ABSTRACT.-Only 0.02% of historic oak savanna exists today. To provide management recommendations, we characterized age-class structure, measured cover of competing tree species and estimated genetic variation within and among four Quercus macrocarpa...

ABSTRACT.-Overgrazing, weed invasion and wildfire have resulted in the conversion of large areas of shrub steppe to exotic annual grassland in the western United States. This has been accompanied by reduced habitat for native plants and animals, and...

ABSTRACT.-In recent decades, an increasing number of plant species have been negatively affected by anthropogenic habitat fragmentation and disturbance. In many cases, the habitat matrix between populations has been converted from a natural to an urban...

ABSTRACT. - Celastrus orbiculatus is a non-native, invasive liana that was introduced to the United States in the 1860s and has spread rapidly throughout the Northeast. Several attributes contribute to the invasiveness of C. orbiculatus, including tolerance...

ABSTRACT.-The prairie mole cricket (Gryllotalpa major Saussure) is a rare endemic of the tallgrass prairie ecosystem of the south central United States. Males advertise for females using a low frequency acoustic signal from surface burrows aggregated...

ABSTRACT. - The purpose of scientific writing is to impart thoughts or ideas and their bases and implications in such a manner that a reading audience, with at least a moderate knowledge of science, can understand the material presented within a paper....

ABSTRACT.-Plant invasions have been hypothesized to proceed at the local scale (i.e., individual patch or stand) according to one of several distinct spatial patterns. However, few studies have attempted to reconstruct the patterns of perennial herbaceous...

Noninvasive Survey Methods for Carnivores, Long, Robert A., Paula MacKay, William J. Zielinski, Justina C. Ray, Island Press, Washington, 2008. 385 p."Noninvasive Survey Methods for Carnivores" is one of the first major published books to emerge on this...

ABSTRACT.-In Part I (Livezey, 2009), I presented the chronology and distribution of the range expansion of Barred Owls (Strix varia) from the late 1800s to the present. Here I explore what had prevented Barred Owls from expanding their range westward...

ABSTRACT.-Information regarding survival and cause-specific mortality of eastern wild turkeys (Meleagris gallopavo silvestris) is vital to their management, especially in small or isolated populations. Between January 2003 and August 2005, we used radio...

ABSTRACT.-A 1.44 ha plot in a disjunct Tsuga canadensis-dominated forest in southern Wisconsin was mapped and examined for 25 y. Every 5 y between 1981 and 2006, all of the trees = 2.54 cm dbh were measured and mortalities and additions were noted. The...
