“…Seasonality did not significantly influence the carabid beetle assemblage, even though numerous studies have shown seasonality to be important in dry forest beetles (e.g., Novais et al 2016;Pérez and Zaragoza 2016;Rangel-Acosta and Martínez-Hernández 2017;Noguera et al 2018). However, there are exceptions; for example dung beetle richness differences between wet and dry seasons in the Caatinga forest in Brazil were small (Medina and Lopes 2014).…”

Little is known about the successional dynamics of insects in the highly threatened tropical dry forest (TDF) ecosystem. For the first time, we studied the response of carabid beetles to vegetal succession and seasonality in this ecosystem in Colombia. Carabid beetles were collected from three TDF habitat types in two regions in Colombia: initial successional state (pasture), early succession, and intermediate succession (forest). The surveys were performed monthly for 13 months in one of the regions (Armero) and during two months, one in the dry and one in the wet season, in the other region (Cambao). A set of environmental variables were recorded per month at each site. Twenty-four carabid beetle species were collected during the study. Calosoma alternans and Megacephala affinis were the most abundant species, while most species were of low abundance. Forest and pasture beetle assemblages were distinct, while the early succession assemblage overlapped with these assemblages. Canopy cover, litter depth, and soil and air temperatures were important in structuring the assemblages. Even though seasonality did not affect the carabid beetle assemblage, individual species responded positively to the wet season. It is shown that early successional areas in TDF could potentially act as habitat corridors for species to recolonize forest areas, since these successional areas host a number of species that inhabit forests and pastures. Climatic variation, like the El Niño episode during this study, appears to affect the carabid beetle assemblage negatively, exasperating concerns of this already threatened tropical ecosystem.

“…A dichotomic seasonal (transition between rainy and dry seasons) pattern differentiated by precipitation, has been observed in tropical regions for various groups of insects (Kishimoto-Yamada & Itioka, 2015; Novais et al, 2016) and for different families of beetles in the TDF (Toledo-Hernández et al, 2015; Macedo-Reis et al, 2016; Corona-López et al, 2017; Novais et al, 2018b). For the Cerambycidae communities, this pattern has been recognized in the TDF of different regions of Mexico (Noguera et al, 2002; Noguera et al, 2007; Noguera et al, 2009; Noguera et al, 2012; Toledo et al, 2002).…”

“…Insect phenology has been studied in different ecosystems, including environments with little climatic seasonality such as tropical humid forests, and there are more studies in environments that present a marked differentiation between the rainy and dry periods (Wolda, 1988; Zaragoza-Caballero et al, 2010; Novais et al, 2016). The seasonal pattern of insects depends on both the taxonomic group and the environment it inhabits (Kishimoto-Yamada & Itioka, 2015).…”

Global climate change is expected to affect temperature and precipitation patterns worldwide, which in turn is likely to affect insect phenology, distribution and diversity. To improve our understanding of such processes, it is important to understand how insects may respond to changes in seasonality, and how these affect their activity, patterns of distribution and species richness. The tropical dry forest (TDF) is a highly seasonal ecosystem, for which two seasons are commonly described (rainy and dry) and there is a lack of information on the combined effect of both precipitation and temperature on the insect communities. In order to evaluate the seasonal patterns in the community of Cerambycidae in a TDF, historical climatic variables were obtained, and an annual sampling of the family was carried out, using three collection techniques. We found that the Cerambycidae family showed a more complex response to climate, than simply the rainy and dry season of the year. The relationship between diversity and composition of cerambycids with changes in temperature and precipitation showed four seasonal communities which were synchronized with phenological processes of the TDF. Climate change could reduce biodiversity, causing seasonal patterns to lose complexity, either because the climatic characteristics of a season disappear and/or because the duration of a season expands, these changes will modify the ecological processes of the TDF, since they would generate changes in the flora and fauna associated with the different seasons.

“…Las poblaciones de H. achamas y U. coarctatus presentaron una marcada estacionalidad, registrando las mayores abundancias en la época de lluvias, lo cual coincide con lo encontrado para la mayoría de los ensambles de escarabajos coprófagos que presentan cambios estacionales marcados (Peck y Forsyth, 1982;Janzen, 1983, Edwards, 1991Hanski y Cambefort, 1991;Davis, 1993;Boonrotpong et al, 2004;Novais et al, 2016) respondiendo directamente a la precipitación (Andresen, 2005) y donde la severidad de la estación seca ocasiona una fuerte disminución en la actividad de la mayoría de las especies (Hanski y Cambefort, 1991). La actividad de los escarabajos coprófagos se ve restringida a determinados picos de humedad y temperatura que condicionan su fisiología (Halffter y Montes de Oca, 1995).…”

Los escarabajos coprófagos son excelentes indicadores de la integridad ecológica de los ecosistemas, cumpliendo un rol funcional esencial en el reciclaje de nutrientes, fertilización y aireación del suelo. Sin embargo, se conoce muy poco acerca de los ensambles de escarabajos altoandinos y de su estacionalidad. Por lo anterior, se buscó entender la variación estacional de la estructura del ensamble y su efecto en la biomasa, se escogieron dos pastizales, en la Reserva Biológica Encenillo (Guasca-Cundinamarca). En cada uno se dispusieron diez trampas de caída distanciadas 50 m y cebadas con excremento durante 24 horas. Se realizaron tres réplicas en cada una de las tres épocas estudiadas (seca, transición y lluvias). Se registró una variación estacional significativa, demostrando que las especies están asociadas a la época de lluvias. Se encontraron diferencias significativas para la biomasa entre especies y por época. La especie con la mayor biomasa fue Homocopris achamas. Se evidencia que los ensambles de pastizales altoandinos son poco diversos, debido a la fuerte perturbación antrópica, las presiones asociadas con la altitud y a la misma dinámica evolutiva de estas regiones. La marcada estacionalidad de las especies registradas y la estrecha asociación con la época de lluvias concuerda con el patrón estacional que se registra en el Neotrópico. La fuerte variación estacional de la biomasa puede tener un fuerte impacto en la funcionalidad ecológica y los servicios ecosistémicos en este hábitat. Es necesario cuantificar a futuro el aporte funcional de las especies y su variación estacional, con miras a su conservación.
