Vegetation Dieback In The Mississippi River Delta Triggered By Acute Drought And Chronic Relative Sea-Level Rise, Tracy Elsey-Quirk, Austin Lynn, Michael Derek Jacobs, Rodrigo Diaz, James T Cronin, Lixia Wang, Haosheng Huang, Dubravko Justic
Vegetation Dieback In The Mississippi River Delta Triggered By Acute Drought And Chronic Relative Sea-Level Rise, Tracy Elsey-Quirk, Austin Lynn, Michael Derek Jacobs, Rodrigo Diaz, James T Cronin, Lixia Wang, Haosheng Huang, Dubravko Justic
Journal Articles
Vegetation dieback and recovery may be dependent on the interplay between infrequent acute disturbances and underlying chronic stresses. Coastal wetlands are vulnerable to the chronic stress of sea-level rise, which may affect their susceptibility to acute disturbance events. Here, we show that a large-scale vegetation dieback in the Mississippi River Delta was precipitated by salt-water incursion during an extreme drought in the summer of 2012 and was most severe in areas exposed to greater flooding. Using 16 years of data (2007-2022) from a coastwide network of monitoring stations, we show that the impacts of the dieback lasted five years and …

In an age of species declines, delineating and discovering biodiversity is critical for both taxonomic accuracy and conservation. In recent years, there has been a movement away from using exclusively morphological characters to delineate and describe taxa and an increase in the use of molecular markers to describe diversity or through integrative taxonomy, which employs traditional morphological characters, as well as genetic or other data. Tiger beetles are charismatic, of conservation concern, and much work has been done on the morphological delineation of species and subspecies, but few of these taxa have been tested with genetic analyses. In this study, …

The Taxonomic Report of the International Lepidoptera Survey
This study presents new findings based on a large-scale analysis of butterfly genomic sequences. Focusing on species identification through comparative genomics, we define subspecies as populations differentiated to a lesser extent than distinct species ("species in the making"). Additionally, we propose further adjustments to the current butterfly classification. As a result, 3 subgenera, 12 species, and 4 subspecies are described as new. New subgenera are (type species in parenthesis): Hyalaus Grishin, subgen. n. (Papilio epidaus E. Doubleday, 1846) of Eurytides Hübner, [1821] (Papilionidae Latreille, [1802]) and Astria Grishin, subgen. n. (Lycaena astraea Freyer, 1851) of Glaucopsyche Scudder, 1872 …
Checklist And Key To The Millipede Species Of Georgia, United States, With Notes On Distribution, Lance Andrew, Bruce Snyder
Checklist And Key To The Millipede Species Of Georgia, United States, With Notes On Distribution, Lance Andrew, Bruce Snyder
Graduate Research Showcase
Millipedes are an exceptionally diverse class of animals that have an impact on soil structure and nutrient cycling. Despite their abundance, importance, and wide distribution, they are understudied compared to other animal taxa, and biogeographical information is scant. Georgia, though the largest state by land area east of the Mississippi River, has largely been overlooked by regional millipede checklists. Without baseline species distributions and abundances to inform wildlife management decisions, sufficient measures cannot be taken to preserve millipede biodiversity, especially in light of recent changes in climate and land use. Taxonomic resources for millipede identification in North America are also …

We present the Urban Nature Indexes (UNI), a comprehensive tool that measures urban ecological performance under one standard framework linked to global commitments. The UNI was developed by interdisciplinary experts and evaluated by practitioners from diverse cities to capture each city’s ecological footprint from local to global scale. The UNI comprises six themes (consumption drivers, human pressures, habitat status, species status, nature’s contributions to people, and governance responses) that encompass measurable impacts on climate change, biodiversity loss, ecosystem services, pollution, consumption, water management, and equity within one comprehensive system. Cities then adapt the UNI to their context and capacity by …
Assessing Changing Carbon Pool Dynamics And Species Composition In A Pennsylvania Broadleaf Forest Fragment, Kyleigh Levinsky, Jessica L. Schedlbauer

Temperate broadleaf forests are pivotal to the global carbon cycle, Representing 37% of the global forest carbon pool (Pan et al 2011). • Maintaining compositional diversity in temperate broadleaf forests, such as the Gordon Natural Area (GNA) is critical to maintaining ecosystem services, such as carbon sequestration. • Pressures from native and non-native herbivores threaten the biodiversity of temperate broadleaf forests in the United States (Ghandi et al. 2010). The introduction of non-native insects such as the emerald ash borer (Argrilus planipennis), as well as the overpopulation of white-tailed deer (Odocoileus virginianus) has led to declines in some tree species. …
When John Locke Meets Lao Tzu: The Relationship Between Intellectual Property, Biodiversity And Indigenous Knowledge And The Implications For Food Security, Paolo Davide Farah, Marek Prityi
When John Locke Meets Lao Tzu: The Relationship Between Intellectual Property, Biodiversity And Indigenous Knowledge And The Implications For Food Security, Paolo Davide Farah, Marek Prityi
Articles
This article aims to examine the relationship between the concepts of intellectual property, biodiversity, and indigenous knowledge from the perspective of food security and farmers’ rights. Even though these concepts are interdependent and interrelated, they are in a state of conflict due to their inherently enshrined differences. Intellectual property is based on the need of protecting individual property rights in the context of creations of their minds. On the other hand, the concepts of biodiversity, indigenous knowledge and farmers’ rights accentuate the aspects of equity and community. This article aims to analyse and critically assess the respective legal framework and …
