Sexual differences in spectral sensitivity and wing colouration of 13 species of Japanese Thecline butterflies (Lepidoptera: Lycaenidae)

open access: yesEuropean Journal of Entomology, 2013
The correlation between dorsal wing colours and spectral sensitivity of the compound eyes of 13 species of thecline butterflies, consisting of 8 sexually monomorphic and 5 dimorphic species, was investigated.

Genetic population structure of red foxes Vulpes vulpes across a rural landscape: insights into population connectivity and spatial patterns

open access: yesWildlife Biology, EarlyView.
Human activities have shaped and are continuing to influence terrestrial landscapes, creating heterogenous, and often, fragmented landscapes. Generalist species, like the red fox Vulpes vulpes, show high flexibility in habitat use, and occur across the heterogeneous, anthropogenic landscapes of central Europe.

Color polymorphic carnivores have faster speciation rates

open access: yesScientific Reports
Variation in coat color is a prominent feature in carnivores, thought to be shaped by environmental factors. As new traits could allow populations to occupy novel niches and habitats, color polymorphism may be maintained by balancing selection ...

Development of a reliable PCR‐based protocol for molecular sexing of king vultures Sarcoramphus papa

open access: yesWildlife Biology, EarlyView.
The king vulture Sarcoramphus papa is a large Neotropical scavenger that lacks external sexual dimorphism, complicating demographic, ecological, and conservation studies. Reliable sex identification is therefore essential, particularly for wild and managed populations. In this study, we assessed and optimized a PCR‐based molecular sexing protocol for S.

Geological Substrate Is Related to Tooth Senescence and Population Dynamic: The Case Study of Alpine Chamois (Rupicapra rupicapra L.)

open access: yesIntegrative Zoology, EarlyView.
In Alpine chamois, the complete wear of the first molar coincides with the beginning of senescence and the progress of tooth wear on calcareous substrate is slower than the one on other substrates, increasing life expectancy. Thus, the first molar wear may actually be considered as an effective descriptor of senescence stage.

Sexual segregation in monomorphic minnows

open access: yes, 2014
Sexual segregation, where males and females use habitat in different ways, is widespread among animals including fish, and has important consequences for key aspects of population ecology including foraging success, predator avoidance and growth. However,

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Female‐Biased Sexual Size Dimorphism and Its Potential Causes in Hairy‐Winged Bats

open access: yesIntegrative Zoology, EarlyView.
Based on the integration of molecular genetics, traditional and geometric morphology, and acoustic characteristics of hairy‐winged bats (a species that was historically misclassified into two species due to extreme craniodental divergence between the sexes) in multiple regions of China, we quantified the sexual size dimorphism (SSD) between males and ...
