  • Putative molt-inhibiting hormone in larvae of the shore crab Carcinus-maenas L. - an immunocytochemical approach
  • 1991
  • In: The Biological Bulletin. - Chicago : University of Chicago Press. - 0006-3185 .- 1939-8697. ; 180, s. 65-71
  • Journal article (peer-reviewed)abstract
    • Immunocytochemical investigations of the eyestalk of Carcinus maenas zoeal larval stages, using an antiserum directed against putative Carcinus molt-inhibiting hormone (MIH), revealed immunopositive neuronal structures. These structures included perikarya associated with the medulla terminalis X-organ, parts of the sinus gland tract, and the neurohemal organ-the sinus gland. Apart from an increase in volume of the sinus gland between zoeal stage I and II, no striking changes in the topography or morphology of the MIH neurosecretory system were observed. Immunopositive structures were found in similar locations to those seen in adult crabs. Our results suggest that the control of molting by MIH in crustacean larvae may be similar to the currently accepted model of molt control in adult decapod crustaceans.

  • Enhanced predation rates on cavity bird nests at deciduous forest edges : an experimental study
  • 1991
  • In: Ornis Fennica. - 0030-5685. ; 68:3, s. 93-98
  • Journal article (peer-reviewed)abstract
    • The size of a forest tract influences the composition of the fauna. If forests become fragmented this will affect the fauna in several ways. One of the main effects is enhanced nest predation. Several studies which confirm this effect have been carried out, but none has used natural cavities. I tested experimentally whether the predation rate was higher in natural tree-holes close to the forest/farmland edge than in the interior of the wood. In a fragmented deciduous forest, fresh Quail eggs were placed in natural cavities at various distances from the edge. The eggs were exposed during a period corresponding in length to the egg and nestling period of a hole-nesting bird. In the beginning of the period, the predation rate was higher close to the edge (< 20 m) than further inside the wood. This result may indicate that a predator first searches the ecotone and afterwards penetrates deeper inside the forest. The results is in accord with earliest observations than nests in natural cavities seem to be less vulnerable than other types of nests.
