- Fungal metabarcoding of substrates such as soil, wood, and water is uncovering an unprecedented number of fungal species that do not seem to produce tangible morphological structures and that defy our best attempts at cultivation, thus falling outside the scope of the International Code of Nomenclature for algae, fungi, and plants. The present study uses the new, ninth release of the species hypotheses of the UNITE database to show that species discovery through environmental sequencing vastly outpaces traditional, Sanger sequencing-based efforts in a strongly increasing trend over the last five years. Our findings chal-lenge the present stance of some in the mycological community - that the current situation is satisfactory and that no change is needed to "the code" - and suggest that we should be discussing not whether to allow DNA-based descriptions (typifications) of species and by extension higher ranks of fungi, but what the precise requirements for such DNA-based typifications should be. We submit a tentative list of such criteria for further discussion. The present authors hope for a revitalized and deepened discussion on DNA-based typification, because to us it seems harmful and counter-productive to intentionally deny the overwhelming majority of extant fungi a formal standing under the International Code of Nomenclature for algae, fungi, and plants.

- QuestionWhat changes in character and extent of land use have occurred during the last 200yr in the Biaowiea Primeval Forest (BPF)? Are the landscape transformations described from the multi-temporal analysis of historical maps coherent with vegetation changes expressed by the previous palynological analyses?LocationBiaowiea Primeval Forest, PolishBelarusian border. MethodsWe used five historical maps (from 1793 to 1936) and one digital land-use map (19992000) to quantify the landscape changes. Land-use types according to historical maps were digitized and georeferenced. The maps were then used for both comparing the extent of cover types in each time step and analysing the nature of change through transition matrices. The sequence of changes concerning the proportion of land-use types was then compared with classes of pollen, which were assumed to represent corresponding vegetation types. ResultsMost of the area (>70%) has been continuously covered with forest. In the period between 1793 and 1830, the forest declined, being the main donor to agricultural land and villages. In the 20th century, the trend was reversed. We found a significant correlation between the percentage of the main vegetation types derived from historical maps and the corresponding vegetation types, as indicated by pollen, with a mean time lag of 20yr. ConclusionThe BPF landscape has been quite stable throughout the last 200yr, mainly due to the high continuity of forest cover. The results obtained from landscape analysis based on maps are coherent with pollen data collected in the same area.

Taxonomy and philosophy of names

- Although naming biological clades is a major activity in taxonomy, little attention has been paid to what these names actually refer to. In philosophy, definite descriptions have long been considered equivalent to the meaning of names and biological taxonomy is a scientific application of these ideas. One problem with definite descriptions as the meanings of names is that the name will refer to whatever fits the description rather than the intended individual (clade). Recent proposals for explicit phylogenetic definitions of clade names suffer from similar problems and we argue that clade names cannot be defined since they lack intension. Furthermore we stress the importance of "tree-thinking" for phylogenetic reference to work properly.

- “Smaller human populations are neither a necessary nor sufficient condition for biodiversity conservation,” according to Alice Hughes and colleagues. We agree that reducing human numbers is not sufficient for preserving biodiversity; whether it’s necessary depends on how high we set the bar for successful conservation. If we hope to preserve robust populations of most of the world’s remaining wild species and their habitats, the evidence suggests human populations will have to be considerably reduced.

Predicting island beetle faunas by their climate ranges : the tabula rasa/refugia theory in the North Atlantic
- 2015

- Aim: This paper addresses two opposing theories put forward for the origins of the beetle fauna of the North Atlantic islands. The first is that the biota of the isolated oceanic islands of the Faroes, Iceland and Greenland immigrated across a Palaeogene–Neogene land bridge from Europe, and survived Pleistocene glaciations in ameliorated refugia. The second argues for a tabula rasa in which the biota of the islands was exterminated during glaciations and is Holocene in origin. The crux of these theories lies in the ability of the flora and fauna to survive in a range of environmental extremes. This paper sets out to assess the viability of the refugia hypothesis using the climatic tolerances of one aspect of the biota: the beetle fauna. Location: The paper focuses on Iceland, the Faroe Islands and Greenland. Methods: The known temperature requirements of the recorded beetle faunas of the North Atlantic islands were compared with published proxy climate reconstructions for successive climate periods since the severing of a North Atlantic land bridge. We used the MCR (mutual climatic range) method available in the open access BugsCEP database software. Results: We show that most of the MCR faunas of the North Atlantic islands could not have survived in situ since the Palaeogene–Neogene, and are likely to have been exterminated by the Pleistocene glaciations. Main conclusions: The discrepancy between the climatic tolerances of the North Atlantic beetle fauna and the estimated climatic regimes since the severing of a land bridge strongly support the tabula rasa theory and suggests that the North Atlantic coleopteran fauna is Holocene in origin.
