Analytical methods of assessing the response of groundwater levels to a range of factors, including elastic (barometric and tidal) influences in confined aquifers and recharge to unconfined aquifers due to infiltration of rain and other surface water, are presented. Responses in a confined aquifer to distant recharge events and the associated time lag is discussed. Also covered are responses to changes in storage volume resulting from direct recharge at the outcrop of an unconfined aquifer sy...

An accessible, authoritative look at seahorses, their evolution, biology, habitat, and behavior.Absolutely captivating creatures, seahorses seem like a product of myth and imagination rather than of nature. They are small, elusive, and are named for their heads, which are shaped like miniature ponies with tiny snouts. They swim slowly upright by rapidly fanning their delicate dorsal fin, coil their tails to anchor themselves in a drift, and spend days in a dancing c...

Throughout history, the influence of the full Moon on humans and animals has featured in folklore and myths. Yet it has become increasingly apparent that many organisms really are influenced indirectly, and in some cases directly, by the lunar cycle. Breeding behaviour among some marine animals has been demonstrated to be controlled by internal circalunar biological clocks, to the point where lunar-daily and lunar-monthly patterns of Moon-generated tides are embedded in their genes. Yet, i...
