“Why can't they put us to sleep if we are suffering?”: La Nada and the desire for euthanasia among institutionalized older adults in Peru

Medical Anthropology Quarterly, EarlyView.
Abstract In this article, I examine how institutionalized older adults in Peru articulate suffering through the idiom of la nada—“nothingness”—and how this shapes desires for euthanasia. Moving from close ethnography of bodies in space and time to structural and ethical discourses on euthanasia, I argue that calls for euthanasia arise not only from ...

Electrified rhythms: How hydropower infrastructure transforms hydrosocial relations of riverine communities in the Lower Sogamoso River, Colombia

People and Nature, Volume 8, Issue 3, Page 782-796, March 2026.
Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental

The Asymmetric Hydrodynamic Structure of a Wind‐Dominated River Plume

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract This study investigates the velocity and salinity structure of the large surface‐attached, low‐latitude, and microtidal plume of the Magdalena River (southern Caribbean Sea) during a period of high freshwater discharge and variable wind conditions. The plume was analyzed through observations at multiple transects along, across, and diagonal to

Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

The taxonomic status of Farlowella colombiensis Retzer & Page 1997 with comments on species of the F. acus species group (Loricariidae: Loricariinae)

Journal of Fish Biology, Volume 107, Issue 5, Page 1669-1684, November 2025.
Abstract The genus Farlowella has been historically challenging, in part due to the difficulty in defining diagnostic characters for defining and identifying the species. Farlowella colombiensis is one such example, whose diagnostic characters are based on caudal‐fin colour pattern, ventral pattern of body cover and anatomical details of the head, such

Evolutionary history of Middle American Rhamdia (Siluriformes: Heptapteridae) inferred from comparative mitogenomic data: Insights on historical biogeography and cave colonization in the group

Journal of Systematics and Evolution, Volume 63, Issue 6, Page 1501-1518, November 2025.
Investigating the systematics and biogeography of Neotropical catfishes of the genus Rhamdia refined phylogenetic hypotheses, including deep paraphyly of Rhamdia laticauda, supported northward dispersal catalyzed by emergence of the Panamanian Isthmus and imply that cave colonization is widespread, convergent, and recent, with established cave‐dwelling

Conserving Maytenus senegalensis subsp. europaea in the south‐eastern Iberian Peninsula: Integrated management strategies following 50 years of decline

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
MAYTENUS.org an initiative of interactive nexus of knowledge, meeting and debate of ideas and proposals for sustainable territorial planning in accordance with conservation goals of this species and priority habitat (see QR codes). Abstract In Mediterranean coastal landscapes under intense human pressure, conventional conservation strategies often fail

Ensuring Pollinator Presence in Expanding Oil Crops: The Case of Mystrops debilis (Nitidulidae) and the Macauba Palm (Acrocomia aculeata, Arecaceae)

Journal of Applied Entomology, Volume 149, Issue 8, Page 1180-1195, September 2025.
ABSTRACT The macauba palm (Acrocomia aculeata, Arecaceae) is a Neotropical native oil palm, increasingly important in Central and South America due to rising demand for raw materials and its potential for bioenergy. Understanding its pollinator ecology is crucial to identify new areas for cultivation. This study examines the structure of floral visitor

Persisting at the Edge of Ecological Collapse: The Impact of Urbanization on Fish and Amphibian Communities From Lake Xochimilco

Environmental DNA, Volume 7, Issue 4, July–August 2025.
ABSTRACT Freshwater ecosystems are globally threatened by habitat loss, pollution, and invasive species, all of which are particularly acute in urban areas. To assess the impacts of urbanization on freshwater biodiversity—specifically the effects of alien species on native primary aquatic vertebrates—we investigated the World Heritage Site, Lake ...
