understanding of their relationships, evolution, and diversity through the application of new genetic techniques such as DNA sequencing and barcoding. Recent collecting trips to the Arctic, the Rocky Mountains, and the most southerly reaches of South America (Tierra del Fuego), will highlight the beginning of our research on the biogeography and taxonomy of arctic-alpine and bipolar species complexes including the discovery of hidden diversity in this poorly known, but remarkable family of plants.

 

Trouble in Paradise: Are We Losing Our Native Bees?
Wednesday, May 4, 2011 6:30 PM
Presented by Stephen Buchmann, entomologist, International Coordinator of The Pollinator Partnership and co-author of The Forgotten Pollinators
This lecture is presented in collaboration with NYC Wildflower Week (nycwildflowerweek.org)

Abstract:
Dr. Stephen Buchmann, co-author of “The Forgotten Pollinators,” twelve other books and more than 170 scientific publications, presents an illustrated talk showcasing North American native bee diversity, along with threats to bees and other pollinators. The amazing ways bees make a living, from carpenters to masons to social parasite free-loaders will be examined along with their fantastic mutualistic dances with flowering plants. Learn about flowers that produce resins, oils and perfumes besides ordinary pollen and nectar floral rewards. See the world’s smallest bee (under 2mm) from the Sonoran desert. Stephen will also update us on the current situation plaguing honey bees, Colony Collapse Disorder, and steps the Pollinator Partnership (www.pollinator.org) is taking to alleviate it and help beekeepers. Declines in several U.S. bumble bee species will be examined. Its not all doom and gloom, as he suggests simple things to do, steps we can all take in our backyards, gardens and schools to help native bees and other pollinating animals. You can become a bee rancher, a pollinator landlord! Several of Dr. Buchmann’s books may be available for purchase and signing after his talk.

Fellowship Available at Mohonk Preserve, Ulster County

October 22, 2010

Mohonk Preserve is once again pleased to announce our 2010-2011 fellowship opportunities under the Loewy-Mohonk Preserve Liaison Fellowship program.   Located in the northern Shawangunk Mountains of eastern New York State, the Mohonk Preserve protects nearly 7,000 acres of land. The condition of the Preserve’s forest have degraded due to more than 50 years of fire suppression,  white-tailed deer browsing impacts, and the increasing presence of invasive species.  The Mohonk Preserve is seeking to restore the viability of natural communities, native species and the ecological processes they depend on. Forest restoration at a landscape scale will require an integrated management approach to abate the multiple threats that have been identified. It will also depend on a shared vision of desired future conditions and commitment to implementation, monitoring and adaptive management.  Through the 2010-11 Loewy-Mohonk Preserve Liaison Fellowship, up to $10,000 will be awarded to a project (or projects) that will contribute to the understanding and conservation of this ecologically significant landscape.

The program guidelines and announcement flyer listing some of our highest priority subjects and information about the Daniel Smiley Research Center can be found on our website at http://www.mohonkpreserve.org/index.php?jobs-internship#loewy

Should you be interested in applying for a fellowship, please take a look at the guidelines at the link above or feel free to forward this information to others who may be interested.

Deadline for applications is November 30th 2010.

Our fellowship opportunities are made possible through funding from The Loewy Family Foundation, Inc.

Please contact Paul Huth, Director of Research, or John Thompson, Natural Resources Specialist at the Mohonk Preserve if you have questions or need further information.
