Google scholar: 1631 citations; i10-index of 47

According to my Google Scholar profile my research has to date attracted a total of 1.631 citations (+19 since May 28th). This includes 73 citations so far in 2026 (+9 since May 28th). My h-index remains 22 while my i10-index is now 47 (+1 since May 28th). My i10-index means that 47 of my texts have at least 10 citations each.

My latest articles/chapters to reach 10 citations are:

"Agency in biosemiotics and enactivism" (2016)

"Outline of an Uexküllian bio-ontology" (2001) - my very first scientific article

Google Scholar status per summer 2012 vs. autumn 2018

As of June 2012 - according to an old note - Google Scholars (cf. my profile) listed 19 academic articles of mine, which were in total cited 32 times, and I had an h-index of 3 (meaning that 3 of my articles had been cited at least 3 times each).

6 year on, I have according to Google Scholar been cited 324 times, and I have an h-index of 9 (up 1) as well as an h10-index of 9 (up 1; meaning that 9 of mine articles have been cited at least 10 times each). This is up 12 since August 20th. My 9th article to reach 10 citations is "Outline of an Uexküllian bio-ontology", my very first academic article, published in 2001.

Uexkullian Bio-Ontology paper cited in Castro´s doctoral thesis

My paper

Excerpt (p. 30, incl. footnote 80):

La interrelación de la red biosemiótica de conceptos utilizados aquí – membrana, signo, sitio activo, función, metabolismo, organismo, Umwelt, nichos, etc. – constituye una ontología regional (Husserl) de biología y semiótica, y de toda la biología, incluso la mayoría de las posibles interpretaciones reduccionistas80. 

80. Esto va en contra del argumento de Morten Tønnessen (2001) que afirma que los conceptos universales de la biología es imposible, porque podríamos imaginar formas de vida completamente diferente de las que conocemos. La generalización aquí puede caer en una falacia donde las condiciones no deban de cumplir con los requisitos conceptuales expuestos. En el caso de conocer una forma contrapuntística de vida diferente a la organizada a través del carbono podría ofrecer (o no) una negación a este argumento.

Roughly translated to English:

The interrelation of the biosemiotic network of concepts used here - membrane, sign, active site, function, metabolism, organism, Umwelt, niches, etc. - constitutes a regional ontology (Husserl) of biology and semiotics, and (all) biology, including most possible reducionist interpretations80. 

80. This goes against the argument of Morten Tønnessen (2001) who states that universal concepts of biology is impossible, because we could imagine ways of life completely different from those we know. This generalization can fall into a fallacy when conditions do not meet the conceptual requirements set. In the case we get to know about different ways of organizing life than carbon-based life forms, this might (or might not) offer a rejection of this argument.
