Methyl Jasmonate and Methyl Salicylate Differentially Modulate Direct and Indirect Defenses in Coffee Plants Against the White Mealybug

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
MeJA application strengthened both direct and indirect coffee defenses against the white mealybug Planococcus citri, whereas the effects of MeSA were variable and context‐dependent across the defensive traits examined. The combined application of both elicitors produced an effect similar to MeSA on direct defenses, but resembled MeJA when indirect ...

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Nutritional Stress Modulates Developmental Thresholds in a Male Dimorphic Mite

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Global warming can alter nutrition during development, but whether this affects phenotype expression solely through changes in condition or also through developmental decision‐making remains unclear. In the male‐dimorphic bulb mite Rhizoglyphus robini, nutritional stress shifted the developmental threshold for fighter versus scrambler expression and ...

Management and tree dieback alter beetle assemblage structure and body size distribution in a temperate German forest

open access: yesEcological Entomology, EarlyView.
Forest management and climate‐induced tree dieback alter the structural characteristics of forests, which could subsequently lead to changes in the structure of beetle assemblages. Beetle assemblages in more open forests exhibited less even abundance distributions, with fewer, more dominant species (higher rates of decline (r), higher dominance (d ...

Microbiome‐mediated immunity: Limited support from the gazelle dung beetle

open access: yesEcological Entomology, EarlyView.
Digitonthophagus gazella rely on a maternally inherited microbiome passed across generations via a maternal faecal pellet called the pedestal. We experimentally manipulated the presence of the pedestal, providing it to some individuals while withholding it from others to determine how pedestal microbiota may affect beetle immune potential.

Professional Training and Clinical/Radiographic Factors Associated With Endodontic Decision‐Making: A Before‐and‐After Study

open access: yesEuropean Journal of Dental Education, EarlyView.
ABSTRACT Introduction Endodontic decision‐making is influenced by clinicians' professional training and by the clinical and radiographic characteristics of each case. This study aimed to assess the association of these factors with treatment decisions and to determine whether the addition of clinical information modifies treatment choices compared with

Post‐Hoc Long‐Read Sequencing Links Leukemic Mutation Status to Single‐Cell Transcriptomes

open access: yesEuropean Journal of Haematology, EarlyView.
ABSTRACT Single‐cell RNA‐sequencing‐based characterization of cells that belong to the neoplastic clone is a major challenge in hematologic neoplasms, where malignant and normal cells coexist. Confident molecular profiling requires simultaneous analysis of gene expression and genetic mutations in individual cells, an ability that is not supported by ...

The Liquidity Sprint: Short‐Term Cash Needs and Access to Credit

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT We identify the causal drivers of the COVID‐19 ‘dash‐for‐cash’ in Europe using a hand‐collected panel of Euro‐area firms (2018‐Q4–2020‐Q3). Exploiting regional infection intensity as an instrument, we find that a one‐unit EBITDA decline raised credit‐line utilization by 15.5 percentage points in 2020‐Q2. Unlike the US ‘fallen‐angel’ narrative,

Risk Perceptions and Corporate Financing Behavior

open access: yesFinancial Management, EarlyView.
ABSTRACT Using a recently developed measure of financial market risk perceptions, we show that risk perceptions affect firm‐level corporate financing behavior. Firms tend to adjust their capital structures to cater to investors' appetite for risk. When perceived risks are low, firms tend to choose more leveraged capital structures to take advantage of ...

Choosing Startup Investors: Does Gender Matter?

open access: yesFinancial Management, EarlyView.
ABSTRACT We investigate whether startups respond differently to male and female investors during outbound origination, a setting where female investors often report being marginalized by male founders. Using a randomized field experiment, we examine gender differences in startups' responses to investor outreach.
