Sentence examples for energetically constrained from inspiring English sources

For our purposes here, we define an ecological path to zero growth as that in which individuals become energetically constrained to the point where birth rates equal death rates.

We expected that the treated birds, in both experiments, would change the length of their incubation bouts, if biparental incubation-scheduling is energetically constrained.

First, this level may simply be a by-product of the resources left to females directly after egg production, so that females are energetically constrained in their level of care [ 1].

Our finding revises previously published work (Cresswell et al. 2003), which suggested (using experimental nest insulation) that incubation-scheduling in semipalmated sandpipers was energetically constrained and driven by the energy reserves of the incubating parent.

Second, our findings suggest that biparental incubation-scheduling is less energetically constrained than uniparental incubation (e.g., Aldrich and Raveling 1983; Bryan and Bryant 1999; Reid et al. 1999; Cresswell et al. 2004; Ardia et al. 2009).

The first study conducted in the high Arctic on semipalmated sandpipers, Calidris pusilla reported that an experimental reduction in the energetic demands of incubation (achieved with a polystyrene insulation of the nest cup) prolonged incubation bouts and concluded that biparental incubation-scheduling is energetically constrained (Cresswell et al. 2003).

Hence, in the PKN case, this analysis provides the first indication that a natural, or energetically optimal, spacing exists when multiple height constrained hydraulic fractures are simultaneously propagated.

He began and ended the performance energetically enough, but his movements were seriously constrained for much of the evening: He wasn't cueing and exhorting the players with his usual verve.
