Ritualized male–male combat resulting from intraspecific food competition in three Agkistrodon species J. Ethol. (IF 0.9) Pub Date : 2024-03-17
Abstract Male–male combat occurs in many snake species and is often thought to result from competition for mates. We argue a more thorough assessment of the contexts in which combat occurs is warranted for snakes. We made field video observations of Agkistrodon conanti in central Florida, A. piscivorus in eastern North Carolina, and A. contortrix in eastern Kentucky. These observations were made in

Host preference of a symbiotic flatworm and its response to conspecific and host mucus J. Ethol. (IF 0.9) Pub Date : 2023-12-23
Abstract Mucus-mediated communication plays a significant role in shaping community dynamics, particularly in marine organisms found in intertidal zones with complex topography. In this study, we investigated the host preference of a flatworm Stylochoplana pusilla, which lives symbiotically with intertidal gastropods, and its responses to the host and conspecific mucus. Our line transect surveys revealed

Social play and affiliation as possible coping strategies in a group of Maremmana beef cattle J. Ethol. (IF 0.9) Pub Date : 2023-12-15
Abstract Animal internal states can be expressed via social behaviors that are known to shape group dynamics (i.e., allogrooming, social play, agonistic encounters) and that can be flexibly used after experiencing negative stimuli. In extensively bred domestic species, animals are not always used to human handling, and thus also mandatory health checks can alter group dynamics. Here, we investigated

Protogynous sex change has been widely reported as a life-history strategy in polygynous reef fish. Dascyllus reticulatus is known to form haremic colonial groups on branching corals and is thought to undergo protogynous sex change based on gonad histology. We conducted a 2-year underwater survey on 13 haremic groups to examine the sex-change patterns of D. reticulatus on reefs of southern Japan. We

Antibiotics affect migratory restlessness orientation J. Ethol. (IF 0.9) Pub Date : 2022-03-10 Yuval Werber, Eviatar Natan, Yizhar Lavner, Yoni Vortman
The role of microbiome in shaping animal’s behavior is well established. Accordingly, the use of antibiotics may have profound effects on behavior, which are seldom examined. Recently, the symbiotic magnetic-sensing hypothesis has been forwarded as a mechanistic explanation for the phenomenon of animal magnetoreception. It suggests a symbiotic relationship between magnetotactic bacteria (MTB) and the

Reproductive behavior of endangered spined loach Cobitis magnostriata in the field J. Ethol. (IF 0.9) Pub Date : 2022-02-25 Kiyohito Morii, Koh-Ichi Takakura
Spined loaches, Cobitis spp., have been studied in broad fields of research. Particularly, this taxon has attracted attention because of sexual interactions, such as reproductive interference and hybrid speciation, among species. Nevertheless, knowledge of the reproductive behaviors of this genus has been limited to findings from visual observations of aquarium-resident individuals. For this study

Nocturnal light-specific temporal partitioning facilitates coexistence for a small mesopredator, the eastern spotted skunk J. Ethol. (IF 0.9) Pub Date : 2022-02-16 Courtney J. Marneweck, Cameron R. Forehand, Charles D. Waggy, Stephen N. Harris, Todd E. Katzner, David S. Jachowski
Eastern spotted skunks are of conservation concern, where competition and predation are possible causes of their decline. Using camera traps at a food subsidy, we investigated nocturnal temporal overlap of spotted skunks with co-occurring predators. Spotted skunks were more active during dark nights, when their activity overlapped with the largest predator (coyotes), but not with other mesopredators

Predation strategy of the brown widow spider Latrodectus geometricus Koch, 1841 against prey with different defensive mechanisms J. Ethol. (IF 0.9) Pub Date : 2022-01-27 Luiza E. A. Gonzaga, Renato P. Salomão, Geraldo J. B. Moura, André F. A. Lira
Predators, such as spiders, may modulate their predatory behavior according to the defensive mechanisms of their prey. This study analyzed the prey capture behavior of Latrodectus geometricus spiders, specifically through the parameter’s acceptance of the prey, immobilization time, and bitten areas. A total of 80 adult female spiders were used, and they were fed cockroach nymphs and fasted for seven

The black-legged tick –sometimes referred to as the deer tick—Ixodes scapularis and the lone star tick Ambylomma americanum are sympatric species whose distributions overlap both geographically and ecologically. Each species vectors a number of pathogens including the agents responsible for Lyme disease and ehrlichioses. We performed ethological observations of both species in five behavioral arenas

Behavioral patterns that determine the mating rates in a wing dimorphic riffle bug, Microvelia horvathi Lundblad, 1933 (Hemiptera: Heteroptera: Veliidae) J. Ethol. (IF 0.9) Pub Date : 2022-01-17 Ryosuke Matsushima, Tomoyuki Yokoi
Wing dimorphic insects are known to be a well-established model of the trade-off between flight capability and reproduction. Macropterous morph expends its energy for developing and maintaining the flight apparatus at the expense of reproduction, while apterous morphs have greater reproductive output. Mating rates of apterous morph tend to be higher than those of macropterous, especially in early adulthood

Lack of discrimination of sex and maturity of conspecifics in the copulation attempts of the male stalk-eyed fly, Sphyracephala detrahens (Diptera: Diopsidae) J. Ethol. (IF 0.9) Pub Date : 2022-01-13 Kudo, Ayumi, Fujii, Takeshi, Ishikawa, Yukio
Among insects, males have evolved the ability to discriminate potential mates to avoid vain mating attempts. In Diptera, courtship and mating behaviors of species that do not discriminate potential mates have rarely been studied. In this study, we investigated copulation attempts of the stalk-eyed fly, Sphyracephala detrahens males, which do not engage in any observable pre-copulatory courtship behavior

Encounter with heavier females changes courtship and fighting efforts of male field crickets Gryllus bimaculatus (Orthoptera: Gryllidae) J. Ethol. (IF 0.9) Pub Date : 2022-01-04 Kuriwada, Takashi
The effects of mating experience on male mating behavior are mediated by four factors: mating cost, such as resource depletion, perception of mating opportunities, self-perception of attractiveness, and female quality. For example, encountering females might increase male expectations of prospective mating opportunities, while copulation increases self-perception of attractiveness in males. To determine
