  • Black River Pilot Project
    Final Project report for the ‘Mitigating the Threat of Invasive Alien Species (IAS) in the Insular Caribbean project: Black River IAS Pilot Project’ Prepared and submitted by Dr Kurt McLaren (Principal investigator [PI]/Project manager) 1 1. Introduction The Black River morass is the largest freshwater wetland ecosystem in Jamaica and the second largest in the Caribbean. It is a biologically diverse and extremely complex natural wetland ecosystem that supports a large number of plants, animals and natural communities. The Morass support high levels of endemic species which are severely threatened by anthropogenic disturbance owing to their relatively small size and accessibility to human encroachment. In recognition of its value as a reservoir of endemic biodiversity, and its contribution to the livelihoods of local communities, the Black River morass will be designated as a protected area in 2015. It was also designated as a Ramsar site in 1997, signifying that it is a wetland ecosystem of international importance. The Ramsar designation should provide both the impetus for national action and the framework for international cooperation geared towards the conservation and sustainable use of this important wetland. To date however, the threats to the Black River morass remain unchecked (selective removal of trees, burning, the cultivation of marijuana and habitat encroachment), resulting in the continued loss or degradation of various habitat types. Conservation of the swamp forest is challenged by on-going human impacts (e.g., tree cutting, fires) and is compounded by the establishment of two exotic plant species that are at different stages of invasion. Although it may be possible to eradicate the more recently introduced invasive, Melaleuca quinquenervia, the other invasive, Alpinia allughas, is now firmly established.

Their occasional presence in embryos, ®rst noticed over 100 years ago, has gone lar- gely unexamined. d Methods Embryos from 148 taxa of palms, the largest survey of palm embryos to date, were examined using light microscopy of squashed preparations under non-polarized and crossed polarized light. d Key Results Raphides were found in embryos of species from the three subfamilies Coryphoideae, Ceroxyloideae and Arecoideae. Raphides were not observed in the embryos of species of Calamoideae or Phytelephantoideae. The remaining subfamily, the monospeci®c Nypoideae, was not available for study. d Conclusions Within the Coryphoideae and Ceroxyloideae, embryos with raphides were rare, but within the Arecoideae, they were a common feature of the tribes Areceae and Caryoteae. ã 2004 Annals of Botany Company Key words: Anatomy, Arecaceae, calcium oxalate, embryology, embryos, Palmae, raphides.

Accepted: April 19, 2019 Data deposition: This project has been deposited at the NCBI Sequence Read Archive under the accession BioProject (PRJNA313089). Abstract Mechanisms of genome evolution are fundamental to our understanding of adaptation and the generation and maintenance of biodiversity, yet genome dynamics are still poorly characterized in many clades. Strong correlations between variation in genomic attributes and species diversity across the plant tree of life suggest that polyploidy or other mechanisms of genome size change confer selective advantages due to the introduction of genomic novelty.

Most monocot relationships are robust (an average of ca. 91% bootstrap support per branch examined), including those poorly supported or unresolved in other studies. Our data strongly support a sister-group relationship between Asparagales and the commelinid monocots, the inclusion of the orchids in Asparagales, and the status of Petro- saviaceae as the sister group of all monocots except Acorus and Alismatales.

Accepted: April 19, 2019 Data deposition: This project has been deposited at the NCBI Sequence Read Archive under the accession BioProject (PRJNA313089). Abstract Mechanisms of genome evolution are fundamental to our understanding of adaptation and the generation and maintenance of biodiversity, yet genome dynamics are still poorly characterized in many clades. Strong correlations between variation in genomic attributes and species diversity across the plant tree of life suggest that polyploidy or other mechanisms of genome size change confer selective advantages due to the introduction of genomic novelty. Palms (order Arecales, family Arecaceae) are diverse, widespread, and dominant in tropical ecosystems, yet little is known about genome evolution in this ecologically and economically important clade. Here, we take a phylogenetic comparative approach to investigate palm genome dynamics using genomic and transcriptomic data in combination with a recent, densely sampled, phylogenetic tree. We find conclusive evidence of a paleopolyploid event shared by the ancestor of palms but not with the sister clade, Dasypogonales. We find evidence of incremental chromosome number change in the palms as opposed to one of recurrent polyploidy.
