Addressing multiple management goals during roadside restoration: reducing weed invasion and fire risk while enhancing native plants and pollinator habitat in semiarid, invaded grasslands

Restoration Ecology, EarlyView.
Abstract Introduction Roadside vegetation management efforts often target a single desirable outcome; however, we frequently have multiple management goals for restoration. Multiple goals may be achieved concurrently, but the efficacy of roadside revegetation methods is largely unclear, especially when multiple methods are combined.

Spatial and temporal scales in plant phenotyping for crop water stress assessment: A review

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Water stress is a major limiting factor for crop productivity worldwide, and its impacts are intensifying due to climate variability and increasing water scarcity. This review focuses on the spatial and temporal scales in plant phenotyping as a critical approach to improving crop water‐stress assessment and supporting precision water ...

Comparative study of SPI and SPEI drought indices for meteorological drought assessment in Mauritius

Jàmbá
Drought is a global issue affecting many countries, including Mauritius, which is vulnerable to this natural hazard. This study compares two robust drought indices: the Standardised Precipitation Index (SPI) and its variant the Standardised Precipitation

Proximate Climate Drivers of Beaver Pond Occupancy and Range Expansion in Arctic Alaska

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
To understand why beavers are colonizing the Arctic, we evaluated which climate drivers underpin beaver pond dynamics. Warm Junes, mild winters, green summers, and wet springs facilitate pond establishment. Rapid improvement in these conditions across recent decades provides mechanistic support that climate change is driving beaver colonization of the ...

Hydrological regime change and water scarcity in a semi-arid lacustrine ecosystem: A case study of lake Abkhan (Middle Atlas Mountains of Morocco) using remote sensing and drought indices [PDF]

E3S Web of Conferences
This study examines the determinants of hydrological degradation of Lake Abkhan, an endorheic wetland in the Middle Atlas Mountains of Morocco, over four decades (1984-2024). The methodological approach combines the analysis of drought indices (SPI, SPEI)

Molecular phylogenetics of Thymelaeaceae‐Thymelaeoideae: Resolving the paraphyly of Gnidia and a new monophyletic generic classification for the group

TAXON, Volume 75, Issue 4, August 2026.
Abstract Earlier phylogenetic analyses of the family Thymelaeaceae using combined plastid (matK, rbcL, rps16, trnL‐F) and nuclear (ITS) regions showed that the African‐Malagasy genus Gnidia was extensively polyphyletic in relation to the southern African genera Lachnaea, Passerina and Struthiola, as well as to other Southern Hemisphere genera such as ...

Using SPEI for Evaluating of Global Warming Effects on Drought [PDF]

, 2013
Severity of the drought will significantly increase with increasing temperature. The earth’s surface weather temperature was increased due to global warming and a 3-5 °C temperature increase are projected in the next 100 years.
