Genetic connectivity is crucial in rapidly changing environments as it allows exchange and dispersal of adaptive genes among plant populations.

Co-flowering species can either compete for pollination services, have no effect on one another or facilitate one another by attracting more pollinators. Landry studies two mangrove species with overlapping flowering phenologies, Avicennia germinans and Laguncularia racemosa, in southern Florida and finds that when they co-flower A. germinans out-competes L. racemosa for pollinators. Hermaphrodites of L. racemosa [...]
Modelling phosphorus and reproductive phenology Delayed reproduction in soils with low phosphorus (P) availability is common among annuals, in contrast to the accelerated reproduction typical of other low-nutrient environments. Nord et al. present a two-resource dynamic allocation model of plant growth and reproduction for Arabidopsis thaliana that incorporates growth, respiration, and carbon and P acquisition [...]
Effects of cotyledon damage on fitness in <i>Medicago</i> Damage to cotyledons can have significant effects on subsequent plant growth and reproduction. Studying the annual species Medicago lupulina, Zhang et al. examine the mechanisms linking cotyledon damage and fitness, as measured by growth and reproductive traits. They show how a network of indirect mechanisms links cotyledon damage [...]
