Student mentored by Forest Service scientist receives honor for research poster

Year: 2017

A student mentored by a Forest Service scientist earned the Best Undergraduate Poster Award for research showing that it is the extent of root symbiotic fungi, not root length, that determines nutrient uptake by tree roots.

Temperate and Boreal Fungi Less Sensitive to Climate Change than Tropical Fungi

Year: 2015

Beneficial fungi that help tree roots obtain nutrients from soil are less sensitive to climate in temperate and boreal forests than in tropical forests, but the same is true for root pathogens.

Opening the Forest Canopy Slows Leaf Decomposition and Nutrient Cycling

Year: 2015

Forest canopies are opened by thinning, logging operations, and storms. Results of a simulated hurricane experiment showed canopy opening had the greatest effect in slowing leaf decomposition and nutrient release. Losses of nitrogen to ground water only occurred when the limbs and leaves were transferred from the canopy to the forest floor.

Leaf decomposition baskets hold apart the leaf litter layers in a hurricane simulation experiment in the Luquillo Experimental Forest of Puerto Rico. Leaf decomposition and nutrient cycling were studied in decomposition baskets with screens placed between layers to measure decay rates, nutrient movement between layers, phosphorus retention, and number of mushroom fungal connections between litter layers. Placement of green ‘hurricane' leaves (top layer) over freshly fallen senesced leaves (middle layer) and the forest floor (bottom layer) protected the underlying litter and decay fungi from drying when the canopy was opened by trimming tree branches.

Leaves Left on the Ground After Storm Damage or Logging Lead to Faster Forest Recovery

Year: 2014

Opening a forest, whether by storm damage, tree harvesting or thinning, dries the forest floor and reduces the ability of the litter layer to retain mineral nutrients needed for tree growth. Forest Service scientists and partners found that allowing green leaves to remain on the forest floor in a wet subtropical forest in Puerto Rico compensated for and buffered the litter layer below from the negative effects of canopy opening, allowing the forest to retain nutrients and the tree trunks to grow faster.
