Juvenile loggerhead sea turtle (Caretta caretta) in a plastic pail in South Carolina. Loggerheads are an endangered species, populations of which are declining in part due to human interference with their reproduction cycles. This hatchling was displayed to attendees during an educational event in South Carolina called Keep Light퉌Ís Out for Loggerheads. It was a straggler that was excavated from its nest on the beach. This photo was taken in the wild. Management programs such as this one in SC dig stragglers from the nest four days after the last hatchling track is noted. They collect the hatchlings and then exhume the nest, meaning they collect live hatchlings, count the broken eggshells of ones that already got out and count the dead hatchlings.

Photo of a hatchling loggerhead sea turtle (Caretta caretta) on a beach in South Carolina. Female loggerheads lay their eggs on land and juveniles, such as the one pictured here, migrate from the beach into the ocean. Unlike their adult counterparts that have red shells, juvenile sea turtles have dark-brown shells. This hatchling measured 5 cm (2 inches) long, which is average for the species.

This report defines ecosystem services as a strategy for the conservation of biodiversity. The production of ecosystem goods as it relates to the generation and maintenance of biodiversity is described. Ecosystem services such as flood and drought mitigation, services supplied by soil, pollination, pest control, and seed dispersal are described. Threats to ecosystem services are discussed, as well as their aesthetic, intellectual, and spiritual values. Issues in Ecology is an ongoing series of reports designed to present major ecological issues in an easy-to-read manner. This Issue summarizes the consensus of a panel of scientific experts based on the information that was current and available at the time of its publication in 1997.

This report addresses pollution of aquatic ecosystems that originate from multiple unidentified sources or non point sources. Non point sources of phosphorus and nitrogen are of concern as they cause eutrophication or excessive enrichment of surface waters. Effects and remediation strategies are discussed. Non point sources, such as agricultural, urban and atmospheric ones are discussed. Management techniques to reduce excess nutrient transport across landscapes and into bodies of water are explained. The report discusses the need to establish controversial Thresholds of unacceptable soil contamination. Issues in Ecology is an ongoing series of reports designed to present major ecological issues in an easy-to-read manner. This Issue summarizes the consensus of a panel of scientific experts based on the information that was current and available at the time of its publication in 1998.

Photo of a hatchling loggerhead sea turtle (Caretta caretta) entering the surf on a beach in South Carolina. After hatching, juvenile sea turtles are guided to the ocean by celestial light reflecting off the ocean. Artificial light disrupts this process and serves to reduce reproductive success in loggerheads.

In this report, biodiversity and its relevance to the ecosystems that support humanity is discussed. Ecosystem functioning is defined as the collective activities of all biota within an ecosystem and how they affect its chemical and physical factors; therefore, it can be negatively impacted by decreases in biodiversity-the wide variety of life forms inhabiting the planet. The ecological and economic consequences of losses in biodiversity are explained. Additionally, case studies of scientific efforts to understand ecosystem functioning and to assess biodiversity are presented. Issues in Ecology is an ongoing series of reports designed to present major ecological issues in an easy-to-read manner. This Issue summarizes the consensus of a panel of scientific experts based on the information that was current and available at the time of its publication in 1999.

Example of artificial lighting along a beach. Artificial lights inhibit the reproduction of loggerhead sea turtles (Caretta caretta) in two ways. First, adult females tend to avoid laying their eggs on beaches with artificial light. Second, hatchlings become disoriented and fail to migrate toward the ocean and instead wander along the beach and even further inlands. While wandering, disoriented hatchlings are more susceptible to nocturnal predators and become exhausted. Sources of artificial light include streetlights, sky glow, exterior lights on commercial establishments, beachfront homes, and even people near the beach carrying flashlights and setting bonfires.

This Hubble Space Telescope image shows what appears to be a delicate bubble of gas floating in space. In actuality, the bubble is the visible remnant of a powerful supernova explosion called SNR 0509. The bubble was formed from gas being swept up by the expanding shock wave. The accompanying activity is a curriculum support tool designed for use as an introductory inquiry activity. In the activity, students use the images and text on this lithograph to generate questions about supernova explosions and remnants. They will conduct research to answer their questions, and create a presentation to demonstrate their understanding of the material, providing supporting evidence from their research.

In this report forests are presented as very dynamic ecosystems, and processes such as nutrient cycling, nitrogen saturation, sedimentation, erosion, and forest fragmentation are described. Ecological processes, such as disturbance and succession, are described in relation to forest management. Ecological and economic values and their societal implications are compared. Alternatives to conventional timber harvesting, in efforts to conserve biodiversity, as well as landscape and structure complexity are discussed. The report also discusses deforestation as a contributor to global warming, and allowing naturally occurring ecological disturbances in sustainable timber harvesting practices. Issues in Ecology is an ongoing series of reports designed to present major ecological issues in an easy-to-read manner. This Issue summarizes the consensus of a panel of scientific experts based on the information that was current and available at the time of its publication in 2000.

Image of a loggerhead sea turtle (Caretta caretta) hatchery in South Carolina. Nests are placed in an area where they are protected in varying degrees from natural or anthropogenic hazards. Efforts such as these are intended to increase the success rate of loggerhead reproduction and reverse population declines caused by human activities.

This report illustrates the disruption of the global water cycle as a result of human activities. The global hydrological cycle퉌Ís surface and ground water processes are detailed. The global distribution of freshwater resources and its accessibility to human populations is discussed. The increasing human demand for fresh water sources is addressed, while explaining the differences between renewable and non renewable sources. The report also discusses global warming effects as they relate to the hydrological cycle. Research and management implications to mitigate current and future freshwater supply are mentioned. Issues in Ecology is an ongoing series of reports designed to present major ecological issues in an easy-to-read manner. This Issue summarizes the consensus of a panel of scientific experts based on the information that was current and available at the time of its publication in 2001.
