Plant Responses to Anomalous Heat and Drought Events in the Sonoran Desert. [PDF]

open access: yesGlob Chang Biol
What are the impacts of region‐wide heat and drought events on desert vegetation? This multi‐scale assessment shows that columnar cacti and succulent trees show acute plant stress across the Sonoran Desert. The expected increased frequency of heat and drought events will likely have landscape‐wide impacts that could fundamentally reshape populations of

Global maps of soil temperature. [PDF]

open access: yesGlob Chang Biol, 2022
We provide global maps of soil temperature at a 1 km2 resolution, based on a global database of more than 8500 in situ soil temperature time series. We show that over the year, soils in cold and/or dry biomes are on average 3.6°C warmer, whereas soils in warm and humid environments are 0.7°C cooler than gridded air temperature.

Image analysis to estimate mulch residue in soil. [PDF]

open access: yesScientificWorldJournal, 2014
Mulching is used to improve the condition of agricultural soils by covering the soil with different materials, mainly black polyethylene (PE). However, problems derived from its use are how to remove it from the field and, in the case of it remaining in the soil, the possible effects on it.

Palynological evidence of Middle Pleistocene palaeoenvironmental changes from the ‘Buca dell’Onice’ flowstone (Alpi Apuane, Central Italy)

open access: yesThe Depositional Record, Volume 8, Issue 1, Page 340-354, February 2022., 2022
An exceptionally thick Middle Pleistocene flowstone is preserved in the Alpi Apuane (central Italy). Two main depositional cycles, separated by a physical discontinuity, have been characterised by sedimentological and pilot palynological studies which suggest that deposition occured during humid phases under both warm and cool climate conditions ...

Geospatial Analysis of Soil Erosion including Precipitation Scenarios in a Conservation Area of the Amazon Region in Peru

open access: yesApplied and Environmental Soil Science, Volume 2021, Issue 1, 2021., 2021
The Tilacancha Private Conservation Area provides fresh water to the city of Chachapoyas. Therefore, the amount of soil lost in the year and under precipitation scenarios was determined. Individually, the values of the factors were obtained: rain erosivity (R) in 2019 and simulating increase and decrease of 15% of rainfall, soil erodibility (K), length

Flood related mortality in a touristic island: Mallorca (Balearic Islands) 1960–2018

open access: yesJournal of Flood Risk Management, Volume 13, Issue 4, December 2020., 2020
Abstract Although they exist, fatalities related to floods are a rare occurrence in the island of Mallorca. In the aftermath of the Sant Llorenç flash‐flood of October 2018, which killed 13 people, a research was undertaken to develop database gathering information about the flood related victims on the island.

Cold Recycled Asphalt Mixture using 100% RAP with Emulsified Asphalt‐Recycling Agent as a New Pavement Base Course

open access: yesAdvances in Materials Science and Engineering, Volume 2020, Issue 1, 2020., 2020
The rehabilitation process of asphalt pavements using the technique of milling and filling can cause several environmental problems due to either the disposal of the milled asphalt mix or the exploration of natural resources. One alternative to mitigate these impacts is to reuse this milled material, known as reclaimed asphalt pavement (RAP), in the ...

Droughts in central Chile using different indices during the 1981-2010 period

open access: yesInvestigaciones Geográficas, 2015
The different dimensions of meteorological drought in central Chile in order to characterize their occurrence at multiple time scales and find evidence of variability and change in frequency are analyzed. For that, there are 27 meteorological stations at

Diurnal Variation of Rainfall in a Tropical Coastal Region with Complex Orography

open access: yesAtmosphere, 2019
We examined the diurnal cycle of the rainfall in a coastal tropical mountainous region in central Veracruz State, Mexico (18°−21° N, 95.5°−98.5° W), featuring a striking topographic gradient running from sea level at the ...
