Toward an Evolved Concept of Landrace
The term "landrace" has generally been defined as a cultivated, genetically heterogeneous variety that has evolved in a certain ecogeographical area and is therefore adapted to the edaphic and climatic conditions and to its traditional management and uses. Despite being considered by many to be inalterable, landraces have been and are in a constant state of evolution as a result of natural and ...
متن کاملToward an Empirical Concept of Group
What is to be made of the idea of “the group”? Is it a collection of personsliterally a gathering together? Or, is it something more-a real presence over and above its members?

A major problem that transcends the boundaries of biological disciplines is reconciliation of phenotypic change and stability. On the one hand, individual organisms are extraordinarily plastic, responding to life-stage transitions, seasonal cues and environmental change. Some of these changes are permanent and some are reversible, occurring thousands of times during a single lifetime. On the ot...
متن کاملToward an Integrative Concept of Control of Total Body Sodium.
Total body sodium (TBSodium) is a major determinant of body water and arterial pressure. Several observations, in particular that of a "sodium memory," indicate that TBSodium is a controlled variable. Various regulatory elements are involved, e.g., the renin-angiotensin-aldosterone system, atrial receptors, and renal arterial pressure. Balance studies in dogs provide new insights into their con...
متن کاملToward an Action-Concept Model of Stimulus-Response Compatibility
This chapter highlights the importance of the problem of action coding, that is, the cognitive representation of action, for theories of S-R compatibility. An action-concept model of S-R compatibility is presented, based on considerations of Lotze and HarleB on the emergence of voluntary action. It assumes that the cognitive code of any perceivable, movement-contingent event--hence, action effe...
