Membracis mexicana (Hemiptera: Membracidae) is distributed in four biogeographic provinces of Mexico, field observations indicate that there are different forms of this species but so far it has not been recorded how the different forms are and how they are distributed. The aim of this study was to quantify the phenotypic and genetic variation of M...

Context 1
... length of the helmet (PC2) does not allow us to discern groups, the insects in the populations seem to be distributed homogeneously, with long and short pronotums in all populations. The analysis of canonical variance by the host plant takes away the insects sampled on Sallix bonplandiana from the rest also from Zacapú population ( Figure SM5). The canonical variate 1 (CV1) shows that the size of the dorsal spots are largest in their helmet and is what makes this population different from the others. . ...

... haplotype networks for all four genes ( Figure 4A; Figures SM6 to SM10) and their geographic distribution ( Figure 4B; Figures SM11 to SM15), show large divergence and clear geographic structure. The numbers of each haplotype and the frequency of haplotypes are shown in the Supplementary Material (Figures SM6-SM15; Table SM3). ...

Moreover, this pattern of genetic variation is consistent with two lineages in southeastern and western areas ( Figure 5). The western lineage (Pacific Coast and TMVB provinces) corresponds to helmet types 1 and 2, and the southeast lineage (Mexican Gulf and Yucatan Peninsula provinces) corresponds to helmet type 3. ...

Simple Summary
The box tree moth is an invasive species that originated in Asia. Its presence causes damage by defoliating plants, to the point of causing their death. The presence of silk barriers and threads, covering plants during...
Conformation traits are important in the selection and distinction between horse breeds, but tend to be evaluated subjectively within a breed and cannot be compared between them. The horse shape space model, using a combination of 253 landmarks and semi-landmarks, provides objective information on the shape of a horse photographed from the side tha...
In nature, organisms are exposed to variable environmental conditions that impact their performance and fitness. Despite the ubiquity of environmental variability, substantial knowledge gaps in our understanding of organismal responses to nonconstant thermal regimes remain. In the present study, using zebrafish (Danio rerio) as a model organism, we...
This paper examines Nile tilapia (Oreochromis niloticus) in Sub-saharan Africa, where the expansion of aquaculture farms has resulted in the escape of fish, including Nile tilapia, into natural water bodies. This has led to the mixing of escaped tilapia with native species. To successfully manage and conserve these mixed species, it is important to...
