Onisimus turgidus (Sars, 1879) (Amphipoda, Uristidae), an overlooked amphipod from sea anemones in Northern Norway

European Journal of Taxonomy, 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 material belongs to O ...

Sibling Species in Artemia (Crustacea:Branchiopoda) [PDF]

Evolution, 1968
The species Artemia salina (L.) is composed of a group of differentiated units, which cannot interbreed because of differences in the manner of reproduction (Artom, 1931; Barigozzi, 1944, 1946, 1957). Artemia salina has, therefore, been termed by Artom "specie collettiva" also taking into consideration the different ploidy degrees.

Fluorescent Pigment Distinguishes Between Sibling Snail Species [PDF]

Zoological Science, 2008
Traditional taxonomy of shell-bearing molluscs does not generally use soft-body coloration. However, the land snails Bradybaena pellucida and B. similaris have been distinguished only on the basis of the color of the soft-body visible through the shell. Thus, the taxonomic status of the two species has traditionally been questionable.

Higher gregarine parasitism often in sibling species of host damselflies with smaller geographical distributions [PDF]

, 2012
1. This study investigated inter-specific variation in parasitism by gregarines (Eugregarinorida: Actinocephalidae), among sibling species of damselflies (Odonata: Zygoptera), in relation to relative size of geographical ranges of host species.

‘O sibling, where art thou?’ – a review of avian sibling recognition with respect to the mammalian literature [PDF]

, 2004
Avian literature on sibling recognition is rare compared to that developed by mammalian researchers. We compare avian and mammalian research on sibling recognition to identify why avian work is rare, how approaches differ and what avian and mammalian ...

Modified PCR-based assay for the differentiation of members of Anopheles fluviatilis complex in consequence of the discovery of a new cryptic species (species V)

Malaria Journal, 2020
Background Anopheles fluviatilis is a species-complex comprising of four cryptic species provisionally designated as species S, T, U and V. Earlier, a 28S-rDNA based allele-specific polymerase chain reaction (ASPCR) assay was developed for the ...

Polyandrous females avoid costs of inbreeding [PDF]

, 2002
Why do females typically mate with more than one male? Female mating patterns have broad implications for sexual selection, speciation and conflicts of interest between the sexes, and yet they are poorly understood. Matings inevitably have costs, and for
