Canine Leishmaniasis in Rio de Janeiro, Brazil (2000–2015): Taxonomic Characterisation of Etiological Agents and Geospatial Case Analysis

open access: yesZoonoses and Public Health, Volume 73, Issue 4, Page 314-325, June 2026.
ABSTRACT Introduction Canine Leishmaniasis is a vector‐borne zoonotic disease caused by several species of protozoa of the genus Leishmania. In the state of Rio de Janeiro (RJ), Leishmania braziliensis is the most prevalent species causing tegumentary leishmaniasis (TL) and Leishmania infantum is the main causative agent of visceral leishmaniasis (VL).

Biogeomorphic Feedbacks Triggered by Mangrove Degradation at the Seaward Margin Accelerate Persistent Vegetation Decline

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Seaward mangrove edge exhibited significant retreat after extreme disturbances. Rhizophora stylosa exhibited impaired regeneration and root damage in heavily disturbed areas, trait variation primarily responded to elevation and sediment properties, vegetation loss triggered subsidence, creating a positive biogeomorphic feedback loop.

Traits Explain Canopy Tree Occurrence Along Regional Environmental Gradients: A Subset Combine to Be Useful

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Our paper addresses the problem of “How to predict where a tree can be found from its traits?” We show that wood density, bark thickness, maximum height and seed mass combine for a useful model of tree distributions. ABSTRACT Trait‐Species Distribution Models (trait‐SDM) help to understand the importance of plant strategies to niches, assess their ...

From niche theory to demographic realities: the demographic niche concept for understanding range‐wide population dynamics

open access: yesEcography, Volume 2026, Issue 5, May 2026.
The ecological niche concept is fundamental to understanding species distributions but often overlooks the demographic processes shaping said distributions. Conversely, demographic theory has traditionally neglected how vital rates vary and covary across environments, limiting our understanding of population dynamics across species' ranges.

Direct georeferencing of multi-line images with a general sensor model

open access: yes, 2001
A general sensor model for the direct georeferencing of multi-line images acquired by CCD array sensors is under development at our Institute. The model is designed for sensors carried on both spacecraft and aircraft. If the sensor position and attitude are provided by additional observations (GPS/INS), the model computes the approximations of the ...

Geomorphic Effectiveness of an Extreme Flood in a Mountain River: Evidence From Pre‐ and Post‐Event Surveys in a Subtropical Region of Southern Brazil

open access: yesHydrological Processes, Volume 40, Issue 5, May 2026.
The extreme flooding of April 2024 caused a complete “geomorphic reset”, resulting in a 24% widening of the channel and a transition to critical or supercritical flow regimes. The energy of the event broke through the stable armouring layer, reducing the armouring ratio from 7.9 to 4.9 and intensely removing fine sediments from the subsurface.

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

open access: yesRiver Research and Applications, Volume 42, Issue 4, Page 886-900, May 2026.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Hydraulic Effects of Channel Realignment and Floodplain Reconnection in a Headwater Stream

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Channel realignment and floodplain reconnection are increasingly used as nature‐based solutions for flood management, yet their hydraulic effects remain poorly quantified in field settings of moderate‐gradient, small order channels. This study examines the impact of such interventions on hydraulic response in a headwater catchment, Goldrill ...
