Premium Membership – All the Fun, Less EffortPremium Membership allows you to spend less time at the computer so that you can spend more time geocaching!Here are four ways that you can save time using Premium Membership features:1. Search for caches in an area using Pocket Queries. You won’t need to sift through search results to find caches that meet your requirements, because this super-advanced search allows you to specify which cache types, cache sizes, difficulty and terrain ratings and attributes (such as “recommended for kids” or “long hike”) are returned in the results.2. Receive up to 1000 geocache listings per Pocket Query. You may think, “I’ll never find that many caches,” but having 1000s of listings ready to go on your GPS gives you the freedom to change your mind about where you are going geocaching at the last second.3. Upload more complete geocache listings to your GPS. In addition to information that Basic Members receive when uploading cache listings, your file includes the cache description, hint and 20 most recent logs. This means you’ll no longer need to print out papers with the cache information!4. Sort by most “favorited” caches. Do you only have time to find a cache or two and want to ensure that you are seeking the best ones in the area? You don’t need to look at the listings page by page… Premium Members can organize search results by how many Favorite Points each cache has received. Caches that receive a high number of Favorite Points are likely to be quality caches that offer an enjoyable adventure.Premium Membership is only $10 for 3 months or $30 for one year.

Experimental study on the effect of diet on fatty acid and stable isotope profiles of the squid Lolliguncula brevis
Fatty acid and stable isotope analyses have previously been used to investigate foraging patterns of fish, birds, marine mammals and most recently cephalopod species. To evaluate the application of these methods for dietary studies in squid, it is important to understand the degree to which fatty acid and stable isotope signatures of prey species are reflected in the squids’ tissue. Four groups of Lolliguncula brevis were fed on prey species with distinctly different fatty acid and stable isotope profiles over 30 consecutive days. One group of squid were fed fish for fifteen days, followed by crustaceans for a further fifteen days. A second and third group were fed exclusively on fish or crustaceans for thirty days. And a fourth group was fed on a mixture of fish and crustaceans for thirty days. Analysis of squid tissue showed that, after 10 days of feeding, fatty acid profiles of squid tended to reflect those of their prey. Squid that fed on a single prey type, i.e. fish or crustacean, showed only minor modifications in fatty acid proportions after the initial change and fatty acid profiles were clearly distinguishable between the two feeding groups. Shifts in fatty acid proportions towards respective prey profiles could clearly be observed in squid the diet of which was swapped after 15 days. Clear differences could also be seen in fatty acid profiles of squid feeding on a mixed diet with trends towards either fish or crustacean fatty acid signatures. Stable isotope signatures of squid tissues clearly distinguished between animals feeding on different diets and supported findings from fatty acid analysis, thus indicating both methods to be viable tools in feeding studies on squid species.
