Bull. Torrey Bot. Club 121: 357-359. 1994.-The age structure of red maple (Acer rubrum L.) in two agricultural fields that were abandoned 16 and 20 yr ago was investigated in order to determine the timing of this species' invasion during the North Carolina piedmont old field successional sequence. At the 20 yr old site, red maples in the 6-12 yr age classes accounted for 78% of the individuals measured, and individuals in the 2-5 and 13-20 yr age classes were poorly represented. Individuals in the 2-7 yr age classes made up 86% of the red maples sampled at the 16 yr old site. These data suggest that most successful red maple establishment in the early phase of the piedmont successional sequence does not occur until 6-9 yr after abandonment of the field. The results of this study contrast with those identified by Rankin and Pickett's (1989) study of red maple invasion in a New Jersey old field, which indicated that most successful invaders established within the first 2 yr after abandonment. Local and regional variation in the opening and closing of establishment windows for red maple during old field successional sequences may result from differences in climate, soils, seed predation, seed availability, site size and shape, or herbivory.","PeriodicalId":9453,"journal":{"name":"Bulletin of the Torrey Botanical Club","volume":"121 1","pages":"357"},"PeriodicalIF":0.0,"publicationDate":"1994-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2307/2997009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68413713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Picea rubens saplings were more frequently found on mounds than other microtopographical positions, but not on mounds that were of recent origin. Picea rubens saplings had an unimodal age-structure characteristic of an even-aged population, which suggests a pattern of episodic regeneration coincident with local windthrow disturbance. Picea rubens that occurred on mounds, rocks, and intact areas tended to be larger and older than those found in pits. The establishment and survival of juvenile P. rubens were limited by the availability of microsites coincident with good seed years, and the suitability of microsites for growth once stems were established. Terminal and lateral growth increments of P. rubens saplings were similar among microtopographical positions and between reference and limed subcatchments before and in the two years after liming. In 1992, the terminal increment of P. rubens was not different from the 1991 terminal increment on treated subcatchments, but in reference subcatchments the terminal increment was less than in 1991. The potential role of P. rubens in future forests is discussed.","PeriodicalId":9453,"journal":{"name":"Bulletin of the Torrey Botanical Club","volume":"121 1","pages":"345-356"},"PeriodicalIF":0.0,"publicationDate":"1994-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2307/2997008","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68413706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Club 121: 215-229. 1994.-Climatic and flowering data from a site in the northern Sonoran Desert of southern Arizona were used to define flowering triggers and developmental requirements for 6 woody plants. These formulations were then used to predict flowering dates at a second northern Sonoran Desert site. It was determined that flowering is triggered by rain in Larrea tridentata (DC.) Cov., Fouquieria splendens Engelm., Encelia farinosa A. Gray, Ambrosia deltoidea (A. Gray) Payne and Acacia constricta Benth., and that flowering is triggered by photoperiod in Cercidium microphyllum (Torr.) Rose & Johnst. The base temperature for floral development in L. tridentata, F. splendens, E. farinosa, A. deltoidea and C. microphyllum is about 10?C. Their mean degree-day requirements range from 414 to 719. Acacia constricta requires 522 degree-days above 15?C. Minimum rainfall triggers varied from 9 mm forAmbrosia to 20 mm for Encelia. Flowering time in C. microphyllum may reflect phylogenetic constraints, while flowering time in F. splendens may be strongly influenced by pollinator availability. Flowering times of the remaining species seem constrained more by climate than by biotic considerations such as phylogeny, seed germination and competition for pollinators.","PeriodicalId":9453,"journal":{"name":"Bulletin of the Torrey Botanical Club","volume":"121 1","pages":"215"},"PeriodicalIF":0.0,"publicationDate":"1994-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2307/2997177","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68415377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on tree recruitment and radial growth patterns, low-intensity exogenous disturbances occurred every 30-60 yr during the presettlement era. Extensive logging during the mid- I 840s was evident throughout the area, and, along with subsequent disturbances, had a profound effect on current forest composition and structure. Tree species responded differently to major anthropogenic disturbance, in terms of growth rate and canopy positioning. In general, Pinus strobus L., Liriodendron tulipifera L. and Quercus responded favorably to disturbance, whereas Acer, Betula alleghaniensis Britton and Tsuga canadensis (L.) Carr recovered more slowly. Current forest age structures reflect different disturbance patterns and rates of recovery, and were categorized as either even-aged, uneven-aged consisting of 2 distinct even-aged cohorts, or uneven-aged with extended recruitment (multiple small-scale disturbances). Successional patterns currently exhibited in all forests may be drastically altered in the future from overbrowsing by whitetailed deer (Odocoileus virginianus) and/or intense shrub competition on tree regeneration.","PeriodicalId":9453,"journal":{"name":"Bulletin of the Torrey Botanical Club","volume":"121 1","pages":"277"},"PeriodicalIF":0.0,"publicationDate":"1994-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2307/2997182","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68415496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Club 121: 230-239. 1994.-Eight or more weeks of cold stratification (5?C) were required to break dormancy in achenes of Bidens laevis (L.) BSP from a tidal freshwater wetland. When achenes began to come out of dormancy, they germinated to 50% first at 35/20?C, and then with additional stratification the minimum temperature for 50% germination decreased to 1 5/6?C. Germination of stratified achenes was inhibited by darkness and was completely prevented by hypoxia (inundation in closedjars). Seeds inundated in openjars and those in Petri dishes, however, germinated to > 80%. Germination declined sharply with depth of burial (0, 1, and 5 cm). Moisture regime (drained, saturated, and inundated) also significantly affected germination, but afterripening condition (cold greenhouse or 5?C) altered the effect. Interaction between depth of burial and moisture regime was significant (P 1 yr) following winter afterripening of achenes in the field.","PeriodicalId":9453,"journal":{"name":"Bulletin of the Torrey Botanical Club","volume":"121 1","pages":"230"},"PeriodicalIF":0.0,"publicationDate":"1994-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2307/2997178","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68415418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
