Phylogenomics and biogeography of the feather lice (Phthiraptera: Ischnocera) of parrots Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2024-03-13 Kevin P Johnson, Jorge Doña
Avian feather lice (Phthiraptera: Ischnocera) have undergone morphological diversification into ecomorphs based on how they escape host preening defences. Parrot lice are one prominent example of this phenomenon, with wing, body, or head louse ecomorphs occurring on various groups of parrots. Currently defined genera of parrot lice typically correspond to this ecomorphological variation. Here we explore

Morphological divergence of domatia in ant-free populations of the widespread Neotropical myrmecophyte Miconia tococa (Melastomataceae) Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2024-03-05 Alessandra Bartimachi, Thais B Pimenta, Francismeire J Telles, Ernane H M Vieira-Neto, João C F Cardoso, Heraldo L Vasconcelos, Alan N Costa
Co-evolving organisms experience multiple selection pressures that may lead to trait mismatches among different populations and sites. In defensive ant–plant mutualisms, host plants (myrmecophytes) produce specialized shelters (domatia) to harbour specialized ant-partners in exchange for protection against enemies. Although populations of myrmecophytes without ants occur in some locations, there are

Weapon allometry and shape variation in the Helm’s stag beetle (Geodorcus helmsi) Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2024-03-02 L Grey, G I Holwell, J M Jandt, S Johnson
Many animals develop and use exaggerated weapons in contests over access to mating opportunities. Stag beetles (family Lucanidae) show striking sexual dimorphism, where the males have heavily exaggerated mandibles that the females do not possess. In some genera, size and shape can also vary drastically between small and large males resulting in discrete alternative male morphs, described as male dimorphism

Testing ‘bigger is better’ and maternal effects hypotheses in hatchlings of the sexually dimorphic spiny softshell turtle (Apalone spinifera) Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2024-01-20 Eden Porter, James E Paterson, Christina M Davy
The ‘bigger is better’ hypothesis (BIBH) predicts that fitness increases with body size. Eastern spiny softshell turtles (Apalone spinifera) exhibit sexual size dimorphism (SSD) at maturity, and the much larger female body size is attributed to selection favouring greater reproductive output. Hatchlings exhibit sexually dimorphic markings, but hatchling SSD has not been investigated. The BIBH predicts

Claustral colony founding is limited by body condition: experimental feeding increases brood size of Lasius niger queens (Hymenoptera: Formicidae) Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2023-11-07 Norbert Szabó, Jenő Nagy, András Tartally
Ants can found colonies in different ways. One is by claustral colony foundation, when fertilized queens typically have enough nutrients reserved in their bodies to raise the first ‘nanitic’ worker generation without any foraging activity. This colony-foundation strategy evolved in response to selective pressures (e.g. predators), but it limits the number of nanitic workers. We, therefore, assumed

Coastal dwarf variants of the red swamp Banksia (Proteaceae) represent parallel ecotypic evolution rather than a divergent evolutionary lineage of single origin Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2023-10-19 Timothy P Robins, Rachel M Binks, Margaret Byrne, Stephen D Hopper
Morphological variation is common within widely distributed plant species and often raises interesting taxonomic and evolutionary questions. We sampled eight typical inland populations and two coastal dwarf populations of Banksia occidentalis to assess whether the coastal variant warrants taxonomic recognition. Genomic (single nucleotide polymorphisms) and morphometric analyses were undertaken to assess

Highland islands: assessing gene flow among populations of an aquatic highland endemic Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2023-10-17 Kyle R Piller, Elyse Parker, Caleb D McMahan, Diego J Elías, Wilfredo A Matamoros, Ernesto Velázquez Velázquez
A variety of hierarchical gene flow models have been proposed to explain the distribution of genetic variation in aquatic environments. These models, including the Stream Hierarchy (SH), Death Valley (DV), Headwater (HW), and Widespread Gene flow (WG) models, provide testable hypotheses that focus on the degree of within-basin or within-stream network connectivity and an organism’s dispersal abilities

Phylogeography of two codistributed terrestrial snails in the Maputaland–Pondoland–Albany biodiversity hotspot, South Africa Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2023-10-14 Evelyn M Raphalo, Mary L Cole, Savel R Daniels
We investigated the evolutionary patterns of two forest-dwelling endemic terrestrial snails (Gittenedouardia spadicea and Maizania wahlbergi) in the Maputaland–Pondoland–Albany biodiversity hotspot in South Africa to examine the degree of phylogeographical congruence between the two species. Phylogenetic relationships and divergence time estimations within each species were inferred using the combined

A picture is worth a thousand dollars: a photographic approach to studying colour in anoles Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2023-10-14 Jake A Jacobs, Jhan C Salazar, Kristin M Winchell
Colours relay information to conspecifics and predators unique to an environment and are shaped by natural selection favouring colours that enable higher fitness. For decades, ecologists have grappled with various methods of quantifying colour. Spectrophotometers offer precise and accurate data, but their high price limits accessibility. Here we test the validity of an accessible method of quantifying

Lineage diversification of the Sky Island treefrog Scinax curicica (Anura, Hylidae) in the Espinhaço Mountain Range Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2023-10-14 Diego J Santana, Eric Ragalzi, Ricardo Koroiva, Sarah Mângia, Karoline Ceron, Felipe S F Leite, Donald B Shepard
Sky Islands present unique landscapes for organismal evolution because they comprise high mountain peaks separated by low valleys with vastly different environmental conditions. The Espinhaço Mountain Range in eastern Brazil is formed of groups of Sky Islands in the states of Minas Gerais and Bahia. Several phylogeographic studies have discovered strong genetic structure among populations of organisms

Evolution of Skipper (SK), a family of DD34E/Tc1 transposons, in animals Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2023-10-13 Saisai Wang, Zhongxia Guan, Mohamed Diaby, Emmanuel Asare, Numan Ullah, Wenzhu Jia, Bo Gao, Duonan Yu, Chengyi Song
High diversity and differential evolution profiles have been observed for DD34E/Tc1 transposons; several families originating from these groups, such as DD34E/ZB, DD34E/SB, DD35E/TR, DD36E/IC, and DD38E/IT, have been well defined. Even though Frisky, Tiang, Tsessebe, and Topi transposons have been identified in Anopheles gambiae, their taxonomic distribution and phylogenetic relationship in nature

Transcriptome analysis of anuran breeding glands reveals a surprisingly high expression and diversity of NNMT-like genes Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2023-10-13 Lisa M Schulte, Evan Twomey, Julia Jendras, Raciel Cruz-Elizalde, Franky Bossuyt
In many amphibians, males have sexually dimorphic breeding glands, which can produce proteinaceous or volatile pheromones, used for intraspecific communication. In this study we analyse two types of glands in the Mexican treefrog Ptychohyla macrotympanum (Hylidae)—large ventrolateral glands and small nuptial pads on their fingers—using histology, whole-transcriptome sequencing, and phylogenetic analyses

A diving beetle’s dilemma: the impact of sexual conflict on Rensch’s rule Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2023-10-10 Mariah Polido, Vinicius M Lopez, Guilherme Gonzaga da Silva, Marco A Del Lama, Rhainer Guillermo-Ferreira
Sexual conflict is believed to be an important evolutionary force driving phenotypic diversification, especially sexual dimorphism. Males of diving beetles sometimes resort to coercive tactics to increase their chances of successful reproduction, which can impose costs on females. Sexual conflict can also drive sexual size dimorphism (SSD), particularly in species where males are larger than females

Molar wear in house mice: insight into diet preferences at an ecological timescale? Biol. J. Linn. Soc. (IF 1.9) Pub Date : 2023-10-10 Sabrina Renaud, Ronan Ledevin, Anne-Béatrice Dufour, Caroline Romestaing, Emilie A Hardouin
In molars without permanent eruption, wear deeply modifies the geometry of the crown. To test for a signature of diet on wear dynamics, the molar geometry was compared between commensal house mice, relying on an omnivorous-granivorous diet, and Sub-Antarctic relatives, characterized by a switch towards a more ‘predatory’ behaviour. Laboratory-bred offspring of commensal mice served as a reference by
