“…The consequences of the invasion of D. gazella are the more worrisome, as it is now present in all states of Brazil and has been recorded in almost all countries in Central and South America, from Mexico to Uruguay (Rivera and Wolff 2007;Vidaurre et al 2008;Alvarez Bohle et al 2009;Noriega et al 2010Noriega et al , 2017. Based on our results, D. gazella is a threat to the native dung beetle fauna of all these countries and could cause serious damage to the local ecosystems.…”

Following successful establishment in Australia and North America, the South African dung beetle (DB) Digitonthophagus gazella was introduced in Brazil in 1990. We investigated the impact of the exotic species on the native community of 42 native DB species using a unique weekly data set spanning 26 years, including 4 years of pre-invasion data. The invasion of D. gazella was very rapid with abundances increasing by 4 orders of magnitude during the first few years following establishment. We show that the DB diversity shrank to sixty percent of the preinvasion level. Results from multivariate analyses identified three distinct periods of changes in composition and abundance: before the invasion (BI); after invasion I (AI-I); and AI-II each one characterized by a particular dynamic of the native species. The impacts on the native species differed according to their nesting behavior. Species with the same behavior as D. gazella (tunneler) became less abundant and five species went locally extinct. Dweller species, in contrast, became more abundant. Although the analysis of all species combined showed an increase in abundance and a less oscillatory dynamic in AI-II compared to BI, this was the case only for the dweller species, as the tunnelers showed a tendency to continued decrease throughout the 26-year study. Our results show that a new community was originated as a consequence of the invasion, in which dweller species, particularly Labarrus pseudolividus, are the dominant species and all the tunnelers, including D. gazella, are decreasing in abundance.

“…Within South America, D. gazella has been recorded due to both dispersion and unofficial introduction events in Colombia [18]- [25], Bolivia [26], Paraguay [27], Peru [28], and Argentina [29]; and only due to unofficial introduction events in Brazil [30] [31] [32], continental Chile, and Easter Island [33].…”

The invasion process involves overcoming certain barriers with negative effects on the biodiversity and ecosystem function. This is the case of the African dung beetle Digitonthophagus gazella, which was introduced in the United States and other countries in Central and South America to help in dung removal activity. The distribution of D. gazella has been documented in the Americas, but in Venezuela there is little information. Trying to understand the process of invasion of the Colombian-Venezuelan savannas and measure their potential impact, the information stored in collections and literature was collected. Five new state records were reported for Venezuela, as well as four scenarios of the process of introduction and establishment of this species in the region. Although the amount of records has increased, the number of individuals sampled is still incipient. The possible areas of invasion and the potential negative effects that the presence of this species exerts in these regions are also discussed. In addition, potential areas of invasion and negative effects of this species are discussed. Results emphasize the importance of generating models of the invasive process in order to design programs that monitor the effects incurred by the presence of D. gazella on native species and propose control and mitigation mechanisms.

“…The species has increased its distribution range, helped by anthropic introductions to other countries, colonizing Central and South America and the Caribbean (Huchet 1992, Kohlmann 1994, Gámez et al 1997, Maes et al 1997, Ruiz 2000, Noriega 2002, Noriega et al 2006, Vidaurre et al 2008.…”

ABSTRACT. Digitonthophagus gazella, a dung beetle of indoafrican origin was first introduced to the Americas in the 1970s. Since then it has increased its range through deliberate introductions by national programs and by natural spread in the absence of geographical barriers. The species continues to expand its range as it invades new regions following the anthropogenic clearing of forests. We present the first reports of D. gazella in Peru and indicate that the species is now, perhaps, the most widespread dung beetle in tropical and subtropical pastures. RESUMEN.Digitonthophagus gazella, un escarabajo coprófago de origen Indoafricano fue inicialmente introducido en el continente Americano en 1970. Desde ese momento su rango de distribución se ha incrementado debido a introducciones deliberadas en nuevas regiones y por procesos naturales de dispersión en ausencia de barreras geográficas. Esta especie ha continuado expandiendo su rango de distribución ayudado por el efecto antrópico producido por la tala de bosques. Se presenta el primer reporte de D. gazella para el Perú, indicando que esta especie se constituye en el escarabajo coprófago más ampliamente distribuido en pastizales tropicales y subtropicales.
