Records of free-living flatworms (turbellarians) from Tunisian waters are scattered. Based on new material and published accounts, an annotated checklist of free-living flatworm species from Tunisian waters is provided. A total of 29 species is recorded, including 18 species with new material and 11 species only from literature records. For each species, information on systematics, habitats and distribution is supplied, together with taxonomic or biological remarks. Three species, the acotylean polyclads Cestoplana rubrocinta Lang, 1884 and Comoplana agilis (Lang, 1884) as well as the marine triclad Cercyra hastata Schmidt, 1861 are recorded for the first time in Tunisia. The controversial occurrence of the leptoplanid polyclad Leptoplana tremellaris in the Mediterranean is supported with histological sections and embryological data. The proseriate Monocelis fusca Örsted, 1843 previously reported from Tunisia is considered to be a misidentification.By presenting a checklist of the recorded species, this work summarizes our current knowledge of the turbellarian fauna diversity in Tunisia, providing baseline data for future biogeographical, ecological, behavioral and evolutionary investigations.

The current knowledge of pseudoscorpions in Estonia is summarized, based on specimens preserved in various Estonian collections and new material collected from 1993 to 2015. Altogether 474 studied specimens belonged to 14 species, including nine species recorded from Estonia for the first time. Supplemented by Apocheiridium rossicum, listed by literature data only, the number of known Estonian pseudoscorpions is now set at 15. The findings of Mesochelifer ressli are the northernmost known for the species. Some ecological and phenological observations were made on the most common species, along with notes on the habitat preferences of other species and the use of different trapping methods. The composition of the known Estonian fauna is compared with the published records from the neighbouring countries, revealing a highest similarity to the Finnish fauna.The possible occurrence of other species in Estonia and the latitudinal species diversity gradient in the Eastern Baltic region are shortly discussed.

The Mediterranean specimens of the genus Microporella collected from shallow water habitats during several surveys and cruises undertaken mostly off the Italian coast are revised. As a result of the disentanglement of the M. ciliata complex and the examination of new material, three new species, M. bicollarissp. nov., M. ichnusaesp. nov., and M. pachyspinasp. nov., are described from submarine caves or associated with seagrasses and algae. An additional species Microporella sp. A, distinct by its finely reticulate ascopore, is described but left in open nomenclature owing to the limitations of a single infertile fragment. After examination of all available material, based on their identical zooidal morphology, the genus Diporula is regarded as junior synonym of Microporella and the combination Microporella verrucosa is resurrected as first suggested by Neviani in 1896. Fenestrulina joannae is also reassigned to Microporella. The availability of a large number of colonies of the above-mentioned and other species already well known from the area (i.e., M. appendiculata, M. ciliata, and M. modesta), allowed the assessment of their high intraspecific variability as well as the observation, for the first time, of some morphological characters including ancestrulae, early astogeny, and kenozooids. Finally, M. modesta, in spite of M. ciliata as defined by the neotype selected by Kukliński & Taylor in 2008, appears to be the commonest species in the basin.

The new genus and species, Dicrotrichura tricincta, is described from deep mud (1220 m) in the Ligurian Sea (western Mediterranean). It is the first tantulocaridan not found to be attached to a crustacean host but free living in the sediment. It is assigned to the Deoterthridae on the basis of the absence of a rostrum, the abdominal segmentation and the characteristic cephalic pore pattern. It can be distinguished from all known tantulocaridans in the presence of peculiar, bi-articulated caudal setae and the difference in thoracopodal setation between leg 2 and legs 3–5. Some new structures located on the attachment disc are described for the first time. D. tricincta is the second tantulocaridan to be recorded from the Mediterranean.

Sampling surveys (1976-2013) of soft-bottom communities and some hard bottom communities along the Algerian coast (1,180 km) have allowed the collection of 114 species of crustacean decapods of which of 37 were reported for the first time for the Algerian decapods fauna; for these species additional comments concerning their ecological and geographical patterns are given. The inventory of all benthic and pelagic decapods recorded along the Algerian coast reaches 253 species. Three families on a total of 57 families were highly diversified: Paguridae (17 species), Polybiidae (16 species) and Processidae (13 species). The presence of the 253 recorded species along the Algerian coast has been compared with eight other areas from the Mediterranean Sea. The decapods fauna of the Algerian coast is among the most richest of the Mediterranean Sea and comparable of that of Italy.

Poa maroccana is an annual Mediterranean species, which is recorded for the first time from Sicily and for the whole Italian territory. It usually occurs in synanthopic habitats, represented mainly by urban and suburban roadsides, where it is quite sporadic. Based on current knowledge, it has been hitherto reported only in a few localities of the Mediterranean area, particularly in Morocco, Algeria, Tunisia, Libya, Spain, Portugal, Greece, Turkey, Syria and Crimea. Field observations and herbarium investigations have shown that this species is often mistaken for P. annua, mainly due to its morphological similarities, as well as for the same ecological needs, therefore its real geographical distribution has yet to be verified. Although the two species are both tetraploids (2n = 28), they clearly differ for numerous relevant features concerning the shape and size of ligules, inflorescence, spikelet, glumes, palea, lemma, anthers, lodicules and seed. In order to better clarify the relationships of P. maroccana with P. annua and the other annual species of this genus occurring in the Mediterranean, its carefull a morphological description and iconography is provided, as well as a comparative morphological table of all allied species and also their analytical key for easy identification.

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. It comprises a total of 1191 species, distributed among 3 superclasses, 4 classes, 42 orders, 212 families and 617 genera. If considering only the EEZ and present territorial waters, this list represents an increase of 230 species (27.8%) and of 238 species (29.0%), when compared to the information available in FishBase (2012) and in the last checklist of marine and estuarine fishes of Portugal (1993), respectively. The order Perciformes shows the highest diversity, with 54 families, 162 genera and 299 species. Stomiidae (80 species), Myctophidae (71 species) and Macrouridae (37 species) are the richest families. From the listed species, 734 are present off mainland Portugal, 857 off the Azores and 766 off Madeira. Within the limits of the examined area, three species are reported for the first time in mainland Portugal and twenty-nine records are identified as doubtful. A total of 133 species have been recorded from the extended Portuguese continental shelf (2 off mainland Portugal, 117 off the Azores and 14 off Madeira), two of which are common to the Azores and Madeira extensions. Biogeographically, the Atlantic group is the most important (548 species – 46.01%), followed by the Lusitanian group (256 species – 21.49%), the African group (71 species – 5.96%), the Boreal group (34 species – 2.85%), the Mediterranean group (31 species – 2.60%), the Macaronesian group (21 species – 1.76%), the Atlantic/African group (19 species – 1.60%) and the Mediterranean/African and the Arctic groups, each with only 1 species (0.08%). Regarding the preferences for vertical habitat, the demersal fishes are the most important group (305 species – 25.61%), followed by the mesopelagic group (228 species – 19.14%), the bathypelagic group (164 species – 13.77%), the benthopelagic group (147 species – 12.34%), the bathydemersal group (115 species – 9.66%), the reef-associated group (88 species – 7.39%), the pelagic group (74 species – 6.21%), the epipelagic group (58 species – 4.87%) and 1 species (0.08%) of the benthic group. The oceanic habitat is the best represented group comprising 446 species (37.45%), followed by the shelf group (199 species – 16.71%), the slope group (164 species – 13.77%), the inner shelf group (89 species – 7.47%), the coastal group (70 species – 5.88%), the outer shelf group (29 species – 2.43%) and the oceanic/shelf group (7 species – 0.59%).

Calanoids of the family Diaptomidae are the most widespread copepods in the lentic inland waters of the Palearctic region. In Italy, studies on the family date back to the end of 19th century. Since then, several papers contributed to increasing the knowledge on their presence, distribution, and ecological preferences. Nevertheless, new records for the area and the discovery of putative new species stress that the current knowledge on these inland water crustaceans is still far from being exhaustive. This paper presents an updated and annotated checklist and bibliography of the Diaptomidae of the Italian peninsula and surrounding islands, including Corsica and the Maltese islands, compiled through a critical review of the existing literature and carrying out further field research. The doubtful records reported in the literature are discussed and clarified. The updated checklist includes 30 diaptomid species and subspecies; among them, an alien species and three putative new species pending formal description are reported. About 20% of the observed species are endemic or subendemic to the study area. The faunal provinces ascribed to the Mediterranean limnofaunistic region host the highest species richness and contribute to the checklist with rare species and unique occurrences. The high species richness observed in the Mediterranean area supports the hypothesis of a long-lasting persistence of an ancient and peculiar copepod fauna.

: Melanoma is the most life-threatening and aggressive class of skin malignancies. The incidence of melanoma has steadily increased. Metastatic melanoma is greatly resistant to standard anti-melanomatreatments such as chemotherapy, and 5-year survival rate of cases with melanoma who have metastatic form of disease is less than 10%. The contributing role of apoptosis, angiogenesis and autophagy in the pathophysiology of melanoma has been previously demonstrated. Thus, it is extremely urgent to search for complementary therapeutic approachesthat couldenhance the quality of life of subjects and reduce treatment resistance and adverse effects. Resveratrol, known as a polyphenol component present in grapes and some plants, has anti-cancer properties due to its function as an apoptosis inducer in tumor cells, and anti-angiogenic agent to prevent metastasis. However, more clinical trials should be conducted to prove resveratrol efficacy. : Herein, for first time, we summarize current knowledge of anti-cancerous activities of resveratrol in melanoma.
