1H NMR Profiling of Honey Bee Bodies Revealed Metabolic Differences between Summer and Winter Bees

Abstract: In temperate climates, honey bee workers of the species Apis mellifera have different lifespans depending on the seasonal phenotype: summer bees (short lifespan) and winter bees (long lifespan). Many studies have revealed the biochemical parameters involved in the lifespan … Read More

Plant-based and immunostimulant-enhanced diets modulate oxidative stress, immune and haematological indices in rainbow trout (Oncorhynchus mykiss)

Abstract: The aim of this study was to investigate the effects of three commercial diets, standard, immunostimulant-supplemented (β-glucan, vitamins C and E) and plant-based, on the degree of oxidative stress in tissues of rainbow trout (Oncorhynchus mykiss). Selected immune and … Read More

Changes in haemolymph parameters and insect ability to respond to immune challenge during overwintering

Abstract: Overwintering is a challenging period in the life of temperate insects. A limited energy budget characteristic of this period can result in reduced investment in immune system. Here, we investigated selected physiological and immunological parameters in laboratory-reared and field-collected … Read More

Winter honeybee (Apis mellifera) populations show greater potential to induce immune responses than summer populations after immune stimuli

Abstract: In the temperate climates of central Europe and North America, two distinct honeybee (Apis mellifera) populations are found in colonies: short-living summer bees emerge in spring and survive until summer, whereas long-living winter bees emerge in late August and … Read More

Vigour-related traits and immunity in hybrids of evolutionary divergent cyprinoid species: advantages of hybrid heterosis?

Abstract Hybrid advantage, described as the superiority of hybrids in some traits over their parents and termed the “heterosis effect,” is widely documented in the case of reciprocal crosses of parental species (i.e., hybrids representing the F1 generation). In fish, … Read More

Special Issue „Insects, Nematodes and Their Symbiotic Bacteria“

Dear Colleagues, Insect pathogenic nematodes (entomopathogenic nematodes—EPNs) are lethal parasites to their hosts, and are frequently used as biological agents in the control of insect pests. Lethality may be as a result of the virulence factors provided by the nematodes … Read More

Differences in the growth rate and immune strategies of farmed and wild mallard populations

Individuals reared in captivity are exposed to distinct selection pressures and evolutionary processes causing genetic and phenotypic divergence from wild populations. Consequently, restocking with farmed individuals may represent a considerable risk for the fitness of free-living populations. Supportive breeding on … Read More

Heptabladed β‐propeller lectins PLL2 and PHL from Photorhabdus spp. recognize O‐methylated sugars and influence the host immune system

O‐methylation is an unusual sugar modification with a function that is not fully understood. Given its occurrence and recognition by lectins involved in the immune response, methylated sugars were proposed to represent a conserved pathogen‐associated molecular pattern. We describe the … Read More
