Anggota Famili Poeciliidae merupakan ikan introduksi dengan karakteristik berukuran kecil, live-bearers, dimorfi seksual dari segi ukuran tubuh, pola warna dan struktur gonopodium sebagai ciri diagnostik pada ikan jantan. Ikan ini berperan sebagai pengontrol perkembangan nyamuk malaria dan model pembelajaran biologi. Sejauh ini kajian taksonomi dan penelusuran hubungan kekerabatan didalam famili Poeciliidae belum ada. Tujuan penelitian ini adalah mengidentifikasi jenis, kekerabatan dan pengelompokkan berdasarkan karakter morfologi (morfometrik, meristrik, gonopodium dan ciri diagnostiknya). Jenis penelitian ini adalah deskriptif eksploratif, dengan pendekatan survey. Pada penelitian ini ditemukan tiga spesies ikan Poeciliidae yaitu Xiphoporus helleri, Poecilia mexicana dan Poecilia reticulata. Dendogram hasil analisis morfologi menggunakan metode UPGMA diperoleh dua kelompok percabangan apomorfi yaitu kelompok Genus Xiphoporus dan Genus Poecilia. Sub Clade automorfi antara Xiphoporus helerri A dan B dengan nilai kesamaan 92%. Pengelompokkan ikan Poeciliidae dibedakan berdasarkan lima karakter utama terpilih yaitu: SL (standart length), Hdl (Panjang kepala), Panjang gonopodium, panjang sirip ekor dan PreDL (Panjang sebelum sirip dorsal).Kejelasan identifikasi ikan introduksi khas Telaga Sari menjadi modal utama dalam aquaculture, manajemen, konservasi, biodiversitas dan perkembangan ilmu pengetahuan.

ABSTRACT Poeciliids comprise around 300 species inhabiting the fresh and brackish waters of the Americas and Africa. Poecilia reticulata is native to Northeastern South America and Trinidad and Tobago. In this paper, introduced specimens of P. reticulata collected in the lower Paraguay River in Argentina, were characterized by means of molecular and taxonomic approaches. We further explore, by means of DNA Barcoding, the singularity of the genetic identity of these specimens. Ocurrence of P. reticulata in the lower Paraguay River represents the first record of this species in Argentina. Thirteen individuals of P. reticulata were collected. DNA barcoding showed that all five specimens sampled belong to a single mitochondrial lineage, which was also present in 11 countries from five continents. The distance-based tree clearly grouped separetely four different clusters of P. reticulata when including public data. Genetic distance between the most divergent P. reticulata almost paralleled distance between this species and Poecilia mexicana and P. vivipara. Established populations from Paraguay could be one of the plausible sources for the introduced populations recorded in the lower Paraguay River. The presence of P. reticulata in an open waterway with known drainage to a natural stream is of major concern.

Cooperation among non-kin is well documented in humans and widespread in non-human animals, but explaining the occurrence of cooperation in the absence of inclusive fitness benefits has proven a significant challenge. Current theoretical explanations converge on a single point: cooperators can prevail when they cluster in social space. However, we know very little about the real-world mechanisms that drive such clustering, particularly in systems where cognitive limitations make it unlikely that mechanisms such as score keeping and reputation are at play. Here, we show that Trinidadian guppies ( Poecilia reticulata ) use a ‘walk away’ strategy, a simple social heuristic by which assortment by cooperativeness can come about among mobile agents. Guppies cooperate during predator inspection and we found that when experiencing defection in this context, individuals prefer to move to a new social environment, despite having no prior information about this new social group. Our results provide evidence in non-human animals that individuals use a simple social partner updating strategy in response to defection, supporting theoretical work applying heuristics to understanding the proximate mechanisms underpinning the evolution of cooperation among non-kin.
