“…To understand the impact of livestock activities on dung beetle diversity over the last 20 years, analyses are increasingly investigating livestock practices and management. Some past studies have assessed the effects of shaded fields (Horgan, 2002(Horgan, , 2005, site complexity, soil quality, and management (de Farias et al, 2015); ivermectin use (Flota-Bañuelos et al, 2012;Tovar et al, 2016), fire use (Rangel-Acosta et al, 2020); cattle grazing abandonment time (Correa et al, 2019a(Correa et al, , 2020b, animal consortium (e.g., horse and cattle, Louzada and Carvalho e Silva, 2009;sheep and cattle;Correa et al, 2020c), rotational pasture management (Correa et al, 2021a) and livestock intensification (Alvarado et al, 2018).…”

Dung beetles are one of the most representative groups of insects associated with livestock, as they take advantage of the manure of livestock for food and reproduction. They have been widely used as a bio-indicator group to evaluate their responses to land-use change and other environmental disturbances by analyzing species diversity at different spatial and temporal scales. However, the impacts of livestock management practices, forms, and history on dung beetle diversity are still poorly understood. This paper is an exhaustive and systematic review of the existing peer-reviewed and indexed literature on the taxonomic diversity (species richness and composition), functional diversity, and ecological functions of dung beetles from different provinces and biogeographic domains in tropical grazing lands of the Neotropics. We analyzed the timeline of the studies conducted so far, and we detected increasing literature produced mainly in South America. We included the most frequent objectives, tendencies, software, and statistical analyses. Given the significant heterogeneity of livestock landscapes in the Neotropics, the reviewed studies have conceptualized broadly what a pasture is, and the authors have used different descriptions of other grazing lands. Additionally, management data and livestock practices vary widely among studies, and management history is poorly described. In future research, it is relevant to include as much information as possible and the consequences of different livestock management practices on additional ecological attributes of dung beetle assemblages at different landscape scales (spatial and temporal) to predict how ecological processes change in Neotropical landscapes. Considering the importance of the data to be included in future work, we propose a collection format to unify the information collected in the field when conducting ecological studies in grazing lands. Moreover, we define a classification system to homogenize the features that distinguish the multiple tropical grazing lands reported in the literature. Preserving dung beetle diversity and associated ecological functions is urgent for maintaining ecosystem services in grazing lands. The challenge for research institutions is to continue filling gaps in knowledge to help those who work in transferring knowledge, to help ranchers exercise better options for more sustainable livestock farming, and to publish results for conservation decision-making.

“…La cobertura del muestreo tanto a las 24 h como a las 48 h de operación de las trampas de este estudio fue cercana al 100 %. Sin embargo, este valor no difiere a lo reportado en estudios previos realizados en fragmentos de bosque seco en el Caribe colombiano, donde la cobertura del muestreo se encuentra entre el 90-100 %, con solo 24 h de operación de la trampa de caída (Barraza et al, 2010;Navarro et al, 2011;Rangel-Acosta et al, 2016a;Rangel-Acosta et al, 2016b;Rangel-Acosta et al, 2018;Rangel-Acosta et al, 2020;Solís et al, 2011). Lo anterior deja en evidencia que 24 h de operación de las trampas de caída es suficiente para obtener una buena estimación de la riqueza, abundancia y biomasa de escarabajos coprófagos en BST del Caribe colombiano.…”

Introducción: Tradicionalmente, los estudios de escarabajos coprófagos en los bosques secos tropicales (BST) del Caribe colombiano han aplicado metodologías diseñadas para zonas húmedas y andinas del país, lo cual podría estar incidiendo en el rendimiento y la eficiencia del muestreo. Objetivo: Con el fin de aportar a esta discusión, se analizó cómo la cantidad de cebo y el tiempo de operación de la trampa de caída inciden en la efectividad de captura de escarabajos coprófagos en un fragmento de BST en La Reserva Campesina la Flecha, San Jacinto, Colombia. Métodos: Para la captura de los escarabajos, se utilizó trampas de caída, cebadas con tres cantidades diferentes de atrayente: pequeño (34.6 g), mediano (53.8 g) y grande (114.9 g), las cuales permanecieron activas en campo durante 48 h. Cuatro muestreos fueron realizados entre marzo y septiembre de 2015, abarcando por igual la época seca y de lluvia. Resultados: Se registró un total de 4 563 individuos, agrupados en 10 géneros y 27 especies de escarabajos coprófagos. Los mayores valores de riqueza, abundancia y biomasa se presentaron en el cebo grande, a las 48 h, durante la época de lluvias. Sin embargo, el tiempo de operación de la trampa no tuvo efecto en la estimación de la riqueza, abundancia y biomasa de escarabajos independientemente de los tamaños de cebo. Los tres órdenes de la diversidad (0D, 1D y 2D), presentaron valores similares entre las cantidades de cebo durante la época de lluvia, pero en la época seca, los cebos de mayor tamaño presentaron los valores de diversidad más altos. Por su parte con el cebo de mayor tamaño se capturó significativamente más riqueza, abundancia y biomasa de escarabajos de cuerpo pequeño y grande siendo esta situación más notaria durante la época seca. Conclusiones: Los resultados de este trabajo evidencian que para el estudio de los ensamblajes de escarabajos en el BST la utilización de un cebo de mayor tamaño contribuye a una mejor estimación de riqueza, abundancia, diversidad y biomasa, sobre todo durante la época seca, cuando las condiciones ambientales propician que los cebos pierdan su atractividad con mayor rapidez.

“…In Colombia, most studies have focused on diversity (Otavo et al, 2013;Martínez and Lopera-Toro, 2014;Martínez et al, 2018;Amell-Caez et al, 2019), evaluate the response to disturbances (Rangel-Acosta et al, 2020), list of species for the country (Medina et al, 2001) and studies on their diet (Bustos-Gómez and Lopera-Toro, 2003;Noriega, 2012), but none have focused on issues relevant to the sexual ratio. Fishers (1930) postulated that the sex ratio of most species tends to be one-toone; however, some species have been observed to deviate from this ratio, in order to maximize the evolutionary potential and long-term prospects of a population (Tabadkani et al, 2012;Wedekind, 2012).…”

Objective: Our study aimed to test whether the populations of dung beetle maintain the Fisherian sexes ratio a primary forest of an Andean-Amazonian ecosystems. Scope. Promote knowledge of the diversity of Scarabaeidae: Scarabaeinae from Caquetá, Colombia. Methodology: Coprophagous beetles were collected using 50 Pitfall traps baited with human feces separated from each other by 10 meters. Each trap was active for 72 continuous hours. Species were classified according to the trophic guilds and three size categories. Sampling effort was explored using an accumulation curve, meanwhile, Hill numbers were calculated to measure diversity. the Fisher test was performed to analyze the sexual ratio. A Chi-Square (X2) goodness test was performed to analyze if there were significant differences between trophic guild, species, sex and sizes. Results: In total, 693 individuals were collected, distributed in 12 genera and 26 species. The most abundant species were Eurysternus cayennensis Castelnau, 1840 and Dichotomius ( ichotomius) quinquelobatus (Felsche, 1910). The dominant trophic guilds were Diggers. The accumulation curve showed that the sampling effort were satisfactory, meanwhile, the Hill index showed that the abundances between species are heterogeneous. Fisher’s test showed a sexual ratio of 1.4:1 male-female. The X2 test showed that there were significant differences between the trophic guild, species, sex and sizes. This study is the first approximation of the sexual ratio of dung beetles in the Colombian Andean-Amazonian region. Conclusions: This study provides relevant information on the sex ratio and habits occurrence for 12 genera and 26 species of Scarabaeidae that occur in the Parque Nacional Natural Alto Fragua Indi Wasi, San José del Fragua, Caquetá, Colombia.
