Source height and contact with terrestrial soil drive transplanted epiphyte performance

Journal of Ecology, Volume 111, Issue 11, Page 2388-2400, November 2023., 2023
Tropical vascular epiphytes, such as this orchid Peristeria pendula, performed worse when experimentally transplanted to new substrates in contact with terrestrial soil, versus substrates just above the soil surface. The results are some of the first empirical data supporting the epiphyte enemy escape hypothesis.

Plasticity and evolution shape the scaling of metabolism and excretion along a geothermal temperature gradient

Functional Ecology, Volume 36, Issue 5, Page 1303-1314, May 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Physiological rates are heavily dependent on temperature and body size. Most current predictions of organisms’ response to environmental warming are based on the assumption that key physiological rates such as metabolism and excretion scale independently with body size ...

Trends and knowledge gaps in field research investigating effects of anthropogenic noise

Conservation Biology, Volume 35, Issue 1, Page 115-129, February 2021., 2021
Abstract Anthropogenic noise is a globally widespread sensory pollutant, recognized as having potentially adverse effects on function, demography, and physiology in wild animals. Human population growth and associated changes in urbanization, transportation, and resource extraction all contribute to anthropogenic noise and are predicted to increase in ...

The Unstable Relationship Between Drought Status and Leaf Water Content Complicates the Remote Sensing of Tree Drought Stress. [PDF]

Glob Chang Biol
Remote sensing can monitor plant drought stress across ecosystems but is limited by uncertain links between physiological stress and measurements of water content. We examined how water potential and water content, measured in the field, laboratory, and via airborne imaging, vary over time and space in two oak species.
