New technologies may enhance management by enabling quantitative testing of assumptions of vegetation response to climate and management. State-and-transition simulation models can keep track of interactions that are too complicated for us to comprehend using only conceptual models. This tool takes conceptual state-and-transition models to the next level, fostering greater communication and dialogue with stakeholders.
Forest managers are increasingly focused on promoting or maintaining forest structural complexity, including the heterogeneity of forest structures within stands. However, many of the forest growth models commonly used by forest managers assume that stands are structurally homogeneous. Therefore, using these forest models to project the development of structurally complex stands may provide inaccurate results.
Wildfires can drastically alter belowground processes such as organic matter (OM) decomposition.
Rocky Mountain tailed frogs (Ascaphus montanus) were thought to exist exclusively in two tributaries of Warm Springs Creek watershed - Storm Lake Creek and Twin Lakes Creek, based on opportunistic observations of tailed frogs during fish sampling rather than formal basin-wide sampling for frogs.
Podosphaera pannosa is the causal agent of powdery mildew on eucalypt in Brazil. This powdery mildew disease is important in nurseries causing leaf and shoot distortion, shoot discoloration and reduction in growth, which decreases mini‐cutting production.
In Wisconsin, as in other states, management goals sometimes include restoration of historical forest conditions, which may prepare forests to be more compatible with future climates, disturbances such as drought and fire, and forest health threats.
Plant invasions can affect fuel characteristics, fire behavior, and fire regimes resulting in invasive plant-fire cycles and alternative, self-perpetuating states that can be difficult, if not impossible, to reverse.
For millennia, natural disturbance regimes, including anthropogenic fire and hunting practices, have led to forest regeneration patterns that created a diversity of forest lands across the USA. But dramatic changes in climates, invasive species, and human population, and land use have created novel disturbance regimes that are causing challenges to securing desired natural regeneration.
Four new species of Enlinia Aldrich are described from Chile: Enlinia biobio n. sp., Enlinia chilensis n. sp., Enlinia enormis n. sp., and Enlinia isoloba n. sp. These specimens were collected during a 2013 invertebrate survey in sclerophyll and Valdivian temperate rain forest habitats of the central and southern Chilean Andes. The only other species of Enlinia recorded from Chile is E. atrata (Van Duzee).
Two new species of the long-legged fly genus Hurleyella Runyon & Robinson, 2010 are described and illustrated: Hurleyella belizensis sp. nov. from Belize and Hurleyella salina sp. nov. from alkali areas of the Northern Rockies of the USA (Idaho, Montana, Wyoming). The discovery of these new species greatly extends the known distribution of Hurleyella northward in the Nearctic and southward into the Neotropics.
