“…Reusch (2003) found reduced seed-set after experimental reduction in flowering shoots of the monoecious Zostera marina, this being the only recorded experimental evidence of pollen limitation in a hydrophilous plant. Vermaat et al (2004) reported decreased fruit development in fragmented habitats of the dioecious surface-pollinated Enhalus acoroides.…”

Pollen limitation is relatively common in plants pollinated by animals, but whether pollen availability may limit the reproduction of water-pollinated plants is much less known. We investigated pollen production and possible limitation of pollen availability in the hydrophilous dioecious seagrass Thalassia testudinum in an area where flowering was abundant (20 to 33% of the shoots produced flowers annually). Fruit production decreased from 86 to 60% after experimental removal of half of the male flowers (estimated pollen:ovule ratio of 6.7 × 10 4 :1) during April 2008. In late April to May 2009, when male flowers were less abundant than in the previous year (at a pollen:ovule ratio of 3.7 × 10 4 :1), artificial pollination resulted in an increase in fruit production from 65% in control flowers to 91% in the treated flowers in the same plot. This study is the first experimental evidence of pollen limitation in a dioecious plant with hydrophilous pollination.

“…In fact, several studies have shown that seagrass habitats are declining worldwide due to anthropogenic disturbances, such as eutrophication, climate change, habitat disruption and fragmentation, water turbidity, pollutants, coastal develop ment, and introduced species in the meadows (e.g., Haynes et al, 2000;Hauxwell and Valiela, 2004;Vermaat et al, 2004;Foden, 2007;Williams, 2007;Ostoich et al, 2009;Montefalcone et al, 2010). Additionally, seagrasses are often simultaneously influenced by multiple stressors at different temporal and spatial scales, namely environmental (stochastic meteorological and hydrological conditions) and biological factors (Orth et al, 2006a;Burkholder et al, 2007).…”

“…With greater fragmentation the likelihood of a rhizome being sufficiently proximate to the damaged area to facilitate recovery is reduced. Secondly a fragmented meadow may have reduced sexual reproductive output (Cabaco and Santos, 2012;Vermaat et al, 2004).…”

Seagrass ecosystems represent a global marine resource that is declining across its range. To halt degradation and promote recovery over large scales, management requires a radical change in emphasis and application that seeks to enhance seagrass ecosystem resilience. In this review we examine how the resilience of seagrass ecosystems is becoming compromised by a range of local to global stressors, resulting in ecological regime shifts that undermine the long-term viability of these productive ecosystems. To examine regime shifts and the management actions that can influence this phenomenon we present a conceptual model of resilience in seagrass ecosystems. The model is founded on a series of features and modifiers that act as interacting influences upon seagrass ecosystem resilience. Improved understanding and appreciation of the factors and modifiers that govern resilience in seagrass ecosystems can be utilised to support much needed evidence based management of a vital natural resource.
