Antagonistic interactions between predator and prey: mobbing of jaguars (Panthera onca) by white-lipped peccaries (Tayassu pecari)
Springer Science and Business Media LLC - Tập 23 - Trang 45-48 - 2020
Lilian E. Rampim, Leonardo R. Sartorello, Carlos E. Fragoso, Mario Haberfeld, Allison L. Devlin
Ambush predators rely on stealth to successfully secure prey. Mobbing is a rarely observed anti-predation strategy used by group-living prey species whereby several individuals distract or harass a predator until it either ends the pursuit or leaves the area. Herein, we present three unique cases of white-lipped peccaries (Tayassu pecari) mobbing jaguars (Panthera onca) in the wild. White-lipped p...... hiện toàn bộ
Differences in locomotor performances between two sympatric species of freshwater turtles
Springer Science and Business Media LLC - Tập 26 - Trang 133-137 - 2023
Ana Golubović, Vukašin Bjelica, Ana Štih Koren
Animals whose ecological niches largely overlap within a habitat can get into intra-specific and/or inter-specific competition for some of the limited resources available. We hypothesise that differences in locomotor abilities might be a key component deciding which individual will gain the resource, especially in animals with limited agility, such as turtles. To address this hypothesis, we tested...... hiện toàn bộ

The environment matters: season and female contact affect the behavior of captive Addax nasomaculatus male antelope
Springer Science and Business Media LLC - Tập 26 - Trang 109-117 - 2023
Matías Villagrán, Mariana Ceva, Ariane Machiñena, Mariana Perdomo, Lucas Berro, Cesar Echaides, Juan Pablo Damián
The addax antelope (Addax nasomaculatus) is a species under serious threat of extinction, as it is more abundant in captivity than in the wild. However, little is known about its basic biology. The aims of this study were to determine how locomotor, feeding, aggressive, marking, and sexual behavior of male addax allocated in all-male groups vary with season and with female contact (i.e., biostimul...... hiện toàn bộ
Does acoustic environment modify boldness and related life-history traits in field cricket nymphs?
Springer Science and Business Media LLC - Tập 22 Số 2 - Trang 105-112 - 2019

Examination of boldness traits in sexual and asexual mollies (Poecilia latipinna, P. formosa)
Springer Science and Business Media LLC - Tập 14 - Trang 77-83 - 2011
Kristin Scharnweber, Martin Plath, Michael Tobler
Considering the high costs of sexual reproduction (e.g., the production of males), its maintenance and predominance throughout the Animal Kingdom remain elusive. Especially the mechanisms allowing for a stable coexistence of closely related sexual and asexual species are still subject to a lively debate. Asexuals should rapidly outnumber sexuals due to higher population growth rates, unless they f...... hiện toàn bộ
Temporal polyethism, life expectancy, and entropy of workers of the ant Ectatomma vizottoi Almeida, 1987 (Formicidae: Ectatomminae)
Springer Science and Business Media LLC - Tập 13 - Trang 23-31 - 2010
Alexsandro Santana Vieira, Wedson Desidério Fernandes, William Fernando Antonialli-Junior
We investigated the changes in the behavioral repertoire over the course of life and determined the life expectancy and entropy of workers of the ant Ectatomma vizottoi. Newly emerged ants were individually marked with model airplane paint for observation of behaviors and determination of the age and life expectancy. Ants were divided into two groups: young and old workers. The 36 behaviors observ...... hiện toàn bộ
Body size and group size of Cuban tree frog (Osteopilus septentrionalis) tadpoles influence their escape behaviour

Siberian crane duet as an individual signature of a pair: comparison of visual and statistical classification techniques
Springer Science and Business Media LLC - Tập 13 - Trang 39-48 - 2010
Eugenia V. Bragina, Irina R. Beme
Vocal individuality varies between species and/or ontogenesis stages depending on needs in the vocal recognition, but also estimation of individual differences depends on the method of analysis. We studied pair-specific differences of duets elicited by mating pairs of Siberian crane Grus leucogeranus. We quantitatively described the duet structure and compared visual and statistical classification...... hiện toàn bộ
