Input Output Analysis Foundations And Extensions

Losses of natural and semi-natural forests, mostly to agriculture, are a significant concern for biodiversity. Against this trend, the area of intensively managed plantation forests increases, and there is much debate about the implications for biodiversity. We provide a comprehensive review of the function of plantation forests as habitat compared with other land cover, examine the effects on biodiversity at the landscape scale, and synthesise context-specific effects of plantation forestry on biodiversity. Natural forests are usually more suitable as habitat for a wider range of native forest species than plantation forests but there is abundant evidence that plantation forests can provide valuable habitat, even for some threatened and endangered species, and may contribute to the conservation of biodiversity by various mechanisms. In landscapes where forest is the natural land cover, plantation forests may represent a low-contrast matrix, and afforestation of agricultural land can assist conservation by providing complementary forest habitat, buffering edge effects, and increasing connectivity. In contrast, conversion of natural forests and afforestation of natural non-forest land is detrimental. However, regional deforestation pressure for agricultural development may render plantation forestry a ‘lesser evil’ if forest managers protect indigenous vegetation remnants. We provide numerous context-specific examples and case studies to assist impact assessments of plantation forestry, and we offer a range of management recommendations. This paper also serves as an introduction and background paper to this special issue on the effects of plantation forests on biodiversity.

Plantation Forests and Biodiversity: Oxymoron or Opportunity?

Contents Summary 1108 I. Introduction 1108 II. Mycorrhizal plant diversity at global and local scales 1108 III. Mycorrhizal evolution in plants: a brief update 1111 IV. Conclusions and perspectives 1114 References 1114 SUMMARY: The majority of vascular plants are mycorrhizal: 72% are arbuscular mycorrhizal (AM), 2.0% are ectomycorrhizal (EcM), 1.5% are ericoid mycorrhizal and 10% are orchid mycorrhizal. Just 8% are completely nonmycorrhizal (NM), whereas 7% have inconsistent NM-AM associations. Most NM and NM-AM plants are nutritional specialists (e.g. carnivores and parasites) or habitat specialists (e.g. hydrophytes and epiphytes). Mycorrhizal associations are consistent in most families, but there are exceptions with complex roots (e.g. both EcM and AM). We recognize three waves of mycorrhizal evolution, starting with AM in early land plants, continuing in the Cretaceous with multiple new NM or EcM linages, ericoid and orchid mycorrhizas. The third wave, which is recent and ongoing, has resulted in root complexity linked to rapid plant diversification in biodiversity hotspots.

Globally, the quality of agricultural soils is in decline as a result of mismanagement and the overuse of agrichemicals, negatively impacting crop yields. Agaricus subrufescens Peck is widely cultivated as an edible and medicinal mushroom; however, its application in soil bioremediation and amendment remains insufficiently studied. In order to determine if A. subrufescens can positively impact agricultural soils, we designed two experiments: the first, a glasshouse experiment investigating the ways in which A. subrufescens production alters soil nutrients and soil health; the second, a laboratory experiment investigating if A. subrufescens can degrade beta-cypermethrin (β-CY) and glufosinate ammonium (Gla), two widely used agrichemicals. The glasshouse experiment results indicated that the use of compost and compost combined with A. subrufescens led to increases in soil organic matter, nitrogen, phosphorus, and potassium compared to the control treatments (sterilized soil). However, the incorporation of A. subrufescens with compost resulted in significantly greater levels of both available nitrogen and available phosphorus in the soils compared to all other treatments. Laboratory experiments determined that the mycelium of A. subrufescens were unable to grow at concentrations above 24.71 μg/mL and 63.15 μg/g for β-CY and Gla, respectively. Furthermore, results indicated that fungal mycelia were able to degrade 44.68% of β-CY within 15 days, whereas no significant changes were found in the concentration of Gla. This study highlights that cultivation of A. subrufescens may be a sustainable alternative for the rehabilitation of agricultural soils, whilst providing an additional source of income for farmers.

The Use of Agaricus subrufescens for Rehabilitation of Agricultural Soils

In the present study, a new species, Scolecohyalosporium thailandense, is introduced based on morphological and molecular approaches. The species was found as a saprobe occurring on Imperata sp. (Poaceae) in terrestrial habitats in Chiang Rai Province, Thailand. This species is characterized by solitary, semi-immersed to erumpent, subglobose to ampulliform, papillate ascomata, dark brown pseudoparenchymatous peridium, fissitunicate, cylindrical to subcylindrical asci embedded in a hyaline, filamentous to cellular pseudoparaphysate hamathecium, and filiform, yellowish, septate ascospores. Phylogenetic analyses based on a concatenated ITS, LSU, SSU, and TEF1-α sequence matrix demonstrated that S. thailandense formed a well-resolved clade with S. submersum (the type species of this genus) and Scolecohyalosporium sp. within the Parabambusicolaceae. Therefore, S. thailandense is introduced herein as the second species of the genus Scolecohyalosporium. Morphological characteristics, illustrations, and updated phylogenetic analyses are provided, and notes on species distinctiveness with closely related taxa are discussed.

The invention provides a fungus strain A. flavus G10 for degrading polyurethane plastic. The microorganism preservation number of the fungus strain A. flavus G10 is GDMCC 60537. The invention also provides a method for culturing the fungus strain A. flavus G10. The method includes the steps of isolating the fungus strain from the intestinal tract of a cricket; adopting PU as a unique carbon sourcefor culturing the fungus strain in a liquid culture medium to obtain a culture solution; diluting the culture solution and coating a solidified nutrient agar culture medium containing tetracycline antibiotics and a potato glucose agar culture medium with the culture solution to obtain cultured growing products. The cultured growing products are subcultured on fresh plates at 30 DEG C until a single fungus strain is obtained on each plate. The fungus strain A. flavus G10 can degrade the polyurethane plastic quickly.
