From to , Gretsch serial numbers are sequential, but the manner and placement of the serial numbers on the guitars varies quite a bit. Toward the end of , Baldwin took over the Gretsch Company. These serial numbers were also either 5 or 6 digit numbers, depending on the month of production. The numbers were once again located on the back of the headstock and would have been printed in Gold, Black or White depending on the color of the guitar. Obviously, with the change of the decade, there is plenty of room for confusion in interpreting the numbers. The numbers for the months, October 10 , November 11 , and December 12 , can also be interpreted as 10 January , 11 January and 12 January The only way to be clear, is to have an understanding of the feature sets of the instruments from the era. In about , Gretsch began to use another version of the Orange and Grey label on F-Hole instruments. It was used until In , the 2nd iteration of the Baldwin era Gretsch label was introduced.

To know if carbon dating is accurate, we would have to know how much carbon was in the atmosphere in the beginning, and also how long it has been increasing, or decreasing. Since no one was there, no one knows for sure. It’s like trying to figure out how long a candle has been burning, without knowing the rate at which it burns, or its original size. Living penguins have been carbon dated and the results said that they had died 8, years ago! This is just one of many inaccurate dates given by Carbon dating.
The shells of living mollusks have been dated using the carbon 14 method, only to find that the method gave it a date as having been dead for 23, years! Science vol.

Newswise — Climate change is nothing new. For thousands, perhaps millions of years, Antarctica’s massive ice sheet – 5. Yet, until recently, there was no precise way to measure the shifting interface between ice and open water. Emslie has determined a history of penguin colony locations that spans the last 45, years, the longest record now known for any species of penguin. He has charted the ancient penguin colonies’ population shifts with climate change data and sea-ice extent to create a new and reliable method of dating ice movement.
These penguin remains are the focus of two recent articles by Emslie, the second of which appeared as the cover story in the July 10 issue of the Proceedings of the National Academy of Sciences , a leading scientific journal in the U.
If you feel like you’ve been consistently getting the wrong guys, maybe it’s time to change your approach to the dating scene. I know, it may.
A penguin using an artificially-constructed nest in Galapagos. Galapagos penguins are the rarest and most endangered penguin species in the world, and the only penguins found at the equator. Unlike most cold-water penguins, they have several adaptations that allow them to tolerate the warmer climate of Galapagos. When the currents that feed Galapagos are cold and full of sardines and other small fish, the penguins will molt, breed, and feed their nestlings.
They stop breeding and abandon their young. One of the reasons for the endangered status of the penguins is limited nesting options. Many nests small caves or crevices in lava used 40 years ago either no longer exist, are used by marine iguanas, or get periodically flooded. In an attempt to rebuild the penguin population, Dr.
Dee Boersma of the University of Washington and her research team built high-quality, shady nest sites in Boersma counted over penguins, but only one juvenile. The adults were skinny and coated with green algae, indicating that they had been spending lots of time in the water looking for food. Penguins were using both constructed and natural nests.

Jeffrey Wayne White Follow. Foraging ecology in the crested penguins genus: Eudyptes is an active area of research, with new techniques rapidly increasing our understanding of these charismatic species. The most common techniques to assess foraging ecology include stomach content analysis, fecal DNA analysis, stable isotope analysis, tracking, and video loggers.
Here we review dietary research on all 8 taxa within the genus Eudyptes to identify gaps in our current knowledge. However, foraging studies that assess dietary segregation require a method for quickly and accurately sexing penguins in the field. Obvious sexual dimorphism in plumage is largely absent in penguins leaving behavioral cues for sex determination.
We identified morphological characters that could be easily measured in the field to predict sex in the Fiordland penguin tawaki; Eudyptes pachyrhynchus by assessing the correlation between five morphological metrics and individual sex as determined by a PCR-based molecular approach. We found that a combination of foot length and either bill length or bill depth was the most accurate morphological approach to determine individual sex in the field.
Australia has a fossil record of penguins reaching back to the Eocene, yet today is inhabited by just one breeding species, the little penguin Eudyptula minor. The description of recently collected penguin fossils from the re-dated upper Miocene Port Campbell Limestone of Portland Victoria , in addition to reanalysis of previously described material, has allowed the Cenozoic history of penguins in Australia to be placed into a global context for the first time.
Australian pre-Quaternary fossil penguins represent stem taxa phylogenetically disparate from each other and E. Separation of Australia from Antarctica during the Palaeogene, and its subsequent drift north, appears to have been a major event in Australian penguin biogeography. Increasing isolation through the Cenozoic may have limited penguin dispersal to Australia from outside the Australasian region, until intensification of the eastwards-flowing Antarctic Circumpolar Current in the mid-Miocene established a potential new dispersal vector to Australia.

Yellow-eyed penguins YEPs are endemic and endangered and the Otago population is declining with poor breeding seasons and high adult mortality. But YEPs live in the sub-Antarctic too. So how are those penguins doing? So with mainland birds struggling and the last population estimate for the subantarctic dating back to, , it was vital to collect accurate, up-to-date population information. Were the subantarctic populations facing similar struggles to the mainland penguins?
They prefer to nest out of sight of neighbouring birds and nests are an average of metres and up to 78 metres apart. The nests furthest from the sea may be up to 1km inland, making them difficult to find.

Capacity: Maximum 8 participants per tour Remarks: During the penguin breeding season, programme capacity will be adjusted. For the health and safety of all participants, staff and animals, every participant must meet the following criteria in order to participate in the programme. It is highly recommended to make a reservation via internet prior to attending the Park due to the limited capacity. Applications will be considered on a first-come-first-served basis.
Study record managers: refer to the Data Element Definitions if submitting registration or results information. A lower score indicates better function. The participant’s psoriasis disease activity will be assessed by a physician, using a 6-point scale, which ranges from 0 cleared to 5 severe. Investigators assessed each nail abnormality for each of a participant’s nails by grading 3 features or groups of features pitting, onycholysis and oil-drop dyschromia, and crumbling and noting the presence or absence of 4 features leukonychia, splinter hemorrhages, hyperkeratosis, and red spots in the lunula.
The range of possible scores was 0 to , with a score of 0 indicating absence of nail psoriasis and a score of indicating the most severe nail psoriasis. The LEI was developed to assess enthesitis in participants with PsA, and evaluates the presence score of 1 or absence of pain score of 0 by applying local pressure to Lateral elbow epicondyle, left and right, Medial femoral condyle, left and right, and Achilles tendon insertion, left and right.
LEI scores ranging from 0 0 sites with tenderness to 6 worst possible score; 6 sites with tenderness. It is a item questionnaire, where each item will be scored between 0 and All items are prioritized according to importance of the health domain it represents. A higher score on the PsAID indicates more impact of the disease.
