ABSTRACT Aim To test whether congeneric species are significantly associated with one another in space, either positively or negatively. Also, to provide a framework for causal investigation of co‐occurrence patterns by parallel comparison interactions geographical and ecological data matrices. Location For the analysis species’ co‐occurrences we used 30 matrices covering wide range taxa areas, while distribution 50 terrestrial isopod on 20 islands 264 sampling stations central Aegean...
Abstract Anatolian mountains have played an important role in speciation and definition of biogeographical subregions been defined as “hotspots” biodiversity. Because its position long palaeogeographic palaeoclimatic history, Anatolia acted the past a bridge or barrier for species' dispersal, providing natural pathways acting vicariant agent, respectively. In this study we investigated phylogeny biogeography small fossorial snake, Typhlops vermicularis , Anatolia, using formalin-preserved...
Flying over the open sea is energetically costly for terrestrial birds. Despite this, over-water journeys of many birds, sometimes hundreds kilometres long, are uncovered by bio-logging technology. To understand how these birds afford their flights sea, we investigated role atmospheric conditions, specifically wind and uplift, in subsidizing flight at a global scale. We first established that ΔT, temperature difference between surface air, meaningful proxy uplift water. Using this proxy,...
Our aim was to investigate species co-occurrence patterns in a large number of published biotic communities, order document what extent associations can be found presence-absence matrices. We also compare and evaluate two metrics that focus on pairs (the ‘natural’ the ‘checkerboard’ metric) using artificial applied many data sets from huge variety insular systems around world. Both reliably recover deviating provide similar, albeit not identical, results. Nevertheless, only few matrices...
Conservation of migratory species faces the challenge understanding ecological requirements individuals living in two geographically separated regions. In some cases, entire population widely distributed congregates at relatively small wintering areas and hence, these become a priority for species' conservation. Satellite telemetry allows fine tracking animal movements distribution those less known, often remote areas. Through integrating satellite GPS data from five populations comprising...
ABSTRACT Aim To investigate the formation of nestedness and species co‐occurrence patterns at local (sampling station), intermediate (island group), archipelago scale. Location The study used data on distribution terrestrial isopods 20 islands central Aegean (Greece). These are assigned to two distinct subgroups (Kyklades Eastern islands). Methods Nestedness Temperature Calculator was obtain values maximally nested matrices, EcoSim7 software a modified version Sanderson (2000 ) method were...
We examined the seasonal patterns of physiology and biochemical composition in rock-dwelling clausiliid land snail Albinaria caerulea relation to its ecology, morphology climatic data.We found that A. displayed significant changes enzyme activity, especially during aestivation.Sugars were catabolized early aestivation, proteins lipids seem be primary metabolic substrates after sugar reserves depleted.Atypical for aestivating snails was accumulation lactate LDH first weeks possibly suggesting...
Drilus beetle larvae (Coleoptera: Elateridae) are specialized predators of land snails. Here, we describe various aspects the predator-prey interactions between multiple species attacking Albinaria (Gastropoda: Clausiliidae) in Greece. We observe that may be facultative or obligate Albinaria-specialists. map geographically varying predation rates Crete, where on average 24% empty shells carry fatal bore holes. also provide first-hand observations and video-footage prey entry exit strategies...
Most insular communities exhibit nestedness, with the species assemblages of more depauperate islands constituting subsets those richer. Several methods for estimation and evaluation nestedness have been developed during last fifteen years. In this paper we use two recent elaborate methods, namely ‘temperature’ method Atmar Patterson ‘departures’ Lomolino, in order to investigate patterns distribution well studied speciose animal groups, terrestrial isopods land snails, Kyklades archipelago...
We studied dispersal patterns in a representative population of the rock-dwelling land snail Albinariacoerulea (Clausiliidae), to obtain direct estimates gene flow and predict spatial scale mode differentiation expansion. recorded estimated per month, at site Vravrona (Attica, Greece), for period equal assumed generation time (2.5 years), distances directions from four remote release stations minimal movements recapture points 200 individually marked specimens. Mean movement were small...
Abstract The genus Dendarus Latr. is distributed throughout the Mediterranean basin with numerous species in Aegean islands. This paper presents a phylogenetic analysis and biogeography of most taxa present area. Phylogenetic two outgroup 25 ingroup based on adult morphology, including 50 characters 119 character states, produced equally parsimonious trees (tree length = 148, C.I. 0.42, R.I. 0.70, R.C. 0.294). These provide strong support for monophyly also define four groups: foraminosus...
Abstract Aim To develop a simple method that (1) combines the notions of biotic elements (groups taxa with ranges significantly more similar to each other than taxa) and areas endemism (AoE, non‐random distributional congruence among taxa), (2) overcomes constraints previously suggested null model‐based cannot deal disjunctions is strictly grid‐dependent. Location We used test data sets from southern Africa Crete. Methods First, we null‐model approach detect pairs species have significant...
Land snails usually exhibit cycles of activity and dormancy (aestivation or hibernation). The transition between these two states is accompanied by a range behavioural physiological responses to ensure their survival under adverse environmental conditions. Furthermore, aestivation plays an important role in shaping species' distribution patterns. We examined the seasonal patterns biochemical tissue composition relation aspects ecology three land snail populations: one mainland insular...
A significant number of studies worldwide have shown that incidental catches (by-catch) seabirds in fishing gear might pose a considerable risk for the conservation their populations. Nevertheless reliable data on by-catch rates European marine ecosystems are patchy and need to be improved. This study constitutes first attempt at evaluation southern Ionian Sea. Data were obtained by distributing specific questionnaire fishers Zakynthos Island. 150 professional (representing 90% local fleet)...
Two slow worm species are distributed at the southernmost part of Balkan Peninsula: Anguis cephallonica , an endemic Peloponnese and islands Zakynthos, Ithaki Kephallonia, A. graeca . Here, we investigate intraspecific genetic diversity from Kephallonia analyse northern Peloponnese, where it is found in sympatry with MtDNA nDNA phylogenetic analyses confirm similarity Peloponnesian Kephallonian populations reveal significant mtDNA variation within it, probably related to occurrence multiple...
Albinaria, despite its restricted geographical distribution, exhibits an extreme degree of differentiation. The use conventional or numerical taxonomy has not facilitated the understanding evolution genus. Twelve populations belonging to four species were studied with a combined approach using mitochondrial DNA (mtDNA) and qualitative morphological data. complete mtDNA genome A. coerulea from Amorgos island was cloned used in restriction site analysis other populations. Maximum parsimony...
