Sexual dimorphism is a common phenomenon in the animal kingdom. To test the
consistency of sexual dimorphism patterns among sympatric species of the same genus, ten …

Variations in morphological characteristics are frequently important determinants of the
physiology, ecology and inter-and intra-specific interactions of organisms. Various causative …

Concern about the impacts of invasive species on invaded communities is often linked to the
expectation that invasive consumers will be more effective at using resources than native …

Fiddler crabs (Uca) are ecosystem engineers in coastal ecosystems. Many anthropogenic
and natural factors can affect the time allocated to various behaviours in Uca. However, the …

Understanding population dynamics requires knowledge of reproductive aspects such as
sexual maturity, fertility, and growth changes of body components. We analyzed the relative …

We investigated the amount of time that large and small, male and female fiddler crabs Uca
annulipes (H. Milne Edwards, 1837) spent on feeding, walking, standing, grooming …

Many animals show sexually divergent foraging behaviours reflecting different physiological
constraints or energetic needs. We used a bioenergetics approach to examine sex …

The predation of commercially important Japanese sea cucumber Apostichopus japonicus
by the kelp crab Pugettia ferox, widely distributed in coastal northeast Asia, was examined in …

In this study we determined the benefits of building chimneys in Uca rosea (Tweedie, 1937).
We predicted that (1) burrows with chimneys (ie,“chimneys”) would decrease intruder …

We examined the effects of population density on body size and burrow characteristics of
Uca bengali Crane,. We predicted that (1) males in high-density areas (HD) should be larger …
