Flood Survival Strategies of Overwintering Snakes
… variability may affect habitat quality and overwintering survival. Chapter one reviews the current understanding of ecophysiology of hibernation in snakes. In chapter two, I introduce a winter habitat model of a subterranean space that remains flood and frost-free, referred to as the “life …

Overwintering Mechanisms of La Crosse Virus Vectors
The La Crosse virus (LACV) is an emerging pathogen in the Appalachian region of the United States. The virus maintains a complex natural cycle through horizontal transmission with sciurid rodents and Aedes mosquitoes in Virginia. Transovarial transmission also occurs in this host-parasite system …

Increasing the overwintering survival of container-grown perennials
… but little research has been reported on proper overwintering techniques for herbaceous perennials and ornamental grasses. In the first experiment rooted liners of Pennisetum alopecuroides, Pennisetum "Hameln" and Pennisetum "Little Bunny," were potted. Treatments included, utilizing two …

Selection of Overwintering Microclimate by Migratory Western Monarch Butterflies
… locations along the California coast. To date, overwintering habitat selection by western monarch butterflies has been studied assuming that habitat selection occurs where overwintering aggregations form, meaning at the spatial scale where monarchs form dense overwintering aggregations within …

Overwintering Biology of Culex Pipiens Linnaeus (Culicidae) in East-Central Illinois
… species collected from the Champaign-Urbana, overwintering site. Temperature was the key factor in resting site choice by these females, with most found in the coldest areas of the site throughout the overwintering season. Furthermore, results suggested that temperature affected both follicle …

Murgantia histrionica (Hahn): new trapping tactics and insights on overwintering survival
Harlequin bugs are orange and black aggregation pheromone emitting stink bug pests, specifically of cole crops such as kale, broccoli and collards. This nearly loyal crop preference makes an interesting challenge for trapping them and helping farmers predict pest severity. Harlequin bugs can be …

Overwintering biology of the brown marmorated stink bug, Halyomorpha halys (Hemiptera: Pentatomidae)
… diapause in enhancing stress tolerance. Overwintering H. halys depress their supercooling point to -15.4 °C and LT50 to -17.5 °C after acute (1 h) exposure, however they do not encounter these temperatures while overwintering indoors. Moreover, overwintering H. halys maintain their water …

Modelling the sustainability of overwintering Mnemiopsis leidyi populations in the North Sea
… examine the origin and sustainability of these overwintering M. leidyi individuals. The main results of this research are: (i) the model suggests it is possible there exists a UK population of M. leidyi somewhere along the English coast that has thus far gone undetected; (ii) M. leidyi can …

Vocalizations influence roost-site selection in overwintering cavity-nesting birds in Eastern Washington
<p>Primary cavity-nesting birds are keystone species because the annual tree cavities they excavate become critical habitat for other species. In eastern Washington, most primary cavity-nesting birds are year-round residents. They increase overwinter survival by night roosting in cavities and …

Monarch Butterfly (Danaus plexippus) Tree Preference and Intersite Movement at California Overwintering Sites
<p>Managing Monarch butterfly overwintering groves: making room among the eucalyptus</p> <p>Proper management and conservation of the coastal California overwintering sites used by western Monarch butterflies <em>(Danaus plexippus </em>L.) is critical for continued use of these sites by monarchs. …

Population dynamics of overwintering life stages of the alfalfa weevil, Hypera postica (Gyllenhal)
Virginia is a natural laboratory for studying overwintering habits of the alfalfa weevi1. At higher elevations, winters are relatively harsh and weevil pressure on the alfalfa crop is usually light. Much heavier pressure is the rule at lower elevations where winters are milder. The goal of this …

The impact of urban centers on American goldfinches (Spinus tristis) overwintering at high latitudes
<p>American Goldfinches (<em>Spinus tristis</em>) are partial migrants that overwinter in northern regions where winters can be extreme. To understand the role of urban development in facilitating use of a harsh climate, I conducted winter point count surveys (n = 297) at urban and rural sites …
