Preliminary Report Tropical Storm Bud 13 - 17 June 2000
Preliminary Report Tropical Storm Bud 13 - 17 June 2000 Jack Beven National Hurricane Center 21 July 2000 a. Synoptic history The origins of Bud can be traced to a tropical wave that emerged from the coast of Africa on 22 May. The wave generated little convection as it moved across the Atlantic and Caribbean. The wave moved into the eastern Pacific on 6 June, but showed few signs of organization until 11 June when a broad low pressure area formed a few hundred miles southwest of Acapulco, Mexico. The initial Dvorak intensity estimates were made that day. Further development was slow, as the low exhibited multiple centers for much of 11-12 June. As one center emerged as dominant, the system became a tropical depression near 0600 UTC 13 June about 370 n mi south-southwest of Manzanillo, Mexico (Table 1). The depression became Tropical Storm Bud six hours later as it moved northwestward. Bud reached a peak intensity of 45 kt early on 14 June while turning north-northwestward. The peak intensity was maintained for 12 hr, followed by slow weakening due to a combination of increasing vertical shear and cooler sea surface temperatures. Bud passed just northeast of Socorro Island on 15 June as a 40 kt tropical storm. It weakened to a depression on 16 June as it slowed to an erratic drift about 70 n mi north of Socorro Island. Bud dissipated as a tropical cyclone on 17 June about 90 n mi north-northeast of Socorro Island; however, the remnant broad low persisted until 19 June. -

Of Extinct Rebuilding the Socorro Dove Population by Peter Shannon, Rio Grande Zoo Curator of Birds
B BIO VIEW Curator Notes From the Brink of Extinct Rebuilding the Socorro Dove Population by Peter Shannon, Rio Grande Zoo Curator of Birds In terms of conservation efforts, the Rio Grande Zoo is a rare breed in its own right, using its expertise to preserve and breed species whose numbers have dwindled to almost nothing both in the wild and in captivity. Recently, we took charge of a little over one-tenth of the entire world’s population of Socorro doves which have been officially extinct in the wild since 1978 and are now represented by only 100 genetically pure captive individuals that have been carefully preserved in European institutions. Of these 100 unique birds, 13 of them are now here at RGZ, making us the only holding facility in North America for this species and the beginning of this continent’s population for them. After spending a month in quarantine, the birds arrived safe and sound on November 18 from the Edinburgh and Paignton Zoos in England. Other doves have been kept in private aviaries in California, but have been hybridized with the closely related mourning dove, so are not genetically pure. History and Background Socorro doves were once common on Socorro Island, the largest of the four islands making up the Revillagigedo Archipelago in the East- ern Pacific ocean about 430 miles due west of Manzanillo, Mexico and 290 miles south of the tip of Baja, California. Although the doves were first described by 19th century American naturalist Andrew Jackson Grayson, virtually nothing is known about their breeding behavior in the wild. -

ERICKSON, LSA Associates, 20 Executive Park, Suite 200, Irvine, California 92614; [email protected] ABSTRACT: We report 56 bird specimens of 31 species taken on Isla Guadalupe, Baja California, between 1986 and 2004 and housed at the Colección Ornitológica del Laboratorio de Vertebrados de la Facultad de Ciencias, Universidad Autónoma de Baja California, Ensenada, along with other sight and specimen records. The speci- mens include the first published Guadalupe records for 10 species: the Ring-necked Duck (Aythya collaris), Long-billed Curlew (Numenius americanus), Bonaparte’s Gull (Larus philadelphia), Ash-throated Flycatcher (Myiarchus cinerascens), Warbling Vireo (Vireo gilvus), Tree Swallow (Tachycineta bicolor), Yellow Warbler (Dendroica petechia), Magnolia Warbler (Dendroica magnolia), Yellow-headed Blackbird (Xan- thocephalus xanthocephalus), and Orchard Oriole (Icterus spurius). A specimen of the eastern subspecies of Brown-headed Cowbird (Molothrus ater ater) and a sight record of the Gray-cheeked Thrush (Catharus minimus) are the first reported from the Baja California Peninsula (and islands). A photographed Franklin’s Gull (Larus pipixcan) is also an island first. Currently 136 native species and three species intro- duced in North America have been recorded from the island and nearby waters. -

Behavioural Responses of White Sharks to Specific Baits During Cage
www.nature.com/scientificreports OPEN Behavioural responses of white sharks to specifc baits during cage diving ecotourism Edgar E. Becerril‑García1,2, Edgar M. Hoyos‑Padilla2,3*, Primo Micarelli4, Felipe Galván‑Magaña1 & Emilio Sperone5 This study describes the efect of diferent baits on the attraction, surface behaviour and conditioning of white sharks Carcharodon carcharias during local ecotourism activities. The sightings, behaviours, and pictures used for photographic identifcation were obtained during August to November 2012– 2014 onboard tourist boats in Guadalupe Island, Mexico. Four types of baits were used: (1) frozen bait; (2) frozen bait and natural chum; (3) fresh fsh bait; and (4) mackerel bags. Data were analysed according to sex, maturity and the total of sharks using 6,145 sightings of 121 white sharks. The type of bait showed no signifcant diference on the efectiveness to attracting sharks. Ethological analysis showed that the type of bait had a signifcant efect on the shark’s surface behaviour during its interactions with boats. Natural chum and fresh baits showed short term behavioural patterns constituted by increased number of violent interactions with the bait, while the frozen bait did not generate a defned behavioural pattern. Conditioning of white sharks was determined by the number of interactions and the consumption frequency of the bait. Fifty nine percent of sharks (n = 41) showed no conditioning, 36% (n = 25) showed a low risk and only 5% (n = 3) were found to have a high risk of conditioning. The results suggest that current ecotourism has no efect on the conditioning of the white sharks, and that all baits have a similar efectiveness for attracting the sharks. -

Pacific Seabird Program Business Plan (Dawson Et Al
National Fish and Wildlife Foundation Business Plan for Pacific Seabirds (Update) September 2016 Pacific Seabirds | 1 Purpose of a Business Plan The purpose of a NFWF business plan is to provide a detailed blueprint of the strategies and resources required to achieve the desired conservation outcomes. The strategies discussed in this plan do not represent solely the Foundation’s view of the actions necessary to achieve the identified conservation goals, but instead reflect the majority view of the many federal, state, academic, and organizational experts that were consulted during plan development. This plan is not meant to duplicate ongoing work but rather to invest in areas where gaps might exist so as to support the efforts of the larger conservation community. Acknowledgements We thank everyone who contributed to this business plan. We are especially grateful to the seabird experts, funding partners, and working group teams who took the time to develop, contribute, and review material. We acknowledge the contributions of Dantzker Consulting, Advanced Conservation Strategies, and Clarus Research for their evaluation of the Pacific Seabird Program and recommendations for continued implementation of this program. We also wish to acknowledge the valuable input resulting from discussions and written material provided by implementation and funding partners including (but not limited to): The American Bird Conservancy, BirdLife International, The David and Lucille Packard Foundation, The Farallon Institute, Island Conservation, the National Audubon Society, National Park Service, National Oceanographic and Atmospheric Administration, Oikonos, University of California Santa Cruz Coastal Conservation Action Lab, The University of Washington, The U.S. Fish and Wildlife Service, The U.S. -

FARMERI, MARIA C. FARMER2 and RAINER BERGER3 ABSTRACT. Extensive eruptions of alkalic basalt from low-elevation fissures and vents on the southern flank of the dormant volcano, Cerro Evermann, accompanied the most recent phase of volcanic activity on Socorro Island, and created 14C the Lomas Coloradas, a broad, gently sloping terrain comprising the southern part of the island. We obtained ages of 4690 ± 270 BP (5000-5700 cal BP) and 5040 ± 460 BP (5300-6300 cal BP) from lacustrine deposits that occur within volcanic sequences of the lower Lomas Coloradas. Apparently, the sediments accumulated within a topographic depression between two scoria cones shortly after they formed. The lacustrine environment was destroyed when the cones were breached by headward erosion of adjacent stream drainages. -
