Nesting success and status of the least tern breeding colony at gibson lake in southwestern indiana

Least Tern (Sternula antillarum) Science Article 6 abstract Federally-endangered interior least terns (Sterna antillarum) have nested at Gibson Lake in southwestern Indiana since 1986. In 2003 and 2004 we evaluated nesting success of least terns and identified factors influencing their productivity at Gibson Lake . In 2003 least terns nested only at secondary breeding sites, […]

REPRODUCTIVE SUCCESS OF THE INTERIOR LEAST TERN(STERNA ANTILLARUM) IN RELATION TO HYDROLOGY ON THELOWER MISSISSIPPI RIVER

Least Tern (Sternula antillarum) Science Article 3 abstract The annual hydrograph of large rivers, including flood pulses and low-flow periods, is believed to play a primary rolein the productivity of biota associated with these ecosystems. We investigated the relationship between riverhydrology and Interior least tern (Sterna antillarum) reproductive success on the Lower Mississippi River from […]

Genetic Variation among Subspecies of Least Tern(Sterna antillarum): Implications for Conservation

Least Tern (Sternula antillarum) Science Article 2 abstract DNA sequence variation from two nuclear introns and part of the mitochondrial cytochromebgenewere used to evaluate population structure among three subspecies of Least Tern that nest in the United States (California[Sterna antillarum browni], Interior [S. a. athalassos], Eastern [S. a. antillarum]). Sequence variation was highestfor nuclear intron […]

Evidence for Reproductive Mixing of Least Tern Populations

Least Tern (Sternula antillarum) Science Article 4 abstract The Atlantic race of the Least Tern (Sterna antillarum antillarum) breeds along the coastal beaches and bay systems of the Atlantic Ocean and Gulf of Mexico from Maine to southern Texas, while the Interior Least Tern (S. a. athalassos) breeds in the interior of the United States […]

NOCTURNAL PREDATIONOF CALIFORNIA LEAST TERNS AT A SOUTHERN CALIFORNIA LEAST TERN

Least Tern (Sternula antillarum) Science Article 5 abstract Predation is difficult to observe and quantification of impacts have consequentlybeen difficult, especially for predators active at night. Using night-capable camerasplaced throughout a California least tern (Sternula antillarum browni) colony I examinedrates of predation by a complex of potential predators. I identified and quantified directand indirect effects […]
