Centro de Sismología y Volcanología de Occidente (CA-UdG-276 SisVOc), Centro 4 Universitario de la Costa, Universidad de Guadalajara, Puerto Vallarta, México. 5 Abstract 6 The Jalisco region in western Mexico is one of the most seismically active in 7 the country. The city of Puerto Vallarta is located at Bahía de Banderas on the 8 northern coast of Jalisco., Currently there exists a Seismic Gap in the Northern 9 coast of Jalisco (Vallarta Gap). Historically seismogenic tsunamis have affected 10 the coast of Jalisco. In this work, the risk due to a local tsunami in the city of 11 Puerto Vallarta is a function of the interaction between hazard and 12 vulnerability. We model the tsunami hazard, generation and propagation, using 13 the initial conditions for a great earthquake (Mw ≥ 8.0) similar to those that 14 occurred in 1787 at Oaxaca and in 1995 at Tenacatita Bay, Jalisco.

  • Nature Birds of Puerto Vallarta
    Brought to you as a courtesy by Puerto Vallarta Tours NATURE BIRDS OF PUERTO VALLARTA West-Mexican Chachalaca (Ortalis poliocephala) By Petr Myska - May 2006 This loud and raucous member of Cracid family can only be found on Pacific Slope of Western Mexico from Jalisco to Chiapas. It is a relative of guans and curassows rather than of a turkey, for which it is commonly mistaken. Although not very colorful, this species cannot be overlooked when vocalizing. Its gruff, throaty, rhythmic chattering, usually performed by several animals at the same time can be heard from a long distance and is an easy giveaway of the birds’ location. Tied principally to the tropical forest surrounding the Bay of Banderas, it can also be occasionally spotted in green suburban areas. Chachalacas usually travel in groups of up to 10 individuals. Rarely seen on ground they prefer to move in the forest canopy, where they feed on vegetable matter, especially fruit. Nesting is not something Chachalacas are too fussy about. Their nests Puerto Vallarta Hiking and Birdwatching Tours http://www.puertovallartatours.net/hiking.htm resemble flimsy platforms made of leaves and twigs, placed in a tree or a bush. Usually 2-3 eggs are laid. In the Bay area, this species can be found almost throughout. Populations of this endemic bird have been suffering from habitat destruction in the area as well as from poaching.

    Alarcón-Ortega et al. Marine Biodiversity Records (2017) 10:9 DOI 10.1186/s41200-017-0112-3 MARINERECORD Open Access Distribution and species richness of caprellids (Crustacea: Amphipoda) from the Mexican Pacific Lucy Coral Alarcón-Ortega†, Amílcar Leví Cupul-Magaña*, Alma Paola Rodríguez-Troncoso† and Fabio Germán Cupul-Magaña Abstract Background: The caprellid fauna from different localities along the Mexican Pacific coast: Sinaloa (3), Nayarit (15), Jalisco (9) and Colima (1) are presented herein. Methods: A total of 1,093 specimens associated with diverse substrates (octocorals, hydroids, algae, coral rubble and sponge) were recorded. Results: Eight species in four genera were identified: Aciconula acanthosoma Chess 1989; Caprella mendax Mayer 1903; Caprella pitu Sánchez-Moyano, García-Ascencio and Guerra-García 2014; Caprella suprapiscis Galván-Villa and Ayón-Parente 2015; Paracaprella carballoi Sánchez-Moyano, García-Ascencio and Guerra-García 2014; Paracaprella isabelae Sánchez-Moyano, García-Ascencio and Guerra-García 2014; Paracaprella pusilla Mayer 1890; and Liropus isabelensis Sánchez-Moyano, García-Ascencio and Guerra-García 2014. Conclusions: The new records increase the known species richness in the region at local level, including extensions of the known ranges for all the species. These results highlight the need for a large scale survey along the Mexican Pacific coast, along with a more thorough sampling on a large number of substrata, in order to increase the knowledge of caprellid diversity in the area.

  • Thamnophis Rossmani Conant, 2000. Rossman's Gartersnake Is the Only
    Thamnophis rossmani Conant, 2000. Rossman’s Gartersnake is the only herpetofaunal species endemic to Nayarit. Its distribution is restricted to the vicinity of the type locality, 1.4 km NW of the small settlement of San Cayetano, Nayarit, Mexico (Conant, 2000), which lies between the capital city of Tepic and the town of San Cayetano (ca. 10 km SE of Tepic). Douglas A. Rossman collected the holotype in 1969. Conant (2000) noted that suitable habitat for T. rossmani may have existed in this area before the region was disturbed for agriculture, and indicated that the localities he visited in 1959 were drastically altered; he also noted (p. 5) that T. rossmani “may be in grave danger, if not already extinct.” Pictured here is an individual from Pantanal, in the municipality of Xalisco. Importantly, Nayarit’s single state endemic is not found within a Natural Protected Area (Ponce-Campos and García-Aguayo, 2007), and occurs in an area likely to be overrun by urbanization. Wilson et al. (2013a) calculated its EVS as 18, placing it in the upper portion of the high vulnerability category. Its conservation status has been considered as Data Deficient by IUCN; this species is not listed by SEMARNAT.
