Darwin’s closet: the queer sides of The descent of man (1871) Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2021-01-09 Brooks R.
AbstractCharles Darwin’s published and unpublished writings contain a plethora of references to sex variations, including intersexualities (‘hermaphroditism’), transformations of sex and non-heteronormative sexual behaviours. Marking the 150th anniversary of his major sexological work The descent of man, this historical review examines a range of strategies that Darwin deployed in order to accommodate

Sleeping with the enemy: unravelling the symbiotic relationships between the scale worm Neopolynoe chondrocladiae (Annelida: Polynoidae) and its carnivorous sponge hosts Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2020-12-30 Sergi Taboada; Ana Serra Silva; Cristina Díez-Vives; Lenka Neal; Javier Cristobo; Pilar Ríos; Jon Thomassen Hestetun; Brett Clark; Maria Eleonora Rossi; Juan Junoy; Joan Navarro; Ana Riesgo
The North Atlantic deep-water polynoid worm Neopolynoe chondrocladiae is involved in an exceptional symbiotic relationship with two hosts: the carnivorous sponges Chondrocladia robertballardi and Chondrocladia virgata. While this is an obligate symbiotic relationship, its real nature is unclear. We used a multidisciplinary approach to narrow down the type of symbiotic relationship between symbiont

Osteology and phylogeny of small-bodied hadrosauromorphs from an end-Cretaceous marine assemblage Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2020-08-15 Chase Doran Brownstein
The timing of non-avian dinosaur decline is one of the most debated subjects in dinosaur palaeontology. Dinosaur faunas from the last few million years of the Mesozoic appear far less diverse than those from earlier in the Cretaceous, a trend that could suggest non-avian dinosaur extinction occurred gradually. However, the limited nature of the latest Cretaceous dinosaur record outside western North

AbstractThe Australian sugar glider, Petaurus breviceps s.l., is widely distributed across eastern and northern Australia. Examination of historical and contemporary collections of Petaurus specimens and phylogenetic analyses have revealed considerable taxonomic diversity within the genus. We aimed to utilize an integrative taxonomic approach, combining genetic and morphological evidence, to resolve

Near-complete phylogeny of extant Crocodylia (Reptilia) using mitogenome-based data Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2020-07-08 Tao Pan; Jia-Shun Miao; Hua-Bin Zhang; Peng Yan; Ping-Shin Lee; Xin-Yue Jiang; Jia-Hui Ouyang; You-Peng Deng; Bao-Wei Zhang; Xiao-Bing Wu
Species of the order Crocodylia are mostly large, predatory and semi-aquatic reptiles. Crocodylia, the closest living relatives of birds, first appeared in the Late Cretaceous period. In the present study, the complete mitochondrial (mt) genomes of 19 Crocodylia species, including two species (Melanosuchus niger and Caiman yacare) that have not been previously sequenced for mitogenomes, were processed

Integrating morphological and genetic data at different spatial scales in a cosmopolitan marine turtle species: challenges for management and conservation Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2020-07-08 Álvarez-Varas R, Heidemeyer M, Riginos C, et al.
AbstractPatterns of genetic structure in highly mobile marine vertebrates may be accompanied by phenotypic variation. Most studies in marine turtles focused on population genetic structure have been performed at rookeries. We studied whether genetic and morphological variation of the endangered green turtle (Chelonia mydas) is consistent geographically, focusing on foraging grounds. An association

Dromaeosaurid crania demonstrate the progressive loss of facial pneumaticity in coelurosaurian dinosaurs Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2020-07-07 Chase Doran Brownstein
Dinosaurs are notable for their extensive skeletal pneumaticity, a feature that may have helped facilitate the development of various ‘extreme’ body plans in this group. Despite its relevance to understanding the evolution of the avian body plan, this feature has only been described in detail for a few non-avian dinosaurs, and cranial pneumaticity outside the braincase remains poorly documented. I

Cladistic analysis of Ligyra sensu lato (Diptera: Bombyliidae), with description of a new genus Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2020-07-01 Ángela Sabrina Márquez-Acero; Christine L Lambkin; Carlos José Einicker Lamas
Exoprosopini is one of the largest tribes of bee flies (Diptera: Bombyliidae). It is divided into 21 genera of which only Ligyra has a cosmopolitan distribution. The genus Ligyra s.l. has 111 species, 20 of which have been recorded in the New World. A cladistic analysis was implemented with aims to establish the phylogenetic relationships of Ligyra species and to test the monophyly of the genus. A

Tooth-shape adaptations in aglyphous colubrid snakes inferred from three-dimensional geometric morphometrics and finite element analysis Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2020-07-01 Rajabizadeh M, Van Wassenbergh S, Mallet C, et al.
AbstractTo date there are few quantitative studies investigating the evolution of tooth shape and function in aglyphous snakes in relation to diet. A considerable evolutionary decrease in body size is observed in whip snakes of the genus Dolichophis and their sister-group Eirenis. This was coupled with a considerable shift in diet from a regime consisting mainly of prey with endoskeleton to prey bearing

Phoretic copulation in Aculeata (Insecta: Hymenoptera): a review Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2020-06-29 Felipe Vivallo
Phoretic copulation is a type of reproductive strategy in which a winged male carries a wingless female during mating through a complex system of genital-locking structures present in both sexes. During flight, the female is suspended from the genitalia of the male and stays in that position during much of the copulation. This kind of mating allows, in addition to the transfer of gametes, the dispersal

New symbiotic association in marine annelids: ectoparasites of comb jellies Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2020-06-23 Guillermo San Martín; Patricia Álvarez-Campos; Yusuke Kondo; Jorge Núñez; María Ana Fernández-Álamo; Fredrik Pleijel; Freya E Goetz; Arne Nygren; Karen Osborn
A new genus of ectoparasitic marine annelids living on ctenophores, Ctenophoricola gen. nov., is described and its feeding behaviour, reproduction and developmental stages are discussed. Its unusual morphology challenged its placement within the known marine families. However, analyses of mitochondrial and nuclear sequence data showed the new genus as member of the Alciopini, a group of holopelagic

Warning signals promote morphological diversification in fossorial uropeltid snakes (Squamata: Uropeltidae) Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2020-06-27 Cyriac V, Kodandaramaiah U.
AbstractMany species possess warning colourations that signal unprofitability to predators. Warning colourations are also thought to provide prey with a ‘predator-free space’ and promote niche expansion. However, how such strategies release a species from environmental constraints and facilitate niche expansion is not clearly understood. Fossoriality in reptiles imposes several morphological limits

Tracking parallel adaptation of shell morphology through geological times in the land snail genus Pupilla (Gastropoda: Stylommatophora: Pupillidae) Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2020-06-23 Martin Haase; Stefan Meng; Michal Horsák
Changing environmental conditions force species either to disperse or to adapt locally either genetically or via phenotypic plasticity. Although limits of plasticity can be experimentally tested, the predictability of genetic adaptation is restricted due to its stochastic nature. Nevertheless, our understanding of evolutionary adaptation has been improving in particular through studies of parallel

A revision of the early neotheropod genus Sarcosaurus from the Early Jurassic (Hettangian–Sinemurian) of central England Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2020-06-23 Martín D Ezcurra; Richard J Butler; Susannah C R Maidment; Ivan J Sansom; Luke E Meade; Jonathan D Radley
Neotheropoda represents the main evolutionary radiation of predatory dinosaurs and its oldest records come from Upper Triassic rocks (c. 219 Mya). The Early Jurassic record of Neotheropoda is taxonomically richer and geographically more widespread than that of the Late Triassic. The Lower Jurassic (upper Hettangian–lower Sinemurian) rocks of central England have yielded three neotheropod specimens

Tanyrhinichthys mcallisteri, a long-rostrumed Pennsylvanian ray-finned fish (Actinopterygii) and the simultaneous appearance of novel ecomorphologies in Late Palaeozoic fishes Zool. J. Linn. Soc. (IF 2.824) Pub Date : 2020-06-22 Stack J, Hodnett J, Lucas S, et al.
AbstractThe Carboniferous radiation of fishes was marked by the convergent appearance of then-novel but now common ecomorphologies resulting from changes in the relative proportions of traits, including elongation of the front of the skull (rostrum). The earliest ray-finned fishes (Actinopterygii) with elongate rostra are poorly known, obscuring the earliest appearances of a now widespread feature
