Linking the hierarchical decisionmaking process of fruit choice and the phenotypic selection strength on fruit traits by birds
(Oxford University Press, 2017-08)
Aims: Animals in search of fleshy fruits forage mostly according to the number of available fruits and then select individual fruits based on reward quality or advertised subtle traits. This hierarchical pattern of fruit ...
Adverse outcomes of pregnancy and blood groups: A relationship with no importance?
(1994)
Seeking a relationship between blood groups and successful pregnancy, Linn’s group carried out an analysis using the med- ical records of 11,659 women. They found a significantly higher frequency of bleeding during pregnancy ...
Is the evolutionary theory still useful?: A review with examples

Bases antropológico-filosóficas de las aportaciones del constructivismo epistemológico a la didáctica
Muchas de las teorías educativas actuales son de corte constructivista. En este artículo, reflexionamos sobre diversas cuestiones antropológico-filosóficas que justifican los postulados del constructivismo aplicados a la ...
Intense natural selection preceded the invasion of new adaptive zones during the radiation of New World leaf-nosed bats
(Nature Publishing Group, 2017-12)
The family Phyllostomidae, which evolved in the New World during the last 30 million years, represents one of the largest and most morphologically diverse mammal families. Due to its uniquely diverse functional morphology, ...

Directional, stabilizing, and disruptive trait selection as alternative mechanisms for plant community assembly
(Ecological Society of America, 2017-03-30)
How plant functional traits (e.g., seed mass) drive species abundance within communities remains an unsolved question. Borrowing concepts from natural selection theory, we propose that trait-abundance relationships can ...
Landscape genomics: Natural selection drives the evolution of mitogenome in penguins
(BioMed Central, 2018-01)
Background: Mitochondria play a key role in the balance of energy and heat production, and therefore the mitochondrial genome is under natural selection by environmental temperature and food availability, since starvation ...
