Resource allocation trade-offs in a mast-seeding conifer
Three key functions are required for the long-term persistence of tree populations in a landscape. Broadly speaking, trees must acquire and allocate resources to maintain

Seedling responses to salinity of 26 Neotropical tree species
How will coastal ecosystems change when some seedling can tolerate rising tides, and others cannot?

Risk-takers and risk-avoiders: germination sensitivity to water stress in an arid zone with unpredictable rainfall
How much water does it take to turn an arid land into a hotbed of new life?

Can insights from invasion ecology promote benefits from root mutualisms in plant production?
Ramoneda et al. propose specific experimental approaches to utilize the wild ancestors of crops to determine whether crop domestication compromised the benefits derived from root microbial symbioses or not.
Ecosystems
Thermal acclimation of plant respiration is tissue type specific
Carbon released from the land surface is one of the largest fluxes of carbon dioxide (CO2) between the atmosphere and the Earth’s surface, with plant

Cold stress tolerance genes of the wild cotton species Gossypium thurberi
Low temperatures at the start of the growing season can impair the productivity of crop species. Chilling (0 – 20°C) and freezing (< 0°C) both
Growth & Development
Stem and leaf growth rates define the leaf size vs. number trade-off
In trees, the trade-off between leaf number and individual leaf size on current year shoots (twigs) is crucial to light interception. This relationship has consequences

Drought tolerance strategies of conifer species in the northwestern US
As trees photosynthesize, using carbon from the atmosphere to grow and store energy, they also lose water to the air (transpire). During a drought, continuing to

Ovule and seed production patterns in relation to flower size and floral symmetry
Animal pollinated flowers show two types of floral symmetry, actinomorphy (radial symmetry) with several planes of symmetry or zygomorphy (bilateral symmetry) with just one symmetry plane.

Effects of deer exclusion on plant recovery in dune ecosystems after a severe coastal storm
The dunes of barrier islands erode during storm events but they also prevent damage to inland ecosystems. For these dunes to function in this way, vegetation

The contrasting effects of climate change-induced drought on three temperate tree species
Climate change-induced drought has already contributed to increased plant mortality around the globe, including in forest ecosystems. Drought events are projected to become even more
