The energetic cost of agnostic behaviour in the velvet swimming crab, Necora(=Liocarcinus) puber (L.)
Article Abstract:
A study exploring the energy costs involved in agonistic behavior in the velvet swimming crab was conducted. Results indicate a linear relationship in the consumption of oxygen and the rate of scaphognathite beating. The amount of beating and oxygen consumption escalated with an increase in the level of intensity and duration of agonistic behavior. Recovery from respiratory activity sometimes was prolonged. There was no significant difference between energy consumption and winning or losing.

Male body size and paternal behavior in smallmouth bass, Micropterus dolomieui (Pisces: Centrachidae)
Article Abstract:
The parental behavior of nesting male Micropterus dolomieui was investigated to determine whether male body size provided females with an indicator of the level of care males would provide their progeny. The results showed a higher reproduction-independent mortality among large parental males, thus indicating a higher absolute investment into current offspring. It is suggested that this higher absolute investment may be the reason for females' apparent preference for large male M. dolomieui.

Effects of body size on agnostic encounters between male jumping spiders (Araneae: Salticidae)
Article Abstract:
A study exploring the effects of body size on agonistic encounters between male jumping spiders was conducted. Results indicate that increased body size is a major determinant in the conclusion of an encounter and in the escalation of the conflict. Heavier specimens increasedthe level of intensity to the maximum level almost immediately. Subsequently, the heavier spiders won more.
