Contributions of Positive Social Interactions to Vocal Learning and Social Cohesion

Ethology, EarlyView.
Birdsong produced in non‐breeding flocks is shaped by a dynamic interplay between intrinsic reward and social feedback. Studies in cowbirds and starlings suggest that positive affective states and opioid‐mediated reward promote song practice, while responses from flock mates, potentially reinforced by dopaminergic mechanisms, refine species‐typical ...

Transcriptional profiling defines dynamics of parasite tissue sequestration during malaria infection [PDF]

, 2015
During intra-erythrocytic development, late asexually replicating Plasmodium falciparum parasites sequester from peripheral circulation. This facilitates chronic infection and is linked to severe disease and organ-specific pathology including cerebral ...

When Great Powers Struggle: How Geopolitical Alignments of Small States Are Influenced by Their MNEs

Journal of Management Studies, EarlyView.
Abstract Comparing two distinct deglobalization periods, this study shows how Finnish multinational enterprises (MNEs) used corporate diplomatic activities (CDA) to influence Finland's alignment with a struggling great power. Drawing from hegemonic stability theory and new institutional economics, we argue that the power's collapsing global networks ...

Moderna visão da evolução da virulência

Revista de Saúde Pública
Atualmente considera-se que parasitas devem evoluir em direção à virulência reduzida, pois patógenos virulentos apresentam maiores probabilidades de levarem seus hospedeiros e eles próprios à extinção.

Diversity–disease relationships in natural microscopic nematode communities

Royal Society Open Science
Host diversity can affect parasite prevalence, a phenomenon widely studied in macroscopic organisms. However, data from microscopic communities are lacking, despite their essential role in ecosystem functioning and the unique experimental opportunities ...
