Karyotypic Analysis Of Five Rodents And A Marsupial From Belize, Central America, David W. Burton, John W. Bickham, Hugh H. Genoways, Timothy J. Mccarthy

University of Nebraska State Museum: Mammalogy Papers

Karyotypes and chromosomal banding patterns of six species of small mammals from Belize are presented and discussed in light of relevant data in the literature. Individuals of Heteromys desmarestianus had FN values of 72, which differs from previous reports. G-bands were obtained and compared to fluorescent bands (DAPI) and with the location of NOR sites. The karyotypes of Peromyscus mexicanus, Sigmodon hispidus, Oryzomys couesi, and Ototylomys phyllotis are identical to the karyotypes for these species described in the literature. Active NORs were located on four pairs of chromosomes in O. phyllotis and fluorescent bands obtained with the …

Morphological Variation, Karyology, And Systematic Relationships Of Heteromys Gaumeri (Rodentia: Heteromyidae), Mark D. Engstrom, Hugh H. Genoways, Priscilla K. Tucker

University of Nebraska State Museum: Mammalogy Papers

Morphological variation was assessed within and among populations of Heteromys gaumeri using univariate and multivariate statistical analyses of external and cranial measurements. Although patterns and amount of nongeographic variation in H. gaumeri were similar to other heteromyines, geographic variation was relatively conservative. Mean values of most characters were statistically homogeneous among localities and spatially unpatterned. Consequently, no association was found between levels of within- and among-sample variation for individual characters (the "Kluge-Kerfoot phenomenon"). Populations of H. gaumeri were chromosomally monomorphic. The lack of morphological and chromosomal variation in H. gaumeri contrasts sharply with patterns in other heteromyines. Heteromys gaumeri is …

A Synthetic Approach To The Study Of Animal Intelligence, Alan Kamil

Papers in Behavior in Biological Sciences

Psychologists have been studying animal learning for about a century. This century of experimental and theoretical work has produced some remarkable successes, particularly in understanding basic conditioning processes. However, these successes are limited in two major ways. First, they have been confined to a narrow domain. Recent research from a variety of settings has demonstrated that animals have mental abilities far beyond what they were given credit for just a few years ago. We must dramatically expand the range of phenomena addressed by the study of animal learning. Second, there has been an almost complete failure to place animal learning …

New And Corrected Records Of The Flora Of Nebraska, Steven B. Rolfsmeier, Robert B. Kaul, David M. Sutherland

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

New distributional data are provided for 27 species of vascular plants in Nebraska, eight newly recorded as growing wild in the State. The record of one species previously attributed to the State is shown to be based upon misidentified specimens, the range of another is shown to be much more restricted in Nebraska than previously reported, and nomenclature is corrected for two species.

The Characteristics And Phytogeographic Affinities Of The Flora Of Nine-Mile Prairie, A Western Tall-Grass Prairie In Nebraska, Robert B. Kaul, Steven B. Rolfsmeier

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Three hundred ninety-two species, subspecies, and varieties have been recorded at Nine-Mile Prairie, a relict tall-grass prairie that has been reduced from 323 to 97 ha in the past 50 years. There are 218 native and 17 introduced herbaceous perennial species, and 73 native and 24 introduced annuals. Analogous numbers for biennials are 15 and 11, for shrubs are 14 and one, for trees are ten and three, and for woody vines are six and none. One hundred twenty-one native species are of central and eastern North American phytogeographic affinity, and 109 are of transcontinental affinity. Seventy-nine of the Prairie's …

Alloparental Care In The Prairie Skink, Eumeces Septentrionalis: A Case Of Mistaken Identity?, Louis A. Somma

Papers in Herpetology

Alloparental care , or one individual caring for the eggs or young of another , ha s been documented for a variety of verte brate organism s (Coyne & Sohn 1978; Frame et a1. 1983; Gowaty & Karlin 1984) . In t h i s a rticle I document an instance of alloparental care in the prairie skink , Eumeces septentrionalis .
