S. Satheeshkumar,S. Venkateswaran,R. Suresht suited for the conditions it encounters (Via and Lande 1985; Kawecki and Stearns 1993). However, because most environments change markedly with season, many individuals actually move from one environment to another (i.e., they migrate). Thus, the reaction norm must include many adjustments in morp

Yingjiu Bai,Jehn-Yih Juang,Akihiko Kondoh general seasonal course of migration is endogenously controlled, such as the onset, the temporal pattern, the direction of migration and the seasonal pattern of energy stores. This leads to the conclusion that an endogenous spatiotemporal migration programme guides inexperienced migrants from their

Yingjiu Bai,Jehn-Yih Juang,Akihiko Kondohl features (e.g. Cox 1968; Gaston 1974; Greenberg 1981). Winkler and Leisler (1992) partly overcame this deficit and related skeletal and myological measurements to migration in several passerine and non-passerine groups. Their main findings were: aspect ratio was higher in migrants in all groups st

Rainer Helmig,Martin Emmert,Hussam Shetace and Ollason 1987). In a comprehensive review of optimal migration, Alerstam and Hedenström (1999) discussed theoretical aspects of flight and behavior (e.g., flight speed and power, fuel deposition rates, fuel loads, departure rules) that birds might adopt to maximize their individual fitness.

Groundwater and Subsurface Remediation have been well documented in birds (e.g. Perrins 1970; Verhulst et al. 1995) and shown to be causally related to the timing of breeding (e.g. Verhulst et al. 1995; Brinkhof and Cave 1997). For arctic breeders the window in which breeding can take place is even narrower. Therefore, the capacity of m
