Clues on an intraspecific communication system in seed-seedling transition
(Wiley-Blackwell, 2021-03-14)
How much interactivity is in a seed-seedling transition system? We hypothesize that seed-seed, seed-seedling, and seedling-seedling interactions can drive the early plant development in artificial growth systems directly ...
Getting ready for mating: The importance of male touching as an accelerator of ovarian growth in a caridean shrimp
(Elsevier Gmbh, 2018-10)
The present study was aimed at evaluating the effect of male presence on ovarian maturation in juvenile females and the role of potential chemical, visual and tactile cues emitted by males in that physiological process. A ...
Geographic variation in the laryngeal morphology of a widely distributed South-American anuran: behavioural and evolutionary implications
(Oxford University Press, 2020)
Sound-producing organs generate acoustic signals that have a fundamental role in communication systems. In species exhibiting different biogeographic patterns, variations of these structures can explain a large part of ...
Mechanism of the wing colouration in the dragonfly Zenithoptera lanei (Odonata: Libellulidae) and its role in intraspecific communication
(Elsevier B.V., 2015-10-01)
Zenithoptera dragonflies are known for their remarkable bluish colouration on their wings and unique male behaviour of folding and unfolding their wings while perching. However, nothing is known about the optical properties ...
Mandibular gland secretions of meliponine worker bees: further evidence for their role in interspecific and intraspecific defence and aggression and against their role in food source signalling
(COMPANY OF BIOLOGISTS LTD, 2009)
Like ants and termites some species of stingless bees (Meliponini), which are very important pollinators in the tropics, use pheromone trails to communicate the location of a food source. We present data on the communicative ...
Sophisticated Communication in the Brazilian Torrent Frog Hylodes japi
(Public Library Science, 2016-01-13)
Intraspecific communication in frogs plays an important role in the recognition of conspecifics in general and of potential rivals or mates in particular and therefore with relevant consequences for pre-zygotic reproductive ...
Capybara social structure and dispersal patterns: Variations on a theme
(Alliance Communications Group Division Allen Press, 2011-02)
Capybaras, (Hydrochoerus hydrochaeris) are large, herbivorous New World hystricomorphs, common in the seasonally flooded savannas of tropical and subtropical South America. In this paper we review the social structure and ...
Visual and acoustic communication in the Brazilian torrent frog, Hylodes asper (Anura : Leptodactylidae)
(Herpetologists League, 1999-09-01)
We studied the signaling, territorial, and courtship behaviors of the diurnal frog Hylodes asper. Visual and acoustic communication were used during intraspecific interactions involving males, females. and subadults. Hylodes ...
