Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate. [PDF]

New Phytol
Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

Jaguar Density at the Northeastern Limit of Its Distribution in Mexico. [PDF]

Ecol Evol
This study presents the first estimate of jaguar density in northeastern Mexico using a spatial capture–recapture model with random thinning, which incorporates both identified and unidentified camera trap detections. Conducted over 91 days with 104 cameras, the model yielded a density of 1.29 individuals per 100 km2 in the El Cielo–Sierra de Tamalave ...

Leaf Length Predicts Twig Xylem Vessel Diameter Across Angiosperms. [PDF]

Plant Cell Environ
ABSTRACT As plants grow taller, increasing conductive pathlength imposes hydraulic resistance, challenging the maintenance of water transport to leaves. While tip‐to‐base conduit widening along the stem helps mitigate this resistance, theoretical models and empirical data suggest that stem widening alone is insufficient to fully compensate.

Comparative Community Ecology Reveals Conserved Ectoparasite Microbiomes Amidst Variable Host and Environment Microbiomes. [PDF]

Ecol Evol
Our results indicate that ectoparasite microbiomes are highly conserved and specific. In contrast, we found high geographic variation in host and environmental microbiomes, suggesting that there may be a constraint on blood‐feeding insect ectoparasites to maintain a specific microbiome.

Beyond ‘desirable’ values: Expanding relational values research to reflect the diversity of human–nature relationships

People and Nature, Volume 5, Issue 6, Page 1774-1785, December 2023., 2023
Abstract In recent years, environmental values have become increasingly important for understanding human–environment relationships and transitions towards sustainability. Pluralistic valuation seeks to account for values associated with the diversity of human–nature relationships.
