Effect of Habitat Height on Artemisinin Production and the Existence of Chemotype in Artemisia Species

open access: yesWorld Journal of Traditional Chinese Medicine
Objective: The study aimed to explore novel artemisinin plant sources as an alternative to Artemisia annua, to study the effect of habitat height on artemisinin concentration, and to find out the existence of chemotypes in Artemisia species.

Climate‐Driven Habitat Suitability Modeling for the Vulnerable Species Euryops pinifolius A. Rich in Ethiopia: Implications for Conservation

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Euryops pinifolius, vulnerable plant species in Ethiopia's Afroalpine ecosystem, faces serious threats from overexploitation for fuelwood. Using the MaxEnt model (AUC = 0.985), this study identified key environmental factors‐such as temperature, altitude, vegetation cover, and precipitation seasonality‐affecting its current and future habitat ...

Comparative Chloroplast Genomics of Cousinia (Asteraceae) With Nine Newly Sequenced Endemic Species From Central Asia

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
In this study, nine complete chloroplast genomes of Cousinia species endemic to the Pamir–Alay mountain system were sequenced and analyzed together with previously published plastomes and nuclear ribosomal ITS data. ABSTRACT Cousinia (Asteraceae: Cardueae) represents one of the most species‐rich genera within the Irano–Turanian floristic region, yet ...

Natural Products as the Modulators of Gut Microbiota: A Pool for the Development of New Treatment Against Obesity?

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Natural compounds regulate gut microbiota by improving microbial balance and increasing probiotics, which boost short‐chain fatty acid production to alleviate insulin resistance and inflammation. Additionally, they stimulate appetite‐suppressing hormones through bile acid signaling, while inhibiting pathogenic bacteria to repair intestinal barrier ...

Investigation on Flow Resistance of Large‐Scale Channels With Unmanaged Spontaneous Vegetation

open access: yesHydrological Processes, Volume 40, Issue 5, May 2026.
The hydraulic measurements of two surveys (November 1995 and June 1996) by Flippin‐Dudley et al. were used. A theoretical flow resistance equation was assessed for a large‐scale vegetated channel. The analysis demonstrated that the theoretical flow resistance equation allows an accurate estimate of the Darcy–Weisbach friction factor.

Moose indifferent to canopy loss from forest disturbance by bark beetles

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
Moose showed strikingly similar patterns of habitat selection before and after widespread forest disturbance following an infestation of bark beetles. Our findings indicate that beetle‐kill does not appreciably alter habitat quality for moose and highlight the importance of riparian areas in sustaining moose as they contend with changing forests ...

Supporting interventions to lessen human–wildlife conflict

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1100-1116, May 2026.
Abstract Human–wildlife conflict (HWC) around protected areas endangers lives and damages livelihoods. It also erodes support for conservation. Yet most mitigation efforts fail to gain the sustained community support needed for long‐term success. We drew on 758 one‐to‐one semi‐structured interviews, supplemented by focus groups, practitioner interviews

Xanthatin‐13‐(Pyrrolidine‐2‐Carboxylic Acid), a Sesquiterpene Lactone Isolated From Burdock Leaf, Attenuated Aβ25‐35 Toxicity and Memory Deficits in a Pharmacological Mouse Model of Alzheimer's Disease

open access: yesPhytotherapy Research, Volume 40, Issue 5, Page 2824-2843, May 2026.
ABSTRACT Alzheimer's disease (AD) is a severe form of dementia, which occurrence increases with age and lifestyle conditions. It is characterized by amyloid protein accumulation forming senile plaques, hyperphosphorylated tau protein forming neurofibrillary tangles, neuroinflammation, and oxidative stress, leading to synapse loss and cell death ...

Seed source climate and precipitation timing determine dryland tree recruitment in hot and dry range margins

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Using a common garden study with experimental seasonal precipitation regimes, this study shows that intraspecific phenotypic variation mediates the effect of seasonal drought on Pinus monophylla recruitment, suggesting that different populations may respond uniquely to changes in climate.
