Phenology
- Effects of temperature on the timing of breeding and molt transitions in house finches
Summary: Experimental manipulations in male house finches indicate that elevated temperature has no direct effect on the timing of reproductive preparations, but does influence the transition from breeding to molt.
- Metabolome dynamics of diapause in the butterfly Pieris napi: distinguishing maintenance, termination and post-diapause phases
Highlighted Article: Diapause in a temperate butterfly is associated with a highly dynamic metabolome, and its termination, once initiated by cold, is associated with temperature-independent changes in profiles of several key metabolites.
- Effects of a social cue on reproductive development and pre-alternate molt in seasonally breeding migrant and resident female songbirds (Zonotrichia leucophrys)
Highlighted Article: Migrant and resident birds exhibit differences in reproductive development consistent with adaptive specialization in the use of photoperiodic cues, but not social cues, to regulate reproductive development.
- Divergence of the diapause transcriptome in apple maggot flies: winter regulation and post-winter transcriptional repression
Summary: Transcriptomics reveals that summer emergence timing of flies is regulated during winter, while initial transcriptional responses to post-winter warming are largely suppressed.
- Transcriptome profiling reveals mechanisms for the evolution of insect seasonality
Summary: Evolutionary changes to the timing of diapause will be key for insects to adapt to a globally warming climate; putative loci responsible for timing shifts are identified.
