“…The distances that biological vectors transport seagrass material ranges from metres to 1000 km. Invertebrates facilitate pollen movement for Thalassia over metres [ 17 ]. Birds have moved vegetative fragments and seeds of Ruppia and Zostera over hundreds of kilometres potentially across continents, and fishes (200 m) and turtles (up to 1.5 km) have moved Zostera seeds significant distances [ 19 ].…”

The movement ecology of seagrasses

A movement ecology framework is applied to enhance our understanding of the causes, mechanisms and consequences of movement in seagrasses: marine, clonal, flowering plants. Four life-history stages of seagrasses can move: pollen, sexual propagules, vegetative fragments and the spread of individuals through clonal growth. Movement occurs on the water surface, in the water column, on or in the sediment, via animal vectors and through spreading clones. A capacity for long-distance dispersal and demographic connectivity over multiple timeframes is the novel feature of the movement ecology of seagrasses with significant evolutionary and ecological consequences. The space–time movement footprint of different life-history stages varies. For example, the distance moved by reproductive propagules and vegetative expansion via clonal growth is similar, but the timescales range exponentially, from hours to months or centuries to millennia, respectively. Consequently, environmental factors and key traits that interact to influence movement also operate on vastly different spatial and temporal scales. Six key future research areas have been identified.

“…The existing records of isopods for the Mexican Caribbean coast combined account for 51 species (Markham et al 1990;Barriga and Briones 1992;CamposVázquez 2000;van Tussenbroek and Brearley 1998;van Tussenbroek et al 2012), but with our new records, the total number rises to 70 species. This number is likely to increase in the near future as the results of several ongoing investigations become available.…”

“…Campos-Vázquez (2000) collected crustaceans associated with macroalgae in Bajo Pepito, Isla Mujeres, Mexican Caribbean and found Isopoda to be the most abundant group and eight species were identified. Van Tussenbroek et al (2012) investigated meso-faunal invertebrates visiting male and female flowers of the seagrass Thalassia testudinum at night in the Puerto Morelos reef lagoon, on 76 flowers they found 57 species of crustaceans, eight of them isopods, including two new records.…”

New records of isopods (Crustacea: Peracarida: Isopoda) from the Mesoamerican Reef at Puerto Morelos, Quintana Roo, Mexico

New distribution records are presented for 19 species of isopods that are recorded for the Mexican Caribbean coast for the first time. The sampling program was conducted in three sites and at three different depths in each site within the Arrecife de Puerto Morelos Nature Reserve. The new records belong to 10 families and 15 genera in the suborders Asellota, Cymothoida and Sphaeromatidea. With the new records included herein isopods could be the most diverse group of peracarid crustaceans found in the Puerto Morelos Reef.

“…Pollen and seeds both drift within the water column, within and between meadows. Although pollination of seagrass flowers has previously been thought to be hydrophilous, zoophilous pollination by macro invertebrates is also possible (van Tussenbroek et al, 2012). There is also growing evidence of a faunal contribution to seed dispersal (Sumoski and Orth, 2012).…”

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.
