Biodiversity impacts of the 2019-2020 Australian megafires.

With large wildfires becoming more frequent, we must rapidly learn how megafires impact biodiversity to prioritize mitigation and improve policy. A key challenge is to discover how interactions among fire-regime components, drought and land tenure shape wildfire impacts. The globally unprecedented 2019-2020 Australian megafires burnt more than 10 million hectares, prompting major investment in biodiversity monitoring.

Attractant Activity of Host-Related Chemical Blends on the Poultry Red Mite at Different Spatial Scales.

Many blood-feeding arthropods use volatile organic compounds (VOCs) to detect their vertebrate hosts. The role of chemical interactions in mediating the behavior of hematophagous insects and ticks has been investigated before but remains poorly understood in hematophagous mesostigmatic mites. The poultry red mite Dermanyssus gallinae is an obligatory blood-sucking mesostigmatic mite that feeds on birds and causes damage in poultry farms.

Cephalocyclus iohannisgabrielis (Coleoptera: Scarabaeidae: Aphodiinae), a new species from Oaxaca, Mexico.

The genus Cephalocyclus Dellacasa, Gordon Dellacasa, 1998 (Coleoptera: Scarabaeidae: Aphodiinae: Aphodiini) was created for 10 species distributed in southern United States of America and Mesoamerica. Subsequently, 14 species were described or added to this genus (Dellacasa et al. 2000, 2007, 2011, 2013; Deloya Ibáñez-Bernal 2000; Minor et al.

Modulation of feed composition is able to make hens less attractive to the poultry red mite .

The poultry red mite (PRM) is an obligatory haematophagous pest that causes substantial economic losses in poultry worldwide. The PRM does not live on the host but in the bird's environment and must find its host remotely. Hence, manipulating chicken odours is of interest.

Gonaphodioides zempoaltepetlensis (Coleoptera: Scarabaeidae: Aphodiinae), a new species from Oaxaca, Mexico.

The genus Gonaphodioides Dellacasa, Dellacasa, Gordon, 2012 (Coleoptera: Scarabaeidae: Aphodiinae: Aphodiini) was created for seven species distributed in Mesoamerica and South America. Subsequently, G. cartwrighti Dellacasa, Dellacasa, Gordon, 2013 was described from El Salvador (Dellacasa et al.

An unusual new species of Canthidium (Coleoptera: Scarabaeidae: Scarabaeinae) from Oaxaca, Mexico.

In this paper we describe Canthidium quercetorum new species (Coleoptera: Scarabaeidae: Scarabaeinae), a species that inhabits dry oak forest in the Mexican state of Oaxaca, between 2100 and 2300 m above sea level. Photographs and an illustration of the habitus and a distribution map are provided. The unusual distribution and ecology of this species are discussed.

Dung beetle vicariant speciation in the mountains of Oaxaca, Mexico, with a description of a new species of (Coleoptera, Geotrupidae, Scarabaeidae).

An analysis of vicariant speciation of and (Coleoptera, Geotrupidae, Scarabaeidae) from the mountains of Oaxaca, Mexico is undertaken. The new species of dung beetle (Coleoptera: Scarabaeidae) from Oaxaca, Mexico, is described. Photos of the habitus and a distribution map are provided.

High variability of dung beetle diversity patterns at four mountains of the Trans-Mexican Volcanic Belt.

Insect diversity patterns of high mountain ecosystems remain poorly studied in the tropics. Sampling dung beetles of the subfamilies Aphodiinae, Scarabaeinae, and Geotrupinae was carried out at four volcanoes in the Trans-Mexican Volcanic Belt (TMVB) in the Mexican transition zone at 2,700 and 3,400 MASL, and on the windward and leeward sides. Sampling units represented a forest-shrubland-pasture (FSP) mosaic typical of this mountain region.

Co1 DNA supports conspecificity of Geomyphiluspierai and G.barrerai (Coleoptera, Scarabaeidae, Aphodiinae) and is a good marker for their phylogeographic investigation in Mexican mountains.

Members of Geomyphilus are associated with rodent burrows, such as pocket gophers and prairie dogs. In Mexico, they are found in the mountains of the Mexican Volcanic Belt and in Sierra Madre Oriental. Our study aims to initiate the exploration of the dispersal modes of Geomyphiluspierai and Geomyphilusbarrerai from burrows of pocket gophers.
