Summary: The nutrient cycling in deserts is dependent on moisture, but macro-arthropods play a key role in accelerating the recycling rate of plant litter nutrients and explaining how desert plants receive nutrients when the soil is dry. Their burrowing activity alters the microtopography and enhances productivity and species diversity in the otherwise poor desert environment, making them key regulators of nutrient dynamics in drylands.

Summary: Supplementary feeding can have both positive and negative effects on bird populations. In the western part of Amsterdam, bread is the main type of supplementary food offered, attracting juvenile gulls and feral pigeons and potentially affecting biodiversity in the long term. The current nutritional imbalance and overabundance of food in the city highlights the need for more balanced feeding practices to prevent negative impacts on both animal and public health.

Summary: This study re-analyzed historical acarine morphological work using a model based on mechanics and added seven additional zoophagous mesostigmatid species. It found distinct differences in cheliceral design among predatory mesostigmatids with different feeding styles, as well as the impact of body size on predatory behaviors. The study also proposed possible feeding habits for certain uropodines based on their morphology.

Summary: The application of biochar and arbuscular mycorrhizal fungi is important for improving soil properties and plant growth. This study found that the combination of biochar and AMF significantly improved soil nutrient availability and root traits in rice, resulting in enhanced nutrient absorption capacity.

Summary: This study explores the molecular and neuronal mechanisms underlying the transition from feeding to courtship in Drosophila melanogaster. The results show that feeding is prioritized over courtship in starved males, but the consumption of protein-rich food rapidly reverses this order. A gut-derived neuropeptide hormone called Diuretic hormone 31 (Dh31) plays a role in switching from feeding to courtship. The findings also reveal that Dh31 stimulates specific brain neurons through the circulation, leading to the prioritization of courtship over feeding through parallel pathways.

Summary: Psittacidae is an endangered family of birds. This study analyzed the nutritional profiles of crop contents in different parrot species and found remarkable similarities in their nutritional compositions. The study also compared the nutritional content between hand-feeding formulas and parrot crop samples and found variations in certain nutrients. The findings suggest that a single formulation could be used for hand-rearing Ara and Amazona species, while a different formulation may be more appropriate for Rhynchopsitta species.

Summary: Research has shown that mixotrophic dinoflagellates play a significant role in global red tide events due to their ability to combine photosynthesis and predation. Species with low to moderate growth rates, but diverse prey, including diatoms, are responsible for causing red tides worldwide, indicating a strategy of exchanging growth for prey diversity.

Summary: Soft corals, such as Antillogorgia bipinnata, are colony building animals that feed by catching food particles brought by currents. Vibrations induced by VIVs can significantly enhance their ability to capture food particles, leading to up to 40% more particles being captured compared to fixed state.

Summary: Whale carcasses in the deep sea provide habitats for organisms and act as intermediate refugia for the dispersal and evolution of deep-sea organisms. Comparing whalebone assemblages to other deep-sea environments, the study found that nematode assemblages on whalebones resemble those from hydrothermal vents and cold seeps, suggesting the importance of organic falls for meiofauna from chemosynthetic environments. Furthermore, oceanographic conditions and the age of the carcasses can influence nematode assemblage composition and richness.

Summary: Single-stage deammonification (SSD) processes have been successful in treating high-strength NH4+ (>300 mg/L) using the step-feeding strategy, but struggle to treat moderate-strength NH4+ (100-300 mg/L). This study evaluated the effectiveness of the step-feeding strategy on the long-term stability of treating moderate-strength NH4+ using two SSD sequential-batch reactors (SBRs). The results showed that the one-step feeding SBR achieved higher nitrogen and COD removal efficiency compared to the multi-step feeding SBR, indicating the importance of maintaining an appropriate FA level to selectively suppress NOB activity throughout the operation.

Summary: Climate and agriculture experts advocate for the development of a carbon sink in soil to mitigate the impacts of climate change. A two-year field experiment in semi-arid tropical drylands tested sustainable nutrient management approaches to sequester carbon in the soil. The study found that biochar treatments resulted in higher organic carbon stock in the top layer of soil compared to compost treatments, and the biochar-based integrated nutrient management showed the maximum residual effect in chickpea crops. The findings suggest that an integrated approach of need-based fertilizer with biochar application could be a sustainable strategy for carbon sequestration and food security in semi-arid tropical drylands.

Summary: This study developed a simple, fast and reliable method for the determination of 20 free amino acids in honey samples. The method achieved accurate results through a dilute-and-shoot strategy and hydrophilic interaction liquid chromatography tandem mass spectrometry. The method demonstrated advantages such as short detection time, wide linear range, high sensitivity, and negligible matrix effect.

Summary: The study on Aacanthocnema dobsoni in Victoria from 2013 to 2015 revealed that the psyllid is monophagous on Allocasuarina verticillata, with high fecundity, multivoltinism, and adaptation to temperature changes. There were three generations per year with no evidence of diapause, indicating adaptability to seasonal variations.

Summary: Through studying Typhonium angustilobum and T. wilbertii, it was found that they are functionally specialized to trap saprophagous beetles and flies, respectively. The differences in floral scent and morphological features between the two species suggest that these floral traits are critical for attracting and filtering beetle or fly pollinators.

Summary: Fluctuations in insect herbivore abundance and damage severity are key factors affecting tree health. The Bell miner associated dieback involves eucalypt trees, psyllids, and bell miners. Psyllid abundances were higher in affected forests, but psyllid communities did not differ between forest types, contradicting a hypothesis on bell miner farming of psyllids. Psyllid communities differed among eucalypt host species, with Cardiaspina having a stronger negative relationship between canopy health and psyllid abundances.

Summary: Canopy leaves of Eucalyptus camaldulensis are more suitable for the survival and oviposition of Cardiaspina albitextura nymphs compared to understorey leaves. The diversity of foliar sugars and the abundance of ellagitannins influence the abundance of the psyllid nymphs.

Summary: Insect herbivores evaluate plants by integrating responses to external and internal cues mediated by physical and chemical traits. We studied the host assessment behaviors of the Eucalyptus-feeding psyllid, Glycaspis brimblecombei, on preferred and non-preferred hosts using video recordings, EPG technology, and histological examination. Our findings suggest that gustatory cues play a strong role in host acceptance, and that females can feed from both phloem and xylem. Rapid host assessment could be influenced by positive and negative stimuli, potentially caused by water-soluble polyphenolic compounds in non-vascular tissues.
