Dangerous visions: a review of visual antipredator strategies in spiders
Evolutionary Ecology - Tập 36 - Trang 163-180 - 2022
Many animals use visual traits as a predator defence. Understanding these visual traits from the perspective of predators is critical in generating new insights about predator–prey interactions. In this paper, we propose a novel framework to support the study of strategies that exploit the visual system of predators. With spiders as our model taxon, we contextualise these strategies using two orth...... hiện toàn bộ
Adult female hamsters require long and sustained exposures to heterospecific males to avoid interspecific mating
Evolutionary Ecology - Tập 25 - Trang 391-401 - 2010
Interspecific mating normally decreases female fitness. In many species, females avoid heterospecific males innately or by imprinting on their parents. Alternatively, adult females could learn to discriminate against heterospecific males after exposure to such males. For example, Syrian hamster (Mesocricetus auratus) females learn to discriminate between conspecific males and Turkish hamster (M. b...... hiện toàn bộ
Lịch sử tiến hóa và giới tính là những yếu tố quan trọng ảnh hưởng đến nhân khẩu học của tôm hùm trong hệ sinh thái hang động hạn chế tài nguyên Dịch bởi AI
Evolutionary Ecology - Tập 34 - Trang 235-255 - 2019
Các loài động vật sống phụ thuộc và không phụ thuộc vào hang động đều chơi những vai trò chức năng quan trọng trong hệ sinh thái hang động. Khác với các loài động vật sống phụ thuộc vào hang, các loài động vật sống không phụ thuộc vào hang có thể tồn tại trong cả các môi trường bên trong và bên ngoài hang động. Tuy nhiên, chưa có mô hình nhân khẩu học so sánh nào giải thích sự hiện diện kéo dài củ...... hiện toàn bộ

Genetic variation for shell traits in a direct-developing marine snail involved in a putative sympatric ecological speciation process
Evolutionary Ecology - Tập 21 - Trang 635-650 - 2006
Populations of the marine gastropod Littorina saxatilis from exposed rocky shores of NW Spain provide one of the few putative cases of sympatric ecological speciation. Two ecotypes with large differences in shell morphology and strong assortative mating are living at different vertical levels of the shore separated by a few meters. It has been hypothesized that shell size is the main determinant f...... hiện toàn bộ
A hypothesis for the evolution of androdioecy: the joint influence of reproductive assurance and local mate competition in a metapopulation
Evolutionary Ecology - Tập 14 - Trang 195-211 - 2000
In a subdivided population with recurrent local extinction and re-colonisation, competition amongst related pollen or sperm to fertilise ovules or eggs (‘local mate competition’) is expected to select for female-biased sex allocation. Population turnover should also select against unisexuality in favour of self-fertile cosexuality, because males and females are unable to establish new populations ...... hiện toàn bộ
Pathogen persistence in migratory insects: high levels of vertically-transmitted virus infection in field populations of the African armyworm
Evolutionary Ecology - - 2009
Pathogens face numerous challenges to persist in hosts with low or unpredictable population densities. Strategies include horizontal transmission, such as by the production of propagules that persist in the environment, and vertical transmission from adults to offspring. While many pathogens are capable of horizontal and vertical transmission little is known of their relative roles under realistic...... hiện toàn bộ
Pollination intensity and nutrient availability interactively shape directional selection on flower size in an orchid herb
Evolutionary Ecology - Tập 37 - Trang 721-734 - 2023
Quantifying the importance of pollination intensity and nutrient availability in influencing phenotypic selection on floral traits is an essential step to understanding floral evolutionary responses in complex environments. We quantified phenotypic selection on four floral traits (flowering start date, angle between adjacent flowers, corolla size and number of flowers) in Spiranthes sinensis by ma...... hiện toàn bộ
Predation impacts brain allometry in female guppies (Poecilia reticulata)
Evolutionary Ecology - Tập 36 - Trang 1045-1059 - 2022
Cognitive and sensory abilities are vital in affecting survival under predation risk, leading to selection on brain anatomy. However, how exactly predation and brain evolution are linked has not yet been resolved, as current empirical evidence is inconclusive. This may be due to predation pressure having different effects across life stages and/or due to confounding factors in ecological compariso...... hiện toàn bộ
