William (Tam) Salter is a Postdoctoral Research Associate in the School of Life and Environmental Sciences and Sydney Institute of Agriculture at the University of Sydney. He has a bachelor degree in Ecological Science (Hons) from the University of Edinburgh and a PhD in plant ecophysiology from the University of Sydney. Tam is interested in the identification and elucidation of plant traits that could be useful for ecosystem resilience and future food security under global environmental change. He also has an active interest in effective scientific communication.

Continuous variation in herkogamy in Mediterranean honeysuckle populations
Herkogamy, the spatial separation of sex organs in hermaphroditic plants, is thought to have evolved to reduce self-pollination and inbreeding within a population. Yet there has been little evidence to support these hypotheses. Much work in this field has focussed on heterostyly, in which two or three distinct and reciprocal herkogamy morphs are found in […] More

Gene copy number is associated with phytochemistry in Cannabis sativa
THCA and CBDA were thought to have a simple mode of inheritance; however, a recent study by Vergara et al. describes that in fact multiple gene copies are involved in their production. More

Arabidopsis halleri: a model system for studying population differentiation and local adaptation
Whilst studies on Arabidopsis thaliana have generally been highly molecular and/or genetic in nature, most studies using A. halleri have addressed adaptation and variation in adaptive traits in the species’ natural habitat. More

tealeaves: an R package for modelling leaf temperature using energy budgets
Plants are able to grow, survive and reproduce under a wide range of temperatures. Examples of plants that thrive in temperature extremes include cushion plants in alpine ecosystems that grow close to the ground to stay warm and desert plants that have decreased absorptance to stay cool. Other plants keep their stomata open to dissipate […] 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

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
