Data from: StomataCounter: a neural network for automatic stomata identification and counting

Karl C. Fetter, Sven Eberhardt, Rich S. Barclay, Scott Wing & Stephen R. Keller
Stomata regulate important physiological processes in plants and are often phenotyped by researchers in diverse fields of plant biology. Currently, there are no user friendly, fully-automated methods to perform the task of identifying and counting stomata, and stomata density is generally estimated by manually counting stomata. We introduce StomataCounter, an automated stomata counting system using a deep convolutional neural network to identify stomata in a variety of different microscopic images. We use a human-in-the-loop approach...

Data from: Evidence for arrested succession in a liana‐infested Amazonian forest

1. Empirical evidence and modelling both suggest that global changes may lead to an increased dominance of lianas, and thus to an increased prevalence of liana-infested forest formations in tropical forests. The implications for tropical forest structure and the carbon cycle remain poorly understood. 2. We studied the ecological processes underpinning the structure and dynamics of a liana-infested forest in French Guiana, using a combination of long-term surveys (tree, liana, seedling and litterfall), soil chemical...

Data from: Genome-wide association analysis of stalk biomass and anatomical traits in maize

Background: Maize stover is an important source of crop residues and a promising sustainable energy source in the United States. Stalk is the main component of stover, representing about half of stover dry weight. Characterization of genetic determinants of stalk traits provide a foundation to optimize maize stover as a biofuel feedstock. We investigated maize natural genetic variation in genome-wide association studies (GWAS) to detect candidate genes associated with traits related to stalk biomass (stalk...

Data from: Polyandry and polygyny in a social rodent: an integrative perspective based on social organization, copulations, and genetics

John L. Hoogland, Regina Trott & Stephen R. Keller
Animal mating systems have fascinated biologists for thousands of years. Ways to describe amating systeminclude determining social organization, observing copulations, or using genetics to assign parentage. Social organization can be difficult to quantify, however, documentation of copulations is often challenging, many copulations do not produce offspring, and genetic variation is sometimes minimal. Here we use data from a 7-year study of wild white-tailed prairie dogs (WTPDs, Cynomys leucurus) living in Colorado USA to estimate the...
