Integrating LiDAR, Multispectral and SAR Data to Estimate and Map Canopy Height in Tropical Forests

open access: yesRemote Sensing, 2019
Developing accurate methods to map vegetation structure in tropical forests is essential to protect their biodiversity and improve their carbon stock estimation. We integrated LIDAR (Light Detection and Ranging), multispectral and SAR (Synthetic Aperture

Climate change and fire alter biotic interactions and tree growth in high‐elevation forests

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract Climate change and shifting fire regimes have the potential to alter forest structure and tree growth dynamics in high‐elevation forests; however, the relative role of competitive and facilitative interactions in shaping postfire responses remains unclear.

Signal Amplification in the HPT Axis—Evidence for Its Existence, Location, Significance, and Molecular Mechanisms

open access: yesActa Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Thyroid hormones (THs) are under negative feedback regulation via the hypothalamic–pituitary‐thyroid (HPT) axis. How this axis operates to keep the circulating THs within a narrow physiological range is not well understood quantitatively. Led by the design principle of robust homeostatic feedback control, here we review and synthesize the ...

Sourcing carnelian beads from the ancient Mesopotamian site of Kish, Iraq, 2450–2200 BCE: Stylistic, technological and geochemical approaches

open access: yesArchaeometry, Volume 68, Issue S1, Page S22-S37, April 2026.
Abstract Trade between Mesopotamia and the Indus Civilization is studied through the analysis of Early Dynastic III Period (2600–2350 BCE) carnelian beads from the site of Kish, Iraq. Morphological and technological features of the beads are compared with beads from the Indus region.

GeoNav: Enhancing field phenotyping with high‐precision global navigation systems integration in the Field Book mobile application

open access: yesCrop Science, Volume 66, Issue 2, March/April 2026.
Abstract Field data collection is a key activity in plant breeding, underpinning efforts to develop crop varieties with improved yields, disease resistance, and climate adaptability. Accurately associating data with the correct field plots is critical for selection and genetic improvement but can be challenging, especially in large experiments.

Water Oxygen Isotope Thermometer in Headwaters: Indicating Groundwater Recharge and Peatland Water Dependence on Air Temperature

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
Stable isotopes in water act as natural tracers of precipitation temperature. In mountainous environments, the oxygen isotopic signature measured in stream water reflects air temperature during precipitation events. Oxygen‐isotope‐derived temperatures are closely linked to recharge processes, particularly in peatlands, as well as in groundwater systems.

Tibial periosteal ganglion cyst: The ganglion in disguise

open access: yesIndian Journal of Radiology and Imaging, 2017
Soft tissue ganglions are commonly encountered cystic lesions around the wrist presumed to arise from myxomatous degeneration of periarticular connective tissue. Lesions with similar pathology in subchondral location close to joints, and often simulating

Relative pollen productivity estimates from India: A step towards quantitative reconstruction of past plant abundance

open access: yesEcosphere, Volume 17, Issue 2, February 2026.
Abstract Pollen records and models of pollen–vegetation relationships are required to reconstruct past plant abundances during the Holocene to answer specific questions on climate history, human impact, biodiversity, and their interactions. An important parameter for model applications is pollen productivity, estimated as relative pollen productivity ...
