Despite their prominence in many coastal habitats, New Zealand seaweeds have until now lacked a photographic handbook of the type available for our marine invertebrates, fishes and birds. This gap has now been filled with an excellent book by New Zealand’s resident seaweed authority, Prof. Wendy Nelson of the National Institute of Water and Atmospheric Research and the University of Auckland.
The temperate coastal waters of New Zealand are home to a seaweed flora that is every bit as interesting as our better-known terrestrial flora. Like land plants, seaweeds generate oxygen through photosynthesis and are important food and habitat for a variety of animals. However, living in the ocean imposes unique challenges on seaweeds.
Light is absorbed very rapidly underwater, so seaweeds are restricted to the shallows where water motion is often strong. Moderate water movement enables rapid growth by replenishing nutrients, but violent wave action abrades seaweeds against rocks and sometimes rips whole individuals loose. To resist these forces, seaweeds need to be streamlined, flexible, tough, and well attached to a firm substrate, while still presenting plenty of surface area for absorbing light and nutrients. Within these constraints a great variety of morphologies are possible, and seaweeds with the right formula for a particular location can be very abundant and productive.
This is the first substantial guide to our seaweeds since the similarly-titled Seaweeds of New Zealand: An Illustrated Guide (Canterbury University Press) by the late Nancy Adams came out in 1994. Prof. Nelson covers the most common third of our 787 known seaweed species, in a reasonably-sized and priced paperback format. Adams’ award-winning book covered the entire flora (over 600 species at the time), which required 360 pages in hardcover A4 format. It was illustrated with watercolour paintings and pencil drawings. While these are useful for highlighting taxonomically important characteristics, a good photograph can better represent the organism as it is likely to be encountered in the field.
Subtidal seaweeds, in particular, often look very different underwater when upright and expansive than they do as the dry pressed specimens that presumably were the basis for many of Adams’ illustrations. Prof. Nelson has obtained fine in situ images from a number of photographers throughout the country, and has supplemented these with watercolour paintings from Adams’ book and/or photomicrographs. Together they showcase the full range of seaweed diversity found on our shores.
Cats threaten endangered species.2008-06-13 10:33:07 by SciLite
GAINESVILLE, Fla. - With 4 million to 6 million unwanted animals - mostly cats - put to sleep each year in the United States, some people might consider it more humane to free the felines into the wild.
But as these cats forage for food and establish their territories, they kill more than a billion small mammals and birds each year, many of which are threatened or endangered, a University of Florida study shows.
Feral, or free-roaming, untamed cats pose a serious threat to endangered species nationwide as colonies of the wild cats have grown, largely because local groups provide funding and resources to sustain them, according to the UF study commissioned by the U

“This allows the predator fish to feed heavily on the forage fish species. Consequently, the predator fish species are fatter and healthier during the next years spawning season,” she explained.
