Particle and front tracking in experimental and computational avalanche dynamics [PDF]

Natural Hazards and Earth System Sciences
Understanding particle motion in snow avalanches is crucial for improving the representation of flow dynamics in numerical models. In this study, we develop and apply a general framework for testing and calibrating thickness-integrated flow models using ...

Fourteen simple-sequence repeats newly developed for population genetic studies in Prosopis africana (Fabaceae–Mimosoideae)

BMC Research Notes, 2017
Background There is very limited genetic knowledge in Prosopis africana, an important sub-Saharan multi-purpose tree species. Availability of highly polymorphic genetic markers would be helpful for future genetic work. Findings Leaf samples from 15 trees

An integrated modeling approach for assessing management objectives for mule deer in central British Columbia

Wildlife Society Bulletin, 2017
We used an integrated Bayesian state‐space population model to assess whether management objectives were met before (1995–2003), during (2004–2010), and after (2011–2013) antlerless permits to harvest mule deer (Odocoileus hemionus) were increased in ...
