IMPROVING CONSERVATION EFFORTS THROUGH A BETTER UNDERSTANDING OF FOREST ELEPHANT ECOLOGY, THE IMPACTS OF THREATS ON ELEPHANTS AND FRESHWATER FISHERIES IN NORTHERN SEPTEMBER 2016 ROGER PATRICK BOUNDJA, B.Sc. FORESTRY, MARIEN NGOUABI UNIVERSITY, BRAZZAVILLE MSc. UNIVERSITY OF CAPE TOWN PhD. UNIVERSITY OF MASSACHUSETTS AMHERST Directed by: Professor Curtice R. Griffin Catch data, including fish numbers, length-weight were collected during a multi-mesh Gillnet fisheries-independent survey in 2007-2008, and fisheries-dependent mixed gear surveys in 2009-2010 and 2015 across 400km stretch of the Sangha River located in the Sangha Tri-National. Overall, very high species richness (Chao 2 mean=250, SD=16.15) and diversity index (Simpson Inverse …
Moss Composition Affects Seedling Density Of Western Hemlock And Sitka Spruce, Katy E. Maleta Ms.
Moss Composition Affects Seedling Density Of Western Hemlock And Sitka Spruce, Katy E. Maleta Ms.
Summer Research
Nurse logs at the Hoh National Forest represent a clear understanding of how important habitat heterogeneity is in old growth forests. Looking down a nurse log, you will find various moss species and debris along with seedlings being assisted in germination. By observation, there is an effect of moss composition on seedling density. We found that when moss depth increase, seedling density decreases. We also found that where the moss was the most thick, the moss species that was present was Hylocomium Splendens (Step Moss). We also found that when moss depth decreased, seedling density increased and the moss species …
Effects Of Mountaintop Removal Mining On Population Dynamics Of Stream Salamanders, Sara B. Freytag
Effects Of Mountaintop Removal Mining On Population Dynamics Of Stream Salamanders, Sara B. Freytag
Theses and Dissertations--Forestry and Natural Resources
Mountaintop removal mining (MTR) is a notorious stressor of stream ecosystems in the Central Appalachians. Valley fills (VF) lead to reduced occupancy, abundance, and species richness of stream salamanders. Multiple factors may be responsible for these reductions, but specifically habitat fragmentation and degradation may reduce colonization rates and increase local extinction rates. From 2013-2015, repeated counts of salamanders were conducted in stream reaches impacted by MTR/VF and compared to counts in reference reaches to answer the question: do stream salamander population dynamics differ between stream reaches impacted by MTR/VF and reference stream reaches? I also investigated dynamics of stream habitat …
