Horseshoe crabs have persisted for more than 200 million years, and fossil forms date to 450 years ago. The American horseshoe crab (Limulus polyphemus), one of four extant species, is found along the Atlantic coastline North America ranging from Alabama Maine, USA with another distinct population on coasts Campeche, Yucatán Quintana Roo in Peninsula, México. Although tolerates broad environmental conditions, exploitation habitat loss threaten species. We assessed conservation status by...
Horseshoe crabs are marine arthropods with a fossil record extending back approximately 450 million years. They exhibit remarkable morphological stability over their long evolutionary history, retaining number of ancestral arthropod traits, and often cited as examples "living fossils." As arthropods, they belong to the Ecdysozoa, an ancient super-phylum whose sequenced genomes (including insects nematodes) have thus far shown more divergence from pattern eumetazoan genome organization than...
Abstract Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 International Union for Conservation of Nature (IUCN) called development a “Green List Species” (now IUCN Green Status Species). A draft framework assessing species’ progress toward recovery, published 2018, proposed 2 separate but interlinked components: standardized method (i.e., measurement against benchmarks viability, functionality, preimpact distribution) determine current status (herein...
Like a number of other species, horseshoe crabs lay their eggs on beaches in the intertidal zone. The elevation beach which they nest differs among populations. We examined two factors that potentially affect egg survival at different elevations: erosion and rate development. found no evidence buried elevations incur risks by wave action. However, optimal for development differed between our study sites, Florida Delaware, difference was related to morphology. Rate increased with oxygen...
Abstract Horseshoe crabs have an explosive breeding system not unlike that of some frogs and toads. They synchronize nesting to only a few hours each day at the time spring new full-moon high tides. Males search for females as they come beaches, grasp them with specially modified claws cling them, sometimes weeks. Females lay several clutches eggs in sand male fertilizes externally, extant arthropod such reproductive system. Unattached males cluster around couple, pushing on occasionally...
Abstract One suggested evolutionary origin of insect sociality is joint nesting by females the same generation. Long before selection favoured itself, it might have some other incidental preadaptation such as habit 'entering' abandoned burrows, found in usually solitary wasp Splaex ichneumoneus. We comprehensive economic records individually marked wasps. There little evidence consistent individual variation success. Wasps often abandon nests they dug, and individuals adopt or 'enter' these...
We present an analysis of bird distribution in small islands the northern Lesser Antilles colonized principally from Guadeloupe. In spite great differences among soils, rainfall, and vegetation, their avifaunas are strikingly uniform. found that species inhabiting coastal scrub on source island performed better as colonists than inhabitants interior rainforest, suggesting humid forests target would hold drastically impoverished communities. This proved not to be case. Diversities...
Abstract Fourteen microsatellite DNA loci were surveyed in 892 horseshoe crabs Limulus polyphemus collected from 21 sites ranging Franklin, Maine, to the Yucatán Peninsula, Mexico. This rangewide survey revealed a high degree of genetic diversity (up 50 alleles per locus) and heterozygosity 97.2%). There appears be substantial gene flow between each population its nearest neighbors. The correlation distance geographic supports isolation by as mechanism underlying structure L. along Atlantic...
