Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review

open access: yesSystems Engineering, EarlyView.
ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to

Adaptive harvesting of two trophic levels stabilises predator–prey dynamics. Simulations with Eurasian lynx and European roe deer

open access: yesWildlife Biology, EarlyView.
Europe has seen the recovery of many species of wild herbivores, which are now widespread across much of the continent. In addition, large carnivores are also recolonising many European countries. Most ungulates are managed through hunting, but natural predation can also have a significant influence in many areas.

Abundance, trends, and challenges facing mountain goats throughout their North American distribution

open access: yesWildlife Society Bulletin, EarlyView.
Our survey of states and provinces revealed that 13% of native mountain goat populations increased during the past 10 years, whereas 38% declined. For introduced populations, increases were roughly equal to declines. Rates of change were positively associated with being introduced or pioneering, and negatively associated with heavy snow, and, to a ...
