A time- and cost-effective strategy to sequence mammalian Y Chromosomes: an application to the de novo assembly of gorilla Y 

Tomaszkiewicz, Marta; Rangavittal, Samarth; Cechova, Monika; Campos Sánchez, Rebeca; Fescemyer, Howard W.; Harris, Robert; Ye, Danling; O'Brien, Patricia C.M.; Chikhi, Rayan; Ryder, Oliver A.; Ferguson Smith, Malcolm A.; Medvedev, Paul; Makova, Kateryna D.; Campos Sánchez, Rebeca (2016-02)
The mammalian Y Chromosome sequence, critical for studying male fertility and dispersal, is enriched in repeats and palindromes, and thus, is the most difficult component of the genome to assemble. Previously, expensive ...

Selvamicin, an atypical antifungal polyene from two alternative genomic contexts 

Van Arnam, Ethan B.; Ruzzini, Antonio C.; Sit, Clarissa Sau-Wei; Horn, Heidi A.; Pinto Tomás, Adrián A.; Currie, Cameron Robert; Clardy, Jon (2016-11-15)
The bacteria harbored by fungus-growing ants produce a variety of small molecules that help maintain a complex multilateral symbiosis. In a survey of antifungal compounds from these bacteria, we discovered selvamicin, an ...

Copulation behaviour of Glossina pallidipes (Diptera: Muscidae) outside and inside the female, with a discussion of genitalic evolution 

Briceño Lobo, Daniel; Eberhard Chabtree, William G.; Robinson, A. S. (Bulletin of Entomological Research (2007) 97, 1–18, 2007-04-26)
If species-specific male genitalia are courtship devices under sexual selection by cryptic female choice, then species-specific aspects of the morphology and behaviour of male genitalia should often function to stimulate ...

Decisions during courtship by male and female medflies (Diptera, Tephritidae): Correlated changes in male behavior and female acceptance criteria in mass-reared flies 

Briceño Lobo, Daniel; Eberhard Chabtree, William G. (Florida Entomologist 85(1):14-31. 2002, 2002-12)
Análisis de más de 300 cortejos video-grabados de moscas del Mediterráneo silvestres y criadas en masas de Costa Rica demostraron que la tendencia de los machos y las hembras de alinearse cara a cara el uno frente al otro ...

Experimental demonstration of possible cryptic female choice on male tsetse fly genitalia 

Briceño Lobo, Daniel; Eberhard Chabtree, William G. (J. Insect Physiol. 2009 Nov; 55(11): 989-996, 2009)
A possible explanation for one of the most general trends in animal evolution – rapid divergent evolution of animal genitalia – is that male genitalia are used as courtship devices that influence cryptic female choice. ...

Experimental modifications imply a stimulatory function for male tsetse fly genitalia, supporting cryptic female choice theory 

Eberhard Chabtree, William G.; Briceño Lobo, Daniel (THE AUTHORS. J. EVOL. BIOL. 22 (2009) 151 6-1525 JOURNAL COMPILATION, 2009)
One of the most sweeping of all patterns in morphological evolution is that animal genitalia tend to diverge more rapidly than do other structures. Abundant indirect evidence supports the cryptic female choice (CFC) ...

Comparative Allometry and Sexual Behavior of Four Fruit Fly Species in the Tribe Ceratitidini (Diptera: Tephritidae) 

Briceño Lobo, Daniel; Eberhard Chabtree, William G.; Quilici, S. (Journal of the Kansas entomological society 78(1), 2005, pp. 20-33, 2005)
Sexual dimorphisms in four related species of tephritid flies were shown to be associated with differences in sexual behavior. In two species, Ceratitis capitata and C. catoirii, males and females approach closely head to ...

Courtship behavior of different wild strains of Ceratitis Capitata (Diptera: Tephritidae) 

Briceño Lobo, Daniel; Eberhard Chabtree, William G.; Vilardi, Juan; Cayol, Jean-Pierre; Shelly, Todd (Florida Entomologist 90(1) March 2007, 2007-03)
Este estudio documenta diferencias en el comportamiento de cortejo de cepas silvestres de Ceratitis capitata (Wied.) provenientes de Madeira (Portugal), Hawaii (Estados Unidos de Norte América), Costa Rica y Patagonia ...

Abundancia, biomasa y floración de Thalassia testudinum (Hydrocharitaceae) en el Caribe de Costa Rica 

Nielsen Muñoz, Vanessa; Cortés Núñez, Jorge (Rev. Biol. Trop. (Int. J. Trop. Biol. ISSN-0034-7744) Vol. 56 (Suppl. 4): 175-189, December 2008, 2008-12)
Three Thalassia testudinumseagrass beds were studied at Cahuita National Park, from August 2003 to August 2006. Additionally, biomass samples of this species were collected at the Gandoca-Manzanillo National Wildlife Refuge, ...
