A review on true dung beetles' evolutionary and ecological responses to temperature and impacts on ecosystem functions

Ecological Entomology, EarlyView.
True dung beetles are a speciose group of ecosystem engineers that play key roles as detritivores in natural and agricultural landscapes. Scarabaeine beetles show strong thermal plasticity and there is increasing evidence of rapid evolutionary divergence in response to temperature across ecological and evolutionary timescales, with likely consequences ...

A new South American darter (Crenuchidae: Characidium) from rivers draining the Northeastern Mata Atlantica Freshwater Ecoregion, Brazil: morphological and molecular evidence

Journal of Fish Biology, EarlyView.
Abstract Characidium tupi, a new species from rivers draining the southern portion of the Northeastern Mata Atlantica Freshwater Ecoregion, is described. The new species can be distinguished from all congeners by its colour pattern, including 7–14 dark bars enlarged and more conspicuous on their ventralmost portion, resulting in a longitudinal series ...

Genomic changes in speciation of the family Chironomidae, Diptera [PDF]

Journal of BioScience and Biotechnology, 2015
The mode of speciation adopted by a species or group of related species of animals (insects) is clearly determined to a certain extent by the architecture of their genetic system.

Hybridization patterns between two marine snails, Littorina fabalis and L. obtusata

Ecology and Evolution, 2020
Characterizing the patterns of hybridization between closely related species is crucial to understand the role of gene flow in speciation. In particular, systems comprising multiple contacts between sister species offer an outstanding opportunity to ...

Integrative taxonomy reveals four new species of the armoured catfish genus Pareiorhina (Siluriformes: Loricariidae) from the upper Paraná River basin, Brazil

Journal of Fish Biology, EarlyView.
Abstract Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...

Assessing local adaptation and divergence at early life stages within Eastern Baltic cod (Gadus morhua)

Journal of Fish Biology, EarlyView.
Abstract Many commercially exploited fish stocks have declined over the last few decades. It is therefore essential to identify natural populations and understand local adaptation for sustainable management. Salinity is a key environmental factor shaping local adaptation, and adaptive trait divergence often occurs at the egg and larval stages.

The Agent-Based Model and Simulation of Sexual Selection and Pair Formation Mechanisms

Entropy, 2018
In this paper, the agent-based simulation model of sexual selection and pair formation mechanisms is proposed. Sexual selection is a mechanism that occurs when the numbers of individuals of both sexes are almost identical, while reproduction costs for ...

How Gaussian competition leads to lumpy or uniform species distributions [PDF]

, 2009
A central model in theoretical ecology considers the competition of a range of species for a broad spectrum of resources. Recent studies have shown that essentially two different outcomes are possible. Either the species surviving competition are more or

The variability of giraffe skull morphology

Journal of Anatomy, EarlyView.
What does giraffe skull shape tell us about their development and evolution? Abstract Giraffe (Giraffa spp.) are among the most unique and charismatic extant animals, largely due to their distinct morphology. The evolutionary and developmental origin of ossicones is a key factor in giraffid biology, yet other features building their characteristic head

Predicting distributions of Wolbachia strains through host ecological contact—Who's manipulating whom?

Ecology and Evolution, 2022
Reproductive isolation in response to divergent selection is often mediated via third‐party interactions. Under these conditions, speciation is inextricably linked to ecological context. We present a novel framework for understanding arthropod speciation
