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 or increase their biomass, to tolerate or resist...

Do lianas spend fewer resources on roots for support than other plants?
If a plant can lean on something else, does it really need to invest so much in its roots for support? Could resources usually used for roots be redirected to stems and leaves? In a new paper, Tomasz Wyka and colleagues...

Presence of fruits decreases probability of retaining flowers in a sequentially flowering plant
Both intrinsic and extrinsic plant processes affect the fate of flowers along an inflorescence in sequentially flowering plants. In a study recently published in AoB PLANTS, Jadeja & Tenhumberg investigated...
Carbohydrate metabolism and androdioecy maintenance in Tapiscia sinensis
Fruit ripening overlaps with flowering, leading to a severe reproductive burden on the hermaphroditic individuals.

Intra-specific variation in Arabidopsis functional strategies
Considerable intra-specific variation in functional strategies can occur within a single plant species. C-S-R theory was developed to classify functional strategies (competitive, stress tolerant, ruderal) in different...
With fronds like these… foliar dimorphism and reproduction in ferns
Ferns use their leaves for both reproduction and carbon fixation. How do they manage to use one organ to tackle two very different jobs?
Carbon stores for spring growth in evergreen vs. deciduous species
Deciduous species must rely on stored reserves in stems and roots for the initiation of new season springtime growth. So perhaps evergreen species that can photosynthesize year-round rely more on leaf photosynthate to...

Floral longevity and autonomous selfing in Collinsia
Under drought stress, cross-pollination early in floral lifespan of Collinsia reduces floral longevity, but excess soil moisture does not extend longevity.
The cost of hosting ants
Hosting ants confers effective protection against herbivores, and swollen, hollow stems functioning as domatia have evolved many times in plants. Blatrix et al. study the allometry of stem secondary growth in Leonardoxa...
Phenology and resource allocation in Ruellia
In plants that produce both closed, obligatory self-pollinated (cleistogamous) and open, potentially out-crossed (chasmogamous) flowers, suboptimal conditions typically favour production of cleistogamous flowers...
CO2 effects on reproduction versus vegetative growth
Increased atmospheric CO2 concentrations may affect competition for resources between reproduction and shoot growth in forest species. Han et al. examine mature beech (Fagus sylvatica) trees in masting and non-masting...
Patterns of resource allocation in a dioecious species
Patterns of resource allocation in a dioecious species Resource allocation between vegetative and reproductive growth will vary over time, and dioecious species may also adopt different strategies for allocation between...
