Abstract

It is widely accepted that bivalve shell growth responds to environmental factors, however, few studies analyze the influence of biological drivers on growth, including reproduction. We evaluated the reproductive cycle of Callista chione as a potential driver of shell formation rate. C. chione is a commercially important species and due to its longevity (> 20 years) is an interesting target for sclerochronological studies. Sampling was conducted in two different environmental settings along the eastern Adriatic coast: Pag – a semi-enclosed bay, and Cetina – a coastal site near a river mouth. The monthly collection was carried out for a 18-month period from May 2014 until October 2015. Temperature was measured hourly, whereas Chl a and δ13CPOM were determined monthly. Satellite data for Chl a was also included in the study. The Gonadosomatic Index (GSI) was used as a unit of measure for variation in gonadal mass. The oxygen isotope composition of several shells (δ18Oshell), once converted into seawater temperature, was used to determine the duration of the main growth season. Minimum monthly temperatures differed by ca. 4°C between Pag and Cetina (8.9°C and 12.7°C, respectively), whereas maximum temperatures were similar. Chl a and δ13CPOM values showed distinct temporal trends. A clear seasonal cycle in GSI was observed, however, it was not synchronous between sites. In Pag, GSI started to increase in early spring and reached maximum values during the summer, with a main spawning peak in July. In Cetina, increasing GSI values were observed during winter reaching maximum values in early spring, whereas spawning took place on several occasions during late spring and summer. Based on δ18Oshell values, the fastest shell growth occurred between the winter and summer (> 70%). The difference in temperature ranges may explain the spawning lag observed between sites. The highest temperatures in Pag in 2015 coincided with the main spawning peaks, while in Cetina temperature was inversely related to the GSI throughout the year. A correlative allocation of energy to growth and reproduction was observed at both sites, with a decline in growth after spawning. The highest peaks in Chl a concentration occurred mostly between November and April, a period with an increase in production of gonads. During this period, an inverse relationship of Chl a and δ13CPOM values was observed. More positive δ13CPOM values, indicative of fresh material, were related to periods following the main spawning peaks when the GSI was low ; conversely, more negative values were observed during the most ripe stages and maximum spawning peaks. This suggests that the allocation of energy to growth was higher during earlier reproductive stages when nutrients were more abundant, followed by a shift of energy investment toward gonad production and a decrease in nutrients.

Abstract

International audience; This work extends the Vertex Approximate Gradient (VAG) discretization of multi-phase Darcy flow models in order to take into account discrete fracture networks (DFN). We consider the asymptotic model for which the fractures are represented as interfaces of codimension one immersed in the matrix domain with continuous pressures at the matrix fracture interface. Our discretization takes into account general polyhedral meshes, general discrete fracture networks, the anisotropy of the matrix and of the fracture permeability fields, and discontinuous rocktypes. Compared with Control Volume Finite Element (CVFE) approaches, the VAG scheme has the advantage to avoid the mixing of the fracture and matrix rocktypes at the interfaces between the matrix and the fractures, while keeping the low cost of a nodal discretization on unstructured meshes. The convergence of the scheme to a weak solution of the model is proved for arbitrary choices of the volumes at the nodal unknowns assuming the non degeneracy of the relative permeabilities and a network of planar fractures. Numerical experiments exhibiting the efficiency of the VAG discretization are presented for 3D two phase flow simulations in fractured networks with high permeability contrasts between the matrix and the fractures including an application to tight gas recovery.
