Mechanism and active variety of allelochemicals Mechanism and active variety of allelochemicals
This article summarizes allelochemicals' active variety, its potential causes and function mechanisms. Allelochemicals' activity varies with temperature, photoperiod, water and soils during natural processes, with its initial concentration, compound structure and mixed degree during functional processes, with plant accessions, tissues and maturity within-species, and with research...

The flora of the Cottonwood Lake Study Area, Stutsman County, North Dakota The flora of the Cottonwood Lake Study Area, Stutsman County, North Dakota
The 92 ha Cottonwood Lake Study Area is located in south-central North Dakota along the eastern edge of a glacial stagnation moraine known as the Missouri Coteau. The study area has been the focus of biologic and hydrologic research since the U.S. Fish and Wildlife Service purchased the site in 1963. We studied the plant communities of the Cottonwood Lake Study Area from 1992 to 2001...

Guidelines for finding nests of passerine birds in tallgrass prairie Guidelines for finding nests of passerine birds in tallgrass prairie
The productivity of birds is one of the most critical components of their natural history affected by habitat quality. Birds might occur at high densities in a given habitat patch but have low nesting success. Such "population sinks" would not be detected if observers relied solely on estimates of bird density. Therefore, it is essential to monitor nests and determine their outcomes...

Historical and recent records and first nest records of Henslow's sparrow in North Dakota Historical and recent records and first nest records of Henslow's sparrow in North Dakota
The northwestern limit of the Henslow's sparrow (Ammodramus henslowii) breeding distribution occurs in southern Minnesota and central Wisconsin. In North Dakota, observations of Henslow's sparrows are reported infrequently, and there are no published nest records in the state. Herein, we summarize and review previous reports of Henslow's sparrows in North Dakota and document the first...

Status assessment and conservation plan for the Western Burrowing Owl in the United States Status assessment and conservation plan for the Western Burrowing Owl in the United States
The Western Burrowing Owl (Athene cunicularia hypugaea) is a grassland specialist distributed throughout w. North America, primarily in open areas with short vegetation and bare ground in desert, grassland, and shrub-steppe environments. Burrowing Owls are dependent on the presence of fossorial mammals (primarily prairie dogs and ground squirrels), whose burrows are used for nesting and...

Life history, diversity and distribution: A study of Japanese pteridophytes Life history, diversity and distribution: A study of Japanese pteridophytes
Many studies address the relationships between diversity or distribution and attributes of the physical environment. However, how these relationships are connected to variation in life history is poorly understood. This is particularly true in the case of pteridophytes. Japanese ferns and their allies comprise one of the best-known pteridophyte floras in the world. We analyzed ca 600...

Sampling designs for carnivore scent-station surveys Sampling designs for carnivore scent-station surveys
Scent stations usually are deployed in clusters to expedite data collection and increase the number of stations that can be operated for a given cost. Presumed benefits of cluster sampling may not be realized, however, unless cluster sizes are chosen with respect to sampling variation within and among clusters. To encourage and facilitate the use of efficient designs and reporting...
