The moss genus Rhynchostegiella (Helicodontioideae, Brachytheciaceae) has long served as a convenient repository for small brachythecioid pleurocarps. Its circumscription is revised in the context of a chloroplast phylogeny of the Helicodontioideae employing trnL-trnF, atpB-rbcL, psbT-psbH, and psbA-trnH sequence data. The analysis resolves with full posterior probabilities a core Rhynchostegiella clade of eight species. Rhynchostegiella pumila and R. duriaei are both resolved outside that clade and accommodated in their own genera, Microeurhynchium gen. nov. and Pseudorhynchostegiella gen. nov., respectively. Rhynchostegiella leptoneura is sister to Aerolindigia capillacea and R. papuensis is closely related to Eurhynchiella zeyheri. One of the reasons why these unrelated species, together with other taxa, were traditionally included within Rhynchostegiella, is that the genus is morphologically poorly defined by only a single synapomorphic change followed by reversals in half of the species. The Madeiran endemic Brachythecium percurrens is resolved as sister to all the other genera of the Helicodontioideae and is transferred into a new monotypic genus, Hedenasiastrum gen. nov. [less ▲]

The Macaronesian endemic flora has traditionally been interpreted as a relict of a subtropical element that spanned across Europe in the Tertiary. This hypothesis is revisited in the moss subfamily Helicodontioideae based on molecular divergence estimates derived from two independent calibration techniques either employing fossil evidence or using an Monte Carlo Markov Chain (MCMC) to sample absolute rates of nucleotide substitution from a prior distribution encompassing a wide range of rates documented across land plants. Both analyses suggest that the monotypic Madeiran endemic genus Hedenasiastrum diverged of other Helicodontioideae about 40 million years, that is, well before Macaronesian archipelagos actually emerged, in agreement with the relict hypothesis. Hedenasiastrum is characterized by a plesiomorphic morphology, which is suggestive of a complete morphological stasis over 40 million years. Macaronesian endemic Rhynchostegiella species, whose polyphyletic origin involves multiple colonization events, evolved much more recently, and yet accumulated many more morphological novelties than H. percurrens. The Macaronesian moss flora thus appears as a complex mix of ancient relicts and more recently dispersed, fast-evolving taxa. [less ▲]

Dispersal ability is a factor of prime importance to explain biotic distributions. Yet, it is extremely difficult to measure directly. In this study, we take advantage of the natural experimental design of slag heap colonization in Belgium to document the timing and range of dispersal of bryophytes at the landscape scale. On the basis of a species atlas with a 4 × 4 km grid, the minimum distance separating species found on 52 slag heaps from potential source populations was determined. Minimum dispersal rates were inferred by coupling the information on minimum distance between slag heap and source populations with time since colonization. The number of species per slag heap is significantly correlated with time since colonization and area size. The frequency distribution of the longest dispersal events is highly skewed, with 44% of the species recruited within the nearest 6 km. In the remaining 56% of the species, recruitments from source populations located within a range of at least 6–86 km occurred within a period of less than 50 years. The majority of the species that are not recruited within the nearest vicinity of the slag heaps, including rare species at the regional scale, occur on slag heaps that have been colonized for 25–50 years. Most recently colonized slag heaps are indeed characterized by 'fugitive', weedy species, whereas slag heaps that have been colonized for > 50 years tend to accumulate perennial species with a 'stayer' life strategy. These observations suggest that rare species may display the dispersal ability to travel across the landscape, but are subsequently limited by their ability to establish a viable community because of more competitive neighbours. Rare species therefore tend to accumulate at intermediate colonization stages, which represent a trade-off between an increasing probability of colonization with time and a decreasing probability of establishment due to competition.

The co-evolution between hosts and parasites has long been recognized as a fundamental driver of macro-evolutionary patterns of diversification. The effect of co-differentiation on parasite diversification is, however, often confounded by underlying geographic patterns of host distribution. In order to disentangle the confounding effects of allopatric versus host speciation, the mitochondrial cytochrome b (cyt b) gene was sequenced in seventy individuals of the parasitic nematode genus Heligmosomoides sampled in the six Apodemus mice species common in the western Palearctic region. The nuclear internal transcribed spacers (ITS) 1 and 2 were also sequenced in fifteen parasites to confirm the mitochondrial data. All lineages differentiated according to a geographic pattern and independently from the sampled host species. This suggests that host speciation did not involve concurrent parasite speciation. However, the geographic distribution range of some parasite lineages mirrors that of A. sylvaticus lineages in SW Europe, and that of A. flavicollis lineages in the Balkans and in the Middle East. Thus, regional co-differentiation likely occurred between the parasite and the two sister Apodemus hosts in different parts of their distribution range. We suggest that differences in regional abundances of A. sylvaticus and A. flavicollis are responsible for generating this pattern of regional co-differentiation. This study highlights the importance of integrating both geography and biogeographic information from potential hosts to better understand their parasite phylogeography. [less ▲]

Based on a thorough review of the literature as well as floristic surveys undertaken over 20 years, a checklist of the bryophytes of Corsica, a mountainous western Mediterranean island, is presented. The occurrence of 17 liverwort and 44 moss species is documented for the first time from Corsica. As a result, the Corsican bryoflora includes 540 species: 148 liverworts, three hornworts and 389 mosses. Among the species reported, seven liverwort and 17 moss species are red-listed in Europe. By contrast with angiosperms, no bryophyte is endemic to the island based on traditional, phenetic species concepts. The number of new species reported here indicates that Corsica is exceedingly under-recorded bryologically. A better knowledge of the distribution, frequency and ecology of bryophyte species on the island is thus an absolute prerequisite in order to propose appropriate conservation measures in this Mediterranean environment that is, at least locally, severely threatened.
