Neotropical mangroves compete for pollinators
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

Mastoparan-induced programmed cell death in Chlamydomonas
Under stress-promoting conditions unicellular algae can undergo programmed cell death (PCD), but the mechanisms are poorly understood. Yordanova et al. expose Chlamydomonas reinhardtii to the

Functional pollinators and morph ratio in Narcissus
Heterostyly and related style polymorphisms are good model systems to evaluate the importance of functional pollinators in the maintenance of population variability. Santos-Gally et al.

AGPs in Trithuria reproductive structures
Trithuria is the sole genus of Hydatellaceae, a family of the early-divergent angiosperm lineage Nymphaeales. In order to help determine the early evolution of angiosperm

Sun/shade conditions and seedling recruitment in a cactus
Early life-history stages of cacti can benefit from the facilitative effects of nurse plants that reduce solar radiation and water stress. Miranda-Jácome et al.

Habitat specialization through germination cueing
The importance of regeneration to plant habitat specialization has been poorly studied. ten Brink et al. examine the adaptive association between germination ecology and specialization to

Mechanism of pollinator specificity in Ficus
Pollinator specificity facilitates reproductive isolation among plants, and mechanisms that generate specificity influence species boundaries. Wang et al. use two varieties of an Asian fig tree,

Seasonal and inter-annual bud development in oak species
In trees, bud development is driven by endogenous and exogenous factors such as species and climate, respectively. Alla et al. study bud enlargement and secondary growth

Sterile flowers promote female reproductive success
Large floral displays attract pollinators but can also promote among-flower self-pollination (geitonogamy). Morales et al. assess the effects of the presence of sterile flowers
