(Texas A&M University. Libraries, 1980)A geographically referenced data base of the native pecan in portions of Texas was compiled from color infrared aerial photographs at a scale of 1/10,000. The Universal Transverse Mercator grid system was employed to ...
-
(Texas A&M University. Libraries, 1986)Karyotypic data from a total of 574 deer mice from insular populations off British Columbia and Washington indicate the presence of two distinct karyotypic groups, a "low FN" group (FN = 74-78) and a "high FN" group (FN = ...
-
(Texas A&M University. Libraries, 1987)Karyotypic data are presented for a total of 723 individuals of Peromyscus boylii from Latin America. The range of karyotypic variation now documented in P. boylii (FN = 47-68) is greater than that known for any other ...

(Texas A&M University. Libraries, 1976)The distribution and abundance of meiofauna and macroinfauna from ten stations on the outer east Texas continental shelf were examined. The meiofauna ranged from 519 to 896 individuals per 10 cm² and 3.95 to 6.49 mg wet ...

(Texas A&M University. Libraries, 1984)Seventeen Multiple Opening/Closing Net and Environmental Sensing System hauls were taken in the California Current at a depth of 90m and with a sample interval of 50m over a period of three days and three nights. Thirteen ...
-
(Texas A&M University. Libraries, 1987)To examine the fine-scale patchiness of zooplankton and related sample variability in the coastal area off Louisiana, zooplankton samples were collected for one night and two days in October 1985 using a 1 m² Multiple ...

(Texas A&M University. Libraries, 1986)Starch-gel electrophoresis and karyology were employed to establish more precise species circumscriptions in the taxonomically troublesome thallose liverwort Riccia L. subgenus Riccia and to survey variation among natural ...
