Recent evolutionary divergence in a plant ring-species is not accompanied by floral phenology or pollinator shifts [PDF]
Plant Ecology and EvolutionBackground and aims – The study of factors and processes involved in evolutionary divergence can inform how biodiversity is generated and maintained. We evaluate shifts in phenology or in pollination systems as potential barriers to gene exchange and ...

The Formation of the Lesser Antilles [PDF]
Proceedings of the National Academy of Sciences, 1924 The Islands.-The island chain of the Lesser Antilles extends in a curve about 500 miles in length between Porto Rico and Trinidad, and includes 25 larger members with an uncounted number of smaller ones. Most of the islands are of volcanic origin, now in various stages of dissection; but five of the larger islands and two small ones consist wholly of ...

Tracking geothermal anomalies along a crustal fault using (U − Th)∕He apatite thermochronology and rare-earth element (REE) analyses: the example of the Têt fault (Pyrenees, France) [PDF]
Solid Earth, 2020 The Têt fault is a major crustal-scale fault in the eastern Pyrenees (France) along which 29 hot springs emerge, mainly within the footwall damage zone of the fault. In this study, (U-Th)/He apatite (AHe) thermochronology is used in combination with rare-

First 3D reconstruction of a forewing of a fossil Orthoptera: Interpreting the venation pattern in the smallest known cricket with a stridulatory apparatus, †Picogryllus carentonensis (Orthoptera, Grylloidea, Oecanthidae) [PDF]
Fossil RecordFossil insects are valuable indicators of the evolutionary history of the clades to which they belong. According to their state of preservation, fossil insects are often partially described for key morphological characters, such as forewing venation in ...

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora
Biological Reviews, EarlyView.ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.
