Summary: The application of dehydrated sewage sludge as fertilizer for Acacia mangium plants led to higher abundance of phytophagous insects and tending ants, with similar levels of predators. However, the diversity of ant species was lower in fertilized plants, while a greater variety of insects were more abundant on these plants. This indicates the potential of using dehydrated sewage sludge to recover degraded areas.

Summary: Recent studies have shown that global declines in insects and their relatives may be caused by increased inputs of nitrogen and phosphorus. This study synthesized the effects of nutrient enrichment on the abundance of hexapods and arachnids, finding significant decreases in these groups overall. The negative effects of nutrient additions were stronger for sensitive aquatic insects and affected both above-ground and below-ground arthropods.

Summary: Litter decomposition is a crucial process for nutrient cycling and carbon budgets in mixed forests. However, there is limited knowledge about the response of soil microbial processes to the mixed-litter decomposition of fresh leaf, semi-decomposed leaf, and fine root. In this study, a laboratory microcosm experiment was conducted to investigate the effects of mixed-litter decomposition on soil enzyme activity and microbial community in a karst forest in Southwest China. The results showed that the presence of fresh leaf litter had a significant influence on mixed-litter decomposition and soil enzyme activity. Furthermore, litter N concentration and the initial quality of litter played important roles in the decomposition process.

Summary: Marine litter surveys were conducted to investigate the role of mangroves in collecting litter. The average litter density in the mangroves was 0.088 +/- 0.076 items m-2, with plastic being the predominant material (85.9%). The middle zone had higher litter densities (0.162 +/- 0.150 items m-2) compared to the landward (0.066 +/- 0.049 items m-2) and seaward zones (0.036 +/- 0.028 items m-2), indicating its importance in collecting litter from both land and sea. The landward zones predominantly trapped heavier litter that could be caught by mangrove roots (e.g., plastic and clothing), while the middle zones retained soft plastics and other litter that would not easily get trapped in the roots, and the seaward zones acted as a sink for litter from marine and fishing activities.

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: The distribution and composition of tree species in Amazonian forest fragments are influenced by the level of human-induced disturbance and forest fragment size. The severity of disturbance can be better understood by analyzing floristic and phytosociological parameters of tree communities in forest fragments. The differences in floristic, distribution, and successional stages of trees were investigated in two forest fragments in the deforestation arc of the Amazon. Evaluation of the two areas revealed higher numbers of individuals, species, and diversity index in the preserved fragment, attributed to lower alterations compared to the altered fragment. The Fabaceae family had the highest number of species, while the Protium altissimum (Aubl.) Marchand had the highest importance value in both areas. The total number of late secondary species was 26 in area I and 34 in area II. One threatened species was found in the preserved area. The tree communities in area II exhibited higher diversity index, number of species, number of individuals, and number of secondary species.

Summary: The aim of this study was to evaluate the morphological differences between leaves of different growth stages and ages in Eucalyptus grandis and propose a visual phenological scale for leaf maturity. The study found that color, shape, and size of the leaves distinguished the first five leaf pairs, while anatomical analysis showed differences in tissue composition and thickness between mature and younger leaves. These anatomical changes coincide with the development of leaf resistance against the pathogen Austropuccinia psidii, suggesting a link between leaf maturation and reduced infection in older plants.

Summary: The main cotton pest in the Americas is the cotton boll weevil. Reproductive diapause can be induced in these weevils when they feed on alternative diets. This study found that prolonged feeding on alternative diets affects the reproductive tract of female and old male weevils differently, and these individuals may not be able to reverse the atrophy of their reproductive organs even after accessing cotton squares.
