General Systems Theory (GST) has been an attempt to put precision into the term system thereby making intelligent communication between its users more attractive, something that provides for migration of ideas and the possible resolution of issues by borrowing solutions from unfamiliar domains. We propose to build on GST and in particular, as von Bertalanffy once did, draw on the biological sci...

The philosophical logic developed by the Franco-Romanian thinker Stéphane Lupasco (Bucharest, 1900 – Paris, 1988) includes a systems approach to epistemology that complements independent work of von Bertalanffy and other general systems theorists. Basing his theory primarily on quantum mechanics, Lupasco proposed that the fundamental dualistic antagonism present in energy and accordingly in all...

The age and growth of the blackspot seabream, Pagellus bogaraveo, were determined by examining sagittal otoliths from fish sampled in eastern Adriatic Sea. A total 674 specimens (181 males, 90 hermaphrodites, 108 females, 295 immatures) ranging 8.80 to 47.27 cm (21.93 ± 9.00 cm) length analyzed. maximum observed for whole sample was 13 years. dominated 1-year-old as a consequence an abundance j...

Longitudinal data on individual growth and seasonal changes in body mass, girth, blubber thickness are rarely available for cetaceans, making it difficult to assess their population composition nutritional condition. During different time intervals from 1997 2020, we collected longitudinal length, girth,and seventeen harbour porpoises (Phocoena phocoena) human care. We compared Gompertz von Ber...

—Most anurans exhibit sexual size dimorphism (SSD). This morphological variation between the sexes may be attributed to different ages at maturity, growth rate, or longevity. We present the first data on age structure and growth pattern of Hypsiboas cordobae using skeletochronology, and analyze SSD considering age-specific differences in body size based on 71 individuals. Snout-vent length (SVL...

Population dynamics parameters and stock status of Squaliobarbus curriculus (Richardson, 1846) were analyzed from May to September 2021 in the Lanxi section Qiantang River. FiSAT II software program was used. The growth coefficient K = 0.21 year–1, asymptomatic length L∞ 39.48 cm, age at theoretical zero-length t0 –0.74 years estimated. von Bertalanffy function calculated as Lt 39.48[1 – e–0.21...

The Solow-Swan model is shortly reviewed from a mathematical point of view. By considering non-constant returns to scale, we obtain general solution strategy. We then compute the exact for Cobb-Douglas production function, both classical and von Bertalanffy model. Numerical simulations are provided.
