Urban expansion and wetland shrinkage estimation using QGIS- tool: A Kolkata Case-Study [PDF]

EPJ Web of Conferences
Urban wetlands are important natural reservoirs that help to regulate water cycles, weather and the environment at large in rapidly growing cities. Unfortunately, the fast pace of urban growth has led to the loss of many of these natural habitats.

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin

Oikos, EarlyView.
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.

Shifting the paradigm: An Indigenous knowledge‐based stewardship plan to replenish boreal caribou in Athabasca Chipewyan and Mikisew Cree First Nations' homelands

People and Nature, EarlyView.
Abstract Indigenous Peoples in northern Alberta, including Dené and Cree of the Athabasca Chipewyan and Mikisew Cree First Nations (ACFN and MCFN), have been using Indigenous laws and stewardship principles to care for their homelands for thousands of years. Since ACFN and MCFN signed Treaty 8 with Canada in 1899, Alberta's land management policies and

Spatial Variability of Permafrost and Active Layer Thickness in a Forested Hillslope of the Taiga Shield

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

A comprehensive checklist of Mediterranean wild edible plants: Diversity, traditional uses, and knowledge gaps

PLANTS, PEOPLE, PLANET, EarlyView.
The use of wild edible plants and the traditional knowledge associated with them are rapidly disappearing across the Mediterranean, with serious consequences for biodiversity, cultural heritage, and regional food security. This study compiles and organizes fragmented information to create the first comprehensive catalogue of these plants across the ...

Climate requirements for cultivated Liberica coffee (Coffea liberica) and consequences for its use and development as a crop species

PLANTS, PEOPLE, PLANET, EarlyView.
The global coffee industry, supporting 25 million smallholder farmers, is vulnerable to climate change. Diversifying the coffee species portfolio beyond Arabica and robusta is a promising intervention. Liberica coffee could provide adaptive capacity, although its climate parameters for cultivation are poorly known.

Rethinking intensification: Biodiversity‐inclusive management sustains coconut yields

PLANTS, PEOPLE, PLANET, EarlyView.
Coconut palm expansion in West Africa will shape rural livelihoods and ecosystems. Our findings show that intensive practices reduce beneficial soil fungi and increase pathogens, threatening long‐term productivity. Lower‐intensity management that retains ground vegetation can sustain or boost yields while improving soil health.
