Abstract Background The key to fishery management is knowing the appropriate
reproductive strategies of the targeted fish. For most gobiid species, the
iteroparous pattern is dominant compared to semelparity. Albeit Butis
koilomatodon plays an important role in the Mekong Delta’s food supply, its
reproductive biological data have not been known. Hence, this study was
conducted to provide new funda... hiện toàn bộ
Abstract Background The mechanism by which sea anemones attach to surfaces
underwater remains elusive, which is surprising given their ubiquitous
distribution in the world’s oceans and tractability for experimental biology.
Their adhesion is mechanically interesting, bridging the interface between very
hard and soft materials. The Cnidaria are thought to have evolved adhesion to
surfaces at least ... hiện toàn bộ

Abstract Background Rodents are thought to be produced their human-audible calls
(AUDs, below 20 kHz) with phonation mechanism based on vibration of the vocal
folds, whereas their ultrasonic vocalizations (USVs, over 20 kHz) are produced
with aerodynamic whistle mechanism. Despite of different production mechanisms,
the acoustic parameters (duration and fundamental frequency) of AUDs and USVs
chan... hiện toàn bộ

Abstract Background Natural enemy abundance in a crop plot depends on its prey
presence and also influenced by habitats close to field. Landscape changes are
also important factors driving pest and natural enemy population abundance in a
specific crop field. Examining these kinds of effects on insect pests or
biocontrol agents, as well as analysis of their functional food webs, would be
asset to m... hiện toàn bộ

AbstractBackgroundIntrasexual competition over access to resources can lead to
aggression between individuals. Because overt aggression, i.e. fights, can be
costly for contestants, the communication of aggressive motivation prior to
engagement in a physical fight is often mediated by conventional signals.
Animals of various taxa, including fishes, display visual signals such as body
coloration tha... hiện toàn bộ
Abstract Background Most temperate bats are regular hibernators in the winter.
Knowledge about the length of their active season and how they adjust their
nightly activity throughout the season, is critical to conservation. The
characteristics of these are likely to vary with climate as well as latitude.

Pipistrellus pygmaeus i... hiện toàn bộ

AbstractBackgroundPostcopulatory mate choice occurs ubiquitously in the animal
kingdom. However, it is usually a major challenge to visualise the process
taking place in a body. This fact makes it difficult to understand the
mechanisms of the process. By focusing on the shape of female sperm storage
organs (spermathecae), we aimed to elucidate their functional morphology using
six representative b... hiện toàn bộ
