Review of Analysis of Fish Remains at Chumash Sites
A Review of the Analysis of Fish Remains in Chumash Sites Noel Van Slyke Abstract The paper begins with a review of techniques that can be used to analyze fish remains in archaeological sites. The remains can be used to identify the fish species and to estimate such details as fish size and weight, minimum number of individuals represented, and season of capture, and to make judgments about fishing techniques and subsistence patterns. The review of analysis techniques is followed by a discussion of the analysis that has been reported for fish remains from Chumash sites. The paper concludes with comments on the analysis of fish remains from Chumash sites. The inspiration of this paper came from a Christmas present. The present was the book Early Hunter-Gatherers of the California Coast, by Jon M. Erlandson (1994). I was impressed by the level of analysis of fish remains and faunal remains in general. I had previously read earlier reports where the level of analysis was more basic. The topic for this paper then evolved as an attempt to review the change in analysis of fish remains over the years and to look at where further analysis of earlier data might be promising. The Analysis of Fish Remains The basis of all analysis of fish remains is species identification. Once the species have been identified other areas of analysis such as quantification, estimates of size, seasonality consid- erations, exploitation, and subsistence evaluation can be investigated. Identification Identification is the primary step in fish remains analysis. Identification of the species allows other analyses to proceed such as quantification, size estimation, seasonality, and exploitation. -

Fish larvae and particularly eggs are 30 difficult to identify morphologically, therefore the DNA barcoding method was employed to 31 identify 4,388 specimens, resulting in 157 Operational Taxonomic Units (OTUs) corresponding 32 to species. Scarus sp., Halichoeres dispilus, Xyrichtys mundiceps, Euthynnus lineatus, 33 Ammodytoides gilli, Synodus lacertinus, Etrumeus acuminatus, Chanos chanos, Haemulon 34 flaviguttatum, and Vinciguerria lucetia were the most abundant and frequent species recorded. -

A system of specific 16 primers and a Minor Groove Binding (MGB) TaqMan probe based on 17 sequences of the mitochondrial cytochrome b region was designed. The 18 method was successfully tested in 81 specimens of Scomber scombrus and 19 related species and validated in 26 different commercial samples. An average 20 Threshold cycle (Ct) value of 15.3 was obtained with Scomber scombrus DNA. 21 With the other species tested fluorescence signal was not detected or Ct was 22 significantly higher (P<0.001). The efficiency of the assay was estimated to be 23 92.41%, with 100% specificity, and no cross reactivity was detected with any 24 other species. These results reveal that the developed method is a rapid and 25 efficient tool to unequivocally identify S. -

(Platyhelminthes) Parasitic in Mexican Aquatic Vertebrates

(México) [email protected] [email protected] (*corresponding author) [email protected] Published on 29 December 2017 urn:lsid:zoobank.org:pub:34C1547A-9A79-489B-9F12-446B604AA57F Mendoza-Garfias B., García-Prieto L. & Pérez-Ponce De León G. 2017. — Checklist of the Monogenea (Platyhel- minthes) parasitic in Mexican aquatic vertebrates. Zoosystema 39 (4): 501-598. https://doi.org/10.5252/z2017n4a5 ABSTRACT 313 nominal species of monogenean parasites of aquatic vertebrates occurring in Mexico are included in this checklist; in addition, records of 54 undetermined taxa are also listed. All the monogeneans registered are associated with 363 vertebrate host taxa, and distributed in 498 localities pertaining to 29 of the 32 states of the Mexican Republic. The checklist contains updated information on their hosts, habitat, and distributional records. We revise the species list according to current schemes of KEY WORDS classification for the group. The checklist also included the published records in the last 11 years, Platyhelminthes, Mexico, since the latest list was made in 2006. We also included taxon mentioned in thesis and informal distribution, literature. As a result of our review, numerous records presented in the list published in 2006 were Actinopterygii, modified since inaccuracies and incomplete data were identified. Even though the inventory of the Elasmobranchii, Anura, monogenean fauna occurring in Mexican vertebrates is far from complete, the data contained in our Testudines. -
Floating Nurseries? Scyphozoan Jellyfish, Their Food and Their Rich Symbiotic Fauna in a Tropical Estuary
Floating nurseries? Scyphozoan jellyfish, their food and their rich symbiotic fauna in a tropical estuary José M. Riascos1, Willington Aguirre2, Charlotte Hopfe3, Diego Morales1, Ángela Navarrete1 and José Tavera1 1 Instituto de Ciencias del Mar y Limnología, Universidad del Valle, Cali, Colombia 2 Bahía Málaga, Consejo Comunitario Comunidad Negra de La Plata Bahía Málaga, Buenaventura, Colombia 3 Department of Biomaterials, Universität Bayreuth, Bayreuth, Germany ABSTRACT Background. The anthropogenic modification of trophic pathways is seemingly prompting the increase of jellyfish populations at the expense of planktivorous fishes. However, gross generalizations are often made because the most basic aspects of trophic ecology and the diverse interactions of jellyfish with fishes remain poorly described. Here we inquire on the dynamics of food consumption of the medusoid stage of the scyphozoan jellyfish Stomolophus meleagris and characterize the traits and diversity of its symbiotic community. Methods. S. meleagris and their associated fauna were sampled in surface waters between November 2015 and April 2017 in Málaga Bay, an estuarine system at the Colombian Pacific. Stomach contents of medusae were examined and changes in prey composition and abundance over time analysed using a multivariate approach. The associated fauna was identified and the relationship between the size of medusae and the size those organisms tested using least-square fitting procedures. Results. The presence of S. meleagris medusa in surface waters was seasonal. The gut contents analysis revealed that algae, copepods and fish early life stages were the more abundant items, and PERMANOVA analysis showed that the diet differed within the seasons (P(perm) D 0:001) but not between seasons (P(perm) D 0:134).
