Advantages of combining generalized linear models and occupancy models to find indicators of habitat selection: Small mammals in agroecosystems as a case study
01. Februar 2018
Publication date: February 2018 Source:Ecological Indicators, Volume 85 Author(s): Irene L. Gorosito, Mariano Marziali Bermúdez, María Busch Models of habitat variables can be used to find indicators for a quantitative prediction of the likeliness of species occurrence or abundance. Methodological bias due to variable detectability can be critical to properly determine habitat use and, thus, for understanding species ecology, distribution, and requirements for survival. In spite of recent advances in dealing with imperfect detection through detailed modeling, this approach...

Publication date: January 2018 Source:Ecological Indicators, Volume 84 Author(s): Alberto Doretto, Elena Piano, Francesca Bona, Stefano Fenoglio Excessive fine sediment accumulation (i.e., siltation) in streams and rivers originates from several human activities and globally results in heavy alterations of aquatic habitats and biological communities. In this study the correlation between fine sediment and several benthic invertebrate community metrics was tested through a manipulative approach in alpine streams, where siltation mainly results as a physical alteration (i.e., the...
A functional approach to Hill's numbers for assessing changes in species variety of ecological communities over time
01. Januar 2018
Publication date: January 2018 Source:Ecological Indicators, Volume 84 Author(s): Fabrizio Maturo, Tonio Di Battista Humans are dependent on a large number of species of animals, plants, fungi, and microbes that provide indispensable ecosystem functions and produce essential goods. Apart from the economic valuation of the direct and indirect benefits of biodiversity, people place existence values on biodiversity, i.e. they consider the existence of particular species, regardless of the services they provide. There is also a general recognition that species diversity indicates the...
