Predation risk and floral rewards: How pollinators balance these conflicts and the consequences on plant fitness [0.03%]
捕食风险与花蜜奖励：传粉者如何在其中权衡取舍及其对植物适应度的影响
Sabrina S Gavini,Carolina Quintero

Foraging behavior of pollinators is shaped by, among other factors, the conflict between maximizing resource intake and minimizing predation risk; yet, empirical studies quantifying variation in both forces are rare, compared to those inves...
Cognitive abilities related to foraging behavior in Vespula vulgaris (Hymenoptera: Vespidae) [0.03%]

Vespula vulgaris is an invasive social wasp that has become established in many parts of the world. Plastic cognitive systems are expected to be advantageous for invasive species, given that they continuously face dynamic and unpredictable ...
A conserved pheromone receptor in the American and the Asian palm weevils is also activated by host plant volatiles [0.03%]
美洲棕象甲和亚洲棕象甲中一个保守的聚集信息素受体也可以被寄主植物挥发物激活

The evolution of chemosensory receptors is key for the adaptation of animals to their environment. Recent knowledge acquired on the tri-dimensional structure of insect odorant receptors makes it possible to study the link between modificati...
Acclimation temperature influences the thermal sensitivity of injury accumulation in Folsomia candida at extreme low and high temperatures [0.03%]
适应温度影响了极端低温和高温下费尔索米亚 Candida 损伤积累的热敏性

Micha Wehrli et al.
The importance of thermal acclimation for the Thermal Death Time (TDT) landscape of the common soil living springtail, Folsomia candida (Collembola, Isotomidae), was investigated. To this aim, we acclimated adult springtails at 10 °C (cold...
Dehydration and tomato spotted wilt virus infection combine to alter feeding and survival parameters for the western flower thrips, Frankliniella occidentalis [0.03%]
缺水和番茄斑萎病毒对西花蓟马取食及存活的影响

Samuel T Bailey et al.
Dehydration and tomato spotted wilt virus (TSWV) infection substantially impact the feeding of western flower thrips, Frankliniella occidentalis. Until now, the dynamics between these biotic and abiotic stresses have not been examined for t...

Insects have spread across diverse ecological niches, including extreme environments requiring specialized traits for survival. However, little is understood about the reproductive traits required to facilitate persistence in such environme...
Bet-hedging in parasitoids: when optimization is not the best strategy to cope with climatic extremes [0.03%]
寄生虫的下注策略：在应对气候极端事件时非最优策略可能是最佳选择
Joan van Baaren,Guy Boivin,Bertanne Visser et al.
Joan van Baaren et al.
Bet-hedging occurs when unreliable environments select for genotypes exhibiting a lower variance in fitness at the cost of a lower mean fitness for each batch of progeny. This means that at the level of the genotype, the production of mostl...
Effect of a severe cold spell on overwintering survival of an invasive forest insect pest [0.03%]
一次严重的寒潮对一种入侵森林害虫越冬存活的影响

Chris J K MacQuarrie et al.
Cold temperatures can play a significant role in the range and impact of pest insects. Severe cold events can reduce the size of insect outbreaks and perhaps even cause outbreaks to end. Measuring the precise impact of cold events, however,...
Diet specialization mediates drivers of Cucurbita herbivory in a semi-arid agroecosystem [0.03%]
饮食专化介导了半干旱农业生态系统中瓜类植物受害虫侵害的驱动因素
Hannah L Gray,Nicholas A Ivers,Elizabeth Lopez et al.
Hannah L Gray et al.
Herbivory is a major fitness pressure for plants and a key driver of crop losses in agroecosystems. Dense monocultures are expected to favor specialist herbivorous insects, particularly those who primarily consume crop species; yet, levels ...
Stronger interspecific sexual differences may be favored when females search for mates in the presence of congeners [0.03%]
当雌性在同种存在的情况下寻找配偶时，较强的种内性别差异可能更受青睐

Alaine C Hippee et al.
Why are some species sexually dimorphic while other closely related species are not? While all females in genus Strauzia share a multiply-banded wing pattern typical of many other true fruit flies, males of four species have noticeably elon...
