Land tenure contributions to protected area growth under alternative conservation targets in the Australian monsoon tropics. [PDF]
Conserv BiolAbstract As the global protected area (PA) network expands to meet international targets, it is important to assess whether traditional reliance on public land will suffice for projected PA growth or whether other tenures, such as Indigenous or pastoral lands, may increasingly contribute.

Interdependencies between Indigenous peoples, local communities, and freshwater systems in a changing Amazon. [PDF]
Conserv BiolAbstract Globally, Indigenous peoples and local communities (IPs and LCs) are fighting for the recognition of their knowledge and decision‐making authority in freshwater conservation. In the Amazon, decision‐making around freshwater management and conservation has often overlooked Indigenous and local knowledge (ILK) and the connections between ...

Conservation Biology, Volume 36, Issue 6, December 2022., 2022 Abstract Africa's protected areas (PAs) are the last stronghold of the continent's unique biodiversity, but they appear increasingly threatened by climate change, substantial human population growth, and land‐use change. Conservation planning is challenged by uncertainty about how strongly and where these drivers will interact over the next few decades.

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Nanocomposite permanent magnets with reduced rare‐earth content represent a promising class of materials for next‐generation high‐performance applications. However, asynchronous precipitation of soft and hard magnetic phases often results in grain size mismatch and limited coercivity.

Novel Non‐Equimolar High‐Entropy Zirconates With Superior Thermophysical Properties
Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Rare‐earth zirconates (RE2Zr2O7) are promising candidates for topcoat materials in thermal barrier coatings (TBCs). However, their practical application in TBCs is limited by poor fracture toughness and low thermal expansion coefficient (TEC).

Optimized Copper Distribution and Enhanced Coercivity in PrO2‐Doped Sm2Co17‐Type Magnets
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT A rational design of Cu distribution is crucial for achieving optimal magnetic properties in Sm2Co17‐type magnets. In this study, nanostructured PrO2 powders were employed to induce Cu redistribution at grain boundaries while preserving the cellular microstructure. The corresponding coercivity (Hcj), remanence (Br), and maximum energy product (
