Renesting Decisions And Annual Fecundity Of Female Dickcissels (Spiza Americana) In Illinois, Jeffrey Walk, Kevin Wentworth, Eric Kershner, Eric Bollinger, Richard Warner Oct 2004

Renesting Decisions And Annual Fecundity Of Female Dickcissels (Spiza Americana) In Illinois, Jeffrey Walk, Kevin Wentworth, Eric Kershner, Eric Bollinger, Richard Warner

Faculty Research & Creative Activity

ABSTRACT.-Renesting decisions and annual fecundity are crucial for interpreting other demographic information, yet are infrequently reported. We used radiotelemetry to monitor female Dickcissels (Spiza americana) throughout the 1999 and 2000 breeding seasons in southeastern Illinois. Overall fecundity (regardless of whether females remained in the study area throughout the breeding season) was 0.61 ± 0.13 female fledglings per year. Of females that remained within the study area, 94% fledged young (1.25 ± 0.15 female fledglings per year). Most females (62%) that experienced nest failure emigrated from the study area (moved >10 km) in 2.8 ± 0.6 days; others (36%) initiated subsequent …


Germination Of Silene Regia Seeds From Four Sites In Lawrence County, Illinois, Following Scarification Or Stratification, Nicolette Flocca, Janice Coons, Henry Owen, Brian Fischer, Bob Edgin Oct 2004

Germination Of Silene Regia Seeds From Four Sites In Lawrence County, Illinois, Following Scarification Or Stratification, Nicolette Flocca, Janice Coons, Henry Owen, Brian Fischer, Bob Edgin

Faculty Research & Creative Activity

Silene regia Sims is an endangered prairie forb in Illinois where small isolated colonies are scattered. In La·wrence County, two sites (Allison Prairie and Chauncey Marsh) have fewer plants (6-23) than two other sites (Cmmty Road and Cemetery) with 26-45 plants. Information on seed germination in these isolated colonies is needed. Our goal was to evaluate seed germination of S. regia from colonies in Lawrence County, illinois. S. regia fruits were collected from these four sites on August 9 and 19, 1999. Seeds were scarified by cutting the seed coat, or they were stratified at 2 C for 12 or …

Responses Of Nesting Bobolinks (Dolichonyx Oryzivorus) To Habitat Edges, Eric K. Bollinger, Thomas A. Gavin Jul 2004

Responses Of Nesting Bobolinks (Dolichonyx Oryzivorus) To Habitat Edges, Eric K. Bollinger, Thomas A. Gavin

Faculty Research & Creative Activity

T.-Avoidance of habitat edges may be contributing to reduced densities of grass- land birds in small habitat patches. Nest densities for grassland-nesting Bobolinks (Dolichonyx oryzivorus) were much lower than expected within 25 m of forest edges at three sites in New York, and that pattern ("edge avoidance") extended to 100 m at one site. Nests located within 50 m of forest or wooded hedgerow edges had lower daily survival rates, compared with nests >100 m from any habitat edge. Bobolinks tended to move away from forest edges when renest- ing after nest failure; that pattern was especially evident in females …
