Citizen‐Science Camera Trap Data Reveal Large‐Scale Activity Patterns of the Bobcat (Lynx rufus) Across Mexican Ecosystems

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We evaluated whether citizen science–derived camera‐trap records can be used to characterize large‐scale activity patterns of a widely distributed mesocarnivore across heterogeneous landscapes. Using 821 independent iNaturalist records, we quantified activity across six major vegetation types in Mexico with kernel density estimation, circular ...

Perfectionism and School Non‐Attendance Reasons in Adolescents: A Latent Profile Analysis

Journal of Adolescence, Volume 98, Issue 5, Page 1681-1691, July 2026.
ABSTRACT Introduction Limited prior knowledge exists regarding perfectionism and other relevant educational variables, such as the wide spectrum of School Attendance Problems. However, perfectionism has been related to somatic complaints and symptoms, school burnout, and negative emotionality. Therefore, this study analyzes the association between this

Reinstatement and generic reassignment of Phyllanthus asteranthos Croizat (Phyllanthaceae) based on living plant observations and specimen analysis

Nordic Journal of Botany, Volume 2026, Issue 7, July 2026.
Phyllanthus asteranthos Croizat has been treated as a synonym of P. pulcher Wall. ex Müll. Arg. (syn. Nymphanthus glaucescens (Miq.) R.W.Bouman) since 1987. Through detailed morphological observations of living plants and critical examinations of type materials and additional specimens, this study revealed that the two taxa are morphologically very ...

Habitat‐based spatial patterns enable realistic reconstruction of plant spatial arrangements across complex landscapes

Oikos, Volume 2026, Issue 7, July 2026.
Spatially explicit individual‐based models provide a powerful way to explore spatial dynamics when direct observation is not feasible. But for many ecological applications, these models require detailed data on the initial spatial arrangement and traits of individuals – information rarely available in large, heterogeneous or novel landscapes.

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

Boreas, Volume 55, Issue 3, Page 768-789, July 2026.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

Imaging Point Source Groundwater Discharges in a Confined Coastal Aquifer Using Electrical Resistivity

Groundwater, Volume 64, Issue 4, Page 405-421, July/August 2026.
Marine electrical resistivity tomography (ERT) is applied to characterize point‐source submarine groundwater discharge (PSGD) along NW Yucatán. ERT observations and forward modeling constrain conduit detectability under varying hydrogeological conditions.
