The '''Louis Calder Center''' is Fordham_University's biological field station. The Calder Center is a protected forest preserve located 30 miles north of New_York_City in Armonk,_New_York, and is the only full-time ecological research field station in the New_York_metropolitan_area. == History == The Louis Calder Center was founded in 1967 when Louis_Calder donated his 113-acre estate to Fordham University. Buildings have since been constructed, renovated, and modernised. == Buildings == The Louis Calder Center consists of 19 buildings including: *Calder Hall - A 27-room stone mansion which houses seminar rooms, a library, herbarium, insect collection, guest rooms, kitchen, and dining room. *McCarthy Laboratories - a building where a great amount of the analysis of samples is carried out. The lab includes growth chambers, a Nutrient Autoanalyzer, Gas_chromatograph, HPLC, Carbon-Nitrogen Analyzer, Fluorescence and Phase_microscopes, Spectrophotometres, Autoclaves, electronic balances, Refrigerators, Centrifuges, and other scientific equipment. *Greenhouses *Lakeside Lodge *Routh House == Calder Lake == Calder Lake is a 4 hectacre mesoeutrophic lake located within the Louis Clalder Center. The lake bottom is more than half covered by a submeresed Macrophyte community, including ''Vallisneria_americana, Elodea_canadensis, Potamogeton_amplifolius'', and ''Najas_flexilis''. Since Calder Lake is relatively small, the surrounding Flora (including ''Quercus_rubra, Quercus_prinus, Acer_rubrum, Fagus_grandifolia'', and ''Cornus_florida'') plays a significant role in its ecology, as falling leaves add nutrients to the water. The production rates of Bacteria and larger Phytoplankton in the Lake are limited by the supply of inorganic Phosphorus. Dissolved organic carbon exists between 4-6 mg C/L in the lake. ==External links== *Official Website Category:Fordham_University Category:Westchester_County,_New_York
