Diel host-seeking activity of adult Chrysops celatus Pechuman was studied in northwestern Florida during June 1993 and 1994. Primary peak activity occurred at 0645 h (CST) with a secondary peak at 1945 h. Host-seeking behavior was correlated with relative humidity but not temperature and light intensity. No host-seeking activity was observed at darkness. In all studies, the majority of flies in...

Uteri from four pregnant females and two newborn of shortfin mako, Isurus oxyrinchus, were collected in the southeastern region of Brazil, during September, October, and November of 1993 and 1994. All embryos were near-term with developing dentition and inner organs. Total length ranged from 64.5 to 72.0 cm, and the maximum number of embryos observed in a litter was 20. These observations furth...

Germination ability and airborne counts of Scots pine (Pinus sylvestris L.) pollen were studied during the spring of 1993 at Turku in southern Finland (60 degrees 32' N, 22 degrees 28' E) and at Utsjoki in northern Finland (69 degrees 45' N, 27 degrees 01' E). Pollen waas trapped from the beginning of May to the end of June in a high-volume air sampler. Germination tests were performed to deter...

The effects of infection by tobacco cyst nematode (Globodera tabacum solanacearum) on growth of flue-cured tobacco cultivars NC 567 (resistant) and K 326 (susceptible) were evaluated in the field in 1993 and 1994. Infection by G. t. solanacearum suppressed number of leaves, plant height, and fresh weight of leaves and feeder roots. Correlations between weekly egg densities of G. t. solanacearum...

Sea-level change is one of the most concerning climate and global warming consequences, especially impacting coastal societies environments. The spatial temporal variability sea level neither linear nor globally uniform, in semi-enclosed basins such as Mediterranean Sea, which considered a hot spot regarding expected impacts related to change. This study investigates sea-level trends their over...
