Although the insect circulatory system is involved in a multitude of vital physiological processes, it has gone grossly understudied. This review highlights this critical by detailing structure and function ...Read More

Why some species of animals would lose such obviously adaptive characters as eyes and pigmentation to live only in the seemingly inhospitable environ­ ment caves has long intrigued both laymen biologists. Evidence that early man recognized cave invertebrates dates back an engraving a cricket, Troglophilus sp., on bison bone, discovered French Pyrenees (161), believed be 18,000 years old (86). However, serious studies faunas began about 150 ago (5, 6). Vandel's monograph (161) provides most...

Abstract: The introduction of alien, or nonindigenous, animals and plants has been identified by scientists policy makers as a major threat to biodiversity in marine ecosystems. Although government agencies have struggled control alien species on land freshwater for decades with mixed success, the is its infancy. Prevention establishment must be first priority, but many populations are already well established worldwide. National international policies leave loopholes additional invasions...

Ever-increasing human pressures on cave biodiversity have amplified the need for systematic, repeatable, and intensive surveys of cave-dwelling arthropods to formulate evidence-based management decisions. We examined 110 papers (from 1967 2018) to: (i) understand how invertebrates been sampled; (ii) provide a summary techniques most commonly applied appropriateness these techniques, and; (iii) make recommendations sampling design improvement. Of studies reviewed, over half (56) were...

Abstract The 15th UN Convention on Biological Diversity (CBD) (COP15) will be held in Kunming, China October 2021. Historically, CBDs and other multilateral treaties have either alluded to or entirely overlooked the subterranean biome. A effort robustly examine, monitor, incorporate biome into future conservation targets enable CBD further improve ecological effectiveness of protected areas by including groundwater resources, ecosystem services, profoundly endemic subsurface biodiversity. To...

Recent discoveries of obligate cave species in the tropics and medium-sized subterranean voids provide opportunities to test hypotheses developed during pioneering work temperate limestone caves. Most share similar morphological, physiological, behavioral features, which indicates presence strong selection forces their highly stressful environment. Major stresses include perpetual darkness humidity, lack important environmental cues, complex mazelike living space, or even lethal gas...

The discovery of terrestrial troglobites living in caves on young oceanic islands with close epigean relatives nearby surface habitats offers unique opportunities to develop and test hypotheses concerning their evolution. Studies comparing the physiological ecology suggest that are highly specialized exploit resources within system interconnected medium-sized voids (mesocaverns) only colonize cave passages (macrocaverns) a stable, water vapor-saturated atmosphere. Few other animals can live...

Cave-adapted arthropods have evolved in lava tubes Hawaii. This is the first report of cavernicoles from Hawaiian islands. The specialization cavernicolous insects and recent origin suggest that subterranean connections between regularly occur provide dispersal routes. discovery were colonized by representatives adaptively radiating native fauna offers significant potential for evolutionary studies.

The Hawaiian Islands provide the venue of one nature’s grand experiments in evolution. Here, we present morphological, behavioral, genetic, and geologic data from a young subterranean insect lineage lava tube caves on Hawai‘i Island. Oliarus polyphemus species complex has potential to become model for studying rapid speciation by stochastic events. All this live extremely similar environments but show strong differentiation behavioral morphometric characters, which are random with respect...
