On a global scale, what are the methods of eradication of allochthonous species that reduce the original biodiversity of the host territories?

Some introduced species become pests that can reduce the biodiversity of host sites and sometimes block ecosystem changes.

Do you have in your scientific networks examples of vegetation inversions due to topography or ecosystemic evolution?

The inversions of vegetation seem to allow the increase of phytocenotic biodiversity. The main factors are often ecosystem topography and evolution.

Introduced invasive species are dangerous for the biodiversity of the host territories. When is it on the scale of several hundred years?

Ecosystem processes are not linear and are difficult to characterize.

What do you think of the concept of ecosystem inertia?

In other words, some ecosystems would ensure their perennity when the original conditions of their genesis no longer exist? This could explain some observable ecosystem weaknesses of our day in...

How to estimate the importance of ecological locks in the processes of potentiation of the invasive species?

The development of invasive species is often related to the regression of ecosystems.

Can we recognize signs of the "volatility clustering" property of a time series in its time domain plot?

My purpose is to recognize the volatility clustering property without statistical tests such as The Lagrange Multiplier (LM) test.

How to use Remote sensing and GIS applications for mapping the available medicinal plants within the locality/municipality?

Hello, I'm very interested in mapping and managing the conservation of the Philippine traditional medicinal plants, in which I think is very helpful in the field of medicine for further analysis...

How to overcome convergence issues in concrete arch models?

Hi, I have modelled a three-span arch bridge with soil fill over along with pedestals. The FE modelling is done in LUSAS with HX8M solid elements (i.e. 3D solid modelling). The non-linearity is...

Can medicinal plants really play an inherent rule in the COVID-19 tackle?

Numerous scientific reports cited plant extracts with potential antiviral activity and even anti-COVID-19? Why these findings are neglected? I remember very well the warning released by the WHO to...

What are damage parameters for SMA while modelling on ABAQUS 2020?

I have given Elastic and Superelastic material properties, but I think we need to provide the damage parameters also. Please help me here.

Is there any solar electric power plant having the concentrated photovoltaic modules?

The solar photovoltaic (PV) power plant uses commercial (non-concentrated) PV modules which are quite simple in design and reliable. They can work on fixed orientation and don't need the moving...

Is it possible estimating environmental conditions with a Bayesian approach?

In ecology specific species can be used to get an indication/estimation of the environmental conditions. A simplistic example, lets assume I find a pike (Esox lucius). We know this species does...
