Does Submerged Aquatic Vegetation Shape Zooplankton Community Structure And Functional Diversity? A Test With A Shallow Fluvial Lake System

Submerged aquatic vegetation (SAV) plays important roles in shallow lakes. In addition to its refuge effect for zooplankton, one key role of SAV is to provide diverse ecological niches to these organisms. The reduction of habitat complexity due to loss of SAV might thus have huge effects on zooplankton communities. The objective of this study was to investigate the relationship between SAV abundance and composition and zooplankton functional diversity and community structure.

Climate Literacy: The Essential Principles Of Climate Science

Climate Literacy: The Essential Principles of Climate Science presents information that is deemed important for individuals and communities to know and understand about Earth's climate, impacts of climate change, and approaches to adaptation or mitigation. Principles in the guide can serve as discussion starters or launching points for scientific inquiry. The guide aims to promote greater climate science literacy by providing this educational framework of principles and concepts.

Climate Change: Global Sea Level

Global mean sea level has risen about 8-9 inches (21-24 centimeters) since 1880, with about a third of that coming in just the last two and a half decades. The rising water level is mostly due to a combination of meltwater from glaciers and ice sheets and thermal expansion of seawater as it warms. In 2018, global mean sea level was 3.2 inches (8.1 centimeters) above the 1993 average - the highest annual average in the satellite record (1993-present)

Climate Change And Social Inequality

This paper offers a unifying conceptual framework for understanding the relationship between climate change and "within-country inequalities," referred here collectively as "social inequality." Available evidence indicates that this relationship is characterized by a vicious cycle, whereby initial inequality causes the disadvantaged groups to suffer disproportionately from the adverse effects of climate change, resulting in greater subsequent inequality

Ask A Scientist: How Do You Know That A Wetland Restoration Is Successful?

Although there is no one "silver bullet" method, much can be done to see if a restoration is on track. Following the restoration plan and keeping track of the inputs (quantity of seed planted, number of species planted as plugs) is one way to make sure that restoration targets are met. However, strictly following these steps does not guarantee success, as many unexpected obstacles might occur (a dry or a wet year, a new invasive species, inability to conduct a burn). That is why most restoration and conservation managers, including TWI ecologists, follow a strategy called adaptive management.

A Lesson Learned For Community Resettlement: Isle De Jean Charles Band Of Biloxi-Chitimacha- Choctow Tribe

The resettlement plan is expected to be implemented by 2022 with the inclusion of many facilities in the new location to revitalize the tribal community, including a tribal center and a healthcare facility. The Tribe's experience highlights how success can be achieved when at-risk communities are engaged in the resettlement planning process from the beginning to ensure long-term successful relocation and maintain community integrity. It also highlights an opportunity for institutions to evolve in more flexible ways to accommodate the growing number of communities that may need to relocate.

A Global Crisis For Seagrass Ecosystems

Seagrasses, marine flowering plants, have a long evolutionary history but are now challenged with rapid environmental changes as a result of coastal human population pressures. Seagrasses provide key ecological services, including organic carbon production and export, nutrient cycling, sediment stabilization, enhanced biodiversity, and trophic transfers to adjacent habitats in tropical and temperate regions.

Biogeography Of Submerged Aquatic Vegetation (Sav) In The Pontchartrain Basin

A biogeographic study of submerged aquatic vegetation (SAV) in the Pontchartrain Basin of southeastern Louisiana was conducted. These plants provide numerous essential ecosystem services. Eighteen species occurred in different salinity zones ranging from freshwater to the saline waters of the Gulf of Mexico. Lake Pontchartrain SAV coverage was reduced by 70 percent from 1953 to 1990 due to increased turbidity from urbanization and shell dredging.

Welcome To The Age Of Climate Migration (Explicit Language)

Politicians inevitably vow to rebuild, to make their city stronger than before. But in the coming years, as the climate gets hotter, the seas keep rising and storms grow more intense, those vows will become less and less credible. Climate change is going to remap our world, changing not just how we live but where we live. As scientist Peter Gleick, co-founder of the Pacific Institute, puts it, "There is a shocking, unreported, fundamental change coming to the habitability of many parts of the planet, including the U.S.A.
