Journal of Zoology, EarlyView.In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...

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

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.

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.

New Phytologist, Volume 248, Issue 6, Page 3256-3269, December 2025.Summary Microbe‐induced resistance (MIR) encompasses a broad range of plant responses that mediate both direct and indirect defenses against herbivores. However, previous studies have addressed MIR in relation to either direct or indirect defenses in isolation, overlooking potential conflicts or synergies that may arise between MIR‐elicited defense ...

Genotipos de resistencia antimicrobiana y su expresión fenotípica en cepas de Staphylococcus aureus
Kasmera, 2012 : Antimicrobial resistance was determined for 106 S. aureus strain isolates from patients treated in the Bacteriological Reference Center at the University Hospital Autonomous Service, Maracaibo, during the first trimester of 2009, using phenotypic and ...

New Phytologist, Volume 248, Issue 1, Page 370-388, October 2025.Summary Genomic tools have advanced our understanding of species and population structure, but distinguishing neutral from adaptive evolution remains challenging due to limited methods for measuring a broad spectrum of phenotypic traits. We used spectroscopic data from preserved leaves to test for adaptive divergence among populations of live oaks ...
