Changing Land-Use From Pinus Elliottii To Eucalyptus Bentamii In Southwest Louisiana Affects Understory Vegetation Richness, Diversity, And Functional Diversity Patterns, Andrea De Stefano
Changing Land-Use From Pinus Elliottii To Eucalyptus Bentamii In Southwest Louisiana Affects Understory Vegetation Richness, Diversity, And Functional Diversity Patterns, Andrea De Stefano
LSU Doctoral Dissertations
In the Western Gulf region of the United States cold-tolerant eucalyptus have been explored as pulpwood feedstock. However, non-native plantations may alter understory species diversity, modifying environmental conditions and soil characteristics. Few studies have compared eucalyptus plantations with other ecosystems to understand the impacts of converting these land uses on understory vegetation in the United States. Three plantations were selected: (1) slash pine (Pinus elliottii) established in 2008, (2) slash pine established in 2013, and (3) and Camden white gum (Eucalyptus benthamii) established in 2013. The objectives of this study were to: (1) investigate potential changes …

The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are measured. Here, we use a pest-control database encompassing 132 studies and 6,759 sites worldwide to model natural enemy and pest abundances, predation rates, and crop …

Murids to have more than 1300 species globally, forming the largest mammal group. Murids are found nearly everywhere in the world, though many subfamilies have narrower ranges. Murids are not found in Antarctica and many oceanic islands. Five National Parks from Northern areas of Pakistan were physically surveyed. The parks were studied at different times. Dhirkot National Park (DNP) in February 2008, Banjosa National Park (BJNP) from May to June 2009, Pir Lasura National Park (PLNP) from June to July 2009 and Pir Chanasi National Park (PCNP) from April to May 2010. A total of 6 species belonging to the …
The 2011 Climate Regime Shift: Seabed Taxon Monitoring Identifies Regimes, Jeff Marliave, Donna Gibbs, Laura Borden

Monitoring of biodiversity may sometimes reflect human impacts on ecosystems, but analysis of biodiversity needs to account for naturally occurring trends as well. Biodiversity may provide more accurate definition of climate regime shifts than do physical oceanographic data, Using search programs for a long-term SCUBA taxonomic database (3865 dives) for Strait of Georgia seabed sites, 1,077 taxa were screened to select 171 rare or highly abundant taxa and to present the data according to climate regime categories. Ocean Niño Index climate regime shifts are defined here as the year of the end of the first La Niña closely paired with …
The Citizen Scientific Method: Tapping A Human Natural Resource In Ecosystem Restoration, Bianca S. Perla, Greg Rabourn
The Citizen Scientific Method: Tapping A Human Natural Resource In Ecosystem Restoration, Bianca S. Perla, Greg Rabourn
Salish Sea Ecosystem Conference
Citizen science forms a nexus point between research and education, between social outreach and project implementation, and between local knowledge (traditional ecological knowledge) and scientific knowledge. For this reason, citizen science can be a valuable tool to integrate the many different players in ecosystem restoration projects and help projects succeed. Citizen science can increase civic engagement in ecosystem restoration, fill in data gaps, and help make adaptive ecosystem management a real community process. However, significant challenges often impede the ability of citizen science projects to reach their full potential. Here, we discuss trends and insights gained through examining three citizen …

Prioritizing Seagrass Meadows For Biodiversity Conservation Based On Landscape Connectivity, John Cristiani, Mary O'Connor
Salish Sea Ecosystem Conference
The spatial configuration of habitat and biological dispersal traits affect how organisms move across heterogenous landscapes, connecting populations and maintaining biodiversity. Quantifying this connectivity is critical to understanding and managing marine biodiversity. Despite its importance, for most regions, we lack estimates of connectivity and consideration of how habitat loss or restoration scenarios change connectivity and thereby affect diversity. We simulated dispersal and connectivity in several habitat change scenarios for seagrass habitats in the Salish Sea of British Columbia and Washington. We used a spatially explicit biophysical model to track passive larval dispersal in oceanographic currents for select life history traits. …
