Biosurveillance for an invasive pest of maize, Prostephanus truncatus, across North America and in Greece por Quellhorst, Hannah E., Sakka, Maria K., Odjo, Sylvanus, Ludwick, Dalton, Bingham, Georgina V., Roeder, Karl A., Hesler, Louis S., Hanley, Raina M., Zhu, Junwei J., Wilkins, Rachel V., Ponce, Marco A., Athanassiou, Christos G., Kun Yan Zhu, Gerken, Alison R., Morrison III, William R.

“…In this study, we performed a 2-year latitudinal biosurveillance programme for P. truncatus, related bostrichids and Sitophilus spp. as key species in and around maize and wheat production at 10-15 sites from 20 degrees to 47 degrees latitude in North America and Greece to evaluate how habitat, latitude and season affected spatiotemporal dynamics of these insects. …”

The influence of environmental variations on the phenolic compound profiles and antioxidant activity of two medicinal Patagonian valerians (Valeriana carnosa Sm. and V. clarionifol... por Nagahama, Nicolas, Gastaldi, Bruno, Clifford, Michael, Manifesto, Maria Marcela, Fortunato, Renee Hersilia

“…In V. carnosa total phenolic content was not correlated with altitude or latitude (p > 0.05), and chemical variability seems to be associated with genetic variability and/or different growing habitats (microclimatic conditions). …”

Crop-photoperiodism model 2.0 for the panicle-initiation date of sorghum and rice that includes daily changes in sunrise and sunset times por Clerget, B., Sidibe, M., Bueno, C.S., Trouche, G., Chantereau, J., Grenier, C., Kawakata, T., Domingo, A.J., Layaoen, H.L., Palacios, N.G., Bernal, J.H.

“…However, questions remain regarding flowering dates in the natural environment, such as the synchronous flowering of plants sown simultaneously at highly contrasting latitudes. The daily change in sunrise and sunset times is the cue for the flowering of trees and for the synchronisation moulting in birds at the equator. …”

ABA and raffinose as key factors in tolerance to low temperature stress in Citrus rootstocks por Primo-Capella, Amparo, Forner-Giner, María A., Martínez-Cuenca, Mary-Rus, Catala-Senent, Laura, Terol, Javier

“…The Citrus genus comprises a number of sensitive tropical and subtropical species to cold stress, which limits global citrus distribution to certain latitudes and causes major economic loss. We used RNA‐Seq technology to analyze changes in the transcriptome of Valencia delta seedless orange in response to long‐term cold stress grafted on two frequently used citrus rootstocks: Carrizo citrange (CAR), considered one of the most cold‐tolerant accessions; C. macrophylla (MAC), a very sensitive one. …”

Intercropping with cassava in Africa por Ezeilo, W.N.

“…In Africa, cassava-growing areas are located from Senegal in the west, through Nigeria and Zaire, east to Malagasy and from 15°N-15°S latitude, according to de Viliers (1965). Optimum production requires an annual rainfall of 1000-2000 mm; average annual temperatures of 25-29 °C; daylengths not greater than 15 hours; altitudes less than 2000 m above sea level; and freely draining sandy loam soils dominated by oxisols, ultisols, and alfisols. …”

Macroecological patterns of forest structure and allometric scaling in mangrove forests por Rovai, A.S., Twilley, R.R., Castañeda Moya, E., Midway, S.R., Friess, D.A., Trettin, C.C., Bukoski, J.J., Stovall, A.E.L., Pagliosa, P.R., Fonseca, A.L., Mackenzie, R.A., Aslan, A., Sasmito, S.D., Sillanpää, M., Cole, T.G., Purbopuspito, J., Warren, M.W., Murdiyarso, D., Mofu, W., Sharma, S., Tinh, P.H., Riul, P.

“…Similarities in stand structural complexity and cross‐site size–density relationships across multiscale environmental gradients show that resource allocation in mangrove ecosystems is independent of tree size and invariant to species composition or latitude. Mangroves follow a universal fractal‐based scaling relationship that describes biomass allocation for several other terrestrial tree‐dominated communities. …”

“…Northern and southern lineages were identified in each species, and Bayesian clustering revealed their convergence at mid latitudes (42°S). Spatial genetic structure (SGS) also indicated the existence of a genetic discontinuity at these latitudes, which is in agreement with previous data from maternal DNA markers. …”
