Prolonged low flows and non‐native fish operate additively to alter insect emergence in mountain streams

open access: yesLimnology and Oceanography, EarlyView.
Abstract Climate‐induced flow alteration is decreasing snowpack and advancing snowmelt, subjecting mountain streams to longer low‐flow periods. Yet, anticipating how stream ecosystems respond to prolonged low flows remains challenging because distinct trophic levels can respond differently, and non‐native predators can dampen or amplify responses. Here,

Herbivores induce plant chemical defenses based on the identity of their attacking parasitoid

open access: yesOikos, EarlyView.
Many parasitoids increase plant fitness by decreasing herbivore feeding damage. Solitary parasitoids (where only one individual completes development per host) generally cause their hosts to feed less than unparasitized herbivores, reducing pressure on plants to induce chemical defense production.

Can Butterflies Evade Fire? Pupa Location and Heat Tolerance in Fire Prone Habitats of Florida

open access: yesPLoS ONE, 2015
Butterflies such as the atala hairstreak, Eumaeus atala Poey, and the frosted elfin, Callophrys irus Godart, are restricted to frequently disturbed habitats where their larval host plants occur.

Metabolism of Epoxidised Withanolides by a Generalist and a Specialist Insect Species

open access: yesChemistryOpen, EarlyView.
Larvae of Heliothis (Chloridea) virescence and subflexa have the ability to convert the epoxidized terpenoid 4β‐hydroxywithanolide E (4BHWE) to withanolide S. The conversion is found by feeding the larvae an artificial diet supplemented with 13C‐labeled 4BHWE.

Development of a dynamic population model as a decision support system for Codling Moth (Cydia pomonella L) management [PDF]

open access: yes, 2008
In 2004 RIMpro-Cydia was developed as a dynamic population model that simulates the within-year biology of a local codling moth population. The model is meant to be used by growers and advisors to optimize the control of codling moth populations in ...

Ternary Microphase Diagram of SBM Triblock Terpolymer Morphologies in Spherical Confinement

open access: yesJournal of Polymer Science, EarlyView.
ABSTRACT Block copolymers are a versatile class of soft materials, as they combine different chemical and physical properties within the same macromolecule. Triblock terpolymers are of particular interest because of the numerous morphologies they can form. With the aim of generating a comprehensive ternary microphase diagram, we emulsified 22 different

Responses of generalist invertebrate predators to pupal densities of autumnal and winter moths under field conditions [PDF]

open access: yes, 2013
1. Generalist natural enemies are usually not considered as being capable of causing population cycles in forest insects, but they may influence the population dynamics of their prey in the low density cycle phase when specialist enemies are largely ...
