Abstract Jellyfishes represent a group of species that play an important role in oceans, particularly as food source for different taxa and predator fish larvae planktonic prey. The massive introduction artificial sound sources the oceans has become concern to science society. While we are only beginning understand non-hearing specialists like cephalopods can be affected by anthropogenic noises regulation is underway measure European water noise levels, still don’t know yet if impact may...
We investigated the cycle of sexual reproduction in a Mediterranean population Corticium candelabrum by light and electron microscopy, using non-destructive tissue sampling. Most individuals this hermaphroditic species engaged reproduction. The relationship between seawater temperature gametogenesis was not straightforward. Oogenesis, characterised long phase oocyte growth, continuous, with new oocytes appearing every single month year. Nevertheless, maximum production coincided declining...
There is a considerable lack of information concerning marine invertebrate sensitivity to sound exposure. However, recent findings on cuttlefish and octopi showed that exposure artificial noise had direct consequence the functionality physiology statocysts, sensory organs, which are responsible for their equilibrium movements in water column. Owing available data deep diving cephalopod species, we conducted comparative experiment one Mediterranean squid, Illex coindetii, European squid...
Optical methods, as fluorescence microscopy or hyperspectral imaging, are commonly used for plants visualization and characterization. Another powerful collection of optical techniques is the so-called polarimetry, widely to enhance image contrast in multiple applications. In botanical applications framework, spite some works have already highlighted depolarizing print that plant structures left on input polarized beams, potential polarimetric methods has not been properly exploited. fact,...
Abstract Optical microscopy techniques for plant inspection benefit from the fact that at least one of multiple properties light (intensity, phase, wavelength, polarization) may be modified by vegetal tissues. Paradoxically, polarimetric although being a mature technique in biophotonics, is not so commonly used botany. Importantly, only specific observables, as birefringence or dichroism, have some presence botany studies, and other relevant metrics, those based on depolarization, are...
Abstract The last hundred years have seen the introduction of many sources artificial noise in sea environment which shown to negatively affect marine organisms. Little attention has been devoted how much this could sessile Here, we report morphological and ultrastructural changes seagrass, after exposure sounds a controlled environment. These results are new aquatic plants pathology. Low-frequency produced alterations Posidonia oceanica root rhizome statocysts, sense gravity process sound...
Traditionally, the internal morphology of crustacean larvae has been studied using destructive techniques such as dissection and microscopy. The present study combines advances in micro-computed tomography (micro-CT) histology to decapod larvae, common spider crab (Maja brachydactyla Balss, 1922) a model resolving individual limitations these techniques. synergy micro-CT allows organs be easily identified, revealing simultaneously gross (shape, size, location) histological organization...
The smooth clam Callista chione is an Atlantic-Mediterranean species that commercially exploited in several European countries. Several aspects of its reproduction were studied a coastal location the northwestern Mediterranean as tool for sustainable fisheries management. Gonadal development was classified into 6 different stages, ranging from immature to degradation remaining sexual structures. Results showed C. able reproduce throughout year but main spawning period occurred spring. First...
We describe sperm ultrastructure and acrosome differentiation during spermiogenesis in Crassostrea gigas (Mollusca Bivalvia). The cell is a uniflagellated of the primitive type. head region contains rounded or conical nucleus surmounted by small acrosome. This organelle consists membrane-bound acrosomal granule, contents which have homogeneous density, except anterior region, positive for PTA. also surrounds perforatorium, includes oriented fibrillar elements: this axial body. middle piece...
Abstract The star‐like spermatozoon of Astacus astacus consists a spheroidal central body around which various prolongations same, denominated spines, are arranged. In the interior gamete following parts may be distinguished: (1) acrosomic region, formed by complex vesicle, or thick‐walled, helmetshaped body, whose opening is orientated towards nuclear region. vesicle different structures can appreciated. (2) large cupuliform nucleus limited double membrane. nucleoplasm numerous bundles...
