Identification of priority areas is a fundamental goal in conservation biology. Because of a lack of detailed information about species distributions, conservation targets in the Zhoushan Archipelago (China) were established on the basis of a species-area-habitat relationship (choros model) combined with an environmental cluster analysis (ECA). An environmental-distinctness index was introduced...

Recent estimates reaffirm that conservation funds are insufficient to meet biodiversity conservation goals. Organisations focused on biodiversity conservation therefore need to capitalise on investments that societies make in environmental protection that provide ancillary benefits to biodiversity. Here, we undertake the first assessment of the potential ancillary benefits from the ballot box i...

Background: Attention to environmental literacy and ethics in agriculture has a decisive role in nature conservation and production resources. If farmers do not have environmental literacy, irreparable damage to the environment is expected. The purpose of this study was to evaluate environmental literacy and its relationship with environmental ethics among farmers in Torbat-e-Heydariyeh. Metho...

Despite numerous ecological studies with mosquitoes, it remains unclear what environmental factors are the most important determinants of structure, species richness, and abundance of mosquito assemblages. In the current study, we investigated relations between these characteristics of mosquito larvae assemblages and environmental factors in a large set of different habitats. Particular objecti...

Rapid biodiversity assessment and conservation planning require the use of easily quantified and estimated surrogates for biodiversity. Using data sets from Québec and Queensland, we applied four methods to assess the extent to which environmental surrogates can represent biodiversity components: (1) surrogacy graphs; (2) marginal representation plots; (3) Hamming distance function; and (4) Syr...

Understanding microbial interactions is essential to decipher the mechanisms of community assembly and their effects on ecosystem functioning, however, the conservation of species- and trait-based network interactions along environmental gradient remains largely unknown. Here, by using the network-based analyses with three paralleled data sets derived from 16S rRNA gene pyrosequencing, function...
