americanus/trap-night on individual transects
The double-observer method was used in conjunction with the line-transect
survey to test the assumption that detection was 100% on or near the transect
centerline, or at the minimum available sighting distance (Buckland et al.
sti] denotes the ith scallop count in transect
t within survey s, where t and s are considered random factor levels with replications, with t nested within s.
For assessment of extralimital effects of harvesting based on transect
sampling, categories were treatment (samples collected in cultured plots and reference plots vs.
We found support, based on our transect
survey method, for scrub-jays as habitat generalists, which is consistent with previous scrub-jay research in this area (Burt, 1996).

provides groundbreaking biotechnology tools for improving crop climate resilience and educating a workforce that understands the effects of climate change on plant adaptation,” said Kelvin Chu, program director at the NSF.
Recorded sighting data included date, time, vessel latitude and longitude, vessel true heading, distance of animal from the vessel, sighting angle, 0, from the transect
line, determined with an angle board (zero at bow, negative to port, positive to starboard), sighting number, species, group-size estimate (best, high, low), presence of calves, general behavior of animals, photographs (if taken), and comments pertaining to the sighting.
Linear regression analysis was used to examine whether the transect
counts and hide digestion counts were correlated.
Sampling was performed in August 1995 and 1996 on 10 transects
located around the whole coastline of the Gulf of Riga (Fig.

Across the chronosequence we observed an increase in the number of native species both per transect
