Sexual selection and reproductive success in mesocosm populations of African annual killifish

Journal of Fish Biology, EarlyView.
Abstract Variation in individuals’ ability to obtain mates generates sexual selection, which typically acts more strongly on males and can produce pronounced differences in phenotypes between the sexes (i.e., sexual dimorphism). The dynamic of sexual selection and individual reproductive success is considerably affected by the availability of ...

Virtual brain endocasts of the palaeanodont Metacheiromys marshi and the neurosensory evolution of early Pholidotamorpha

Journal of Anatomy, EarlyView.
We describe the endocranial anatomy of Metacheiromys marshi. Decrease in olfaction and eye movement control occurred through time in Pholidotamorpha and is likely linked to fossorial adaptations. The development of the orbital gyrus might be related to the evolution of myrmecophagy and the emergence of a protrusile tongue in early Pholidotamorpha ...

The Landless Rural Workers Movement (MST) and New Agrarian Questions in Brazil

Journal of Agrarian Change, EarlyView.
ABSTRACT The Landless Rural Workers Movement of Brazil (MST) primarily organized occupations of large‐scale farms, forcing the redistribution of land for creation of agrarian reform settlements. In the past 20 years, however, land occupations and the establishment of new agrarian reform settlements have consistently declined, while the MST shifted ...

Occurrence and distribution of sarcoptic mange in wild Neotropical canids

Medical and Veterinary Entomology, EarlyView.
Sarcoptic mange affects most Neotropical canid species across multiple countries. It represents a widespread yet largely overlooked conservation threat with potential for cross‐species transmission. Coordinated monitoring and management efforts are needed to understand and mitigate its impacts. Abstract Sarcoptic mange, a contagious skin disease caused

Fine‐root trait variation in temperate trees follows arc‐shape pattern along deep soil profiles

New Phytologist, EarlyView.
Root trait variation along the soil depth profile in four temperate tree species. Summary Roots are plants' interface with the soil, controlling access to water and nutrients. Yet, fine‐root trait variation along deep soil profiles and its functional implications remain poorly understood.
