Invasive alien plants (IAPs) are increasingly threatening biodiversity worldwide; thus, early detection and monitoring tools are needed. Here, we explored the potential of unmanned aerial vehicle (UAV) images in providing intermediate reference data which are able to link IAP field occurrence and satellite information. Specifically, we used very hi...

Mediterranean landscapes constitute a biodiversity hotspot where species distribution and composition have been shaped by a long history of traditional land use. In this work, we investigated the effects of landscape patterns on community composition and the functional, morphological, and ecological traits of 21 small mammal species in the Mediterr...

The European Union (EU) aims at reaching carbon neutrality by 2050. Within the land use, land-use change, and forestry (LULUCF) sector, forestry will contribute to this target with CO 2 sink, harvested wood products (HWP), and use of wood for material or energy substitution. Despite the fact that the forest sink currently offsets about 9% of the to...

Remote Sensing (RS) is a useful tool for detecting and mapping Invasive Alien Plants (IAPs). IAPs mapping on dynamic and heterogeneous landscapes, using satellite RS data, is not always feasible. Unmanned aerial vehicles (UAV) with ultra-high spatial resolution data represent a promising tool for IAPs detection and mapping. This work develops an op...

Combining field collected and remotely sensed (RS) data represents one of the most promising approaches for an extensive and up-to-date ecosystem assessment. We investigated the potential of the so called spectral variability hypothesis (SVH) in linking field-collected and remote-sensed data in Mediterranean coastal dunes and explored if spectral d...

Most research on small mammal decline focused on limited spatial and temporal scales, especially for the Mediterranean region. Landscape fragmentation and degradation are considered the main drivers of biodiversity loss, yet the synergetic effect of landscape change and biotic interactions on small mammal assemblages have been poorly investigated....

Quantification of niche overlap represents an important topic in several aspects of ecology and conservation biology, although it could be potentially affected by imperfect detection, i.e., failure to detect a species at occupied sites. We investigate the effect of imperfect detection on niche overlap quan-tification in two arboreal rodents, the ed...

In the last decades, wildfires have considerably changed in their frequency, extension, intensity and this is mainly due to climate change and human activities. The year 2017 was particularly significant for the amount of hectares burned in Southern Europe and especially in Italy. Remote sensing has been used to map and monitor wildfires around the...

Global warming is considered one of the major human-induced threats to ecosystem resilience. In particular, processes involving the adaptation capacity of forest ecosystems and the role of forest management to improve mitigation strategies still need to be understood more deeply. Hence, a multiscale framework highlighting the linkages between adapt...

In the Mediterranean sandy coasts urban growth largely occurs to sustain sea-side tourism, causing a severe loss of natural coastal dune habitats and the related ecosystem services. During the last half-century coastal dunes integrity has been widely altered by land use change; however, procedures and study cases assessing how in particular their c...

Small mammal communities in European forests stresses their potential use as bioin- dicators. However, to effectively study the role of small mammals as biondicators, an accurate assessment of species detection is crucial, as sampling biases can misrepresent abundance and niche estimates. We explored detection probability and niche overlap in two E...

We propose a procedure to detect significant changes in forest spatial patterns and relevant scales. Our approach consists of four sequential steps. First, based on a series of multi-temporal forest maps, a set of geographic windows of increasing extents are extracted. Second, for each extent and date, specific stochastic simulations that replicate...

In the Mediterranean area, high-elevation habitats are represented by a few iso- lated peaks hosting a high number of endemic and rare plants (e.g., Pauli et al. 2003, 2007; Gutierrez-Giro and Gavilan 2010), most of them at risk for local extinction as a consequence of climate warming (e.g., Grabherr et al. 1994). In this context, the most endanger...

Question
Hi,
I'm analysing a dataset containg XY data and I would like to fit a curve to my data.
My intention is to model the response of Y as a function of X. The function I'm looking for should have the following characteristics:
- The y value should be bounded between a minimun (0) and a maximum value (100)
- decreasing function with high Y values at low X value
- an inflection point where the function decreases slower until reaching an horizontal asymptote.
I'm intersted in estimating two important parameters: the asymptote and the inflection point
The function should be similar a sigmoid function (e.g. Weibull model which allows to estimate the asymptote, the scale (inflection point) and the shape (the growth rate) of the curve) but with a decreasing trend (as opposed to a sigmoidal function).
Thank you!
Question
I would like to analyze data from different LTER sites in order to evaluate the effect of climate change on different ecosystems. The problem is that each site collected data with different study design and with different response variables (diversity of different taxa, variations in snow cover, biogeochemical cycles, ecc.).
