Palaeolimiinological data (diatoms, ostracods, foraminifera, molluscs, aquatic pollen and lithologyj) from a radiocarbon dated sediment core from a saline lake, the Laguna de Medina, provide the first complete record of Holocene lake-level change for southwest Spain for the last c. 9000 cal. years. The lake has always been relatively shallow but has exhibited marked fluctuations in salinity and water depth, especially in the earlier record when oscillationis ctUlminate in maxinmuim lake levels from c. 6960-6680 cal. BP (c. 6070-5830 BP), indicating enhanced early-to mid-Holocene humidity and a mid-Holocene humidity maximuLm. Prolonged shallowing thereafter reflects in par-t increased aridity in the later Holocene. Lake desiccation followed by a c. 800-yr phase (zone 2) of major limnliological change commencing at c. 8000 cal. BP (c. 7200 BP), and a ntimber of other abrupt desiccation events, are also noteworthy. The mid-Holocene maximum is consistent with widespread evidence for high lake levels around 6000 BP, but the underlying climatic mechanisms are tincertaini; there is some evidence it may apply predomiainantly to the westerly (Atlantic) Peninsula, withi earlier maxima in the east. Phases of abrupt limnological change show affinities with African data; as in African lakes, the 'zone 2' phase appears to be a response to global change centred oni c. 8.1-8.2 cal. BP. Other correlations miiade are tenuous, due partly to the lack of preservation in the upper record of some of the proxies used. Other desiccation events currently appear to be of more local significance, reflecting high decadal-to century-scale climatic variability throughout the Holocene.

“…The most important features of Mljet National Park are two lake-like inlets, Malo Jezero and Veliko Jezero (Eng. Small Lake and Great Lake), which are located on the western part of Mljet island and are a natural phenomena of karstic depressions (Wunsam et al, 1999). Malo Jezero is connected with Veliko Jezero through a shallow and narrow channel, which is in turn connected to the surrounding open sea through a somewhat deeper and wider channel.…”

SUMMARY: Although previous studies have noted the presence of the bivalve Pinna nobilis Linnaeus, 1758 in Mljet National Park, there is a lack of basic knowledge of this endangered species. The present study was initiated as part of a long-term investigation of P. nobilis density and growth with the aim of gaining a better understanding of this species' population dynamics, as well as evaluating the efficiency of protection measures of P. nobilis in Mljet National Park. Density, population structure, growth of tagged individuals and epibionts on P. nobilis were studied using SCUBA diving in 1998 and 2000 along four transects in Mljet inlets, Adriatic Sea. The density of P. nobilis ranged from 0.20 ind/m 2 on transect MLJ-9 in Malo Jezero in 1998 to 0.02 ind/m 2 on transect MLJ-5 in Veliko Jezero in 2000. Individuals measured in 1998 were significantly smaller than those measured in 2000. Growth curves were constructed from data collected by tagging and re-measuring 47 individuals. A decrease in density along some of the transects and the disappearance of 24 tagged individuals in 2000 is suggestive of poaching. The results of the present study indicate recovery of the P. nobilis population in Mljet lakes, but also provide evidence for the illegal removal of this protected species.

“…The study only presents preliminary results of diatom analysis, however, and the chronology is uncertain. Apart from a study of Holocene environmental change in Croatian coastal lagoons (Wunsam et al, 1999), other diatom-based study sites have been undertaken on remote mountain lakes. A rigorous multi-proxy study of Late Glacial and Holocene climate, vegetation and palaeolimnological change in southwest Bulgaria (Stefanova et al (2003) confirms the potential of diatoms for elucidating the temporal dynamics of aquatic ecosystems, but most papers focus only on short-term (last ca.…”

“…A range of these species is common in Holocene African lake sediments (e.g. Fontes & Gasse, 1991) and Holocene Dalmatian coastal lagoon sequences (Wunsam et al, 1999), but they are absent both in the Spanish (Reed, 1998) and African (Gasse et al, 1995) modern flora. In MDN, they occur with the ostracod, Cyprideis torosa, which is also now restricted to shallow coastal lagoons in Spain (Reed, unpublished data); the assemblage clearly indicates an ecosystem of permanent, shallow, chloride-dominated waters which has disappeared from inland waters of the region.…”
