Il contributo del letame alla nematofauna
2023
Gli effetti benefici del letame sul suolo e sulla resa delle colture sono stati ampiamente dimostrati grazie al suo alto contenuto di sostanza organica. Inoltre, il letame può aumentare l'attività biologica e la diversità degli organismi del suolo, il che a sua volta può portare a ridurre al minimo i danni alle colture da agenti patogeni presenti nel suolo. Inoltre numerose sono le segnalazioni sul successo dell'applicazione del letame al fine di ridurre i nematodi delle lesioni radicali in diversi sistemi colturali. Tuttavia, al meglio delle nostre conoscenze ci sono pochi studi sulla caratterizzazione delle comunità di nematodi su letame maturo. E' stato quindi intrapreso uno studio per v…
Shelled-Molluscs Fauna at Abrolhos Bank (Brazil): Assessment of Both Total Species Richness and the Completed Distribution of Species Frequencies by …
2020
Numerous anthropogenic threats to the exceptionally rich coral-reef ecosystem at Abrolhos Bank (Brazil) arguably require implementing drastic conservation policy and meanwhile, urge for the prior detailed assessment of species richness and the species distribution across the Bank. Due to their unavoidable incompleteness, the already implemented “Rapid Assessment Surveys” at Abrolhos Bank deserve being completed, at least numerically, by implementing an appropriate extrapolation procedure, to avoid serious bias precisely due to ignoring both the number and the frequency distribution of those species still remaining undetected after Rapid Assessment Surveys. Complying with this concern, I rep…
Position of the palaeontological site Aven I des Abîmes de La Fage, at Noailles (Corrèze, France), in the European Pleistocene chronology
2003
Mourer-Chauvire, C., Philippe, M., Quinif, Y., Chaline, J., Debard, E., Guerin, C. & Hugueney, M. 2003 (September): Position of the palaeontological site Aven I des Abimes de La Fage, at Noailles (Correze, France), in the European Pleistocene chronology. Boreas, Vol. 32, pp. 521–531. Oslo. ISSN 0300–9483. The palaeontological locality of Aven I des Abimes de La Fage, at Noailles, Correze, France, is a limestone swallow hole filling which includes a rich fauna of micro- and macromammals, and one of the most complete Pleistocene avifaunas in the Palearctic. According to the mammal fauna and to the sedimentological study, the filling was previously assigned to the penultimate, Saalian, glaciat…
The invasive seaweed Asparagopsis taxiformis erodes the habitat structure and biodiversity of native algal forests in the Mediterranean Sea
2021
Abstract Invasive seaweeds are listed among the most relevant threats to marine ecosystems worldwide. Biodiversity hotspots, such as the Mediterranean Sea, are facing multiple invasions and are expected to be severely affected by the introduction of new non-native seaweeds in the near future. In this study, we evaluated the consequences of the shift from the native Ericaria brachycarpa to the invasive Asparagopsis taxiformis habitat on the shallow rocky shores of Favignana Island (Egadi Islands, MPA, Sicily, Italy). We compared algal biomass and species composition and structure of the associated epifaunal assemblages in homogenous and mixed stands of E. brachycarpa and A. taxiformis. The r…
Caunu (Martes spp.) barošanās paradumu un citu faktoru ietekme uz helmintofaunu un to raksturojošajiem parametriem Latvijā un Lietuvā
2016
Caunas ir savvaļas rezervuāri zoonotiskām un veterināri nozīmīgām parazītu sugām, barošanās paradumu izpēte sniedz informāciju par iespējamiem parazītu invadēšanās ceļiem. Materiāli pētījumam ievākti Latvijas un Lietuvas reģionos laikaposmā no oktobra līdz aprīlim. Lai veiktu barības analīzi, izmeklēti 144 caunu kuņģi. Konstatētie barības objekti iedalīti 14 lielās kategorijās, zīdītāju taksoni noteikti pēc akotmatu struktūras. Kursa darba ietvaros 150 caunas helmintofaunas noteikšanai izmeklētas ar Skrjabina pilnās helmintoloģiskās sekcijas metodi. Meža caunas galvenie barības objekti pēc patērētās biomasas ir grauzēji (37,6%), putni (29,3%) un augi (17,7%) un attiecīgi sastāda arī lielāko…
Rabbit: More than the Magdalenian main dish in the Iberian Mediterranean region. New data from Cova de les Cendres (Alicante, Spain)
2020
Abstract In the Mediterranean Iberian region, rabbit has an important role in the human diet, mainly during the Final Upper Palaeolithic. The archaeological and experimental works about rabbit processing and consumption from the last years provide a wide and relevant framework. The site of Cova de les Cendres (Alicante, Spain) has a relevant role in the knowledge of the Iberian Upper Palaeolithic human subsistence, and offer a wide chronological sequence. The Magdalenian levels of Cendres provide a well-preserve archaeological assemblage of rabbit remains (ca. 90% of the total fauna) to study the human behaviour. The results show subsistence activities focus not only on meat and marrow imme…
Pots, plants and animals: Broad-spectrum subsistence strategies in the Early Neolithic of the Moroccan Rif region
2019
Abstract The transition from hunter-gathering to food-producing societies in the Mediterranean zone of north Africa was complex and variable, likely influenced by local ecological conditions as well as the socio-economic origins of the population. The adoption of domestic plants and animals was piecemeal, with hunting and gathering continuing as an important part of local subsistence strategies. Here, we investigate the timing and extent of the adoption of agricultural practices, namely herding and cultivation, in three diverse coastal and inland Early Neolithic sites in the Mediterranean Maghreb region, namely Ifri Oudadane, Ifri n’Etsedda and Hassi Ouenzga. Results from absorbed lipid res…
New records of amphipod crustaceans along the Israeli Mediterranean coast, including a rare Mediterranean endemic species, Maera schieckei Karaman & …
2020
A survey has been carried out at four Israeli rocky sites to evaluate the diversity of the amphipod fauna on various hard substrates, still scarcely monitored, as potential pabulum for amphipod crustacean species. A survey of shallow rocky reefs along the Mediterranean coast of Israel recovered 28 species and integrated the Amphipoda checklist for the country ofIsrael with 12 newly-recorded species. Such renewed national list includes Maera schieckei Karaman & Ruffo, 1971, a rare species endemic to the Mediterranean Sea, recorded here for the first time from the southern Levant Basin. The species, described from specimens collected in the Tyrrhenian Sea in 1970, has been only record…
The Balearic toad (Bufo viridis balearicus (BOETTGER, 1881)), human bronze age culture, and Mediterranean biogeography
1981
Abstract Microcomplement fixation analysis of albumin relationship shows that the Balearic green toad (Bufo viridis balearicus) is not an original, autochthonous member of the basically Miocene fauna of these western Mediterranean islands, but a quite recent newcomer. The plasma protein pattern clearly points to its close populational relationship to the Tyrrhenian islands' conspecifics. The male and female release vocalization shows the same, and this is in accordance with the external morphology too. There has been no possibility for toads to reach the Balearic Islands in Pleistocene or Holocene via land bridges, nor are they candidates for any sea drifting. Anthropogenic introduction mu…
Presence of pharmaceuticals and heavy metals in the waters of a Mediterranean coastal wetland: Potential interactions and the influence of the enviro…
2015
The occurrence of 17 relevant pharmaceuticals and 7 heavy metals in the waters of the Pego-Oliva Marsh Natural Park (Valencia Community, Spain) were monitored. Thirty four zones (including the lagoon and the most important irrigation channels), covering the main land uses and water sources, were selected for sampling. Thirty three of them were contaminated with at least one pharmaceutical. Ibuprofen and codeine were the pharmaceuticals more frequently detected, in concentrations between 4.8 and 1.2 ng/L and a maximum of 59 ng/L and 63 ng/L, respectively.Regarding metals, Zn showed values under the detection limit in all the samples, while Cd, Co, Cr, Cu, Ni and Pb were detected at concentra…
