Some plants can “escape” drought stress by speeding up their life cycles, minimising water loss and allocating more resources to roots when water is available. Over half of the world’s worst weeds are annuals and occur...

Evolution of mating system, life history, and photosynthetic physiology in Clarkia
In the western United States, Clarkia (Onagraceae) taxa vary in mating system, life history, and photosynthetic physiology. Self-fertilizing taxa bloom earlier in the year and have higher rates of photosynthesis than...

Variation in outcrossing and photosynthetic rates in Clarkia reveals independent evolutionary transitions
Adaptive hypotheses to explain the evolution of self-fertilisation in plants are well-characterised, but alternative evolutionary pathways are underexplored. The mating systems and photosynthetic rates of some sister...
Summer dormancy and seasonal growth in California perennial grasses
Superior drought survival is expected to result in reduced productivity and competitive ability, but this expectation has seldom been tested in herbaceous perennial species. Balachowski et al. quantified seasonal...
