Abstract
Understanding the genetic diversity and evolutionary history of species is crucial for their conservation and management. In this study, we investigated the genetic diversity and phylogenetic relationships among Eubranchipus species occurring in Japan. Phylogenetic analyses revealed that nuclear and mitochondrial data yield incompatible results. In E. uchidai, nuclear data support the monophyly of the Shimokita area, while mitochondrial data indicate a clustering of Higashidori2 individuals with Hokkaido (Ishikari and Wakkanai) E. uchidai. Similar incongruences were observed in E. hatanakai, where nuclear data favor the monophyly of the Chokai area, while mitochondrial data cluster some Chokai pool 3 individuals with Aizu individuals. These incompatibilities might be caused by mitochondrial gene flow. The findings emphasize the importance of considering both nuclear and mitochondrial data during phylogenetic studies and provide valuable insights into the complex dynamics of migration and genetic exchange in Eubranchipus species.

Abstract
Environmental change jeopardizes the survival of species from variable environments by making the occurrence of favorable conditions less predictable. For organisms with long-lived propagules (e.g., spores, eggs, or seeds), the theory of diversified bet hedging (DBH) predicts that delayed hatching over different growing seasons can help populations avoid extinction. Empirical observations in different organisms are consistent with DBH, but integrated tests that simultaneously validate the main theoretical assumptions and predictions are lacking. In this study, we combine field and multi-generational lab experiments to provide a complete test of DBH. Consistent with DBH predictions, resting egg clutches of the fairy shrimp Branchipodopsis wolfi, which inhabits rain-fed temporary rock pool environments with unpredictable inundations, hatched partially over a succession of inundations with identical hatching cues. Bet hedging was more common in populations from more unpredictable habitats where hatching fractions were lower. This differentiation in hatching strategies was preserved after two generations under common garden conditions, which implies intrinsic (epi-)genetic control of hatching. Finally, a demographic model confirmed that lower hatching fractions increase long-term population growth in unpredictable habitats. With this paper we propose a method to calculate probabilities of successful recruitment for organisms that use imperfect cues and show that this drives selection for variation in life history strategies as part of a DBH strategy.

Abstract
Abstract
Granite and/or gneiss inselbergs are excellent examples of geomorphologically stable island habitats, considered as old, climatically buffered, infertile landscapes (OCBILs). However, unlike oceanic islands, their underlying drivers of diversity patterns remain to be investigated. Here, we studied 24 inselbergs in south-eastern Brazil, aiming to understand the role of landscape variables and environmental conditions in the assembly of the characteristic extremophilic mat vegetation communities. We found that beta diversity was largely explained by climatic variables, whereas species richness did not vary among inselbergs. Classic determinants of the diversity of island communities do not generally seem to apply to these plant assemblages. Overall, these communities change along a coast-to-inland gradient that captures increased seasonality with a replacement of more hydrophilic taxa by more drought-tolerant taxa. Changes in species composition in space involved strong species replacement, with several widespread genera locally represented on distinct inselbergs by different narrowly distributed species. Despite the deterministic sorting of taxa based on climatic conditions, a substantial fraction of the beta diversity remained unexplained. This underlines the importance of historical processes, which are easier to notice in stable OCBIL regions, such as range expansion, local extinction, dispersal constraints and allopatric speciation.

Abstract
While separated by large expanses of dry terrain unsuitable for aquatic biota, aridland waters possess high biodiversity. How aquatic micrometazoans disperse to, and colonize, these isolated ephemeral habitats are not well understood. We used a multi-faceted approach including wind tunnel and rehydration experiments, and next-generation sequencing to assess potential movement of diapausing propagules of aquatic invertebrates by anemochory across regional scales (102-105 km). Wind tunnel experiments using dry playa sediments with added micrometazoan propagules demonstrated that after entrainment by saltation and downwind transport were subsequently recoverable as viable animals when rehydrated. Further, rehydration of fallen natural dust yielded micrometazoans, including rotifers, gastrotrichs, microcrustaceans, and nematodes. Using conserved DNA primers, we identified >3,300 eukaryotic Operational Taxonomic Units (excluding fungi) in the dust including some taxa found in rehydration experiments. Thus, we provide strong evidence that anemochory can disperse micrometazoans among isolated, ephemeral ecosystems in North American deserts and likely elsewhere.

Abstract
Tadpole shrimp (Crustacea, Notostraca) are iconic inhabitants of temporary aquatic habitats worldwide. Often cited as prime examples of evolutionary stasis, surviving representatives closely resemble fossils older than 200 mya, suggestive of an ancient origin. Despite significant interest in the group as 'living fossils' the taxonomy of surviving taxa is still under debate and both the phylogenetic relationships among different lineages and the timing of diversification remain unclear. We constructed a molecular phylogeny of the Notostraca using model based phylogenetic methods. Our analyses supported the monophyly of the two genera Triops and Lepidurus, although for Triops support was weak. Results also revealed high levels of cryptic diversity as well as a peculiar biogeographic link between Australia and North America presumably mediated by historic long distance dispersal. We concluded that, although some present day tadpole shrimp species closely resemble fossil specimens as old as 250 mya, no molecular support was found for an ancient (pre) Mesozoic radiation. Instead, living tadpole shrimp are most likely the result of a relatively recent radiation in the Cenozoic era and close resemblances between recent and fossil taxa are probably the result of the highly conserved general morphology in this group and of homoplasy.
