Lornoxicam-loaded chitosan-coated Litsea lipid nanocarriers (LRX-CS-LLCs) were developed as an innovative oral delivery system, combining the synergistic anti-inflammatory effects of Litsea cubeba oil with the mucoadhesive properties of chitosan. The GC/MS analysis of Litsea cubeba oil identified α -citral (47.56%), β -citral (26.86%), and D -limonene (14.00%). Various LRX-loaded LLCs were prepared and optimized. Fourier trans...
Phosphorus (P) fertilizers augment agricultural production despite their adverse environmental impacts, as they deplete plants of P through frequent soil P fixation. Therefore, this study investigated and characterized the potential alternative, phosphate-solubilizing Pseudomonas lurida (Pl) "OR400772" from the alfalfa rhizosphere. The in vitro characterization of P solubilizing activity on Pikovskaya’s (PVK) media, in additio...
Positive Feedback on Climate Warming by Stream Microbial Decomposers Indicated by a Global Space‐For‐Time Substitution StudyNARA Subscribed
Decomposition of plant litter is a key ecological process in streams, whose contribution to the global carbon cycle is large relative to their extent on Earth. We examined the mechanisms underlying the temperature sensitivity (TS) of instream decomposition and forecast effects of climate warming on this process. Comparing data from 41 globally distributed sites, we assessed the TS of microbial and total decomposition using lit...
Purpose: Based on its crucial regulatory role in several biochemical processes, potassium (K) is considered to greatly influence fruit yield and quality. Methods: Two field experiments were carried out in two seasons (2021 and 2022) to explore the response of lemon (Baladi cv.) trees grown in K-deficient soil to four different K fertilizer sources applied individually as a foliar spray. K citrate (KC 1 = 1.3 vs. KC 2 = 2.6 g L...
FreshLanDiv : A Global Database of Freshwater Biodiversity Across Different Land UsesNARA Subscribed
Motivation Freshwater ecosystems have been heavily impacted by land‐use changes, but data syntheses on these impacts are still limited. Here, we compiled a global database encompassing 241 studies with species abundance data (from multiple biological groups and geographic locations) across sites with different land‐use categories. This compilation will be useful for addressing questions regarding land‐use change and its impact...
Environmental salinity is an important abiotic factor that directly affects the growth, metabolism, osmoregulatory processes, and physiological performance of fish. Herein, the effects of long-term salinity stress on juvenile Pangasianodon hypophthalmus have been evaluated. Fish were allotted in five triplicate groups and exposed to five different salinities (0.0, 4.0, 8.0, 12.0, and 16.0‰) for 56 days. After exposure, the fin...
Motivation Aquatic insects comprise 64% of freshwater animal diversity and are widely used as bioindicators to assess water quality impairment and freshwater ecosystem health, as well as to test ecological hypotheses. Despite their importance, a comprehensive, global database of aquatic insect occurrences for mapping freshwater biodiversity in macroecological studies and applied freshwater research is missing. We aim to fill t...
The present study evaluated the impacts of powdered Astragalus membranaceus extract (AME) on the growth, physiological responses, and serum immunity of Pangasianodon hypophthalmus juveniles. Four test diets were formulated to include varying AME levels as 0.0 (control), 1.5 (AME1.5), 3.0 (AME3.0), and 4.5 (AME4.5) g/kg. Fish weighing approximately 11.50 g were stocked into four triplicate groups and hand-fed on the test diets...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
