Assessment of Landsat-Based Evapotranspiration Using Weighing Lysimeters in the Texas High Plains

Agronomy, 2020
Evapotranspiration (ET) is one of the largest data gaps in water management due to the limited availability of measured evapotranspiration data, and because ET spatial variability is difficult to characterize at various scales.

Negative impact of freeze–thaw cycles on the survival of tardigrades

Ecological Indicators, 2023
Global warming effects in temperate and polar regions include higher average temperatures and a decrease in snow cover, which together lead to an increase in the number of freeze–thaw cycles (FTC).

Integrative taxonomy supports two new species of Macrobiotus (Tardigrada: Eutardigrada: Macrobiotidae) allowing further discussion on the genus phylogeny

European Journal of Taxonomy
In this study, I describe two new species of Macrobiotus based on morphological data collected through light and scanning electron microscopy. Both species are accompanied by DNA sequences from four commonly used molecular markers (18S rDNA, 28S rDNA ...

Using tri-axial accelerometers to identify wild polar bear behaviors

Endangered Species Research, 2017
Tri-axial accelerometers have been used to remotely identify the behaviors of a wide range of taxa. Assigning behaviors to accelerometer data often involves the use of captive animals or surrogate species, as their accelerometer signatures are generally ...
