Soil fauna are critical for ecosystem function and sensitive to the changes of soil fertility. The effects of fertilization on soil fauna communities, however, remain poorly understood. We examined the effects of fertilization form and quantity on the abundance, diversity and composition of soil fauna across an age-sequence of poplar plantations (i.e., 4-, 9- and 20-yr-old) in the coastal regio...

Assessing the ecological status, a concept implemented in the European Water Framework Directive [EC, 2000. Directive of the European Parliament and of the Council 2000/60/EC establishing a framework for community action in the field of water policy PE-CONS 3639/1/00, p. 72], requires the application of methods capable of distinguishing different levels of ecological quality. The Average Taxono...

In Indonesia, transgenic products are still considered innovative, and genetically modified (GM) maize has stayed on the market while its impact environmental biosafety is now being evaluated. Bt corn been recognized as one of solutions to problem Asian cob borers preserve production. Therefore, this study aimed investigate effect arthropod richness diversity in a limited testing field using ra...

There is increasing interest in using natural enemies to control pests urban green spaces, but this often hampered by a lack of information on particular pest groups. Here we provide an assessment for the first time seasonal population coccid species and its Chamaecyparis lawsoniana (A. Murray) Parl, 1864. The main pest, Planococcus vovae (Nasonov, 1909), attacked parasitoids predators. Accordi...

Just like any other ecosystem, coastal and estuarine ecosystems are complex and dynamic in terms of their species structure and functioning. The resilience of the different types of coastal ecosystem to change depends on the structural complexity of the different trophic relationships within the local food web, the connectivity between habitats and larger (eco)system units, and the ecological a...

We studied the heterogeneity of soil weed seed-bank in a rice-wheat rotation system after long-term application of different organic or non-organic fertilizers, and the effects of major nutrients on the characteristics of the weed seed-bank. The soil was sampled in the Taihu area after a 31-year long-term fertilization experiment. Weed seeds were identified and counted in the surface soil of 12...

La restauración con especies nativas del Matorral espinoso tamaulipeco (MET) se está realizado dado el alto grado de degradación que sufre este ecosistma. En presente estudio, evaluó la vegetación porte y regeneración en un área MET posterior a 5 años ser restaurado. A cada individuo, le midió altura total, diámetro basal copa, sitios 200 m2 para arbórea arbustiva, 1 regeneración. Se determinó ...

The present study mainly focused on the diversity of spider fauna in agro-ecosystem Mahabubnagar district during Kharif and Rabi seasons 2020-21. sampling was collected at monthly intervals by different methods (in situ counts, net sweeping, pitfall traps litter sampling). A total 30 species were identified which, Araneidae family is represented 8 belonging to four genera followed Salticidae (5...
