    1. Conspicuous colors (e.g., red, yellow, blue) have evolved numerous times across animals. But the function of this coloration can differ radically among species. Many species use this coloration as a sexual signal to conspecifics, whereas others use it as a warning signal to predators. Why do different species evolve conspicuous coloration in association with one function as opposed to the other?

      Los colores llamativos (p. ej., rojo, amarillo, azul) han evolucionado en numerosas ocasiones entre los animales. Pero la función de esta coloración puede diferir radicalmente entre especies. Muchas especies utilizan esta coloración como señal sexual para sus congéneres, mientras que otras la utilizan como señal de advertencia para los depredadores. ¿Por qué diferentes especies desarrollan una coloración llamativa en asociación con una función y no con la otra?

    2. Using phylogenetic logistic regression, we found that conspicuous, sexually dimorphic coloration is significantly associated with diurnal lineages (e.g., many birds and lizards). By contrast, the evolution of warning signals was significantly associated with large-scale clades that were ancestrally nocturnal (e.g., snakes, amphibians), regardless of the current diel activity of species. Overall, we show that the evolution of conspicuous coloration as warning signals or sexual signals is influenced by the ecology of species, both recently and in the ancient past.

      Utilizando regresión logística filogenética, encontramos que la coloración llamativa y sexualmente dimórfica está significativamente asociada con linajes diurnos (por ejemplo, muchas aves y lagartos). Por el contrario, La evolución de las señales de advertencia se asoció significativamente con clados a gran escala que eran ancestralmente nocturnos (p. ej., serpientes, anfibios), independientemente de la actividad diaria actual de las especies. En general, mostramos que la evolución de la coloración llamativa como señales de advertencia o señales sexuales está influenciada por la ecología de las especies, tanto recientemente como en el pasado antiguo.

    1. Heritable (genetic) female-limited colour polymorphisms are also common in Odonata, with one female morph typically exhibiting male-like (androchrome) colouration and one or two morphs exhibiting female-specific colouration (gynochromes).

      Los polimorfismos de color limitados a las hembras heredados (genéticos) también son comunes en Odonata, con un morfo femenino que generalmente exhibe una coloración similar a la masculina (androcromo) y uno o dos morfos que exhiben una coloración específica de la hembra (ginecromos).

    1. How do you refer from and to multiple sources? .t3_15eljnf._2FCtq-QzlfuN-SwVMUZMM3 { --postTitle-VisitedLinkColor: #9b9b9b; --postTitleLink-VisitedLinkColor: #9b9b9b; --postBodyLink-VisitedLinkColor: #989898; }

      Usually if I find a quote somewhere, I'll try to track down the original source, check the context and excerpt it from the original. If it's something mission critical, I might note that it was excerpted and used in other sources and whether it was well excerpted for their case or not. Sometimes, quoting can also help to make a solid case about the influence a work had and notes on that can be a useful thing. If I make multiple notes about the same sort of idea, that's fine, though I typically try to file them all next to each other for easy consultation and comparison, if necessary. As an example, I have quotes from multiple sources about note taking indicating that one should only write on one side of a(n index) card. Some quote earlier sources, some state it without attribution, some say they've learned to do so over time and with experience. Some give reasons why and some don't. The only way to track these practices over time is to note them all together for comparing and contrasting. It wasn't until I'd seen the third mention that I realized the practice was an interesting/important one and worth tracking, so I had to go back and dig up the originals which I had written briefly on their bibliographic cards with page numbers, so it made things easier to create main cards out of them. Because they're all stored together, there's only one index entry for them (for the first one), under "note taking" with the subheading "write only on one side". Alternately I might have made a single note card about the idea of the practice and created a list with pointers of those who used it (or didn't) and links to the sources where I originally found them. Do what makes most sense for you for tracking based on your own situation and needs. You may also find that these things happen frequently when doing literature reviews and things are repeated often within a field. Sometimes it's helpful to figure out who said a thing first and whether or not others are repeating/quoting them or coming to the same conclusion on their own. Is it a solid conclusion? What is the evidence or lack thereof? The only way to know is to start keeping track of these patterns in your reading and notes. Where and how you choose to track it in your zettelkasten is up to you. Sometimes it may be in brief notes with the original source, sometimes in a "hub note", and still others broken out into primary cards collected together.
