Data from: Grassland type and seasonal effects have a bigger influence on plant functional and taxonomical diversity than prairie dog disturbances in semi-arid grasslands

Maria Gabriela Rodriguez Barrera, Ingolf Kühn, Eduardo Estrada-Castillón & Anna Cord
Prairie dogs (Cynomys sp.) are considered keystone species and ecosystem engineers for their grazing and burrowing activities (summarized here as disturbances). As climate changes and its variability increases, the mechanisms underlying organisms’ interactions with their habitat will likely shift. Understanding the mediating role of prairie dog disturbance on vegetation structure, and its interaction with environmental conditions through time, will increase knowledge on the risks and vulnerability of grasslands. Here, we compared how plant taxonomical diversity,...

Data from: Predation drives morphological convergence in the Gambusia panuco species group among lotic and lentic habitats

Eric K. Moody & M.L. Lozano-Vilano
Fish morphology is often constrained by a trade-off between optimizing steady vs. unsteady swimming performance due to opposing effects of caudal peduncle size. Lotic environments tend to select for steady swimming performance, leading to smaller caudal peduncles, while predators tend to select for unsteady swimming performance, leading to larger caudal peduncles. However, it is unclear which aspect of performance should be optimized across heterogeneous flow and predation environments and how this heterogeneity may affect parallel...

Data from: Worldwide patterns of genetic differentiation imply multiple \"domestications\" of Aedes aegypti, a major vector of human diseases

Julia E. Brown, Carolyn S. McBride, Petrina Johnson, Scott Ritchie, Christophe Paupy, Hervé Bossin, Joel Lutomiah, Ildefonso Fernandez-Salas, Alongkot Ponlawat, Anthony J. Cornel, William C. Black, Norma Gorrochotegui-Escalante, Ludmel Urdaneta-Marquez, Massamba Sylla, Michel Slotman, Kristy O. Murray, Christopher Walker, Jeffrey R. Powell & W. C. Black
Understanding the processes by which species colonize and adapt to human habitats is particularly important in the case of disease-vectoring arthropods. The mosquito species Aedes aegypti, a major vector of dengue and yellow fever viruses, probably originated as a wild, zoophilic species in sub-Saharan Africa, where some populations still breed in tree holes in forested habitats. Many populations of the species, however, have evolved to thrive in human habitats and to bite humans. This includes...

UCE alignments and phylogenetic trees

Christopher Blair, Robert Bryson, Uri Garcia-Vazquez, Adrian Nieto-Montes De Oca, David Lazcano, John McCormack & John Klicka
Genomic data continue to advance our understanding of species limits and biogeographic patterns. However, there is still no consensus regarding appropriate methods of phylogenomic analysis that make the best use of these heterogeneous data sets. In this study, we used thousands of ultraconserved element (UCE) loci from alligator lizards in the genus Gerrhonotus to compare and contrast species trees inferred using multiple contemporary methods and provide a timeframe for biological diversification across the Mexican Transition...

Data from: Larval density mediates knockdown resistance to pyrethroid insecticides in adult Aedes aegypti

Marissa K. Grossman, Valentin Uc-Puc, Adriana E. Flores, Pablo C. Manrique-Saide & Gonzalo M. Vazquez-Prokopec
Background: Understanding mechanisms driving insecticide resistance in vector populations remains a public health priority. To date, most research has focused on the genetic mechanisms underpinning resistance, yet it is unclear what role environmental drivers may play in shaping phenotypic expression. One of the key environmental drivers of Aedes aegypti mosquito population dynamics is resource-driven intraspecific competition at the larval stage. We experimentally investigated the role of density-dependent larval competition in mediating resistance evolution in Ae....

Maternal sweeteners intake modulates gut microbiota and exacerbates learning and memory processes in adult male offspring

Ana Laura De La Garza
Background: There is increasing evidence that gut microbiota in offspring is derived in part from maternal environment such as diet. Thus, sweeteners intake including caloric or non-caloric, during perinatal period can induce gut dysbiosis and program the offspring to develop cognitive problems later in life. Objective: To determine the effect of maternal high-sweeteners intake during gestation and lactation on gut microbiota shifts in adult male offspring rats and the impact on cognitive dysfunction. Methods: Thirty-four...
