Critical thinking (CT) underpins the analytical and systems-thinking capacities needed for effective conservation in the 21st century but is seldom adequately fostered in most postsecondary courses and programs. Many instructors fear that devoting ti

We examined the variation in woody plant species composition, regeneration and biodiversity in relation to topographic heterogeneity, specifically catena shape (V and Λ) and slope position (summit, shoulder, back slope, foot slope and toe slope). Al

Non-native Phragmites australis poses an increasing threat to salt marsh eco-systems in the eastern United States. Multiple factors affect P. australis spread, including reduced salinity and nitrogen runoff. Methods for measuring expansion, such as f

Understanding the factors that determine the distribution of understory plants is important because they represent the largest component of temperate forest plant diversity. We examined the influence of topographic gradients on the distribution of un

Most salt marshes are dominated by graminoids, but patches dominated by a diverse assemblage of perennial forbs, known as forb pannes, occur on marshes in north temperate areas. These pannes and their associated species diversity appear to be highly

Plants with higher glutamine synthetase (GS) activity in photosynthetic tissues than below-ground structures (high leaf:root (L:R) GS activity) show growth advantages over plants with a low L:R GS activity ratio. The benefits of a high L:R GS activit

New England high salt marsh primary productivity is limited by N, but variation in plant N availability across salt marsh vegetation zones has not been quantified. To investigate this, we measured in situ net N mineralization rates throughout the gro

The long-term (5-yr) responses of plant absolute abundance and species diversity to N, P, and N+P fertilization were investigated in two sedge-dominated alpine plant communities that differed in soil resource availability but not in macroclimate: a r

A nutrient amendment experiment was conducted for two growing seasons in two alpine tundra communities to test the hypotheses that: (1) primary production is limited by nutrient availability, and (2) physiological and developmental constraints act to

Physiological and growth measurements were made on forbs and graminoids following additions of water and N+water in a graminoid-dominated dry meadow and a forb-dominated moist meadow, to determine if the community-level response was related to differ
