Hypoxia and cold temperatures create unique physiological challenges for high-altitude organisms that can vary depending on lifestyle. While nearly all studies of air-breathing animals at high altitude are from terrestrial species, species that breath-hold dive underwater at high altitude encounter a very different set of selective pressures influencing their phenotype. The goal of this publication is to highlight the changes in O2 transport and utilization in high-altitude diving birds relative to divers at sea level, and the extent to which these changes are qualitatively distinct from phenotypic changes in non-diving species at high altitude. For example, while high capacities for …

History, Annotated Gazetteer, And Bibliography Of Sarawak Ornithology, Frederick H. Sheldon, Dency F. Gawain, Daisy G. S. Kho, Rosalina Regai, Subir B. Shakya, Chin Aik Yeap

Occasional Papers of the Museum of Natural Science, Louisiana State University

Sarawak is Malaysia’s largest state, covering most of northern Borneo. It has a remarkable history of scientific bird study, starting in the 1840s and growing ever since. To set the stage for the gazetteer, which is the core of this paper, we start with a review of this history and discuss various forces that have influenced the direction of bird research in the state. Following this introduction comes the gazetteer, which is an annotated list of c. 865 sites in Sarawak where birds have been collected, studied, or regularly observed. The gazetteer provides the latitude, longitude, and elevation of each …

Henry V. Howe And His Collection Of Foraminifera At Louisiana State University, Lorene E. Smith, Baren K. Sen Gupta

Occasional Papers of the Museum of Natural Science, Louisiana State University

Henry V. Howe, the founder of the current academic program in geology at Louisiana State University (LSU), and a renowned ostracod specialist, was also a distinguished foraminiferal paleontologist. His best work in that field, involving the discovery of many new species, was on the taxonomy of Eocene Foraminifera of Louisiana. The present H.V. Howe Type Collection of Microfossils began with Howe’s gift of slides to LSU. This collection, enriched by contributions from later workers, now includes over 580 slides of foraminiferal primary type specimens, with holotypes and syntypes of 361 species and 15 taxa labeled as “varieties.” Information regarding these …

Here we provide information on the study-sites and summarize the main discoveries resulting from the collaboration.

A Review Of Current Knowledge Concerning The Breeding And Summer Distribution Of The Cordilleran Flycatcher (Empidonax Occidentalis) In Mexico, Harold F. Greeney, Matthew J. Miller, Charles Van Riper Iii

Occasional Papers of the Museum of Natural Science, Louisiana State University

The Cordilleran Flycatcher (Empidonax occidentalis) is one of many North American birds whose distribution crosses the US–Mexican border and for which little is presently known about summer distribution and breeding biology south of this border. In addition, the Cordilleran Flycatcher presents ornithologists with a number of challenging questions surrounding its taxonomy, migration, distribution, population structure, and species limits. In particular, there remains a good deal of uncertainty concerning the species-level relationships, seasonal movements, and the wintering and breeding distributions of both recognized subspecies of Cordilleran Flycatcher in Mexico. Using field observations, a thorough review of the literature, and …

First Record Of The Non-Native Pacu, Piaractus Brachypomus, In Lago Petén-Itzá, Guatemala, Central America, Diego J. Elias, Susan F. Mochel, Prosanta Chakrabarty, Caleb D. Mcmahan

Occasional Papers of the Museum of Natural Science, Louisiana State University

We documented the first record of the non-native species Piaractus brachypomus (Characiformes: Serrasalmidae) in Lago Petén-Itzá, Petén, Guatemala. One brined specimen was donated by a local fisherman in San Benito, El Petén. The captured specimen was reportedly collected in the southern basin of the lake. We used the mitochondrial gene cytochrome oxidase I (COI) to validate identity of the specimen. We hypothesize that the local aquarium trade is the most likely source of introduction of the non-native Pacu in Lago Petén-Itzá.

First Record Of The Non-Native Suckermouth Armored Catfish Hypostomus Cf. Niceforoi (Fowler 1943) (Siluriformes: Loricariidae) From Central America, Wilfredo A. Matamoros, Caleb D. Mcmahan, Carlos R. Mejia, Parker H. House, Jonathan W. Armbruster, Prosanta Chakrabarty

Occasional Papers of the Museum of Natural Science, Louisiana State University

We document the first record of Hypostomus cf. niceforoi in Central America. Two specimens of these suckermouth armored catfishes were collected in Lake Nicaragua (Nicaragua) and identified as H. cf. niceforoi. Hypostomus niceforoi is endemic to Andean streams of Colombia, Venezuela, Ecuador, and Peru. We hypothesize that its introduction in Central America is related to the aquarium trade, as is the case of other armored catfish species introductions.

Gazetteer And Site-Based History Of The Ornithology Of Sabah. Malaysian Borneo, Frederick H. Sheldon

Occasional Papers of the Museum of Natural Science, Louisiana State University

The gazetteer lists sites in the state of Sabah, Malaysia, where birds have been collected, studied, or watched. Its purpose is to identify locations for research and birding in Sabah and to provide a brief scientific history of the more important sites. Each site description includes latitude, longitude, and general information on location. For many sites, elevation, habitat, scientific or birdwatching importance, historical notes, citations of key papers, specimen records, and records of certain species are also included.

Birds In Peatswamp At Klias Forest Reserve And Environs, Sabah, Malaysian Borneo, Frederick H. Sheldon, Geoffrey Davison, Anna Wong, Robert G. Moyle

Occasional Papers of the Museum of Natural Science, Louisiana State University

Periodically from 1998-2004, we surveyed birds in the Klias Forest Reserve, which is one of the last remaining pockets of peatswamp in western Sabah. We report here on those surveys. We also review prior work on birds in peatswamp and swamp forest in the Klias-Sipitang region of Sabah as it relates to the conservation of habitat and birds specialized on peatswamp. Peatswamp forest is in jeopardy from development and fires throughout Borneo, and particularly in the Malaysian State of Sabah, which had very little to start. Peatswamp in the Klias area is of particular importance for conservation and bird watching …

Occasional Papers of the Museum of Natural Science, Louisiana State University

Notes on the avifauna of the floodplain forest of the Rio Mamoré, Beni, Bolivia, with a description of the Juvenile plumage of Unicolored Thrush (Turdus haplochrous) – The floodplain forest along the Rio Mamoré is an isolated stretch of riverine forest in the matrix of flooded grassland and gallery forest of the Llanos de Moxos in the department of Beni, Bolivia and contains an understudied avifauna. This habitat potentially represents a stronghold for certain bird taxa. During Dec 2010-Jan 2011, we conducted daily audiovisual censuses, targeted collecting with shotguns, and general collecting with mist-nets for birds at a …

Notes On Bird Species In Bamboo In Northern Madre De Dios, Peru, Including The First Peruvian Record Of Acre Tody-Tyrant (Hemitriccus Cohnhafti), Michael G. Harvey, Daniel F. Lane, Justin Hite, Ryan S. Terrill, Sheila Figueroa Ramírez, Brian Tilston Smith, John Klicka, Walter Vargas Campos

Occasional Papers of the Museum of Natural Science, Louisiana State University

In the southwestern Amazon Basin, large areas of habitat are comprised predominantly of Guadua bamboo. Many bird species occur in or specialize on Guadua-dominated habitats, but little is known about the taxonomy, distribution, and evolutionary history of this avian assemblage. During 2011, we surveyed the surroundings of Iberia, an area with many large Guadua stands in the southern Peruvian Amazon. We found many Guadua specialist bird species and discovered a surprising Andean element to the local avifauna. We present information on Guadua specialists, Andean species, birds of open habitats, and avian migration and reproduction. We provide accounts for species …

Species Limits Within The Mexican Garter Snakes Of The Thamnophis Godmani Complex, Douglas A. Rossman, Frank T. Burbrink

Occasional Papers of the Museum of Natural Science, Louisiana State University

The highly variable Thamniphis godmani complex of southern Mexico, comprised of four apparently allopatric populations, was examined by using 28 morphological characters scored on 214 specimens. Character values were tested with univariate and multivariate statistics to determine if populations are morphologically distinct. The results suggest that the four populations represent independently evolving lineages. Four species, three previously undescribed, are recognized in the T. godmani complex. A lectotype is designated for T. godmani. For each species, a diagnosis description of holotype or lectotype, summary of interspecific variation, and statement of distribution are provided. Comparisons are made with T. errans, alleged to …
