The Role of Transcription Factors in Gonad Development and Sex Differentiation of a Teleost Model Fish—Guppy (Poecilia reticulata)

open access: yesAnimals, 2020
The guppy (Poecilia reticulata) is one of the world’s most popular ornamental fish. Due to lecithotrophic viviparous, it is commonly used in toxicological studies and environmental monitoring.

Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

open access: yesThe Anatomical Record, EarlyView.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

A comprehensive dataset on the effects of Nannochloropsis sp. inclusion diets on water quality and oxidative stress of guppy (Poecilia reticulata)

open access: yesData in Brief, 2023
This experiment was designed to collect the data on antioxidants content of guppy fed with Nannochloropsis sp. inclusion diets through partial replacement of fishmeal in feed and the effect of microalgal diet on water quality parameter of the culture ...

Reviewing guppy color vision: integrating the molecular and physiological variation in visual tuning of a classic system for sensory drive

open access: yesCurrent Zoology, 2018
Sensory drive predicts coevolution of mate choice signals with the sensory systems detecting those signals. Guppies are a classic model for sensory drive as mate preferences based on coloration differ across individuals and populations.

Public Perceptions of Marital Rape: Does Level of Force Used Have an Impact?

open access: yesBehavioral Sciences &the Law, EarlyView.
ABSTRACT Research indicates that marital rape is viewed by the public as less harmful to a victim than stranger/acquaintance rape. The aim of the study is to extend the research conducted by Robinson in 2017, investigating how levels of force influence perceptions of marital rape.

'Selfish herds' of guppies follow complex movement rules, but not when information is limited [PDF]

open access: yes, 2015
Under the threat of predation, animals can decrease their level of risk by moving towards other individuals to form compact groups. A significant body of theoretical work has proposed multiple movement rules, varying in complexity, which might underlie ...

Could large‐scale silicon supplementation of crop‐lands mitigate the impacts of climate change?

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Intervention strategies that involve supplementing crop‐lands with silicon have significant scope for carbon capture and drought mitigation, offering wide‐ranging societal impacts. These include contributing to decarbonisation goals, enhancing food security, providing economic benefits and reducing environmental damage associated with intensive ...

Insect Pests Associated With Birdsfoot Trefoil, \u3ci\u3eLotus Corniculatus\u3c/i\u3e, in Wisconsin [PDF]

open access: yes, 2017
Insect surveys taken during 1984-1986 in Ashland and Bayfield Counties of northern Wisconsin revealed that several potential insect pest species were common in birdsfoot trefoil, Lotus corniculatus. Three plant bug species, including: the tarnished plant
