Environmental and Evolutionary Forces Shaping Penguin Geographic Limits

open access: yesJournal of Biogeography, Volume 52, Issue 9, September 2025.
ABSTRACT Aim Penguins are seabirds exclusively found in the Southern Hemisphere, with their existence dating back to the late Cretaceous. Despite their exceptional dispersal capabilities, which allow them to inhabit a wide range of environments—from polar regions to temperate zones, and even near the Equator—penguins are absent in the Northern ...

SENSORIAMENTO REMOTO ORBITAL PARA MODELAGEM DA EVAPOTRANSPIRAÇÃO: SÍNTESE TEÓRICA E APLICAÇÕES EM COMPUTAÇÃO NA NUVEM

open access: yes, 2021
The objective of this review article was compiling the theoretical and technological aspects of remote sensing-based evapotranspiration (ET) modeling. We surveyed the thermohydrological concepts that support the ET phenomenon, such as soil energy fluxes (

The Influence of Land Surface Temperature in Evapotranspiration Estimated by the S-SEBI Model

open access: yesAtmosphere, 2020
Evapotranspiration (ET) is one of the least understood components of the hydrological cycle. Its applications are varied, from agricultural, ecological and hydrological monitoring, to control of the evolution of climate change.

Phylogenetic conservatism in the relationship between functional and demographic characteristics in Amazon tree taxa

open access: yesFunctional Ecology, Volume 39, Issue 1, Page 181-198, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Leaf and wood functional traits of trees are related to growth, reproduction, and survival, but the degree of phylogenetic conservatism in these relationships is largely unknown.

Evapotranspiration Estimation with the S-SEBI Method from Landsat 8 Data against Lysimeter Measurements at the Barrax Site, Spain

open access: yesRemote Sensing, 2021
Evapotranspiration (ET) is a variable of the climatic system and hydrological cycle that plays an important role in biosphere–atmosphere–hydrosphere interactions. In this paper, remote sensing-based ET estimates with the simplified surface energy balance

Towards a global understanding of tree mortality [PDF]

open access: yesnew phytologist
Summary Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground‐based long‐term forest monitoring with large‐scale remote sensing.
