Ecologia de triatomíneos e transmissão do Trypanosoma cruzi, com especial referência ao Brasil

open access: yesRevista da Sociedade Brasileira de Medicina Tropical, 1976
Com base em seu comportamento ecológico e seu grau de relacionamento com o homem e os mamíferos domésticos, comensais e sinantrópicos, os triatomíneos são distribuídos em seis grupos: 1) Triatomíneos tipicamente silvestres, isto é, espécies só ...

Bridging the gap in deep seafloor management: Ultra fine‐scale ecological habitat characterization of large seascapes

open access: yesRemote Sensing in Ecology and Conservation, Volume 11, Issue 4, Page 472-489, August 2025.
To achieve the UN's goal of protecting 30% of oceans by 2030, effective management and detailed seafloor mapping are essential, especially in the mesophotic zone. We present a new workflow combining high‐resolution synthetic aperture sonar (SAS) and bathymetry surveys for efficient habitat characterization. In 6 h, we mapped ~5 km2 of a mesophotic reef,

Cropping History and Cropland Abandonment Period Influenced Levels of Soil Organic Carbon, Distribution of Aggregates and Aggregate Associated Carbon

open access: yesLand Degradation &Development, Volume 36, Issue 12, Page 4183-4193, 30 July 2025.
ABSTRACT Knowledge gaps remain regarding soil organic carbon (SOC) storage and aggregate dynamics under varying cropland abandonment periods, particularly within the context of degraded and low‐SOC soils. This study aimed to assess the influence of cropping history and the period of cropland abandonment period on SOC, aggregate distribution, and ...

Life cycle of Triatoma ryckmani (Hemiptera: Reduviidae) in the laboratory, feeding patterns in nature and experimental infection with Trypanosoma cruzi

open access: yesMemorias do Instituto Oswaldo Cruz, 2010
A cohort initiated with 121 eggs, yielding 105 first instar nymphs (eclosion rate: 86.78%), allowed us to observe the entire life cycle of Triatoma ryckmani under laboratory conditions (24ºC and 62% relative humidity), by feeding them on anesthetized ...

Cancer stem cells: Bridging microenvironmental interactions and clinical therapy

open access: yesClinical and Translational Medicine, Volume 15, Issue 7, July 2025.
Cancer stem cells (CSCs) drive tumor progression through their dynamic self‐renewal capacity, epigenetic plasticity, and drug resistance. These cells interact bi‐directionally with the tumor ecosystem to promote immunosuppressive reprogramming and metastatic spread.

Understanding and predicting animal movements and distributions in the Anthropocene

open access: yesJournal of Animal Ecology, Volume 94, Issue 6, Page 1146-1164, June 2025.
This review provides a framework to better understand and predict animal movements and distributions in human‐modified environments. Bridging the gap between movement models and management/conservation policy is challenging. Here, the recommendations presented highlight the exciting opportunities now available to advance the field of movement ecology ...

Differences in bed elevation shape subtidal mussel bed stability under high‐energy hydrodynamic events

open access: yesLimnology and Oceanography, Volume 70, Issue 4, Page 1032-1045, April 2025.
Abstract Escalating high‐energy hydrodynamic events, like storms, represent a significant manifestation of global climate change, causing detrimental impacts on various ecosystems and potentially triggering thresholds that result in abrupt shifts in ecosystem states.

Hotspots in peril: Misalignment of conservation efforts and ecological values in a shallow coastal sea

open access: yesPeople and Nature, Volume 7, Issue 1, Page 160-179, January 2025.
Abstract Misalignment between the location of marine protected areas (MPAs) and ecologically valuable areas, here defined as low conservation conformity, may arise due to conflicting socioeconomic and ecological demands, diminishing MPA effectiveness.
