“…In this study, we confirmed the relationship pattern and dating of the three genera as found in earlier molecular studies [10,15,25,37]. We found that the split between Reticulitermes and Heterotermes þ Coptotermes occurred around 59 Ma (49.9 -69.5 Ma 95% CI), the most recent common ancestor of the clade Heterotermes þ Coptotermes arose 36 Ma (33.9 -40.5 Ma 95% CI), and Coptotermes split from sister Heterotermes species around 24.5 Ma (21.0 -27.8 Ma 95% CI).…”

“…We implemented fossil calibrations as exponential priors on node times (electronic supplementary material, table S4). Some of these dates differ from previous calibrations we used [10,25], which were based on dates reported in Emerson [13]. This is because the ages of certain periods, such as the Oligocene, have been revised over time.…”

Reticulitermes, Heterotermes and Coptotermes form a small termite clade with partly overlapping distributions. Although native species occur across all continents, the factors influencing their distribution are poorly known. Here, we reconstructed the historical biogeography of these termites using mitochondrial genomes of species collected on six continents. Our analyses showed that Reticulitermes split from Heterotermes þ Coptotermes at 59.5 Ma (49.9 -69.5 Ma 95% CI), yet the oldest split within Reticulitermes (Eurasia and North America) is 16.1 Ma (13.4 -19.5 Ma) and the oldest split within Heterotermes þ Coptotermes is 36.0 Ma (33.9 -40.5 Ma). We detected 14 disjunctions between biogeographical realms, all of which occurred within the last 34 Ma, not only after the break-up of Pangaea, but also with the continents in similar to current positions. Land dispersal over land bridges explained four disjunctions, oceanic dispersal by wood rafting explained eight disjunctions, and human introduction was the source of two recent disjunctions. These wood-eating termites, therefore, appear to have acquired their modern worldwide distribution through multiple dispersal processes, with oceanic dispersal and human introduction favoured by the ecological traits of nesting in wood and producing replacement reproductives.

“…These species are the most divergent pair in Drosophila known to form a hybrid zone; indeed, similarly diverged pairs produce inviable or sterile hybrids in the laboratory (e.g., D. melanogaster-D. simulans hybrids, Ks = 0.10, [22]). At least two cases of stable, insect hybrid zones between species with more extreme levels of divergence have been reported: multiple parallel hybrid zones occur between color pattern races of Heliconius erato and H. melpomene whose genomes differ extensively (K S = 0.15) [38], and two species of termites (Blattodea: Coptotermes ) estimated to have diverged 17 million years ago (mya) show little evidence of premating RI and produce hybrid colonies [39]. Hybrid zones between highly diverged vertebrate species seem more common [40,41].…”

A Maladaptive Combination of Traits Contributes to the Maintenance of a Drosophila Hybrid Zone

Drosophila teissieri and D. yakuba diverged approximately 3 mya and are thought to share a large, ancestral, African range [1-3]. These species now co-occur in parts of continental Africa and in west Africa on the island of Bioko [1, 4]. While D. yakuba is a human commensal, D. teissieri seems to be associated with Parinari fruits, restricting its range to forests [4-6]. Genome data indicate introgression, despite no evidence of contemporary hybridization. Here we report the discovery of D. yakuba-D. teissieri hybrids at the interface of secondary forests and disturbed, open habitats on Bioko. We demonstrate that hybrids are the F progeny of D. yakuba females and D. teissieri males. At high temperatures like those found on Bioko, D. teissieri females are generally less receptive to mating, and in combination with temperature effects on egg lay and egg-to-adult viability, this decreases the potential for gene flow between female D. teissieri and male D. yakuba relative to the reciprocal cross. Field and laboratory experiments demonstrate that F hybrids have a maladaptive combination of D. yakuba behavior and D. teissieri physiology, generating additional barriers to gene flow. Nevertheless, analysis of introgressed and non-introgressed regions of the genome indicate that, while rare, gene flow is relatively recent. Our observations identify precise intrinsic and extrinsic factors that, along with hybrid male sterility, limit gene flow and maintain these species. These data contribute to a growing body of literature that suggests the Gulf of Guinea may be a hotspot for hybridization.

Red Meranti (Shorea leprosula Miq.) have been widely planted in secondary forests and logged over forest. Problems were found in the field is due to the presence of Coptotermes sp. termite attack in S. leprosula plants resulting to its death. The aims of this study were to determine the percentage and intensity of Coptotermes sp. termite attack. The method used is to perform observations of termite attack in several locations planting, i.e. in KHDTK Samboja (East Kalimantan), KHDTK Sebulu (East Kalimantan), PT INHUTANI II, Pulau Laut (South Kalimantan) and PT Suka Jaya Makmur (West Kalimantan). The results showed that the percentage and intensity of Coptotermes sp. termite attacks in KHDTK Samboja, respectively 7.3% and 4.7%, in KHDTK Sebulu 11.3% and 8.2%, in Inhutani II 5.8% and 5.3% and in PT Suka Jaya Makmur 5.4% and 4.8%. The source of termite attacks in plants in KHDTK Samboja and KHDTK Sebulu was the termite nest contained in secondary forest bordering S. leprosula plantations while the source of the termite attack in plants in Inhutani II and PT Suka Jaya Makmur was the termite nests located between S. leprosula plantations. Finally, Coptotermes sp termite attack disturbed S. leprosula plantation.
