Deciphering the biosynthetic pathways of lichen acids
New Phytologist, EarlyView.Summary Depsides and depsidones are polyketide‐derived lichen acids widely distributed in lichen thalli, yet the biosynthetic gene clusters (BGCs) responsible for their production remain poorly understood. To address this gap, we investigated the diversity and evolutionary relationships of polyketide BGCs in lichens.

Genetic relationships between Woodland and Barren ground caribou
Rangifer, 1996 Abstract: The genetic relationships between woodland and barren ground caribou herds are being investigated using both mitochondrial and nuclear D N A . D N A sequence variation i n the most variable region (the D l o o p region) o f mitochondrial D N A indicate the woodland caribou from Newfoundland, Ontario, Alberta, and Brit ish Co lumbia are ...

New Phytologist, EarlyView.Summary Soil nutrients and vertebrate herbivory are key ecological factors with opposite and interactive effects on grassland plant traits and biomass. Partitioning trait changes into species turnover and intraspecific change provides a mechanistic linkage between trait shifts and biomass responses.

Movement pathways and habitat selection by woodland caribou during spring migration
Rangifer, 2005 Woodland caribou (Rangifer tarandus caribou) are a threatened species throughout Canada. Special management is therefore required to ensure habitat needs are met, particularly because much of their current distribution is heavily influenced by resource ...

Restoration Ecology, EarlyView.Abstract Introduction Global interest in, and funding for, ecosystem restoration is growing in the face of ongoing ecosystem degradation. The role and inclusion of Indigenous Peoples and local communities (IP&LCs) have not been given sufficient attention in ecosystem restoration. Objective The objective of this research is to apply the lessons from the
