GRANIVORES AND RESTORATION: IMPLICATIONS OF INVASION AND CONSIDERATIONS OF CONTEXT-DEPENDENT SEED REMOVAL By Steven M.

Ostoja, Doctor of Philosophy Utah State University, 2008 Major Professor: Eugene W. Schupp Department: Wildland Resources Granivores are important components of sagebrush communities in western North America. These same regions are being altered by the invasion of the exotic annual Bromus tectorum (cheatgrass) that alters physical and biological dynamics in ways that appear to promote its persistence. This research directly relates to the restoration of B. tectorum-dominated systems in two inter-related ways. First, because these landscapes have large quantities of seeds applied during restoration, it is important to determine the major granivore communities in intact sagebrush communities and in nearby cheatgrass- dominated communities. Second, it is important to develop an understanding of patterns of seed harvest by granivores. In addition to the data chapters there are two review chapters; Chapter 1 highlights factors contributing to seed removal and Chapter 7 provides ecologically based techniques that could minimize the negative consequences of granivores during ecological restoration. Common groups of ants showed increased abundances; uncommon species and functional groups were generally negatively impacted by cheatgrass (Chapter 2). Conversely, rodents were negatively impacted by iii conversion to cheatgrass (Chapter 4). Ant seed removal was highly context-dependent (Chapter 3), depending on the background vegetation (large-scale among-patch effects), foraging distance from the nest mound (small-scale among-patch effects), and the presence of other seed species in mixture (within-patch effects). In addition, cheatgrass provided associational resistance to native seeds in mixture, meaning the presence of cheatgrass increased native seed survival. In Chapter 5 a novel statistical technique in the ecological sciences showed that rodents have marked preferences for some seeds over others and that more seeds were removed in sagebrush compared to cheatgrass- dominated sites, although associational effects among seed mixtures were not detected. In Chapter 6 we show that the amount of seed harvested depended on both intraspecific and interspecific seed density. B. tectorum seeds had associational susceptibility (increased harvest) in the presence of native seeds. Although the reciprocal effect may occur, we did not find statistical support for it. These sets of studies are not only of basic ecological interests, but are also important for developing management strategies for restoration of these degraded lands. (216 pages) iv ACKNOWLEDGMENTS The decision to pursue a doctoral degree was not difficult, nor was the choice of major or focus of research. However, I knew all too well the importance of a suitable match between the student and the advisor. After meeting my advisor, Eugene W. Schupp, I knew within hours that he would be an ideal match for me. I was correct. Yet during the past five years as his student I have come to realize and fully appreciate what an excellent mentor, advisor, professional, and ecologist Dr. Schupp is. He had always maintained the perfect balance of fairness while being quite firm, negotiating constructive criticism with kindness, and knowing when to let up and when to hold steady on the reins of my sometimes over zealous ecological curiosity. Many of his lessons I did not understand at the time, but trusted his intentions and direction only to learn later the value of his teaching. I am very grateful to Geno for all that he has shared and taught and hope someday I can share a fraction of his lessons with others keen to pursue this scientific ambition. In addition to the edification from my advisor, I am very grateful to my committee, Karen Beard, Chris Call, James MacMahon, and Tom Monaco. Their patience, conversations, and encouragements were invaluable assets in the production of the research contained herein. In that group I also include Dr. Bill Longland, who was very helpful with numerous questions and discussions and who has been a wonderful collaborator in side projects with Geno and me. I thank many professors in both the College of Natural Resources and/or the Ecology Center for helpful and encouraging conversations and advice, including Helga Van Miegroet, James Long, Mike Wolf, John Malechek, and Johan Du Toit among many others. I also wish to thank David Pyke (USGS-OSU), Paul Doescher (OSU), Bob v Nowak (UNR), Jeanne Chambers (USFS-UNR), and Stephen Vander Wall (UNR) for helpful conversations and/or logistical help with my research. This work could not have been completed without the assistance of the staff of the Ecology Center, including Susan Durham, Marv Bennett, and Stephanie White, and Lana Barr and Gaye Griffith from the Department of Wildland Resources. I am also grateful to the past and current members of the Schupp lab: Tarek Milleron, Jeff Burnham, Kelly Sivy, Dan Christensen, Melissa Harvey-LaMalfa, Ryan Barker, and Tyler Logan especially. I am also grateful to Greg Larson, Lisa Ellsworth, Jacob Landmessor, Rob Klinger, Bill Fox, Amanda Murray, and Vijay Satyal for all their help and/or encouragement. In the pursuance of this doctoral degree the encouragement and assistance of my family and friends were critical. I am grateful to my sister, Susan Halsted, my grandparents Eva and Frank Ostoja, and my mother Joey Halsted, who are kind, caring, and encouraging people. Akin to the many wonderful qualities of my mom, Emily Bradley is not only the most loving and understanding partner I could ever hope to know, she was very understanding when my main focus was realizing the completion of this work. Not to mention, Emily has an uncanny hand with kangaroo rats.

  • Vegetation Responses to Past Volcanic Disturbances at the Araucaria
    Vegetation responses to past volcanic disturbances at the Araucaria araucana forest-steppe ecotone in northern Patagonia Ricardo Moreno-Gonzalez1 1University of G¨ottingen July 22, 2021 Abstract Aims Volcanic eruptions play an important role in vegetation dynamics and its historical range of variability. However, large events are infrequent and eruptions with significant imprint in today vegetation occurred far in the past, limiting our un- derstanding of ecological process. Volcanoes in southern Andes have been active during the last 10 ka, and support unique ecosystems such as the Araucaria-Nothofagus forest as part of the Valdivian Temperate Rainforest Hotspot. Araucaria is an endangered species, strongly fragmented and well adapted to disturbances. Yet it was suggested that volcanism might have increased the fragmentation of its populations. To provide an insight into the vegetation responses to past volcanic disturbances, a paleoecological study was conducted to assess the role of volcanic disturbance on the vegetation dynamics and if the current fragmentation has been caused by volcanism. Location Araucaria forest-steppe ecotone in northern Patagonia. Methods Pollen and tephra analysis from a sedimentary record. Results During the last 9 kyr, 39 tephrafall buried the vegetation around Lake Relem, more frequently between 4-2 ka. The vegetation was sensitive to small tephrafall but seldom caused significant changes. However, the large eruption of Sollipulli-Alpehue (~3 ka) might change the environmental conditions affecting severely the forest and grassland, as suggested by the pollen record. Ephedra dominated early successional stage, perhaps facilitating Nothofagus regeneration recovering original condition after ~500 years. Slight increase of pollen percentage from Araucaria and Nothofagus obliqua-type could be indicative of sparse biological legacies distributed in the landscape.

A 10 year trial with SouthAmerican trees and shrubswith specialregard to the Ir,lothofaglzsspp. I0 6ra royndir vid suduramerikonskumtroum og runnum vid serligumatliti at Nothofagw-slogum SarenOdum Abstract The potential of the ligneous flora of cool temperate South America in arboriculture in the Faroe Isles is elucidated through experimental planting of a broad variety of speciescollected on expeditions to Patagonia and Tierra del Fuego 1975 andl9T9.Particular good results have been obtained with the southernmost origins of Nothofagus antarctica, N. betuloides, and N. pumilio, of which a total of 6.500 plants were directly transplanted from Tierra del Fuego to the Faroe Isles in 1979. Soren Odum, Royal Vet.& Agric. IJniv., Arboretum, DK-2970 Horsholm, Denmark. Introduction As a student of botany at the University of CopenhagenI got the opportunity to get a job for the summer 1960as a member of the team mapping the flora of the Faroe Isles (Kjeld Hansen 1966). State geologist of the Faroe Isles and the Danish Geological Survey, J6annesRasmussen, provided working facilities for the team at the museum, and also my co-student,J6hannes J6hansen participated in the field. This stay and work founded my still growing interest in the Faroese nature and culture, and the initial connections between the Arboretum in Horsholm and Tbrshavn developed from this early contact with J6annesRasmussen and J6hannes J6hansen. On our way back to Copenhagen in 1960 onboard "Tjaldur", we called on Lerwick, Shetland, where I saw Hebe and Olearia in some gardens. This made it obvious to me, that if the Faroe Isles for historical reasonshad been more or less British rather than Nordic, the gardensof T6rshavn would, no doubt, have been speckledwith genera from the southern Hemisphere and with other speciesand cultivars nowadays common in Scottish nurseries and gardens.

Nothofagaceae (southern beeches) are a relatively small flowering plant family of trees confined to the Southern Hemisphere. The fossil record of the family is abundant and it has been widely used as a test case for the classic hypothesis that Antarctica, Patagonia, Australia and New Zealand were once joined together. Although the phylogenetic relationships in Nothofagus appear to be well supported, the evolution of some pollen morphological traits remains elusive, largely because of the lack of ultrastructural analyses. Here we describe the pollen morphology of all extant South American species of Nothofagus, using scanning electron microscopy (SEM), transmission electron microscopy (TEM) and light microscopy (LM), and reconstruct ancestral character states using a well-supported phylogenetic tree of the family. Our results indicate that the main differences between pollen of subgenera Fuscospora (pollen type fusca a) and Nothofagus (pollen type fusca b) are related to the size of microspines (distinguishable or not in optical section), and the thickening of colpi margins (thickened inwards, or thickened both inwards and outwards).
