Polimorfismos de nucleótido simple (PNSs) del gen MC1R en alpacas negras y marrones

Revista Peruana de Biología, 2021
En alpacas los fenotipos del color de vellón tienen diferentes terminologías que induce a una confusión dentro del color marrón y sus tonalidades, el que requiere de una mejor descripción y cuantificación. En consecuencia los objetivos del estudio fueron

Prenatal diagnosis of cardiac rhabdomyoma: implications for predicting tuberous sclerosis complex and guiding perinatal management

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 1, Page 88-98, July 2026.
ABSTRACT Objective To identify prenatal predictors of tuberous sclerosis complex (TSC) in fetuses with one or more cardiac rhabdomyomas (CR), evaluate an integrated multimodal diagnostic workflow using fetal magnetic resonance imaging (MRI) and trio whole‐exome sequencing (trio‐WES) and characterize perinatal outcomes.

Frecuencia de fenotipos del sistema Rh en donantes voluntarios de sangre

, 2018
El sistema Rh es altamente polimórfico y está relacionado con la producción de aloanticuerpos y la enfermedad hemolítica del recién nacido. Los antígenos codificados por los genes RHD y RHCE forman el fenotipo Rh que es característico en cada población ...

Reduced fecundity associated with Wolbachia infection in a Neotropical drosophilid Redução da fecundidade associada à infecção por Wolbachia em um drosofilídeo Neotropical

Ecological Entomology, Volume 51, Issue 3, Page 475-488, June 2026.
Using multiple infected and uninfected Drosophila sturtevanti lines, we investigated (i) the impact of Wolbachia on fecundity and (ii) its effects relative to antibiotic treatment. Based on over 1680 dissected ovaries, fecundity was similar between infected and uninfected flies.

Evolution of Reproductive Plasticity in a Seasonal Tropical Environment

Ecology Letters, Volume 29, Issue 5, May 2026.
We reveal widespread occurrence of seasonal reproductive plasticity, including reproductive diapause, in Nymphalid butterflies in a seasonal rainforest in the Amazon. This highlights that, not only in temperate but also tropical habitats, seasonality is an important driver of plastic life history strategies. ABSTRACT Seasonality can drive the evolution

Anti‐Predation and Size‐Dependent Gas Exchange Functions of Amazonian Architect Cicada Towers

Biotropica, Volume 58, Issue 2, March 2026.
Clay towers built by cicada nymphs before metamorphosis are poorly understood. We experimentally show that towers of the Amazonian cicada Guyalna chlorogena reduce predation risk and exhibit size‐dependent growth responses to gas exchange obstruction, supporting their interpretation as adaptive extended phenotypes.

Estimación de la tasa de mutación hacia fenotipos mutadores

, 2023
   Intuitivamente, en una población celular coexisten células con un fenotipo wildtype (células normales, coloquialmente) y células con fenotipos mutantes (células con mutaciones). La hipótesis del fenotipo mutador, de Loeb et al.

Indigenous peoples and local community reports of climate change impacts on biodiversity

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Climate change impacts on biodiversity have been primarily studied through ecological research methods, largely ignoring other knowledge systems. Indigenous and local knowledge systems include rich observations of changes in biodiversity that can inform climate change adaptation planning and environmental stewardship.
