Diatoms of North AmericaConnecting to Foster Understanding and Conservation of Spring Ecosystems
Springs are unique habitats consisting of multiple ecotones connecting
groundwater and surface-water systems, aquatic and terrestrial realms,
and the springhead with a spring-fed stream, pond, or marsh. They are
extremely diverse geologically, chemically, and biologically. They also
vary widely in terms of landscape connectivity, ranging from extremely
isolated desert springs to mesic springs with downstream connections to
extensive stream drainage systems. Connectivity of springs is critical
for their conservation; it affects the genetic differentiation and
endemicity of populations, the welfare of downstream species, and
effects of invasion by non-native species into spring systems.
Freshwater scientists focusing on springs are globally a small (<100)
community and until recently worked largely in isolation. However,
international networks are fostering collaboration, including the
sharing of expertise, data, sites, and research opportunities. This
Special Session focuses on the importance of fostering collaboration
among scientists and other stakeholders in conserving freshwater
springs, which are important economically, culturally, and
scientifically. Topics will include the importance of connectivity among
spring habitats and the people studying them, and the scientific value
of springs as natural laboratories for studying the biological
consequences of environmental change.
