News from an Ecosystem (by Diego Fdez-Sevilla)

When we relate with meteorological phenomena, usually we tent to do it from the contrast that we feel between the interior of our Houses, cars and offices when compared with the exterior. So we don´t really see what the real contrast happens through an entire period outdoors. In another words, we don´t feel the contrasts that affect our ecosystems.

Temperature amplitude is the difference between Maximum and  Minimum temperature registered in a cycle. It can be annual, inter-seasonal or daily max and min. And, since we spend most of our time indoors throughout some parts of any of those cycles, this value reflects the contrast in temperature to which natural ecosystems are exposed to meanwhile we might be using central heating or air conditioners.

One example of such contrasts can be seeing as a recent heat wave has hit Spain (Lat 35-43N) with record breaking  temperatures for this part of the year, reaching as high as 42.9C on 14th May Thursday  in the province of Valencia. But that’s not all, after that, on the 18th of May, polar-maritime air masses have moved towards Spain provoking a sudden and fast drop in Temperatures.

The steepest drop in Temperature has been recorded on Monday 18th May with Max average Temp of 29C and Min of 6C in the province of Valladoliz, giving a 23C contrast.

The intrusion of this cold mass of air was preceded by a extremely warm mass of air, creating extreme variations in the maximum temperature recorded between Monday and Tuesday.

Maximum temperature variation for Tuesday 19th May in the Peninsula and Balearic Islands compared with previous day Monday 18th May.

And altogether, this contrast created between a vary warm mass of air and a very cold mass of air has created an instability in the atmosphere that has led to meteorological events generating large hail and flash floods.

Closing remarks

The repercussions from these extreme contrasts in temperature is something that not only originates discomfort for humans and an economic repercussion in the agricultural sector. The impact over the performance of the ecosystem is a matter yet to be fully understood as part of the synergistic interaction that exists between Ecosystems and the atmosphere above them.

One hypothetical example from experiencing an increase in frequency for such type of atmospheric contrasts: a heat wave activates the metabolism of dormant pollinating insects and larvae as well as flowering in plants. After, a cold front arrives decimating the population of insects and damaging flowers. The pollination process gets interrupted when at the same time, plants and insects have already spent resources through its activation. If this event happens more frequently, the resources to reactivate the pollination process might not be enough to develop new flowers as well as insects might have not had time enough to regenerate the population, or just get out of season. A decrease in the population of insects would affect pollination and birds population as well as many reptiles, and all the way up the food chain in the animal kingdom. Plants would see reduced their capacity to reproduce due to a weak pollination process and from having less animals to disperse their seeds. At the same time, when a surface of land covered with plants reduce water losses in the soil and increases the rates of precipitation as a result of evapotranspiration processes and the release of particles, a decrease in the percentage of land covered by plants induce the opposite, affecting meteorological processes in the long run.

Altogether I think that this is a very plausible scenario to be contemplated in today’s debate about possible alterations in atmospheric circulation.

(This post is part of a more complex piece of independent research. I don´t have founding, political agenda or publishing revenues from visits. Any scientist working in disciplines related with the topics that I treat in my blog knows how to judge the contribution that my work could potentially add to the state of knowledge. Since I am in transition looking for a position in research, if you are one of those scientists, by just acknowledging any value you might see from my contribution, would not only make justice to my effort as independent researcher, but ultimately, it will help me to enhance my chances to find a position with resources to further develop my work.

I believe that the hypothesis that I have presented in previous posts in this blog (here, here and here) could help to understand present and possible future scenarios in atmospheric circulation. However, this is an assessment based on observation which needs to be validated throughout open discussion and data gathering. So please feel free to incorporate your thoughts and comments in a constructive manner.

If you feel like sharing this post I would appreciate to have a reference about the place or platform, by private or public message, in order for me to have the opportunity to join the debate and be aware of the repercussion which might generate d.fdezsevilla(at)

For anybody interested in the posts related with this discussion here I leave you those more relevant in chronological order (there are comments bellow some of them. Please check them out):

Bachelor in General Biology, Masters degree "Licenciado" in Environmental Sciences (2001, Spain). PhD in Aerobiology (2007, UK). Lived, acquired training and worked in Spain, UK, Germany and Poland. I have shared the outcome from my work previous to 2013 as scientific speaker in events held in those countries as well as in Switzerland and Finland. After 12 years performing research and working in institutions linked with environmental research and management, in 2013 I found myself in a period of transition searching for a new position or funding to support my own line of research. In the current competitive scenario, in order to demonstrate my capacities instead of just moving my cv waiting for my next opportunity to arrive, I decided to invest my energy and time in opening my own line of research sharing it in this blog. In March 2017 the budget reserved for this project has ended and its weekly basis time frame discontinued until new forms of economic and/or institutional support are incorporated into the project. The value of the data and the original nature of the research presented in this platform and at LinkedIn has proved to be worthy of consideration by the scientific community as well as for publication in scientific journals. However, without a position as member of an institution, it becomes very challenging to be published. I hope that this handicap do not overshadow the value of my achievements and that the Intellectual Property Rights generated with the license of attribution attached are respected and considered by the scientist involved in similar lines of research. **Any comment and feedback aimed to be constructive is welcome as well as any approach exploring professional opportunities to be part of.** In this blog I publish pieces of research focused on addressing relevant environmental questions. Furthermore, I try to break the barrier that academic publications very often offer isolating scientific findings from the general public. In that way I address those topics which I am familiar with, thanks to my training in environmental research, making them available throughout my posts. (see "Framework and Timeline" for a complete index). At this moment, 2017, I am living in Spain with no affiliation attachments. Free to relocate geographically worldwide. If you feel that I could be a contribution to your institution, team and projects don´t hesitate in contact me at d.fdezsevilla (at) or consult my profile at LinkedIn, ResearchGate and Also, I'd appreciate information about any opportunity that you might know and believe it could match with my aptitudes.
