Pine species play important role in Brazilian economy for solid wood and resin production. However, information about the effect of fertilization on wood and resin production is scarce. Thus, to investigate the relationship between different fertilization regimes on wood/resin productivity further, this paper analyzes the effects of two fertilizing ...

Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.

Neutral effects of low‐intensity dog training on northern bobwhite vital rates
Indirect effects of hunting can lead to changes in population dynamics, which can be caused by trait‐mediated effects such as, but not limited to, changes in behavior, reproduction, and physiological responses. Our understanding of the effects of activities associated with hunting such as dog training may incur trait‐mediated effects, and ultimately ...

From beginning to end: the synecology of tree‐killing bark beetles, fungi, and trees
ABSTRACT Over a century of research has revealed an amazing complexity of behaviours and physiological adaptations that allow tiny bark beetles to overcome large trees, sometimes resulting in outbreaks that kill millions of trees. Turning a tree into a home and successfully raising offspring involves constant interactions among the beetles, the tree ...
