The Evolution of the Placenta Drives a Shift in Sexual Selection in Livebearing Fish
LETTER doi:10.1038/nature13451 The evolution of the placenta drives a shift in sexual selection in livebearing fish B. J. A. Pollux1,2, R. W. Meredith1,3, M. S. Springer1, T. Garland1 & D. N. Reznick1 The evolution of the placenta from a non-placental ancestor causes a species produce large, ‘costly’ (that is, fully provisioned) eggs5,6, gaining shift of maternal investment from pre- to post-fertilization, creating most reproductive benefits by carefully selecting suitable mates based a venue for parent–offspring conflicts during pregnancy1–4.

These females, however, run the risk of mat- predicts that the rise of these conflicts should drive a shift from a ing with genetically inferior (for example, closely related or dishonestly reliance on pre-copulatory female mate choice to polyandry in conjunc- signalling) males, because genetically incompatible males are generally tion with post-zygotic mechanisms of sexual selection2. This hypoth- not discernable at the phenotypic level10. Placental females may reduce esis has not yet been empirically tested. Here we apply comparative these risks by producing tiny, inexpensive eggs and creating large mixed- methods to test a key prediction of this hypothesis, which is that the paternity litters by mating with multiple males.

We exploit a unique quality of the livebearing fish post-zygotic maternal investment among the embryos and, in extreme family Poeciliidae: placentas have repeatedly evolved or been lost, cases, divert resources from genetically defective (incompatible) to viable creating diversity among closely related lineages in the presence or embryos1–4,6,11. -

(January 2018). 1 1 Native Range and Status in the United States Native Range From Fuller (2018): “This species is confined to a very small area, the Río Ameca basin, on the Pacific Slope of western Mexico (Miller and Fitzsimons 1971).” From Goodeid Working Group (2018): “This species comes from the Pacific Slope and inhabits the Río Ameca and its tributary, the Río Teuchitlán in Jalisco. More habitats in the ichthyological [sic] closely connected Sayula valley have been detected quite recently.” Status in the United States From Fuller (2018): “Reported from Nevada. Records are more than 25 years old and the current status is not known to us. One individual was taken in November 1981 (museum specimen) and another in August 1983 from Rodgers Spring, Nevada (Courtenay and Deacon 1983, Deacon and Williams 1984). Others were seen and not collected (Courtenay, personal communication).” From Goodeid Working Group (2018): “Miller reported, that on 6 May 1982, this species was collected in Roger's Spring, Clark County, Nevada, (pers. comm. to Miller by P.J. Unmack) where it is now extirpated. It had been exposed there with several other exotic species (Deacon [and Williams] 1984).” From FAO (2018): “Status of the introduced species in the wild: Probably not established.” From Froese and Pauly (2018): “Raised commercially in Florida, U.S.A.” Means of Introductions in the United States From Fuller (2018): “Probably an aquarium release.” Remarks From Fuller (2018): “Synonyms and Other Names: butterfly goodeid.” 2 From Goodeid Working Group (2018): “Some hybridisation attempts have been undertaken with the Butterfly Splitfin to solve its relationship. -

A New Key Character in Males of the Family Goodeidae
No. 4976 March 13, 1965 NATURE 1127 BIOLOGY described by Rothschild and Clay•. No fresh or digested blood was seen within the intestinal caeca of live worms. A New Key Character in Males of the Living mature worms are at least 12 mm long when Family Goodeidae (Cyprinodontiformes) extended, and the opisthaptor is 1·7 mm long and 2·3 mm wide when flattened. These measurements are larger than IN the family Goodeidae, unlike the other viviparous those given by Stunkard1, who was working with fixed Cyprinodontiformes, the male anal fin is not modified into and cont racted specimens.

The Influence of Rearing Experience on the Behaviour of an Endangered
BIOLOGICAL CONSERVATION Biological Conservation 122 (2005) 223–230 www.elsevier.com/locate/biocon The influence of rearing experience on the behaviour of an endangered Mexican fish, Skiffia multipunctata Jennifer L. Kelley a, Anne E. Magurran b, Constantino Macı´as-Garcia c,*,1 a School of BEES, University of New South Wales, Sydney, 2052, Australia b School of Biology, Gatty Laboratory, University of St. Andrews, St. Andrews, Fife, KY16 8LB, UK c Instituto de Ecologia, A.P. 70-153, UNAM, 04510, Mexico DF Received 6 October 2003; received in revised form 27 July 2004; accepted 27 July 2004 Abstract Reintroduction projects may fail because captive-reared animals do not possess the behavioural skills required for survival in the wild. Rearing captive-bred animals in semi-natural enclosures prior to release has been used to improve the survival of reintroduced endangered species, but it is unclear how rearing environment influences the development of behaviour. This study examined the effect of rearing conditions on the behaviour of the goodeid Skiffia multipunctata, an endangered species of Mexican fish. Under standard laboratory conditions, the courtship, aggression, boldness and foraging behaviour of fish raised in aquaria was compared to that of fish reared in outdoor ponds. We present initial behavioural descriptions for this species and show that laboratory-reared fish displayed increased courtship, aggression and curiosity towards a novel predator in comparison to their pond-reared counter- parts. Laboratory-reared fish also commenced foraging on a novel food item (Artemia) more rapidly than fish reared outdoors. These findings suggest that captive rearing environments promote the development of behavioural tendencies, such as boldness and aggression, which could be detrimental to the survival of reintroduced individuals. -

Osteology and Phylogeny of Oviparous Cyprinodont
Osteology and Phylogeny of Oviparous Cyprinodont Fishes (Order Cyprinodontiformes) By RAM PRAKASH SETHI A DISSERTATION PRESENTED TO THE GRADUATE COUNCIL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA January, I960 ACKNOWLEDGMENTS It has been a long cherished dream of mine to be able to pursue graduate studies in the United States. For making this dream come true by providing me a Graduate Assistantship, I am extremely grateful to the Biology Department and the Graduate School of the University of Florida. The assistantship not only helped me financially and academically but also enabled me to come in contact with many friendly American students with whom I had the opportunity of exchanging ideas on numerous topics. Although lacking appropriate words to express the debt of gratitude which I owe to Dr. John D. Kilby, present chairman, and to Dr. Arnold B. Grobman, ex-chairman of my committee, I wish to thank them both for constant guidance and encouragement during the course of this study. Dr. Kilby originally suggested this problem to me and always answered my numerous questions most sympathetically while Dr. Grobman constantly stimulated me to enlarge its horizons. I also wish to thank the other members of my committee, Drs. Lewis Berner, Walter Auffenberg, Ernest S. Ford, and Howard K. Wallace for numerous courtesies, continued interest in my work, and valuable encouragement. Much of the material for this study was obtained from various institutions and a number of individuals have made available specimens or information to me. -
Xenotoca Eiseni (Cyprinodontiformes, Goodeidae) As a Potential New Model for Studies on Maternal Transfer of Environmental Contaminants
Xenotoca eiseni (Cyprinodontiformes, Goodeidae) as a Potential New Model for Studies on Maternal Transfer of Environmental Contaminants Submitted by Simone Monique Tinguely to the University of Exeter as a Thesis for the Degree of Master of Philosophy in Biological Sciences June 2015 This thesis is available for library use on the understanding that it is copyright material and that no quotation from the thesis may be published without proper acknowledgement. I certify that all material in this thesis which is not my own work has been identified and that no material has previously been submitted and approved for the award of a degree by this or any other University. Signature: ………………………………………………………….. 2 Abstract This thesis studies aspects of the reproductive physiology and embryogenesis in the viviparous fish Xenotoca eiseni with a view to increasing the knowledge on its basic biology and development of the species as a model for studying maternal transfer and embryo susceptibility to toxicants. The ontogeny of gonad development was studied via histology to identify sex, stage of gonadal development, structure of the gravid ovary and stage of embryonal development. In males, the testis was comprised of two lobes merged at the anterior end. Spermatogenesis started around four weeks after birth and spermatozeugmata were first seen at between four and eight weeks. In females, there was a single hollow ovary divided into two compartments by a highly folded septum. Oogenesis was first observed between two and four weeks after birth and females reached full sexual maturity at around twelve weeks, when their total body length was at least 3 cm. -
