Резюме	Starch grain analysis recovers and identifies microscopic starch granules preserved on archaeological artifacts and in dental calculus to reconstruct ancient plant use. Many economically important plants — tubers, roots, seeds, and cereals — store energy as starch in granules whose size, shape, hilum position, and surface features can be diagnostic of a plant family, genus, or even species. Because starch can lodge in the use-wear pits of grinding stones, adhere to pottery, settle into sediments, and become trapped in calcified dental plaque, it survives where charred macroremains do not, opening a window onto plants such as manioc, potato, and banana that rarely carbonize. Under polarized light, intact starch shows a characteristic birefringent extinction cross, and identification proceeds by morphometric comparison to modern reference granules, following procedures consolidated in Pearsall's paleoethnobotanical handbook.	Site catchment analysis models a settlement's economy by delimiting the territory that its inhabitants could realistically exploit and inventorying the resources within it. Introduced by Claudio Vita-Finzi and Eric Higgs in their 1970 study of the Mount Carmel area, the method rests on the premise that the cost of moving to and from a site falls off sharply with distance, so most subsistence activity occurs within a limited radius. By drawing a catchment — classically the area within one or two hours' walk — and measuring how much of it is arable land, grazing, water, lithic sources, or wild biota, the analyst characterizes whether a site is oriented toward farming, herding, hunting, or gathering. Modern practice replaces simple circles with terrain-sensitive least-cost territories computed in a Geographical Information System, as set out by Conolly and Lake.
