The invasive spotted lanternfly (SLF) is a threat to multiple agricultural industries. In our new publication at www.mdpi.com/3429276, we present a #model that predicts the seasonal development ( #phenology) of the #SLF in areas that are climatically suitable for #establishment. #ipm #invasivepest

Measuring invasive spread requires distinguishing jump events from diffusion. Check out this #Rstats package that does it! For #spottedlanternfly, diffusive spread is constant, but jump spread is accelerating 🌐 neobiota.pensoft.net/article/1473... @neobiota.pensoft.net

For those who have taken sabbaticals: Did you set up an automatic email reply? I officially started sabbatical July 1, and have already received multiple emails I'd like an automatic response for. Any recommendations on wording?

Summarise Continuous and Categorical Variables, Check for Duplicates and Missing Data
The sumvar package quickly explores continuous and categorical variables. sumvar aims to bring the ease and simplicity of the "sum" and "tab" functions from stata, to R.

Girls born only a few days apart, but on either side of the starting-primary-school cut off date, have drastically different math scores. Not so for boys.

We all know that prairie dogs are keystone species, and they're super cute when they yell and all run away, but did you know that birds also hear their calls and fly away when predators are near. Check out this new paper #ecology 🌐
