“…In this study, family Nymphalinae was confined to 1,400 m sampling position, probably explained by its preference to higher altitude environments, usually characterised by low temperatures (Freitas, Francini, Paluch, & Barbosa, ).…”

To evaluate the role of altitude on distribution pattern and diversity of entomofauna on miombo woodlands, four altitudes (850, 1,000, 1,250 and 1,400 m) were selected in a characteristic mountainous forest of Inhamacari in Mozambique in July 2015. In each sampling altitude, a linear transect with 16 yellow pan traps spaced 2 m apart was established for insect capture. Capture results allowed assessment of insect distribution by determination of insect abundance and relative frequency. Insect diversity estimates were determined by Shannon–Wiener and Simpson indices. Altitude similarity was assessed by the Jaccard coefficient. The chi‐square test (χ0.052) was used to compare insect abundance and distribution along the altitudinal gradient. Altitude significantly affected insect abundance, relative frequency and distribution, with a nonlinear decrease with increasing altitude. Families Formicidae (Hymenoptera) and Cecidomyiidae (Diptera) were most dominant. Highest diversity and more families confined to unique altitudinal positions were found at 1,250 m while the lowest diversity was observed at 1,000 m.a.s.l. Among the altitudes, greater similarity was found between 1,000 and 1,400 m. In conclusion, altitude had a significant effect on insect family's distribution. However, further research is recommended in order to understand effect of vegetation composition and structure on insect diversity at different altitudes.

“…Using genomic markers, we were able to evaluate the effect of the present disjunct distribution on different mountain ranges in the population genomic structure in both species. Based on the morphological differences of A. mantiqueira and A. alalia and on the results reported for other species of the MAF that present similar distributions, a well-defined genetic structure between these two species is expected, which would also indicate that the São Paulo subtropical gap also functions as geographic barrier for MAF butterflies (do Amaral et al, 2021;Freitas et al, 2018;Thom et al, 2020).…”

The mountains in the Atlantic Forest domain are environments that harbor a high biodiversity, including species adapted to colder climates that were probably influenced by the climatic variations of the Pleistocene. To understand the phylogeographic pattern and assess the taxonomic boundaries between two sister montane species, a genomic study of the butterflies Actinote mantiqueira and A. alalia (Nymphalidae: Acraeini) was conducted. Analyses based on partial sequences of the mitochondrial gene COI (barcode region) failed to recover any phylogenetic or genetic structure discriminating the two species or sampling localities. However, single nucleotide polymorphisms gathered using Genotyping‐by‐Sequencing provided a strong isolation pattern in all analyses (genetic distance, phylogenetic hypothesis, clustering analyses, and FST statistics) which is consistent with morphology, separating all individuals of A. alalia from all populations of A. mantiqueira. The three sampled mountain ranges where A. mantiqueira populations occur—Serra do Mar, Serra da Mantiqueira, and Poços de Caldas Plateau—were identified as three isolated clusters. Paleoclimate simulations indicate that both species' distributions changed according to climatic oscillations in the Pleistocene period, with the two species potentially occurring in areas of lower altitude during glacial periods when compared to the interglacial periods (as the present). Besides, a potential path between their distribution through the Serra do Mar Mountain range was inferred. Therefore, the Pleistocene climatic fluctuation had a significant impact on the speciation process between A. alalia and A. mantiqueira, which was brought on by isolation at different mountain summits during interglacial periods, as shown by the modeled historical distribution and the observed genetic structure.

“…Using these genomic markers, we were able to evaluate the effect of disjunct distribution on different mountain ranges in the population genomic structure in butterflies of the Montane Atlantic Forest. Based on the phenotypic description of the species A. mantiqueira and on the results observed for other species of the MAF that present distributions similar to those of these butterflies, we expect a well-defined genetic structure among the described species, which would suggest that the São Paulo subtropical gap also functions as a geographic barrier for MAF butterflies André Victor Lucci Freitas et al, 2018;.…”

“…In the Montane Atlantic Forest (MAF), there are seven known species of Actinote that participate in a Müllerian mimicry ring named "orangish-red mimicry complex" André Victor Lucci Freitas et al, 2018). The species in this complex are characterized by a dark orange and brown dorsal striped pattern, with a ventral design that is somewhat variable among species.…”

“…The species in this complex are characterized by a dark orange and brown dorsal striped pattern, with a ventral design that is somewhat variable among species. The butterflies of the orangish-red mimicry complex, including Actinote alalia and A. mantiqueira, are morphologically remarkably similar and difficult to distinguish due to the strong similarities in wing pattern, mainly concerning female wing color design, and high intraspecific variation (D 'Almeida, 1935;André Victor Lucci Freitas et al, 2018;. This orangish-red pattern is observed in eight known Actinote species and six share a close common ancestor and are endemic to the MAF .…”
