Unlearned adaptive responses to heterospecific referential alarm calls in two bird species from separate evolutionary lineages

Scientific Reports, 2023
The interspecific responses to alarm signals may be based on unlearned mechanisms but research is often constrained by the difficulties in differentiating between unlearned and learned responses in natural situations.

The Target Selects the Toxin: Specific Amino Acids in Snake-Prey Nicotinic Acetylcholine Receptors That Are Selectively Bound by King Cobra Venoms

Toxins, 2022
Snake venom is an adaptive ecological trait that has evolved primarily as a form of prey subjugation. Thus, the selection pressure for toxin diversification is exerted by the prey’s physiological targets, with this pressure being particularly acute for ...

Correlates of early reproduction and apparent fitness consequences in male Soay sheep

Ecology and Evolution, 2023
Life history trade‐offs are ubiquitous across species and place constraints on the timing of life history events, including the optimal age at first reproduction.

Detailed kinship estimation for detecting bias among breeding families in a reintroduced population of the endangered bagrid catfish Tachysurus ichikawai

Population Ecology, EarlyView.
In the process of captive breeding and reintroduction of endangered animal species, it is crucial to minimize familial bias in reproductive success during the reintroduction phase to preserve genetic diversity. In this study, we attempted to identify the familial lineage of individuals of the endangered bagrid fish Tachysurus ichikawai born at the ...

Freudarwin: Evolutionary Thinking as a Root of Psychoanalysis

Frontiers in Psychology, 2018
This essay synthesizes the place of biological evolutionism in the early history of psychoanalysis, and shows the implicit significance of German Darwinism in Sigmund Freud’s whole psychoanalytical works.

Origin of Life: The Point of No Return

Life, 2020
Origin of life research is one of the greatest scientific frontiers of mankind. Many hypotheses have been proposed to explain how life began. Although different hypotheses emphasize different initial phenomena, all of them agree around one important ...

The influence of immune challenges on the mean and variance in reproductive investment: a meta-analysis of the terminal investment hypothesis

BMC Biology, 2023
Finding the optimal balance between survival and reproduction is a central puzzle in life-history theory. The terminal investment hypothesis predicts that when individuals encounter a survival threat that compromises future reproductive potential, they ...

Optimal SNP filtering strategies for pedigree reconstruction: A case study with wild red‐spotted masu salmon population

Population Ecology, EarlyView.
In this article, we tested optimal SNP filtering strategies for accurate parentage assignment and pedigree reconstruction for a wild population of red‐spotted masu salmon, Oncorhynchus masou ishikawae. We found that mid‐point filtering in terms of call rate and minor allele frequency performs well for pedigree reconstruction.

Age structure landscapes emerge from the equilibrium between aging and rejuvenation in bacterial populations

Nature Communications, 2018
Some daughter cells inherit the maternal old pole during bacterial division, but does this correspond to aging? Here, Proenca et al. show that constant patterns of aging and rejuvenation connect distinct growth equilibria within bacterial clonal ...
