Evidence for adaptive explanations of semelparity in animals
Biological Reviews, EarlyView.ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives
Biological Reviews, EarlyView.ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Eye Darkening Under Dehydration Stress in the Neotropical Frog Boana punctata (Schneider, 1799)
Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.Dehydration induces a strong and partially reversible increase in iris pigmentation in the Neotropical frog Boana punctata. The tight relationship between iris darkening and hydration state identifies ocular pigmentation as a simple, non‐invasive physiological biomarker with broad potential for assessing hydric stress in amphibian populations ...

Underground Lag: Fungal Community and Edaphic Legacies After Disturbance
Land Degradation &Development, EarlyView.ABSTRACT Páramos are neotropical mountain ecosystems that regulate water and store large amounts of carbon, but are increasingly degraded by agriculture and grazing. Although native vegetation often recolonizes after abandonment, belowground recovery remains poorly understood.

The Holocene, 2012 Patterns of endemism in the Neotropics have been explained by restriction of forest to ‘refugia’ in arid cold-stages of the Quaternary (Haffer J (1969) Speciation in Amazonian forest birds. Science 165: 131–137). The palaeoecological record, however, shows no such forest contraction.

Nordic Journal of Botany, EarlyView.Vitex L. is a pantropical genus of Lamiaceae comprising 209 taxa. Brazil harbors 35 species, representing nearly 50% of the genus richness in the Neotropics, with the Amazon showing the highest richness, followed by the Atlantic Forest and Cerrado domains. Nevertheless, most taxonomic studies of the genus have been conducted in Africa and Asia.

Reestablishment and a new name for Actinostemon grandifolius (Müll.Arg.) Pax
Nordic Journal of Botany, EarlyView.The genus Actinostemon has undergone several changes in its circumscription due to persistent difficulties in its taxonomic placement. The taxonomic history of the genus is controversial and marked by nomenclatural issues, particularly involving its type species, Actinostemon grandifolius Klotzsch, including incorrect synonymizations and the ...
