  29. <meta content="Crustose coralline algae (CCA) induce high rates of settlement and metamorphosis in a
  30. diversity of marine invertebrate larvae. It is often assumed that inducers associated with CCA are algal
  31. in origin, but an alternative hypothesis is that they originate from bacteria on the algal surface. Because
  32. many species manifest specificity in settling on CCA, a necessary condition of the hypothesis of
  33. bacterial origin is that bacterial assemblages on CCA are distinctive. Bacteria isolated from surfaces of 2
  34. South African species of CCA (Sporolithon sp. and Clathromorphum sp.), 2 seawater samples collected
  35. adjacent to the CCA, and ground-glass slides incubated next to the corallines were examined for 34
  36. morphological and physiological characters. Bacteria from the 2 CCA were distinct from those from
  37. other microhabitats and from each other, whereas isolates from the 2 seawater samples were similar,
  38. and those from glass slides were more similar to seawater populations than to coralline-associated
  39. bacteria. Bacteria from corallines were distinguished by narrower temperature ranges for growth, and in
  40. general, inability to (1) utilize glucose, (2) hydrolyse complex carbohydrates and urea, (3) utilize simple
  41. amino acids, and (4) reduce nitrate. These characteristics and the distributions of bacteria on crust
  42. surfaces suggest that epiphytic bacteria may utilise compounds from the algae for growth. Bacteria on
  43. Sporolithon sp. grew mostly from within recently damaged cells, whereas on Clathromorphum sp. they
  44. proliferated on a mucus-like matrix on its surface For some strains the association of bacteria with host
  45. alga may be specialised. These results are consistent with the hypothesis of bacterial origin of inducers
  46. associated with CCA, but they do not provide a critical test and thus do not resolve the question of algal
  47. or bacterial origin of inducers. In examining both hypotheses, we suggest methods to critically discern
  48. among these 2 alternatives. There was no trace of free GABA (y-aminobutyric acid) or L-DOPA (L-beta-3,4-
  49. dihydroxyphenylalanine) in cell-free extracts of either species of South African coralline algae or in
  50. bacteria isolated from the corallines and the other microhabitats. This finding supports other work
  51. suggesting that these compounds have no ecological relevance as inducers.

  423. diversity of marine invertebrate larvae. It is often assumed that inducers associated with CCA are algal
  424. in origin, but an alternative hypothesis is that they originate from bacteria on the algal surface. Because
  425. many species manifest specificity in settling on CCA, a necessary condition of the hypothesis of
  426. bacterial origin is that bacterial assemblages on CCA are distinctive. Bacteria isolated from surfaces of 2
  427. South African species of CCA (Sporolithon sp. and Clathromorphum sp.), 2 seawater samples collected
  428. adjacent to the CCA, and ground-glass slides incubated next to the corallines were examined for 34
  429. morphological and physiological characters. Bacteria from the 2 CCA were distinct from those from
  430. other microhabitats and from each other, whereas isolates from the 2 seawater samples were similar,
  431. and those from glass slides were more similar to seawater populations than to coralline-associated
  432. bacteria. Bacteria from corallines were distinguished by narrower temperature ranges for growth, and in
  433. general, inability to (1) utilize glucose, (2) hydrolyse complex carbohydrates and urea, (3) utilize simple
  434. amino acids, and (4) reduce nitrate. These characteristics and the distributions of bacteria on crust
  435. surfaces suggest that epiphytic bacteria may utilise compounds from the algae for growth. Bacteria on
  436. Sporolithon sp. grew mostly from within recently damaged cells, whereas on Clathromorphum sp. they
  437. proliferated on a mucus-like matrix on its surface For some strains the association of bacteria with host
  438. alga may be specialised. These results are consistent with the hypothesis of bacterial origin of inducers
  439. associated with CCA, but they do not provide a critical test and thus do not resolve the question of algal
  440. or bacterial origin of inducers. In examining both hypotheses, we suggest methods to critically discern
  441. among these 2 alternatives. There was no trace of free GABA (y-aminobutyric acid) or L-DOPA (L-beta-3,4-
  442. dihydroxyphenylalanine) in cell-free extracts of either species of South African coralline algae or in
  443. bacteria isolated from the corallines and the other microhabitats. This finding supports other work
  444. suggesting that these compounds have no ecological relevance as inducers.
