Amblyomma cajennense Sensu Stricto (Fabricius, 1787) and Amblyomma sculptum (Berlese, 1888) Tick Saliva Elicit Immune-Modulatory Activity in Isolated Murine Macrophages With an Insight Into Proteomic Analysis. [PDF]

Parasite Immunol
ABSTRACT Tick saliva is known to cause immunosuppression and help pathogen transmission. Amblyomma sculptum is a public health concern as a vector of Rickettsia rickettsii. Another close‐related species is Amblyomma cajennense sensu stricto (s.s.). The impact of saliva from these species on murine macrophages remains unclear.

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Demography Meets Climate Change: Life History Challenges for a Neotropical Viviparous Lizard. [PDF]

Ecol Evol
Considering the current biodiversity crisis, it is crucial to understand the impact of global environmental changes on natural populations. Analyzing demographic parameters from long‐term studies is the most effective approach to uncovering patterns that describe population dynamics.

Dispersal syndromes related to edge distance in cerrado sensu stricto fragments of central-western Brazil

Brazilian Archives of Biology and Technology, 2009
The main selective forces affecting the fruiting strategies are related to the environment in which plants occur. As a savanna, microclimatic conditions should not vary in relation to distance from edge in cerrado sensu stricto fragments.

Soil microbial C:N:P ratio across physiognomies of Brazilian Cerrado Soil microbial biomass across a gradient of preserved native Cerrado [PDF]

Anais da Academia Brasileira de Ciências, 2019
: Different physiognomies across the Cerrado could influence the microbial C:N:P ratio in the soil since these physiognomies present different abundance and diversity of plant species. Thus, the aim of this study was to evaluate the microbial C:N:P ratio
