Differential effects of larval and adult nutrition on female survival, fecundity, and size of the yellow fever mosquito, Aedes aegypti
Frontiers in Zoology - Tập 18 - Trang 1-9 - 2021
The yellow fever mosquito, Aedes aegypti, is the principal vector of medically-important infectious viruses that cause severe illness such as dengue fever, yellow fever and Zika. The transmission potential of mosquitoes for these arboviruses is largely shaped by their life history traits, such as size, survival and fecundity. These life history traits, to some degree, depend on environmental condi......
Control of social monogamy through aggression in a hermaphroditic shrimp
Frontiers in Zoology - Tập 8 - Trang 1-7 - 2011
Sex allocation theory predicts that in small mating groups simultaneous hermaphroditism is the optimal form of gender expression. Under these conditions, male allocation is predicted to be very low and overall per-capita reproductive output maximal. This is particularly true for individuals that live in pairs, but monogamy is highly susceptible to cheating by both partners. However, certain condit......
Goats distinguish between positive and negative emotion-linked vocalisations
Frontiers in Zoology - Tập 16 - Trang 1-11 - 2019
Evidence from humans suggests that the expression of emotions can regulate social interactions and promote coordination within a group. Despite its evolutionary importance, social communication of emotions in non-human animals is still not well understood. Here, we combine behavioural and physiological measures, to determine if animals can distinguish between vocalisations linked to different emot......
When SEM becomes a deceptive tool of analysis: the unexpected discovery of epidermal glands with stalked ducts on the ultimate legs of geophilomorph centipedes
Frontiers in Zoology - Tập 18 - Trang 1-19 - 2021
The jointed appendage is a key novelty in arthropod evolution and arthropod legs are known to vary enormously in relation to function. Among centipedes, the ultimate legs always are distinctly different from locomotory legs, and different centipede taxa evolved different structural and functional modifications. In Geophilomorpha (soil centipedes), ultimate legs do not participate in locomotion and......
Behavioral and physiological female responses to male sex ratio bias in a pond-breeding amphibian
Frontiers in Zoology - Tập 9 - Trang 1-10 - 2012
The phenomenon of sexual conflict has been well documented, and in populations with biased operational sex ratios the consequences for the rarer sex can be severe. Females are typically a limited resource and males often evolve aggressive mating behaviors, which can improve individual fitness for the male while negatively impacting female condition and fitness. In response, females can adjust thei......
Different feeding strategies in Antarctic scavenging amphipods and their implications for colonisation success in times of retreating glaciers
Frontiers in Zoology - Tập 14 - Trang 1-15 - 2017
Scavenger guilds are composed of a variety of species, co-existing in the same habitat and sharing the same niche in the food web. Niche partitioning among them can manifest in different feeding strategies, e.g. during carcass feeding. In the bentho-pelagic realm of the Southern Ocean, scavenging amphipods (Lysianassoidea) are ubiquitous and occupy a central role in decomposition processes. Here w......
Influences of submerged plant collapse on diet composition, breadth, and overlap among four crane species at Poyang Lake, China
Frontiers in Zoology - Tập 18 - Trang 1-17 - 2021
Interannual variation in resource abundance has become more unpredictable, and food shortages have increasingly occurred in the recent decades. However, compared to seasonal fluctuations in resource abundance, the influences of interannual variation in resource abundance on the dietary niches of consumers remain poorly understood. Poyang Lake, China, is a very important wintering ground for the gl......
Hướng tới thư viện mã vạch toàn diện cho đời sống Bắc cực - Ephemeroptera, Plecoptera và Trichoptera của Churchill, Manitoba, Canada Dịch bởi AI
Frontiers in Zoology - Tập 6 - Trang 1-9 - 2009
Nghiên cứu này báo cáo tiến trình trong việc xây dựng thư viện tham chiếu mã vạch DNA cho các nhóm Ephemeroptera, Plecoptera và Trichoptera ("EPTs") từ một địa điểm cận Bắc cực của Canada, nơi đang được tiến hành một cuộc điều tra đa dạng sinh học toàn diện bằng phương pháp mã vạch DNA. Ba nhóm côn trùng thủy sinh này thể hiện mức độ đa dạng loài vừa phải, làm cho chúng trở thành đối tượng lý tưởn......

Modeling the origins of mammalian sociality: moderate evidence for matrilineal signatures in mouse lemur vocalizations
Frontiers in Zoology - Tập 11 - Trang 1-14 - 2014
Maternal kin selection is a driving force in the evolution of mammalian social complexity and it requires that kin are distinctive from nonkin. The transition from the ancestral state of asociality to the derived state of complex social groups is thought to have occurred via solitary foraging, in which individuals forage alone, but, unlike the asocial ancestors, maintain dispersed social networks ......
Fecal sacs attract insects to the nest and provoke an activation of the immune system of nestlings
Frontiers in Zoology - Tập 13 - Trang 1-9 - 2016
Nest sanitation is a widespread but rarely studied behavior in birds. The most common form of nest sanitation behavior, the removal of nestling feces, has focused the discussion about which selective pressures determine this behavior. The parasitism hypothesis, which states that nestling fecal sacs attract parasites that negatively affect breeding birds, was proposed 40 years ago and is frequently......
