Introduction
My current research goal in order to achieve a synthetic approach in the fields of ecosystem ecology and econophysics is to complete and expand an empirically testable set of interdisciplinary models. These models, given their non-contingent, and scale-independent nature, should be equally valid to analyze the economic system and its essential interactions with the natural environment, by using a new theoretical framework equally valid for both sciences (ecology and economics).

Article
Full-text available
Scientific ideas and hypotheses may be accepted, refuted, criticized, or subject to rebuttal by researchers. Dogmas do not belong to the territory of science, and ending up in uncharted territories should be the most encouraging and hopeful achievement for a researcher. However, modern science is quite different than the ideal image of a scientist...
Article
Displaying an appropriate dispersal intensity (DI) in response to environmental fluctuations may determine if a given species goes extinct or not. Thus, developing indicators of the DI necessary to harness a given ecological niche breadth is urgent due to the changing latitudinal boundaries between the Earth’s great climate belts because of global...

Road networks alter the landscapes, increasing the ecosystem fragmentation and for this reason are associated with a significant impact in biodiversity. The main ecological effects of road networks on wildlife are related to a) habitat loss, b) direct disturbance by noise and artificial light, and especially by c) artificial barrier to animal movem...
Article
Through an extensive literature review and using a large dataset collected from several European studies, we explored the frequency of occurrence of road bird casualties. First, we modelled the inter-specific variation in roadkill’ frequency across the avian phylogeny, testing for phylogenetic signal. Then, we explored the association between frequ...
Article
A measure of health based on exact sciences is not considered by social sciences to evaluate human development. We propose the H measure of information of Shannon ([1948]. "A Mathematical Theory of Communication." The Bell Systems Technical Journal 27 (3): 379-423, 623-656), renamed as H cto , as a general indicator of human health which can be sub...
Article
There is a neglected old schism in ecosystem ecology (EE): the foundations of crucial concepts and principles of EE lie in thermodynamics, but the current mainstream of ecological thought is significantly biased towards contingent mathematical models disconnected from physics. Frequently, these models have weak theoretical support in ecology itself...
Article
From an econophysical point of view, this paper deals with a pivotal old topic that still remains paradoxically unsolved in economics: the relationship between labor and value under the influence of the second law of thermodynamics, in parallel to the relationship between value and price under the influence of market. With this aim, economic system...
Article
Full-text available
Mainstream ecological thought is explored in three sections: (i) Epistemological traits. Given the typical scientific development and the necessity of preserving our intellectual heritage, the conservatism outlined in (i) is cyclical, so its stages are graphically summarized. (ii) Methodological benchmarks antithetically derived from (i), in order...
Article
Conventional ecology lacks a non-contingent theory on the relationship between abiotic, biotic and anthropogenic factors under natural or quasi-natural conditions. As a result, since ecology is the science that studies the interaction between ecological factors in nested complex systems, we should recognize that ecology needs significant enhancemen...
Article
The emergence of organic biophysics of ecosystems (OBEC: an interdisciplinary approach supported by thirteen previous articles in order to get a non-contingent explanation of ecosystem dynamics) may close the gap between the foundation of ecosystem ecology in classical thermodynamics and the paradoxical fact that conventional thermostatistics is cu...

We herein explore the connections between the current condition of ecology concerning to sustainable development and the statement of Rutherford regarding the importance of physics to understand sustainability and biological conservation. The recent emergence of organic biophysics of ecosystems (OBEC) may constitute a feasible alternative to fill t...

Full-text available
The theory of food chains, and therefore the assembly and modifications of trophic pyramids depending on environmental influences, is an essential part of modern ecosystem ecology. A general model of energy pyramids based on a fruitful but simple analytical connection between ecology and conventional physics has been proposed by Rodríguez et al. (2...
Article
The Darwinian interpretation (Di) of evolutionary process, and its subsequent development in the form of modern evolutionary synthesis (MES), plays a paradigmatic role in the mainstream biological thought. However, the main role in the improvement from Di to MES has depended on population genetics. Conventional ecosystem ecology has added relativel...

Traditionally, islands have been used as ecological and biogeographical models because of their assumed ecological simplicity, reduced ecosystem size and isolation. The vast number of Earth's oceanic islands play a key role in maintaining global biodiversity and serve as a rich source of evolutionary novelty. Research into the factors determining d...

There has been a categorically unresolved crucial question in ecology and evolutionary theory for many decades; perhaps from the times of Charles Darwin himself: Is it possible, under natural conditions,that two species can perform a commonly shared ecological niche? There are two extreme conventional responses that have kept divided the scientific...
