  3. Article ; Online: Dissecting the difference in tree species richness between Africa and South America.

    Abstract SignificanceOur full-scale comparison of Africa and South America's lowland tropical tree floras shows that both Africa and South America's moist and dry tree floras are organized similarly: plant families that are rich in tree species on one continent are also rich in tree species on the other continent, and these patterns hold across moist and dry environments. Moreover, we confirm that there is an important difference in tree species richness between the two continents, which is linked to a few families that are exceptionally diverse in South American moist forests, although dry formations also contribute to this difference. Plant families only present on one of the two continents do not contribute substantially to differences in tree species richness.

    Abstract Talbotiella gentii is a critically endangered caesalpiniaceous legume endemic to Ghana, restricted in distribution to the margins of the forest zone where there has been extensive fire damage in recent decades. It occurs as isolated, near-monospecific populations, some of which show little seedling regeneration. We studied its reproduction to determine limitations that might inform efforts to prevent its extinction. We report on flowering phenology, pollen dispersal and germination, fruit and seed set, seed size and germination, and seedling survival, using controlled and open pollination. Talbotiella gentii flowers profusely in most years. Although the flowers are coloured and scented, no animal pollinators were observed but pollen can be dispersed by wind. In open pollination, the number of pollen grains on stigmas and their germination was sufficient to fertilise the three ovules, despite competition from heavy stigmatic infestation by fungal spores and hyphae. Fruit set and seed set were low due to high flower losses and fruit abortion during development but ripe seeds showed high germination. Controlled pollination experiments (self, supplemented self, and intra- and inter-population crosses) showed that, while the species is self-compatible, selfing was the least successful treatment in all of the above steps of reproduction, whereas cross-pollination enhanced most steps, the more so for inter-population crosses. Seed size was notably greater in inter-population crosses and was positively correlated with genetic distance of the cross. The larger seeds associated with cross-pollination showed higher germination and seedling survival in the nursery. We conclude that limitations to natural reproduction in T. gentii are principally due to processes between pollen germination and fruit and seed set, including pollen quality (low genetic diversity and inbreeding), fertilisation rates, flower and fruit abortion, and resource limitation. Low seed size in open and self pollination may have implications for seedling establishment. Species fitness might be improved by introducing other genotypes to existing populations, but in situ protection of the populations is essential in the medium term.

  7. Article: Lianas may be favoured by low rainfall: evidence from Ghana

    Abstract We review the evidence in support of the hypotheses that (i) lianas are now increasing in tropical forests and (ii) lianas are more abundant in the drier tropical forests. There is good evidence to support both hypotheses, including a new analysis of data from Ghana. In this dataset, there is a linear increase in the percentage of species that are lianas, from 30% at a mean annual rainfall of 2,000 mm year-¹ to 43% at a mean annual rainfall of 1,000 mm year-¹. Both trends in lianas, one temporal, the other spatial, may be related to water availability, though parallel changes in canopy density (disturbance) may be contributory. It is also clear that most liana species in West Africa show restricted distribution along the rainfall gradient implying adaptation to different water availability. The reasons for the high sensitivity to rainfall may be that lianas have an especially effective water-transport system, with deep roots, large xylem vessels and a mechanism to avoid cavitation of water. As the climate of much of the tropics is becoming drier, we may expect increases in both liana abundance and their proportion in the flora over the future decades.

    Abstract We tested if logging enhances the recruitment of tree species by comparing young tree density in areas disturbed by logging with areas unaffected by logging 6 mo after logging in two Forest Reserves in Ghana. Analysis of 46 commercial timber species showed significantly higher postlogging recruitment in felling gaps and skid trails than in areas unaffected by logging. New seedlings substantially exceeded those lost due to logging operations. Species richness was significantly greater in areas disturbed by logging.

    Abstract Proliferation of lianas in canopy gaps can restrict tree regeneration in tropical forests through competition. Liana effects may differ between tree species, depending on tree requirements for above- and below-ground resources. We conducted an experiment in a shade house over 12 months to test the effect of light (7 and 27% external irradiance) on the competitive interactions between seedlings of one liana species and three tree species and the contribution of both above- and below-ground competition. Seedlings of the liana Acacia kamerunensis were grown with tree seedlings differing in shade tolerance: Nauclea diderrichii (Pioneer), Khaya anthotheca (Non-Pioneer Light Demander) and Garcinia afzelii (Non-Pioneer Shade Bearer). Trees were grown in four competition treatments with the liana: no competition, root competition, shoot competition and root and shoot competition. Both root and root-shoot competition significantly reduced relative growth rates in all three tree species. After one year, root-shoot competition reduced growth in biomass to 58% of those (all species) grown in no competition. The root competition treatment had a more important contribution in the effect of the liana on tree growth. Tree seedlings did not respond to competition with the liana by altering their patterns of biomass allocation. Although irradiance had a great effect on tree growth and allocation of biomass, the interaction between competition treatments and irradiance was not significant. Nauclea diderrichii, the tree species which responded most to the effects of competition, showed signs of being pot-bound, the stress of which may have augmented the competition effects. The understanding of the interaction of above- and below-ground competition between lianas and trees and its moderation by the light environment is important for a proper appreciation of the influence of lianas on tropical forest regeneration.
