Ready, Wilsea M. B. de Figueiredo Ready, Joseph C. Waddell, Jonas A. de Oliveira, Cleusa Y. Nagamachi, Cleusa Y. Nagamachi

“…We found a strong phylogenetic signal for chromosome number and noted that sympatric species have exclusive karyotypes. Additional insights into the role of chromosome changes in the diversification of Brachyhypopomus are discussed.…”

HIV infection disrupts the sympatric host-pathogen relationship in human tuberculosis. by Lukas Fenner, Matthias Egger, Thomas Bodmer, Hansjakob Furrer, Marie Ballif, Manuel Battegay, Peter Helbling, Jan Fehr, Thomas Gsponer, Hans L Rieder, Marcel Zwahlen, Matthias Hoffmann, Enos Bernasconi, Matthias Cavassini, Alexandra Calmy, Marisa Dolina, Reno Frei, Jean-Paul Janssens, Sonia Borrell, David Stucki, Jacques Schrenzel, Erik C Böttger, Sebastien Gagneux, Swiss HIV Cohort and Molecular Epidemiology of Tuberculosis Study Groups

“…The phylogeographic population structure of Mycobacterium tuberculosis suggests local adaptation to sympatric human populations. We hypothesized that HIV infection, which induces immunodeficiency, will alter the sympatric relationship between M. tuberculosis and its human host. …”

Effect of substrate size on sympatric sand darter benthic habitat preferences by P. A. Thompson, S. A. Welsh, A. A. Rizzo, D. M. Smith

“…To evaluate substrate selection and preference, western and eastern sand darters were collected from the Elk River, West Virginia, one of the few remaining rivers where both species occur sympatrically. In the laboratory, individuals were given the choice to bury into five equally available and randomly positioned substrates ranging from fine sand to granule gravel (0.12–4.0 mm). …”

MHC adaptive divergence between closely related and sympatric African cichlids. by Jonatan Blais, Ciro Rico, Cock van Oosterhout, Joanne Cable, George F Turner, Louis Bernatchez

“…Here, we studied a pair of sympatric Lake Malawi species, Pseudotropheus fainzilberi and P. emmiltos, whose reproductive isolation depends on olfactory communication. …”

Does habitat matter in avoiding predators among sympatric Katydid species? by Chandranshu Tiwari, Swati Diwakar

“…We studied predator evasion among six sympatric katydid species from two habitats namely, grasslands (Conocephalus maculatus, Euconocephalus pallidus, Euconocephalus helleri) and forest understorey (Ducetia assamica, Ducetia rohinii and Mecopoda elongata). …”

Shared pollinators and sequential flowering phenologies in two sympatric cactus species by Erika Arroyo-Pérez, Cecilia Jiménez-Sierra, J. Zavala Hurtado, Joel Flores

“…Background and aims – The reproductive characteristics of sympatric Cactaceae are important because they help to understand interfering or facilitating mechanisms that allow their coexistence. …”

Behavioral modifications lead to disparate demographic consequences in two sympatric species by Evan P. Tanner, Jeremy P. Orange, Craig A. Davis, R. Dwayne Elmore, Samuel D. Fuhlendorf

“…To better understand how adaptive habitat selection during brood rearing influences demographics, we studied the brood survival, attendant parental survival, and space use of two sympatric ground‐nesting bird species, the northern bobwhite (hereafter: “bobwhite”; Colinus virgininanus) and scaled quail (Callipepla squamata). …”

Ambient temperature as a factor contributing to the developmental divergence in sympatric salmonids by Evgeny V. Esin, Grigorii N. Markevich, Nikolai O. Melnik, Dmitriy V. Zlenko, Fedor N. Shkil

“…Here, we study the role of temperature dynamics on the reproductive sites in the early-life divergence and adaptive radiation of the salmonid fish Salvelinus malma dwelling in the Lake Kronotskoe basin (North-East Asia). Local sympatric charr ecomorphs demonstrate strict homing behaviour guiding the preordained distribution along tributaries and, hence, further development under different temperatures. …”

Hybridization in natural sympatric populations of Dermacentor ticks in northwestern North America by A. Araya‐Anchetta, G. A. Scoles, J. Giles, J. D. Busch, D. M. Wagner

Mito-nuclear sequencing is paramount to correctly identify sympatric hybridizing fishes by C. Sousa-Santos, A.M. Pereira, P. Branco, G.J. Costa, J.M. Santos, M.T. Ferreira, C.S. Lima, I. Doadrio, J.I. Robalo

“…Hybridization may drive speciation and erode species, especially when intrageneric sympatric species are involved. Five sympatric Luciobarbus species—Luciobarbus sclateri (Günther, 1868), Luciobarbus comizo (Steindachner, 1864), Luciobarbus microcephalus (Almaça, 1967), Luciobarbus guiraonis (Steindachner, 1866), and Luciobarbus steindachneri (Almaça, 1967)—are commonly identified in field surveys by diagnostic morphological characters. …”
