How To Rid Of Broken Blood Vessels Naturally
Tweet
In some previous entries in this blog ( 1 , 2) as well as in a publication , we commented on the importance the distinction between the conservation of wildlife populations and respect the rights of individual animals. I just read an article that illustrates very well the conservation of populations and respect for animal rights are two different things, sometimes they can go in the opposite.
Atlapetes pallidiceps is one of the most endangered birds of South America, who even was thought extinct until recently. In a recent study, Niels Krabbe and colleagues documented an encouraging increase in the population of these birds for over 10 years Yunguilla reserve, Ecuador.
The recovery of the population seems to be due to a conservation action undertaken in the study area, consisting of controlling populations of Chamon Molotrhus bonariensis, a bird brood parasitism (laying eggs in the nests of other birds, reducing the reproductive success of hosts). What is meant by control? Basically, kill "Cowbird control Undertaken by WAS AS, Who Spent The Entire breeding season Every year from 2003 onwards (late February to early May) shooting cowbirds (Molothrus bonariensis ) Females preferentially, as soon as These Approaches: a or Enter the book. " .
In total, killed (shot) 239 Chamone (mainly Chamona) in six years and this has apparently resulted in a reduction in the rate of parasitism of nests A. pallidiceps , which decreased from 61% to almost 0%. In parallel with the control Chamon, the population of the endangered species grew, as The following figure shows.
Is it more important to keep the population of an endangered species or the lives of dozens of individuals of other species? For conservationists the answer seems clear. For animals not so obvious.

Science magazine published this week news story in connection with the scandal over the new kind of Grallaria discovered by Diego Caranton and first described by Proaves Foundation in an article in which Diego did not appear as a contributor. The note of Science is quite brief, more a news article that opinion, but has a very revealing statement of the outgoing executive director Proaves, who said they needed to name the species for money ...
Today I learned that Proaves just published an editorial in his magazine in which he defends his actions in history. In addition, they respond to several points that Gary Stiles and I boarded our editorial in Colombian Ornithology, and make several additional charges against me.
wear I think I've had enough and it's time to turn the page with all this, so I will not respond specifically to sections in which Proaves question my professionalism and my honor. Therefore, I will not answer the letter insulting George Fenwick (President of American Bird Conservancy, ABC, and honored with the name of Grallaria fenwickorum ) sent to the editor of Birding Magazine in response to a letter I had sent earlier in clamoring for a public clarification from Proaves and their supporters, including ABC. We have the answers and let the people decide what position to take.
One detail that I do want to clarify, which appears in the letter from Fenwick of Birding as in the latest editorial Proaves has to do with the relationship that existed between the breakdown of negotiations for the publication of the new species and the name that is baptized. The reason why I just went out of the process, as I explained in an editorial last year, was that I learned that people Proaves was distorting my participation in the discussion with at least one international council member. I did not want to appropriate any discovery, or ignore the work of Proaves; wanted those who deserved credit and who received what they deserved authorship could participate in everything that involves writing and publishing a scientific article. But with the dishonesty that prevails in the discussion, I turned away and I figured that would leave the way clear to enter and Diego Caranton Proaves reach an agreement. Only after refusing to participate was that I told Diego that, in the end, I did not want to participate in a tribute to Fenwick, for reasons already explained. With all this, what I am is the breaking of my participation in the process was not by name, as has been alleged. And Diego's much less. Mine was because I got tired of dealing with deaf and dishonesty. Diego's, as also explained, was because Proaves made him an unacceptable proposal, which implied that he would have no control over the manuscript produced based on his discovery. I thought if I should start to release the emails I exchanged with Proaves in all that time, start a sort of Wikileaks to let people know best the chronological order, the tone and direction of all discussions in which I participated. That would clarify many of the things that seem confusing from the outside, but it would add fuel to the fire and today I think it is better to turn the page.
however, commented on another topic: I have not Proaves accused of doing things without proper permits. Rhetorically asked whether they would permit, but did not claim anything. And now wonder where is the specimen of the new species of owl that they collected? Part of the process responsible for scientific collection includes depositing the specimens in a natural history museum where they can be cared for properly so that they can be studied over the years. Not for me to demand answers, so just throw the question into the air. And I do because I think very curious how Proaves along the process seems to change positions on key issues, policy regarding the collection of specimens. At one point, they had no problem with posting the description with Diego as a contributor. That meant that the collection of specimens would have happened (ie collecting vs. Do not collect) and was not sheltered by a permit (ie vs collect with permission. Collecting without a permit) were not substantive problems that prevented agreement, but later the public against Diego undertaken with strong accusations based on those two issues. Proaves now says in his new editorial that opposes the scientific library and the library owl in question was made legally, fantastic, but to complete the process of collecting specimens is legally required to deliver properly preserved a scientific collection registered with the environmental authorities. I am not implying that they have done, hopefully yes. I am implying that if one is to wield an anti-or pro-gathering, either for ethical reasons, conservation or law, must be consistent with that position.
Finally, I want to comment on why I have been an "activist" in this soap opera in which I now tildan even instigated a boycott ... Frankly, I did not need intefere as Proaves describes it, by any personal interest, but simply reflected my performance that I think young biologists excluded from the publication of the new species (for whatever reason, has violated his contract Diego law or otherwise) made them great harm and this injustice was not necessary. People inside and outside the country knew the other side of the story was important, especially for the way Proaves Diego presented the history of its original publisher Colombian Conservation. That was my interest.
Contrary to what you say out there, I do not I'm lobbying for the name Grallaria urraoensis established. Well, Diego and has lectured Certuche Katherine (one of which I was co-author) in which, naturally, the way the story unfolded, they used the name that they put the new species and not of those who were left forward with the publication. To compensate the damage done to Diego and Katherine, to me I'd be urraoensis be imposed on fenwickorum (one thing is the code naming, other ethical and scientific rigor of the descriptions). But if you are premium priority and these rules dictate that the name of Proaves will either be accepted over time (eg, the SACC spent months waiting for someone to present a proposal to consider recognition of the new species and no one has done, contrary to what has been said).

the owl died.
And the discussion in the media, the indignation of the people are the same as when they killed Pepe, the hippopotamus. Again, people confuse respect for the rights of animals to the conservation of biodiversity, which are different things. (This latter one seem more trills telegraphic entries - maybe it's a good time to start tweeting @ cdanielcadena)

Can You Treat Kyphosis
In our field work, biologists routinely use geo-positioning systems (GPS) to locate. Furthermore, to understand the distribution of species, a central point of our work, we need to know some elementary notions of geography, as knowing place latitude-longitude coordinates on a map. I thought having some of those little things clear but recent events in Colombia, I have suggested that maybe not ...

In this sector of the Chilean economy, construction is experiencing significant changes, with regard to the new regulatory requirements and the general trend improve quality and efficiency in resolving of important issues, including need to reduce energy consumption and increasing environmental comfort in buildings.
is why I wanted them to know the TECHNICAL REGISTRATION MATERIALS of Chile. It is a large and growing list of building materials, with useful technical information on acoustic performance, thermal, fire protection etc.
Well you are an architect and you are designing or own a construction project in mind, this catalog will facilitate decision making.
The presentation is the site is very complete, so simply copy it happened. I hope you find it helpful!.
"CDT is a service of the Technology Development Corporation (CDT) of the Chilean Chamber of Construction, with the support of the Office of Architects Association (AOA), which has the best and most complete knowledge base of materials construction, allowing professionals access to classified information, standardized and verified.
RegistroCDT is an important source of support for the specification of materials, working with architects and construction professionals, through Specifier Guide and Chips with Seal reliable specification.
RegistroCDT supports students, teachers and users in general, by providing the Technical Document Library and Technical Reference sheets, which provide the greatest source of knowledge on construction materials. "

This week I got my hands (thanks to Loreta Rosselli) an article describing a new species of parrot of Colombia. 20 years ago, one of the authors spoke to a poultry dealer Melgar (Tolima), who mentioned the existence of a yellow-necked parakeet. In January 2010, doing fieldwork on the Internet, the authors found a photo which apparently confirmed that indeed there was a sort of yellow-necked parakeet, which had gone unnoticed by scientists.
Based solely on this picture of animals captivity, which appeared on the website of a center of attention and appreciation of wildlife in Ibague, the authors ventured to name a new species: Forpus flavicollis. Because the photo is the only source of information to support this apparent discovery, the authors suggested that the birds probably came from an inaccessible location, not yet visited by ornithologists. In addition, they dared to speculate that as the photo was taken in Ibague, it is reasonable to assume that birds came from Quindío. Maybe nobody told them that is in Ibague Tolima and Quindio not (which probably would have allowed them connecting the discovery of this picture with what the dealer told melgareño), but, of course, this geographical error is not the only problem with the article.
The first error is so serious, is that the article did not designate a type specimen as required by International Code of Zoological Nomenclature , so technically the description of F. flavicollis is invalid. The second error is the background: these birds do not represent a new species! They are simply Cascabelito ( Forpus conspicillatus) to which I have painted or faded plumage to make them look like something different, a common practice among wildlife traffickers. The Cascabelito is one of the most common species of parrots in Colombia, is abundant in the region from which the photo and also, even as the authors acknowledge, in the photo is clear that besides the individual is the yellow-necked but one which undoubtedly is a Cascabelito that has not been adulterated plumage.
ever heard the story that the great Mono Hernández on one occasion did the same, that she thought she found a new species of parrot plumage typical Colombian. However, if I remember correctly, the monkey was careful enough to wait until the birds molt and regain their normal plumage, so the supposed new species was never described (if anyone knows the story well, any comments are welcome) . What I know is that the book parrot of Colombia, and José Vicente Rodríguez Mono, they mention that alter the plumage of parrots is a widespread activity among the dealers of these animals. Perhaps the authors of the description of " flavicollis F. " did not have access to this book ...
So no, we have a new species of parrot in Colombia but simply an example of bad science in relation to the taxonomy of Colombian birds (see also the discussion on another alleged new species). The article is short so out of curiosity is worth reading, but for those interested in learning about a story about the discovery of a new Psittacidae well supported, I recommend more description Nanopsittaca dachillae , masterfully told Don Stap in A Parrot Without a Name.

Yesterday thought revive the blog, which still takes so long, writing something about the course on comparative genomics'm taking in the Czech Republic.
But the horrible news yesterday has left me paralyzed ... Not to abandon the idea that the blog you wake up, and although something would not necessarily appear on a page like this, for now here are a couple of pictures to remember good times with Margarita (in the Sierra Nevada de Santa Marta in 2008) and Matthew (most recently in Tatamá National Park last October.) Please click to enlarge.
not say nothing. How sad and, though sometimes we forget, what country most difficult in which we live ...
