Abstract:
... BACKGROUND: Freezing injury is a devastating yet common damage that occurs to winter rapeseed during the overwintering period which directly reduces the yield and causes heavy economic loss. Thus, it is an important and urgent task for crop breeders to find the freezing-tolerant rapeseed materials in the process of breeding. Existing large-scale freezing-tolerant rapeseed material recognition meth ...

Abstract:
... Small heat shock proteins (sHSPs) are conserved proteins that play key roles in organismal adaptation to adversity stressors. However, little is known about sHSPs during summer diapause. Three sHSP genes: PmHSP19.5, PmHSP19.9, and PmHSP20.0 were identified and cloned from Pieris melete. Sequence alignment and phylogenetic analysis revealed that the three sHSPs have a typical, conserved α-crystalli ...

Abstract:
... Honey Bees are very important to ecological environment and human society. However, the collapse of bee colonies in winter has frequently occurred in recent years, so condition monitoring of bee colonies is vital to maintain bee colonies health. Considering that the temperature has the strongest ability of recognizing the status of bee colonies, this paper uses a multi-sensor system to investigate ...

Abstract:
... Light stress is one of the important stresses for winter survival in evergreens, especially for plants with broad leaves, like evergreen rhododendrons. Photoprotection has been shown to upregulate dramatically in rhododendrons during winter, but whether it directly contributes to enhancing the freezing tolerance is still unknown. In this study, we found that the expression and circadian rhythm of ...

Abstract:
... Overwintering females in the third generation of Pseudaulacaspis pentagona (Targioni Tozetti) (Hemiptera: Diaspididae) entered reproductive diapause with undeveloped ovarian eggs. Ovarian development in females collected before the winter solstice was retarded, but development proceeded normally thereafter. Neither length of photoperiod nor changing photoperiods affected the induction of reproduct ...

Abstract:
... Exposure to pesticides is a major threat to bumblebee (Bombus spp.) health. In temperate regions, queens of many bumblebee species hibernate underground for several months, putting them at potentially high risk of exposure to soil contaminants. The extent to which bumblebees are exposed to residues in agricultural soils during hibernation is currently unknown, which limits our understanding of the ...

Abstract:
... A unique opportunity to study the sexual reproduction of Chlamydomonas proboscigera was presented when this species reached high densities in the Vaal River, South Africa during 2019. A peculiar and unique way of sexual reproduction in C. proboscigera was revealed for the first time and differs from earlier knowledge on the sexual reproduction of this species. Evidence of copulating gametes obtain ...

Abstract:
... Bactrocera dorsalis (Hendel) is an important pest to fruits and vegetables. It can damage more than 300 plant species. The distribution of B. dorsalis has been expanding owing to international trade and other human activities. B. dorsalis occurrence is strongly related to suitable overwintering conditions and distribution areas, but it is unclear where these seasonal and year-round suitable areas ...

Abstract:
... The development of the ovary of Onychostoma macrolepis undergoes distinct annual cyclic changes in which small non-coding RNAs (sncRNAs) could play vital roles. In this study, four sncRNA classes in the ovary, including miRNA, piRNAs, tsRNA, and rsRNAs, were systematically profiled by high-throughput sequencing. In adult ovaries of O. macrolepis, 247 miRNAs and 235 tsRNAs were identified as differ ...

Abstract:
... Some jumping plant-lice species are economically important due to their capacity as vectors of phytopathogenic bacteria, for example phytoplasmas. Previous studies have identified 80 jumping plant-louse species from Hungary; however, little is known about their occurrence during winter. To extend our knowledge of overwintering sites of jumping plant-lice in Hungary, we sampled them from conifers i ...

Abstract:
... Several overwintering crane species like Black-necked cranes (Grus nigricollis) mainly depends on wetlands for foraging or roosting, preferring stable water depths. Understating the wading depths of cranes is a pressing concern for the better management of wetlands and robust conservation of the overwintering cranes populations. Yet, practically it is very difficult to precisely measure the wading ...

Abstract:
... Overwintering is a key demographic stage for migratory birds but remains poorly understood, especially among multiple declining grassland bird species. The non‐breeding ranges all 4 species of longspur (i.e., chestnut‐collared [Calcarius ornatus], Smith's [C. pictus], Lapland [C. lapponicus], thick‐billed [Rhynchophanes mccownii]) overlap in Oklahoma and the Texas Panhandle, USA, making this regio ...

Abstract:
... Lumpy skin disease is an emerging transboundary infection demonstrating a great range expansion worldwide recently. With many knowledge gaps, there is a lack of understanding how lumpy skin disease virus (LSDV), including naturally occurring vaccine‐like LSDV, is capable of surviving under different climatic conditions. In this study, we describe a recombinant vaccine‐like LSDV from an outbreak in ...

Abstract:
... Bees experience differences in thermal tolerance based on their geographical range; however, there are virtually no studies that examine how overwintering temperatures may influence immature survival rates. Here, we conducted a transplant experiment along an elevation gradient to test for climate‐change effects on immature overwinter survival using movement along elevational gradient for a communi ...

Abstract:
... Leaf longevity is an important adaptive strategy that allows plants to maximize photosynthetic carbon gain. Due to the difficulty of identifying overwintering bud scars and distinguishing the age sequence of twigs, leaf longevity is rarely studied in Cupressaceae species, which further limits our understanding of the leaf economic spectrum (LES) for these populations. Here, we investigated the lea ...

Abstract:
... The wood frog (Rana sylvatica) has adapted full-body freezing and thawing as a means of sub-zero winter survival and early-breeding in ephemeral pools. One such protective process implicated recently in freeze-thaw tolerance is that of anti-apoptotic signaling, which has been proposed to play a cytoprotective role by modulating stress-induced death signals. This study employed the use of immunoblo ...

Abstract:
... In most breeding programs of Macrobrachium rosenbergii, the candidate parents will go through an overwintering period of individual rearing stage (IRS) after the communal rearing stage (CRS). To study whether environmental differences affect the growth traits of candidate parents, the heritability (h²) and genotype by environment (G × E) interaction were estimated for harvest body weight (HBW) and ...

Abstract:
... Many insect species overwinter in various rock shelters (cavities and crevices), but the microclimates of rock biotopes remain poorly understood. We investigated the temperature dynamics in rock microhabitats where clusters of egg masses of the wintering spongy moth Lymantria dispar L. (SM) were observed. Our research objective was to find the relation between the ovipositing behaviour of females ...

Abstract:
... Fall dormancy is a vital component of alfalfa (Medicago sativa L.) yield in northern climates, but selection for the trait is often done at the expense of winter survival. We performed one cycle of selection to reduce fall dormancy in two winter hardy cultivars (Yellowhead and Peace) using a new indoor screening method. We compared the reduced dormancy populations with their respective initial cul ...

Abstract:
... Although some species of hornets spend enormous amounts of time constructing their nests, they only utilize the nest for one season and abandon it to overwinter in other habitats. Abandoned nests may be attractive habitats for other organisms to avoid predators and bad weather, but our knowledge of the organisms that make use of hornet nests for overwintering is very limited. Here, we examined the ...
