Rickettsiales in South America: A Systematic Review of Their Molecular Detection and Distribution in Arthropods and Vertebrates

Public Health Challenges, Volume 5, Issue 2, June 2026.
ABSTRACT Bacteria of the order Rickettsiales comprise a diverse group of obligate intracellular microorganisms that are globally distributed and highly prevalent in tropical and subtropical regions. In South America, these bacteria have been associated with arthropod vectors, such as ticks, fleas, mites, lice, and certain dipterans, as well as with a ...

Must the Shit Hit the Fan Before Anyone Responds? Response‐Activating Texts as Catalysts for Organisational Responsiveness

Risk, Hazards &Crisis in Public Policy, Volume 17, Issue 2, June 2026.
ABSTRACT The article examines how ‘soft’ information functions in rational organisations that emphasise hard information, and how this affects safety. Drawing on fieldwork in a high‐security prison, we analyse how frontline personnel interpret soft information about potential disturbances. We identify three coexisting institutional logics shaping these

A distributed large‐volume soil sampling approach to address spatial heterogeneity in eDNA data collection

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1726-1734, June 2026.
Abstract Soil sampling for eDNA is a useful approach to assess ecological communities in specific locations, such as comparing community composition across different site treatments. However, species' dispersal abilities and habitat selection, among many other factors, drive the uneven distribution of organisms across the landscape. Thus, to accurately

Spatial Ecology and Habitat Selection by Jaguars and Pumas in a Protected Area in the Atlantic Forest of Brazil

Austral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Understanding animal distribution is crucial for elucidating natural history, population dynamics, and inter‐ and intraspecific interactions. This knowledge informs the planning and evaluation of management and conservation strategies, particularly for sympatric, scarce, and threatened species such as jaguars (Panthera onca) and pumas (Puma ...

Scenarios and strategies for future‐proofing ecosystem management under climatic novelty

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Climate change is driving unprecedented declines in dominant, habitat‐forming foundation species across marine and terrestrial ecosystems globally. As climatic novelty becomes the norm, ecosystem reassembly will become increasingly common. Predicting and understanding these transitions, and their implications for future ecosystem functioning ...
