Abstract:
Less than one percent of marine natural products characterized since 1963 have been obtained from the phylum Bryozoa which, therefore, still represents a huge reservoir for the discovery of bioactive metabolites with its ~6000 described species. The current review is designed to highlight how bryozoans use sophisticated chemical defenses against their numerous predators and competitors, and which can be harbored for medicinal uses. This review collates all currently available chemoecological data about bryozoans and lists potential applications/benefits for human health. The core of the curren

Abstract:
Freshwater Bryozoa is one of the less explored or ignored animal groups from India. Kagzipura Lake, a rainwater fed water body was surveyed for three years to understand the diversity and distribution of bryozoan fauna. The present study depicts four Phylactolaemata bryozoans species as Rumarcanella vorstmani, Plumatella casmiana, Lophopodella carteri and Swarupella divina. The manuscript provides brief descriptions of these species, photomicrographs of statoblasts using scanning electron microscopy and colony characteristics.

AbstractBryozoans (also known as ectoprocts or moss animals) are aquatic, dominantly sessile, filter-feeding lophophorates that construct an organic or calcareous modular colonial (clonal) exoskeleton1–3. The presence of six major orders of bryozoans with advanced polymorphisms in lower Ordovician rocks strongly suggests a Cambrian origin for the largest and most diverse lophophorate phylum2,4–8. However, a lack of convincing bryozoan fossils from the Cambrian period has hampered resolution of the true origins and character assembly of the earliest members of the group.

Abstract:
A preliminary comparative analysis of colony growth and zooid size in the perennial bryozoan Flustra foliacea (Bryozoa: Cheilostomatida) reveals reduced colony growth in the Bay of Fundy relative to growth in the Menai Straits and the Skagerrak, while seasonal fluctuations in zooid size are in synchrony with temperature regimes. Such retrospective morphometric analyses may allow inferences of primary productivity and thermal regimes and provide insights into the life histories of both Recent and fossil bryozoans.

Rapid anthropogenic production of CO2 has driven the carbonate chemistry of the sea, causing lowered pH in surface waters. Increasingly, scientists are called on to study ocean acidification and its effects. The ‘minor’ phylum Bryozoa shows considerable potential in understanding temperate southern hemisphere shelf carbonate dynamics, thus complementing tropical studies based mainly on corals. Lowered pH affects skeletons differently depending on their composition, but skeletons are even more strongly affected by morphology.

Lack of an adequately calibrated Devonian time scale precludes satisfactory comparisons of Recent and Devonian bryozoan diversities. Nevertheless, Devonian bryozoans apparently are 3–100 times less diverse than Recent bryozoans.

Abstract:
Cuyahoga Valley National Park (CUVA) was established as Cuyahoga River National Recreation Area on December 27, 1974, to preserve and protect the Cuyahoga River Valley and its historic, scenic, natural, and recreational values. While not explicitly mentioned in the park?s mission statement, paleontological resources preserved at CUVA are nevertheless of importance, particularly when considering the significant fossil discoveries made elsewhere across northeast Ohio. The upper Paleozoic geologic strata of CUVA encompass sedimentary rocks dating from the Late Devonian to the Early Pennsylvanian,

Abstract:
Effigy Mounds National Monument (EFMO) in northeastern Iowa was proclaimed on October 25, 1949, to protect a significant concentration of Native American burial mounds, many of which were built in the shapes of animals such as bears. Many of these effigy mounds are found atop commanding bluffs flanking the Yellow River at its junction with the Mississippi River. The geology of the monument has not been a central interest in its history, but the rocks contain evidence of millions of years of shallow marine life from the early Paleozoic. Paleozoic fossils were first documented at what is now EFM

Abstract:
Colonial National Historical Park (COLO) in eastern Virginia was established for its historical significance, but significant paleontological resources are also found within its boundaries. The bluffs around Yorktown are composed of sedimentary rocks and deposits of the Yorktown Formation, a marine unit deposited approximately 4.9 to 2.8 million years ago. When the Yorktown Formation was being deposited, the shallow seas were populated by many species of invertebrates, vertebrates, and micro-organisms which have left body fossils and trace fossils behind.

Abstract:
Vicksburg National Military Park (VICK) was established for its historical significance as a one of the principle military sieges resulting in a turning point during the American Civil War. The steep terrain around the city of Vicksburg was integral in the military siege, providing high vantage points and a substrate that was easy to entrench for the armies, but unknown to many is the fossil content, particularly a diversity of fossil mollusks. These fossils at VICK are important paleontological resources which have yet to receive focused attention from park staff, visitors, and researchers. T

Abstract:
Grand Canyon-Parashant National Monument (PARA) in northwestern Arizona has significant paleontological resources, which are recognized in the establishing presidential proclamation. Because of the challenges of working in this remote area, there has been little documentation of these resources over the years. PARA also has an unusual management situation which complicates resource management. The majority of PARA is administered by the Bureau of Land Management (BLM; this land is described here as PARA-BLM), while about 20% of the monument is administered by the National Park Service (NPS; th
