Multilevel Factorial Experiments for Developing Behavioral Interventions: Power, Sample Size, and Resource Considerations

TL;DR: The results suggest that multilevel, multifactor experiments are feasible for factor-screening purposes because of the economical properties of complete and fractional factorial experimental designs.

Early piglet mortality in loose-housed sows related to sow and piglet behaviour and to the progress of parturition

TL;DR: In this article, the authors identify characteristics of sow behaviour and parturition related to early piglet mortality in loose-housed farrowing sows, and use a Graphical Chain Model (GCM) to model the relationships between perinatal behaviour, periparturient individual conditions (time of day of parture, rectal temperature 1-3 days postpartum) and causes of early Piglet mortality.

Lipidome as a predictive tool in progression to type 2 diabetes in Finnish men

TL;DR: It is indicated that a lipid signature characteristic of type 2 diabetes mellitus is present years before the diagnosis and improves prediction of progression to T2DM.

Landscape composition influences roe deer habitat selection at both home range and landscape scales

TL;DR: This paper investigated behavioural plasticity in habitat selection of roe deer in relation to variable habitat availability across a heterogeneous agricultural landscape at the home range and landscape scales, and found no functional response for this habitat, i.e. no shift in habitats selection with changing habitat availability, possibly due to the presence of hedgerows which were increasingly selected as woodlands were less abundant.

Age, competition, disturbance and elevation effects on tree and stand growth response of primary Picea abies forest to climate

TL;DR: The results suggest that although an increase in temperature might enhance growth at high elevations, it may also induce growth declines due to drought stress at lower Elevations, particularly for old trees or trees growing under high levels of competition, which may increase their vulnerability to disturbances.
