Rare morph Lake Malawi mbuna cihclids benefit from reduced aggression from con- and heterospecifics

Alexandra Tyers
Balancing selection is important for the maintenance of polymorphism as it can prevent either fixation of one morph through directional selection or genetic drift, or speciation by disruptive selection. Polychromatism, the presence of multiple genetically determined colour phenotypes, can be maintained if the fitness of alternative morphs depends on the relative frequency in a population. In aggressive species, negative frequency-dependent antagonism can prevent an increase in the frequency of rare morphs as they would only...

Low-cost tools mitigate climate change during reproduction in an endangered marine ectotherm

Leo Clarke, Rebecca Elliot, Elena Abella-Perez, Adolfo Marco, Samir Martins & Lucy Hawkes
The impacts of anthropogenic climate change will be most dramatic for species that live in narrow thermal niches, such as reptiles. Given the imminent threat to biodiversity, and that actions to reduce carbon emissions are not yet sufficient, it is important that a sound evidence base of potential mitigation options is available for conservation managers. Successful incubation and production of male sea turtle hatchlings is threatened by increased global temperatures (sex is determined by the...

Data: Genomic signatures of admixture and selection are shared among populations of Zaprionus indianus across the western hemisphere

Aaron A. Comeault, Andreas F. Kautt & Daniel R. Matute
Introduced species have become an increasingly common component of biological communities around the world. A central goal in invasion biology is therefore to identify the demographic and evolutionary factors that underlie successful introductions. Here we use whole genome sequences, collected from populations in the native and introduced ranges of the African fig fly, Zaprionus indianus, to quantify genetic relationships among them, identify potential sources of the introductions, and test for selection at different spatial scales....

Contrasting selection pressure on body and weapon size in a polygynous megaherbivore

Graeme Shannon, Phoebe Sadler, Joanna Smith, Eleanor Roylance-Casson & Line S. Cordes
Sexual size dimorphism (SSD) is a common morphological trait in ungulates, with polygyny considered the leading driver of larger male body mass and weapon size. However, not all polygynous species exhibit SSD, while molecular evidence has revealed a more complex relationship between paternity and mating system than originally predicted. SSD is, therefore, likely to be shaped by a range of social, ecological and physiological factors. We present the first definitive analysis of SSD in the...

Genomic survey of edible cockle (Cerastoderma edule) in the Northeast Atlantic: a baseline for sustainable management of its wild resources

Paulino Martínez Portela, Manuel Vera, Francesco Maroso, Sophie Wilmes, Miguel Hermida, Andrés Blanco, Carlos Fernández, Emily Groves, Shelagh Malham, Carmen Bouza, Peter Robins & Paulino Martínez
Knowledge on how environmental factors shape the genome of marine species is crucial for sustainable management of fisheries and wild populations. The edible cockle (Cerastoderma edule) is a marine bivalve distributed along the Northeast Atlantic coast of Europe and is an important resource from both commercial and ecological perspectives. We performed a population genomics screening using 2b-RAD genotyping on 9,309 SNPs localised in the cockle's genome on a sample of 536 specimens pertaining to 14...

Whole genome resequencing data enables a targeted SNP panel for conservation and aquaculture of Oreochromis cichlid fishes

Adam Ciezarek, Antonia Ford, Graham Etherington, Nasser Kasozi, Milan Malinsky, Tarang Mehta, Luca Penso-Dolfin, Benjamin Ngatunga, Asilatu Shechonge, Rashid Tamatamah, Wilfried Haerty, Federica Di Palma, Martin Genner & Turner George
Cichlid fish of the genus Oreochromis form the basis of the global tilapia aquaculture and fisheries industries. Broodstocks for aquaculture are often collected from wild populations, which in Africa may be from locations containing multiple Oreochromis species. However, many species are difficult to distinguish morphologically, hampering efforts to maintain good quality farmed strains. Additionally, non-native farmed tilapia populations are known to be widely distributed across Africa and to hybridize with native Oreochromis species, which themselves...

Ancient geological dynamics impact neutral biodiversity accumulation and are detectable in phylogenetic reconstructions

Leonel Herrera-Alsina, Adam Algar, Greta Bocedi, Cecile Gubry-Rangin, Lesley Lancaster, Poppy Mynard, Owen Osborne, Alexander Papadopulos, Simon Creer, Meis Nangoy, Fahri Fahri, Pungki Lupiyaningdyah, I Made Sudiana, Berry Juliandi & Justin Travis
Aim Landmasses have been continuously modified by tectonic activity, the breakup and collision of landmasses is thought to have generated or suppressed ecological opportunities, altering the rates of speciation, dispersal and extinction. However, the extent to which the signatures of past geologic events are retained in modern biodiversity patterns - or obliterated by recent ecological dynamics - remains unresolved. We aim to identify the fingerprint of different scenarios of geological activity on phylogenetic trees and...

Past deforestation (2000-2018) and future deforestation probability (2019-2053) for Wallacea

M. Voigt, J. Supriatna, N.J. Deere, A. Kastanya, S.L. Mitchell, I.M.D. Rosa, T. Santika, R. Siregar, J.S. Tasirin, A. Widyanto, N.L. Winarni, Z. Zakaria, S. Mumbunan, Z.G. Davies & M.J. Struebig
Primary forest cover and forest cover loss in Wallacea for the years 2000-2018 to train a deforestation model and produce maps of projected probability of deforestation until 2053.

Urination data for Welsh Mountain ewes grazing upland and lowland pastures in North Wales, 2016

K.A. Marsden, L. Lush, J.A. Holmberg, M.J. Whelan, A.J. King, R.P. Wilson, A.F. Charteris, L.M. Cardenas, D.L. Jones & D.R. Chadwick
The data contains urination metrics including frequency, volume, chemical composition, estimated urine patch N loading rates and metabolomics profile of individual urine events from sheep (Welsh Mountain ewe) grazing a semi-improved upland pasture and a lowland improved pasture located in North Wales, UK. Urine collection studies were run in the spring, summer and autumn of 2016 for the semi-improved site and in autumn of 2016 on the lowland improved pasture. Sheep were housed in urine...
