Drosophila disengage systemic protein storage as an evolutionary response to chronic larval malnutrition

Abstract. Nutritional geometry was used to explore the effects of dietary composition on larval developmental traits in Drosophila melanogaster populations

Phylogenomic and demographic history of the Cape cliff lizard (Hemicordylus capensis)

Abstract. Hemicordylus capensis, the Cape cliff lizard, is endemic to South Africa and occurs across the entire range of the Cape Fold Mountains. Despite p

Warts and all: evolutionary and ecological patterns in frog skin texture

Abstract. The external appearance of frog skin varies among species and across body regions. Although this variation has long been recognized, it remains a

Individual condition mediates the costs of sexual conflict through both male harm and female resistance

Abstract. Sexual conflict arises when the reproductive interests of males and females diverge, leading to decreased female fitness due to male‐induced harm

Absence of dispersal-mediated selection on the expression of a female ornament—a long-term study in a wild bird population

Abstract. There is increasing evidence that female ornamentation is not merely a genetic by-product of male ornamentation and has evolved through sexual an

Historical shifts and ecological patterns: rethinking genome size evolution in Coffea L

Abstract. Although genome size (GS) is decoupled from organismal complexity, a phenomenon known as the C-value paradox, some authors have proposed that GS

Telomere dynamics, not absolute telomere length, predicts lifespan in adult zebra finches

Abstract. Telomeres shorten with age, and telomere length (TL) can predict lifespan. In vitro studies have established that the shortest telomeres in the g

Replication fidelity difference between daughter chains persists during evolution

Abstract. While mutations are the engine of evolution, how mutation rates themselves evolve remains poorly understood. Previous simulation and experimental

Extending space-for-time substitutions: the missing role of the gut microbiome

Abstract. The space-for-time substitution (SFTS) approach is widely used to predict evolutionary trait responses to global warming. The current approach ig

Gene expression profiling across the three-host life cycle of Schistocephalus solidus: how decoupled are the life stages?

Abstract. Parasites with complex life cycles infect multiple hosts, adapting to different ecological niches using a single genome. The adaptive decoupling

Queen loss fails to elicit physiological and transcriptional responses in workers of the invasive garden ant Lasius neglectus

Abstract. Colonies of insects with morphologically distinct castes have been called superorganisms because the function of their queens and workers is anal

Inclusive fitness for the conflicted individual

Abstract. The theory of inclusive fitness explains the process and purpose of social adaptation. However, the canonical derivation of inclusive fitness ass

Independent origin of sperm heteromorphism in the Drosophilidae

Abstract. Sperm heteromorphism, the production multiple discrete sperm types (or “morphs”), occurs in diverse animal and plant taxa. This phenomenon repres

What about male quality? A model to predict male investment in a single female

Abstract. Monogyny—where a male invests all his reproductive effort in a single female—is a rare and poorly understood mating system. It contradicts conven

Evolution of divergent daily temporal niches shaped by male–male competition can generate sympatric speciation

Abstract. Specialisation into different ecological niches is assumed as an important driver of speciation in sympatry. Here, we focused on male–male compet

Burrowing behaviour and species recognition predict colour pattern evolution in freshwater crayfishes

Abstract. Colour patterns are the spatial arrangements of contrasting colours on an organism’s body and can have several non-mutually exclusive functions,

Clinging strength, but not sprint speed, underlies morphological divergence between ecologically distinct Liolaemus species

Abstract. Biomechanical theory suggests a strong link between an organism’s physical structure and its ability to perform specific functions. Animals speci

Predation and the evolution of island bird plumage colouration: experimental insights from island and mainland environments

Abstract. Islands serve as natural laboratories for exploring evolutionary processes, often fostering unique species through isolation and distinct ecologi

Chromosomal rearrangements: tempo and mode of karyotype evolution in Scarabaeoidea

Abstract. Karyotype evolution, including changes in chromosome number and structure, is a fundamental process that can influence genome organization and sp

Non-genetic inheritance of induced defense morphologies across multiple unexposed generations of Daphnia lumholtzi

Can the ghosts of environments past shape organismal phenotypes of future generations? In an experiment with clonal Daphnia lumholtzi we reveal that predat

Hidden in plain sight: a novel symbiotic haplosclerid sponge species revealed by its mitochondrial genome

Abstract. Sponges (phylum Porifera) are known to form symbiotic relationships with a variety of organisms, including other sponges. Recently, such symbiosi
