The nesting behavior of dung beetles (Scarabaeinae) : an ecological and evolutive approach
Biogeography of the Montane Entomofauna of Mexico and Central America
- G. Halffter
I present a synthesis of information and hypotheses that may serve as a base to explain the distribution of montane insects in the Transition Zone, a complex and varied area in which the Neotropical and the Nearctic faunas overlap.
The natural history of dung beetles of the subfamily Scarabaeinae (Coleoptera, Scarabaeidae)
Assessing the completeness of bat biodiversity inventories using species accumulation curves
This study fit two asymptotic models to species accumulation curves for bat inventories to evaluate local or within-community diversity (alpha) and landscape diversity (gamma) in central Veracruz, Mexico and proposes that 90% of the total fauna predicted by either of the models is an acceptable standardized value for comparing species richness between communities.
Frog, Bat, and Dung Beetle Diversity in the Cloud Forest and Coffee Agroecosystems of Veracruz, Mexico
Abstract: We compared the species diversity of copronecrophagous beetles (Scarabaeinae), bats, and frogs in tropical montane cloud forest (original vegetation) and shaded coffee plantations (an…
Response of Dung Beetle Diversity to Human-induced Changes in a Tropical Landscape1
Comparison of the dung beetle faunas sheds light on the relative importance of forest cover versus food supply as the principal factor determining the structure and diversity of the fauna as a case study of the effects of tropical deforestation on biodiversity.
Historical and ecological factors determining the geographical distribution of beetles (Coleoptera: Scarabaeidae: Scarabaeinae)
- G. Halffter
- Environmental Science
The relation of the Scarabs with the tropical forests of the Americas, Africa and Southeast Asia is analyzed and the structure as well as the similarities and differences of the guild on each continent are analyzed.

A decrease in the functional diversity in communities of copro-necrophagous beetles resulting from changes in land use is documented, the potential implications for ecosystem functioning are discussed and a series of variables that could improve the evaluation of functional diversity for this biological group is proposed.
The Scarabaeinae (Insecta:Coleoptera), an animal group for analyzing, inventorying and monitoring biodiversity in tropical rain forest and modified landscapes
Biogeographical and Ecological Factors Affecting the Altitudinal Variation of Mountainous Communities of Coprophagous Beetles (Coleoptera: Scarabaeoidea): a Comparative Study
The current analysis supports the hypothesis that when the horizontal colonization dominates, mountain faunas show a clear altitudinal substitution between large taxa with different evolutionary histories and the gradient of reduction in species richness is attenuated.
