Consider alternative designs and trait integration level for better ecosystem analysis
To fully understand how an ecosystem fits together, consider how alternate designs may achieve the same end. More

Drivers of intraspecific variation in seed dispersal are diverse and pervasive
Intraspecific variation in the quantity and quality of seed dispersal has important ecological and evolutionary consequences, yet it is generally ignored in favour of focussing on population mean values. As a result, there are large gaps in our understanding of intraspecific variation in seed dispersal traits. We do not know how pervasive detectable variation in […] More

Resprouting potential of rhizome fragments in an invasive aquatic plant
Non-native aquatic Ludwigia species from a polyploid complex are among the world’s most problematic invasive plants. A new paper in AoBP finds out why. More

Even for specialists, floral morphology is influenced by both pollinators and climate
Climate can indirectly affect floral morphology within a species by affecting what pollinators will visit those flowers across its range. More

Effect of simulated warming on Leymus chinensis grasslands of northeast China
Mean global temperatures have risen by almost 1°C since 1850 and are predicted to continue to rise through to the end of the century. Understanding how grasses are affected by a long-term increase in temperature is crucial to predicting the future impacts of climate change. Grasslands occupy over 3.5 billion hectares of land and store […] More

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 or increase their biomass, to tolerate or resist stress, and to pass genetic material to new generations. Yet the three central resource allocation pathways of growth, defence and reproduction have […] More

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? More

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 respiration accounting for about half of this flux. As a result, terrestrial biosphere models are highly sensitive to changes in plant respiratory processes. The thermal acclimation response of plant respiration […] More

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 photosynthesize and transpire puts trees at risk of damaging their hydraulic conductivity and overall health. With growing seasons expected to lengthen with climate change in the northwestern USA, the […] More

How important is meat to a curious carnivorous plant?
Drosophyllum lusitanicum, also known as the Portuguese sundew or dewy pine, is unusual even for carnivorous plants in that it lives in dry environments. Typically, carnivorous plants live in nutrient-poor wetlands, so does it really gain much from carnivory? More

The mountains are getting warmer, and willow colonies are shrinking
Salix herbacea, as other arctic-alpine species, likely found a refuge from the Ice Age in the Apennines. As the climate changed around them, the trees survived in a fragmenting population. This fragmentation has genetic consequences. More
