(parallely the official FACEBOOK page is still climbing with 1046 likes after having crushed the target of 1000 likes early this month, with the full text of this alert and… many statistical numbers where Wilson Costa is by far on the lead while the total number of taxa, including generic names and synonyms, reaches 1500).

  • On July 1. 2015, Dr Huber and K-D-I strongly support a Mexican conservation initiative for Profundulus oaxacae, only known today by 3 small remnant populations (systematically valid based on molecular data, a rediagnosis for scientific recognition is under-way), by a team led by Víctor Ortiz in valley of Etla, Oaxaca state (all details at ENGLISH and at SPANISH)… please consider to support the project either with words or materially, if you have outdoor ponds and rather subtropical climate (click on CONTACT) and with money (click on DONATE) in the above web sites [besides there is possibly a new species], or in addition, with LIKES.

  • On January 13. 2015, the K-D-I board proposes to offer a new grant of 250 € (about 300 US$) for one of the next 3 options (first come, first served) in order to pay for car petrol for a short trip in a safe neotropical country given to a senior aquarist collector at least accompanied by a young aquarist for his first trip.
    1- Brasil, collect at the type locality of Rivulus ornatus [lago Saraca at Silves, Amazonas state, 2.880 S, 58.350 W] and disclose the live colors of the fish in order to uphold an old confusion arisen from 2 independent publications by Costa and Huber on ornatus/obscurus (who is right is totally unknown)
    2- Paraguay, collect at the 2 type localities (distant by a few dozen km) of Neofundulus ornatipinnis [Makthlawaiya, Chaco, 23.420 S, 58.320 W] and paraguayensis [near Arroyo Trementina, 24.830 S, 57.060 W] and disclose for the first time their live colors and if they are either distinct species or the 2 sexes of the same species
    3- Uruguay, collect in northeastern region, not far from the border with Brasil where Cynopoecilus melanotaenia has been found (the identification of the Uruguayan populations is unknown : it may be cryptic new species like fulgens, intimus, multipapillatus, nigrovittatus, or, bingo!, it may be a new morphospecies like notabilis, described a few weeks ago).
    a- to be economic the senior collector should be from Brasil (project 1 or 3), or from Uruguay or Argentina (project 2 or 3)
    b- the accompanying aquarist for his first collecting trip may be a local, too, or from abroad (but his or her expenses will not be covered)
    c- specimens must be preserved (at least 70% ethyl alcohol) to be donated to local researchers from Brasil/Uruguay/Argentina/Paraguay (depending on selected project)
    d- beware that involved localities bear seasonal constraints, in Brasil it is a flooded area and in Paraguay and Uruguay they are annual biotopes
    e- a scientific or aquaristic-serious publication must be derived from the trip (successful or not), mentioning the grant by Killi-Data
    f- K-D-I members may donate additional funds to collectors in order, if successful, to have priority on eggs of collected fish.
  • On November 30. 2014, a new INFOWEB17 is written by Jean H. Huber and published online after an exclusivity period to members (on the first complete molecular analysis of Nothobranchius that reshuffles its phylogeny).
  • On November 19. 2014, a new electronic book in high resolution format is announced by the US researcher and conservationist, Evan Carson, in collaboration with Mexican researchers Mauricio De la Maza and Ma Lozano (the low resolution is freely downloadable at LowRes while the high resolution is available [update of January 13. 2015] at HiRes) ; it studies the conservation status of the microendemic pupfish Cyprinodon julimes and exemplifies the importance of collaborative approaches to biodiversity conservation (by creating bi-national and cross-disciplinary partnership of researchers with engagement with a local community of farmers to create a model of biodiversity conservation through sustainable development of water resources) and it is a must reading ; let us save this unique pupfish by supporting their action !

  • The "guest" section is fully open and anonymous (no e-mail needed to enter) and it is fully updated with automatic programmes and a free RSS feed (easy and free to subscribe to get immediately any alert from Killi-Data)
  • The "members" section is strictly payable after REGISTRATION (no more free granting for any person, contributor or not) : it remains easily affordable (6 Euro, i.e. about 7 US$, for a full year after permanent membership) and it is considerably enriched with new pages and with an automated updating process.
  • The "members" section mainly contains the database and all killiflash since 1978 (all major publications on killifish with reference, abstract and short analysis for each) : to freely check the contents of the database, please read the SAMPLE page, or if you intend to write an article, ask for a GRATUITY page of a given name of killifish.
  • The "guest" section holds a lot of advertising (please readily click on links if interested) : this is aimed to cover the costs of IT development programmes each year so that all fees from "members" are redistributed to young researchers and to aquarists-collectors for their first trip.
  • This is not any more, at the generic level, a mirror of current research (it became too unstable since 2009) but an objective analysis of current knowledge, in order to avoid too numerous name changes without added value and without stability sake ; but this only concerns the generic level, while the species level is, as usual, automatically derived from latest published evidence (beware, that strategy is different from listing various published results and/or published opinions to compare them without deciding).
  • In total, the principles of the project are maintained -data quality and financial redistribution- even if, because the project is not a single person project any more, it may only be long-term living by data contributions from all members.




Communication and cooperation free services:

A new version of the website has been made available early 2012, and for the guest section, browsing is slightly different from the previous version (started in 2001) :

Mission statement

legend  Killi-Data aims to present all available information on Killies or oviparous Cyprinodontiformes fishes.
Killi-Data compiles state of the art knowledge, wherever it sources from, scientist or aquarist.
Killi-Data is evidence based, not opinion based. If conflicting results arise from distinct phylogenetic methods, then a compromise is selected that purports the maximum of results, ending up in a splitting way if stability is not treatened.
Killi-Data is a non-profit venture that redistributes all financial benefits, the major part being attributed to young scientists or collectors to support research on oviparous Cyprinodontiformes fishes or Killies.
Killi-Data strongly encourages cooperation between ichthyologists, either professional or amateur, and aquarists to build a cooperative community of interest and knowledge.
