And Behavior

Abstract Nesting behavior in the Northern Pine Snake (Pituophis m. melanoleucus) is poorly documented outside of the New Jersey Pine Barrens. Two natural nests of P. m. melanoleucus are described from the North Carolina Sandhills. One was modified from a pre-existing subterranean refugium, and was also used by at least one adult male; one adult female; and one post-emergent, post-ecdytic hatchling Pine Snake during the same season.

AbstractCalathura brachiata (Stimpson, 1853) has been found in the North Atlantic, north of Iceland and northeast of Greenland; 750 specimens have been investigated. Although this species is quite large and widely distributed, the identification was complicated by the fact that the synonymy with Calathura norvegica (Sars, 1872) and Anthura arctica (Heller, 1875) had not yet been satisfactorily resolved. Moreover, the descriptions of these species were either incomplete, or it was difficult to recognize the species from the illustrations. We therefore present a complete redescription of manca stages 2 and 3, as well as of an adult female, on the basis of our material from the North Atlantic, together with a redescription of an adult male based on museum material.

Seeds of six provenances (Escambia Co., Ala.; Santa Rosa Co., Fla.; Wayne Co., N.C.; Burlington Co., N.J.; New London Co., Conn.; and Barnstable Co., Mass.) of Atlantic white-cedar [Chamaecyparis thyoides (L.) B.S.P.] were stratified (moist-prechilled) for 0, 30, 60, or 90 days at 4 °C. Following stratification, seeds were germinated at 25 °C or an 8/16-hour thermoperiod of 30/20 °C with daily photoperiods at each temperature of 0 (total darkness), 1, or 24 hours. The germination of nonstratified seed did not exceed 18%. Seeds germinated at 25 °C required 60 to 90 days stratification to maximize germination. In contrast, 30 days stratification maximized germination at 30/20 °C. Regardless of stratification duration, germination was generally lower at 25 °C than at 30/20 °C for each provenance. Averaged over all treatments, seeds of the Alabama provenance exhibited the greatest germination (61%), followed by those from Florida (45%), with the remaining provenances ranging from 20% to 38%. However, specific treatments for each provenance induced germination >50%. Germination of seeds not exposed to light was <8%, in contrast with 48% and 55% germination for daily photoperiods of 1 and 24 hours, respectively. Seeds from each of the provenances, except for Alabama, exhibited an obligate light requirement when germinated at 25 °C. At 30/20 °C, the North Carolina, New Jersey, Connecticut, and Massachusetts provenances required light for germination, whereas the Alabama and Florida provenances did not.

Uniform seedlings of six provenances (Escambia Co., Ala.; Santa Rosa Co., Fla.; Wayne Co., N.C.; Burlington Co., N.J.; New London Co., Conn.; and Barnstable Co., Mass.) of Atlantic white cedar [Chamaecyparis thyoides (L.) B. S. P.], were transplanted in Apr. 1997 into 0.95-L plastic containers with a medium of 1 peat: 1 perlite: 1 vermiculite (v/v). Plants were acclimatized at 26/22 °C under a 16-hr photoperiod for 2 weeks before treatment initiation. Fourteen seedlings per provenance were then transferred to each of five growth chambers maintained at 16/8 hr thermoperiods of 22/18 °C, 26/22 °C, 30/26 °C, 34/30 °C, or 38 /34 °C with a 16-hr photoperiod of 550–600 μmolμm–2μs–1. Seedlings were arranged in a split-plot design with a 5 × 6 factorial arrangement of treatments (5 temperatures × 6 provenances). Plants were harvested 12 weeks after treatment initiation and data recorded. Temperature had a significant effect on overall growth with responses to temperature varying according to provenance. There was a highly significant (P ≤ 0.0001) temperature × provenance interaction for height, stem caliper (measured below the lowest leaf), and foliar, stem, root, and shoot (foliar dry weight + stem dry weight) dry weights. Top and root dry weights were maximized for the northern provenances (Connecticut and Massachusetts) at 22/18 °C. At 26/22 °C and 30/26 °C, the northern provenances (Connecticut and Massachusetts) had the lowest top and root dry weights. However, the southern provenances (Alabama, Florida, and North Carolina) had the greatest top dry weights at 26/22 °C. At 30/26 °C, the southern provenances (Alabama and Florida) and the New Jersey provenance had the greatest top dry weights but they were not significantly different from 26/22 °C. Root dry weights were not significantly different between 26/22 °C and 30/26 °C for the Alabama and New Jersey provenances, but were significantly different for the North Carolina and Florida provenances. Regardless of provenance, dramatic reductions occurred for all growth measurements when temperatures exceeded 30/26 °C. For top and root dry weights, there were no significant differences among the six provenances at 34/30 °C and 38/34 °C. All plants at the highest temperatures of 38/34 °C did not survive by week 8.

And Behavior

On 11 March 1987 an adult female bighorn sheep (Ovis canadensis californiana) with abnormally large horns was captured in the badlands of North Dakota. Subsequent observations of this individual suggested malelike behavior. Possible explanations of this abnormal horn growth and behavior are a genetic defect or an endocrine imbalance.
