Hucho hucho (Linnaeus, 1758): last natural viable population in the Eastern Carpathians - conservation elements

2019

There is great variation in the conservation status of the last habitats with long-term natural viable populations of the salmon species Hucho hucho in Maramureş Mountains Nature Park, Eastern Carpathians (Romania). According to the specific guidelines for Natura 2000, 42.11% are in good conservation status, 31.57% are of average status, and 26.32% are in a partially degraded condition. In this study area, 6 main risk elements were identified related to human impact on the environment: poaching, minor riverbed mor-phodynamic changes, liquid and solid natural flow disruption, habitat fragmentation leading to isolation of fish populations, organic and mining pollution, and destruction of ripa…

Intensive Management and Natural Genetic Variation in Red Deer (Cervus elaphus)

2017

The current magnitude of big-game hunting has outpaced the natural growth of populations, making artificial breeding necessary to rapidly boost hunted populations. In this study, we evaluated if the rapid increase of red deer (Cervus elaphus) abundance, caused by the growing popularity of big-game hunting, has impacted the natural genetic diversity of the species. We compared several genetic diversity metrics between 37 fenced populations subject to intensive management and 21 wild free-ranging populations. We also included a historically protected population from a national park as a baseline for comparisons. Contrary to expectations, our results showed no significant differences in geneti…

L'alimentation carnée à Aventicum/Avenches capitale des Helvètes (Ier s. - IVe s. apr. J.-C.) Suisse, canton de Vaud

2010

This first synthesis concerns the animal bones, discovered since 1975 in Aventicum, the capital of Roman Switzerland. It is supported by the analysis of several residential districts, public sectors and suburbs, which represent five hundred chronological complexes and 74000 animal bones, dated from the Ist, to the IVth Century AD. During these centuries, Aventicum was incorporated to the Roman province of Gallia Belgica, then was raised to the status of a colonia and finally declined with the Empire.The analysis of bones was made to study various mutations which occurred during the occupation of the city. They include an improvement of breeding techniques, a new internal city organisation, …

The classification of submerged vegetation using hyperspectral MIVIS data

2009

The aim of this research is to use hyperspectral MIVIS data to map the Posidonia oceanica prairies in a coastal lagoon (Stagnone di Marsala). It is approximately 12 km long and 2 km wide and is linked to the open sea by two shallow openings. This environment is characterised by prairies of phanerogams, the most common of which is Posidonia oceanica, an ideal habitat for numerous species of fish, molluscs and crustaceans. A knowledge of the distribution of submerged vegetation is useful to monitor the health of the lagoon. In order to classify the MIVIS imagery, the attenuation effects of the water column have been removed from the signal using Lyzenga’s technique. A comparison between class…

Density Decline in a Mediterranean Seahorse Population: Natural Fluctuations or New Emerging Threats?

2021

Illegal wildlife trade is considered one of the most serious threats to biodiversity worldwide, along with habitat loss/degradation and overfishing of wild stocks. Seahorses are considered at high risk as these fish represent an important component of traditional Chinese medicine but are also sold as curios and ornamental fish. On a worldwide level, illegal trade is controlled by numerous laws and regulations, but it seems to continue by assuming more dynamic routes. In the Mediterranean Sea, Hippocampus guttulatus formed one of the largest populations at Mar Piccolo di Taranto in South-Eastern Italy. During the routine monitoring of this population in 2016, a dramatic density decrease was …

An exploratory study to investigate emotion elicited by immersive ambiances

2011

Food behaviour is modulated by the eating situation and environment. In a previous study, we investigated drink choices according to the ambiance by developing an immersive approach based on the concept of “having a drink in a bar”. Two bars (Modern vs. Traditional ambiance) were settled with a few piece of furniture (counter, tables and bar stools) made in raw wood for the Traditional bar and in blue retro-lighted translucent plastic for the Modern bar. A video-clip was projected on one wall: Red moving shapes associated to a “far west” music in the Traditional bar, and Blue moving bubbles associated to an “electro” music in the Modern bar. In each bar, 100 participants were asked which be…

Noyen-sur-Seine (Seine-et-Marne), Nord du Bois du Chêne, Caille-Boton, La Chapotte et Le Haut du Faÿ : phase 2 : rapport de diagnostic

2011

Ce diagnostic se situe sur la commune de Noyen-sur-Seine, sur une carrière d'exploitation de granulats. Il a permis la mise au jour de structures du Campaniforme au Nord-Est du site, de l'étape moyenne du Bronze final (culture Rhin-Suisse-France orientale) et du Hallsatt D2/3-La Tène A. Les structures de la culture RSFO sont en continuité avec celles mises au jour lors du diagnostic sur la parcelle adjacente (Samzun, 2009), et qui ont donné lieu à une fouille durant l'été 2010 (Nallier, à paraître). Les structures du Hallstatt sont apparues au Nord-ouest du décapage.
