As explorers and scientists have identified for many years, the Neotropics harbor a phenomenal array of our planet’s mammalian variety, from capybaras and capuchins to maned wolves and mouse opossums to sloths and sakis. This organic bounty should be attributed in part to the amazing variety of Neotropical landscapes and climates and partially to a sequence of continental connections that accredited intermittent faunal exchanges with Africa, Antarctica, Australia, and North the USA.

Example text

This piston design has the added advantage of being able to lock into the sample holder at the end of a drive. At the end of a drive the tube is filled with sediment and the piston is at the top of the sample tube, pressed against the tube holder. But now one must pull the tube out, creating a powerful suction that will tend to pull both piston and sediment out of the tube again. To prevent this, the piston must be pulled up at the same rate as the sample tube. We can do this by pulling on the piston cable—one person pulling up rods A guide to piston coring of lake sediments 35 while a second pulls up the cable at the same rate.

At sampling depth this ‘sliding rod’ is withdrawn and its end locked in place as the bottom of the drill string. The alternative is to design a piston that locks inside the mouth of the sample tube until released by tension on the piston cable. The widely used ‘square rod’ sampler is of the first or ‘sliding rod’ type. The push rods of the drill string are connected to the sampler by a special last rod that is square in cross section. The square rod slides through a square aperture in the sample tube holder until its bottom rests against the piston.

Forest birds and butterflies of some genera exist as distinct species in different parts of the Amazon basin such that their mapped distributions look like separate islands in a sea of green forest. Moreover some of the butterfly and bird isolates have roughly Amazon Pollen manual and atlas 28 concentric distributions, occupying as it were the same ‘isolate’ in the unbroken sea of forest. 2). The birds and butterflies of these isolates are close relatives and are thus species that have certainly evolved from common ancestors within the forest.
