      The first typification of Lepra Scop. by Pertusaria discoidea (Pers.) Malme (= Lepra albescens (Hudson) Hafellner), made in the Paris Code (1956), is shown to be correct after studies of the original material in the Micheli ...
    • Onisimus turgidus (Sars, 1879) (Amphipoda, Uristidae), an overlooked amphipod from sea anemones in Northern Norway 

      Vader, Wim; Johnsen, Jan Roger; Tandberg, Anne Helene S. (Journal article; Peer reviewed, 2020)
      Two Norwegian uristid amphipods, obligate associates of sea anemones, have for a long time been confused sub nomine Onisimus normani Sars, 1890. In reality this species only occurs in south Norway, while the north-Norwegian ...

      The dominance of sex in Metazoa is enigmatic. Sexual species allocate resources to the production of males, while potentially facing negative effects such as the loss of well‐adapted genotypes due to recombination, and ...
    • Patterns of coevolution of ambrosia beetle mycangia and the Ceratocystidaceae, with five new fungal genera and seven new species 

      Mayers, CG; Harrington, TC; Masuya, H; Mcnew, DL; Jordal, Bjarte Henry; Shih, H-H; Roets, F; Kietzka, GJ (Peer reviewed; Journal article, 2020)
      Ambrosia beetles farm specialised fungi in sapwood tunnels and use pocket-like organs called mycangia to carry propagules of the fungal cultivars. Ambrosia fungi selectively grow in mycangia, which is central to the ...
    • Patterns of diversification amongst tropical regions compared: a case study in Sapotaceae 

      Armstrong, Kate E.; Stone, Graham N.; Nicholls, James A.; Valderrama Escallon, Eugenio; Anderberg, Arne A.; Smedmark, Jenny; Gautier, Laurent; Naciri, Yamama; Milne, Richard; Richardson, James E. (Peer reviewed; Journal article, 2014-12-03)
      Species diversity is unequally distributed across the globe, with the greatest concentration occurring in the tropics. Even within the tropics, there are significant differences in the numbers of taxa found in each continental ...
    • Phylogenetic conservatism and biogeographic affinity influence woody plant species richness–climate relationships in eastern Eurasia 

      Su, Xiangyan; Shrestha, Nawal; Xu, Xiaoting; Sandanov, Denis; Wang, Qinggang; Wang, Siyang; Dimitrov, Dimitar; Wang, Zhiheng (Journal article; Peer reviewed, 2020)
      Mechanisms underlying species richness patterns remain a central yet controversial issue in biology. Climate has been regarded as a major determinant of species richness. However, the relative influences of different ...
    • The phylogenetic systematics of Spilomelinae and Pyraustinae (Lepidoptera: Pyraloidea: Crambidae) inferred from DNA and morphology 

      Mally, Richard; Hayden, James E.; Neinhuis, Christoph; Jordal, Bjarte Henry; Nuss, Matthias (Peer reviewed; Journal article, 2019)
      Spilomelinae and Pyraustinae form a species-rich monophylum of Crambidae (snout moths). Morphological distinction of the two groups has been difficult in the past, and the morphologically heterogenous Spilomelinae has not ...
