“…as well as N. corniger and N. dasyopsis have polycalic arboreal nests with several queens that are interconnected by networks of galleries (Adams, ; Hartke, ; Roisin, ; Roisin & Pasteels, ; Thorne, ; Thorne & Levings, ; Vasconcellos & Bandeira, ; Supporting Information Figure A,B). These attributes allow them to reach large colony sizes (Buschini & Lenonardo, ) that occupy and defend huge territories (Adams & Levings, ; Roisin & Pasteels, ), which makes them ecological dominant (Thorne, ; Vasconcellos & Bandeira, ) and can explain their high abundance in our study.…”

Termites are ecosystem engineers that play an important role in the biotransformation and re‐distribution of nutrients in soil. The dry forests are endemic repositories, but at same time, they are most threatened by extensive livestock and crop farming, fires, and climate change. In Colombia, the best‐protected dry forests are located in the north. The termite fauna of dry forests are poorly known. The aim was to identify the termite species occurring in tropical dry forests of the Colombian Caribbean coast in relation to diet and precipitation, temperature, elevation, and soil properties. A total of 32 species in 1,103 occurrences were found. Termitidae accounted for 78% of the species richness with the Anoplotermes‐group, Microcerotermes, and Nasutitermes being the dominant genera. Differences in species composition and abundance were found across sites. These differences may be linked to anthropogenic disturbance and polygyny and polydomy. Strikingly, our highest elevation site (334 m) had the highest species richness much higher than the two lower elevation sites. This implies an inversion of the common elevation‐diversity gradient, also found for termites which can be explained by increasing precipitation with elevation in the dry forest. An analysis of termite species richness at the global scale confirms that termite species richness correlates positively with rainfall. Hence, rainfall seems to positively affect termite diversity. In line, the studied Colombian tropical dry forests had low diversity compared to rain forests. A decline of species‐rich soil‐feeding termites with increasing aridity may explain why the highest termite diversity occurs in humid tropical rain forests. Abstract in Spanish is available with online material.

Resumo. Este trabalho teve como objetivo analisar a influência da densidade arbórea e da borda sobre a quantidade e o volume nidal dos ninhos arborícolas de Nasutitermes sp., bem como, verificar a dependência do tamanho desses ninhos e a sua região de fixação em relação à arquitetura arbórea. A coleta de dados foi realizada em outubro de 2005, em um trecho da mata ribeirinha do rio Miranda no Pantanal Miranda-Abobral, sendo feita amostragem da quantidade e volume nidal dos ninhos arborícolas de Nasutitermes sp. e verificado a densidade de árvores de dossel através do método de amostragem por parcelas ao longo de um gradiente de profundidade na mata. Outros valores de arquitetura arbórea em que o ninho servia de abrigo também foram analisados, utilizando-se o coeficiente de correlação de Spearman, o teste de Kruskal-Wallis e o Qui-Quadrado. Dentre os resultados analisados, conclui-se que os ninhos arborícolas de Nasutitermes sp. não estão distribuídos ao acaso na mata. Mas sim, pode-se inferir que a quantidade e volume nidal, os locais de fixação, construção e desenvolvimento desses ninhos arborícolas na mata ribeirinha do rio Miranda sofrem interferência da estrutura arbórea da mata estudada. Nasutitermes sp. (Isoptera: Termitidae) Distribution and Density in Riverine Forest of the River Miranda, Pantanal Sul-Matogrossense, Brazil. Abstract. This work had as objectives to analyze the influence of the arboreal density and of the border on the amount and the volumetric mass of the arboreal nests of Nasutitermes sp., and to verify the dependence of the size of those nests and your fixation area in relation to the arboreal architecture. In October of 2005, in a space of the riverine forest of the river Miranda in the Pantanal of the Miranda-Abobral was accomplished the collection of data, being made sampling of the amount and volumetric mass of the arboreal nests of Nasutitermes sp., and verified the density of dossal trees through the sampling method for portions along a depth gradient in the forest. Other values of arboreal architecture in that the nest served as shelter were also analyzed, being used Spearman’s correlation coefficient, Kruskal-Wallis test and Chi-Square. Among the analyzed results, it is ended that the arboreal nests of Nasutitermes sp. are not maybe distributed to the in the forest. But yes, can be inferred that the amount and your volumetric masses, the fixation places, construction and development of those arboreal nests in the riverine forest of the river Miranda suffers interference of the arboreal structure of the studied forest.

The mound- building termite Nasutitermes coxipoensis is commonly found at subtropical environments of northeast Argentina. This study gives new data about its nest architecture, biology and nutritional habits, comparing these results with other populations of the species. The volume of the analyzed nests varied between 0.91 dm3 y 207.33 dm3, a wider range than previously reported for N. coxipoensis. The external and internal characteristics of the nests were similar to descriptions from other sites although it was not possible to differentiate the royal cell. The societies were monogynic and the queens laid eggs throughout the year. The body length and weight of primary reproductives were reported. The presence of alates within the mounds was higher in October and November. Feeding substrates consumed by N. coxipoensis at these habitats are also reported.
