New dimensions of tropical diversity: an inordinate fondness for insect molecules, taxa, and trophic interactions

Most known insect species are involved in chemically mediated plant–insect multi-trophic interactions, and recent syntheses point to a substantial gap in our understanding of trophic interaction diversity, especially in the tropics. One approach to filling this gap is to examine relationships between genomic, metabolomic, taxonomic, and trophic interaction diversity via quantifying and comparin...

An asymmetry in niche conservatism contributes to the latitudinal species diversity gradient in New World vertebrates.

The Tropical Niche Conservatism hypothesis is a leading explanation for why biodiversity increases towards the equator. The model suggests that most lineages have tropical origins, with few dispersing into temperate regions. However, biotas are comprised of lineages with differing geographical origins, thus it is unclear whether lineages that originated on different continents will exhibit simi...

Historical factors that have shaped the evolution of tropical reef fishes: a review of phylogenies, biogeography, and remaining questions

Biodiversity patterns across the marine tropics have intrigued evolutionary biologists and ecologists alike. Tropical coral reefs host 1/3 of all marine species of fish on 0.1% of the ocean's surface. Yet our understanding of how mechanistic processes have underpinned the generation of this diversity is limited. However, it has become clear that the biogeographic history of the marine tropics h...

Identification species of Demospongiae sponge at Assaluyeh Persian Gulf

The marine environment is a rich source of biodiversity and chemical compounds, and based on biodiversity knowledge, it is believed that the highest biodiversity is related to living organisms in tropical and semi-equatorial regions. The goal of this study was the biodiversity of Demospongiae sponge in Assaluyeh area in May 2018. Sampling carried oyu by using Coadrat in three sites with three r...

Are there many different routes to becoming a global biodiversity hotspot?

A major question in evolution and ecology is why biodiversity is so unevenly distributed across the planet. The most obvious and salient diversity pattern is the order-of-magnitude greater species richness in the tropics compared with the temperate zones. Superimposed on this latitudinal diversity gradient is a much more complex and intricate pattern of regional andmore local biodiversity hotsp...
