• Copy number variation analysis in the great apes reveals species-specific patterns of structural variation

      Gazave, E.; Darre, F.; Morcillo-Suarez, C.; Petit-Marty, N.; Carreno, A.; Marigorta, U. M.; Ryder, Oliver A.; Blancher, A.; Rocchi, M.; Bosch, E.; et al. (2011)
      ...We performed intraspecific comparative genomic hybridizations to identify loci harboring copy number variants in each of the four great apes: bonobos, chimpanzees, gorillas, and orangutans. For the first time, we could analyze differences in CNV location and frequency in these four species, and compare them with human CNVs and primate segmental duplication (SD) maps....
    • Effects of combination birth control on estrous behavior in captive western lowland gorillas, Gorilla gorilla gorilla

      Sarfaty, A.; Margulis, S.W.; Atsalis, Sylvia (2012)
      Combination birth control pills (CBC) are one of the most common birth control methods used for western lowland gorillas (Gorilla gorilla gorilla) housed in zoos. Since zoos are interested in maintaining as many natural behaviors as possible, it is important to know how contraception may affect social and sexual interactions among group members....
    • Identification of differences in human and great ape phytanic acid metabolism that could influence gene expression profiles and physiological functions

      Watkins, Paul A.; Moser, Ann B.; Toomer, Cicely B.; Steinberg, Steven J.; Moser, Hugo W.; Karaman, Mazen W.; Ramaswamy, Krishna; Siegmund, Kimberly D.; Lee, D. Rick; Ely, John J.; et al. (2010)
      It has been proposed that anatomical differences in human and great ape guts arose in response to species-specific diets and energy demands. To investigate functional genomic consequences of these differences, we compared their physiological levels of phytanic acid, a branched chain fatty acid that can be derived from the microbial degradation of chlorophyll in ruminant guts. Humans who accumulate large stores of phytanic acid commonly develop cerebellar ataxia, peripheral polyneuropathy, and retinitis pigmentosa in addition to other medical conditions. Furthermore, phytanic acid is an activator of the PPAR-alpha transcription factor that influences the expression of genes relevant to lipid metabolism.
    • Information sharing for gorilla conservation: a workshop in Ruhija.

      Imong, I.; Abwe, Ekwoge E.; Ikfuingei, R.; Onononga, J.R.; Makaga, L. (2012)
      Gorilla conservationists and researchers working on the ground at different sites often face the challenge of accessing valuable yet unpublished information about ongoing projects outside their immediate locality, and sharing experiences on their respective projects. Poor information sharing among field workers means that those planning or carrying out projects at one site may not be able to learn from the experiences of others who might have implemented similar projects at other sites.
    • Insights into hominid evolution from the gorilla genome sequence

      Scally, Aylwyn; Dutheil, Julien Y.; Hillier, LaDeana W.; Jordan, Gregory E.; Goodhead, Ian; Herrero, Javier; Hobolth, Asger; Lappalainen, Tuuli; Mailund, Thomas; Marques-Bonet, Tomas; et al. (2012)
      Gorillas are humans’ closest living relatives after chimpanzees, and are of comparable importance for the study of human origins and evolution. Here we present the assembly and analysis of a genome sequence for the western lowland gorilla, and compare the whole genomes of all extant great ape genera....
    • Obituary to Kupe Cowboy

      Morgan, Bethan J. (2020)
      Simon ‘Kupe’ Ngwese, better known as ‘Kupe Cowboy’, lived a full life. Born in around 1940, to a poor family in Kupe village, near Tombel, Kupe-Muanenguba division of South West Region, Cameroon, like many around him he grew up as a farmer and opportunistic hunter. Later in life, he worked as a research assistant to the then San Diego Zoo Global project at Mount Kupe in Bakossiland....
    • Recent decline in suitable environmental conditions for African great apes

      Junker, Jessica; Blake, Stephen; Boesch, Christophe; Campbell, Geneviève; Toit, Louwrens du; Duvall, Chris; Ekobo, Atanga; Etoga, Gilles; Galat-Luong, Anh; Gamys, Joel; et al. (2012)
      To predict the distribution of suitable environmental conditions (SEC) for eight African great ape taxa for a first time period, the 1990s and then project it to a second time period, the 2000s; to assess the relative importance of factors influencing SEC distribution and to estimate rates of SEC loss, isolation and fragmentation over the last two decades....
    • The cryptic genetic structure of the North American captive gorilla population

      Nsubuga, A.M.; Holzman, J.; Chemnick, Leona G.; Ryder, Oliver A.; (2010)
      Western lowland gorillas (Gorilla gorilla gorilla) were imported from across their geographical range to North American zoos from the late 1800s through 1974.... Here, we analyze 32 microsatellite loci in 144 individuals using a Bayesian clustering method to delineate clusters of individuals among a sample of founders of the captive North American zoo gorilla collection....
    • The gorillas of the Ebo Forest, Cameroon

      Morgan, Bethan J.; (2010)
      Cameroon is an important country for both gorillas and chimpanzees. To the south of the Sanaga River, western lowland gorillas (Gorilla gorilla gorilla) exist, often sympatrically with central chimpanzees (Pan troglodytes troglodytes). To the forested region northwest of the Sanaga River the Nigeria-Cameroon chimpanzee (Pan troglodytes vellerosus) is present (Gonder et al. 1997), as well as a small remnant population of Cross River gorillas (Gorilla gorilla diehli) peppered along the Cameroon-Nigerian border area (Morgan & Sunderland-Groves 2004)....
