and forest plants and clarify some of 

 the morphological discrepancies in the 

 literature. He has done anatomical and 

 histological work on the development 

 of canker in peach trees, a serious 

 disease in which the complex nature 

 of the host-pathogen interaction has 

 hampered selection of resistant stocks. 



A question intriguing T. D. Lee, 

 reproductive ecologist, is what limits 

 fruit production in plants. While it is 

 well established that many angio- 

 sperms begin developing more fruit 

 than they can mature with available 

 resources, little is known about the 

 process of fruit abortion. Lee has found 

 that fecundity of a plant is determined 

 by the number of fruits it matures and 

 the number of viable seeds each fruit 

 contains, that is, both fruits and seeds 

 may be aborted in processes that are 

 modified or limited by environmental 

 conditions. Investigations on fruit and 

 seed abortion may provide informa- 

 tion which will increase productivity 



of agricultural crops and be crucial to 

 survival of endangered New Hamp- 

 shire species. 



A. C. Mathieson, a marine phy- 

 cologist and former Director of the 

 Jackson Estuarine Laboratory at Adams 

 Point, is an authority on seaweed, spe- 

 cifically Irish Moss (Cro/ic/ruscWspus) 

 which is used both for human food 

 and livestock feed. Between 1974 and 

 1987 Mathieson and his associates and 

 graduate research assistants authored 

 a list of some 45 publications. One of 

 these (MathiesonandE.J.Hehre, 1986] 

 summarized their research findings 

 for the period 1965-1983 in the form of 

 a detailed synopsis of the state's algal 

 flora. More than 200 taxa were recorded 

 including eight new state and/or geo- 

 graphical records. Funding in support 

 of their research has come from the 

 Experiment Station, the UNH Office of 

 Sea-Grant Programs, and the National 

 Oceanic and Atmospheric Adminis- 

 tration (N.O.A.A.].
