Abstract Serra do Divisor National Park (SDNP) is a protected area located in the western Brazilian Amazon that threatened by pending bill proposing to downgrade its status and build road would effectively slice park half. The biodiversity of SDNP poorly understood no dung beetle inventories have been conducted within date, despite being one most studied insect groups Neotropics. We sampled beetles with flight interception traps (FITs) pitfall baited human faeces provide first comprehensive...
Thrichomys apereoides is an echimyid rodent which ranges in distribution from north‐eastern and central Brazil into Paraguay, currently five subspecies are recognized. Recent morphometric analyses of population samples formally assignable to T. a. laurentius inermis , occur Brazil, have shown that a major group populations including both differ cranial shape single allocated . In this study we employed mathematical models evolutionary quantitative genetics assess the role random drift...
Models of evolutionary quantitative genetics were employed to analyze cranial phenotypic evolution in the echimyid rodent Proechimys iheringi Thomas. The hypothesis that differentiation among populations and subspecies P. resulted from random drift was rejected. completely selective model then used reconstruct forces selection might have acted produce observed differences morphometric traits . net gradient indicates some evolved direction contrary selection, acting increase mean values for...
