Tape lures swell bycatch on a Mediterranean island harbouring illegal bird trapping
<p>Mediterranean islands provide shelter and sustenance for millions of migrating birds each year. Humans have historically exploited bird migration through hunting. In Cyprus, trapping birds during their migratory peak is considered a tradition, but has long been against the law. Illegal bird trapping is lucrative, however, with trappers using tape lures that broadcast birdsong to increase capture rates. It results in the slaughter of millions of birds each year. Yet, scientific studies quantifying capture rates of target and nontarget species using methods employed by trappers are lacking. Here, we show using playback experiments that tape lures lead to an order of magnitude greater capture rates of target species, but also significantly increase bycatch, which may include species of conservation concern. Conservation efforts focusing on minimizing illegal bird killing should also consider tape lures and their contribution to the overall impact of trapping on avian populations.</p>

Shell length 16.7 mm; scale bar 2.0 mm. Not shown are a thin encrustation over most of the first whorl and minimal fractures on the peristome. 2. Protoconch sculpture of Balearena gymnesica.

FIGURE 4–5. 4 in A new genus and species of Enidae (Gastopoda: Pulmonata) from the Quaternary of the Balearic Islands (Western Mediterranean)
FIGURE 4–5. 4. Outlines of Mastus pupa (thick dark line, solid circles) and Balearena gymnesica (thin pale line, empty circles) in standard (front) orientation, scaled to same length and superimposed. The landmarks selected for the geometric morphometric analysis are indicated by circles, arrows showing the relative displacement among the two shapes. 5. Principal component analysis of truss distances defined by the landmarks shown in Fig. 4, measured on the specimens shown in Fig. 3. The first principal component (PCI) accounts for 54.95 % of total variance, and bears loadings mostly along the axis defined by shell length; the second principal component (PCII) explains 44.97 % of total variance, and its loadings are mostly along the axis perpendicular to shell length. Both components reflect changes with size, larger shells scoring higher on PCI and lower on PCII.

Pleistocene range expansion throughout the Mediterranean and back-colonization from the Canary Islands in the legume Bituminaria bituminosa
<p><strong>Aim:</strong> Species with widespread distributions offer excellent opportunities for investigating recent biogeographical patterns across broad scales. Here, we tested the hypothesis that, due to its intermediate geographical location, NW Africa is pivotal in explaining the phylogeographical patterns of taxa with Mediterranean-Macaronesian distributions using a legume species with short generation times.</p> <p><strong>Region:</strong> Mediterranean, with a focus on NW Africa and the Canary Islands</p> <p><strong>Taxon:</strong> Pitch trefoil ( <em>Bituminaria bituminosa</em>)</p> <p><strong>Methods:</strong> We generated genetic data and performed phylogeographical and demographic analyses at two geographical scales: Mediterranean Basin (MB), using plastid sequences (115 individuals), and Macaronesia, using plastid sequences (182 individuals) and 10 nuclear microsatellite loci (220 individuals). We also performed a literature survey focusing on phylogeographical studies of other circum-Mediterranean taxa.</p> <p><strong>Results:</strong> North-west Africa was identified as a center of genetic diversity (19 out of 38 haplotypes) and demographic expansion of <em>B. bituminosa</em> in the MB during the Pleistocene. Our literature review revealed two main phylogeographical patterns in widespread species: pre-Mediterranean evergreen sclerophylls vs. Pleistocene facultative-deciduous (including <em>Bituminaria</em>) taxa, but on average both functional groups show a similar, large genetic diversity (c. 40% of haplotypes) in NW Africa. At the Macaronesian scale, we found that Canarian <em>Bituminaria </em>is composed of two genetic sublineages that coexist and hybridize on the central islands and in the mainland Macaronesian enclave (Anti-Atlas region). Demographic analyses rejected the progression rule as the model of island colonization, but strongly suggested that Anti-Atlas populations are the result of back-colonization from the easternmost islands before the Last Glacial Maximum (LGM).</p> <p><strong>Conclusions: </strong><em>Bituminaria</em> displays a pattern of Quaternary eastward expansion in the MB that appears to be paralleled by several members of its functional plant group. Thus, our study reveals a previously undescribed dual role of NW Africa in plant biogeography, acting both as a source of species expansion to the rest of the MB and a LGM refugium of plant populations with a Macaronesian island origin.</p>

Original distribution after last Ice Age restricted to Iberian Peninsula, W France, and N Africa. Ancient introductions of the nominate subspecies probably during the Ro- man period have spread it throughout Europe, and now it is present in most of W, C & E Europe and the Mediterranean and Macaronesian Is (these mostly old introductions are also shaded on the map). During the 20" century it has been released into the steppes of the Black Sea in Ukraine and Russia (N Caucasus); introduced into Australia in 1788 and again in 1859 where it is now widespread; it is found on many Pacific Is, islands off the coast of South Africa and Namibia, and in New Zealand; successfully introduced only since 1936 into South America, nowadays with a limited range in Chile, Argentina, and Falkland Is, it is also present in the Caribbean Is (all these modern introductions not shaded in the map).
