Environmental Factors Influencing Primary Productivity Of The Forest-Forming Kelp Laminaria Hyperborea In The Northeast Atlantic, Dan A. Smale, Albert Pessarrodona, Nathan King, Michael T. Burrows, Anna Yunnie, Thomas Vance, Pippa Moore

ECU Publications Post 2013

© 2020, The Author(s). Rates and drivers of primary productivity are well understood for many terrestrial ecosystems, but remain poorly resolved for many marine ecosystems, particularly those within in coastal benthic environments. We quantified net primary productivity (NPP) using two methods as well as carbon standing stock within kelp forests (Laminaria hyperborea) at multiple subtidal habitats in the United Kingdom (UK). Study sites spanned 9° in latitude and encompassed a gradient in average temperature of ~ 2.5 °C. In addition to temperature, we measured other factors (e.g. light intensity, water motion, nutrients, sea urchin density) that may influence productivity ...


Effect Of Biocrust Development On Establishment Of Native Plants In A Salt Desert System, Merran Owen 2020 Utah State University

Effect Of Biocrust Development On Establishment Of Native Plants In A Salt Desert System, Merran Owen

All Graduate Theses and Dissertations

Salt desert shrublands are semiarid, shrub-dominated ecosystems that inhabit salt- affected soils. In Great Basin salt deserts, exotic annual plants are invading and displacing native plants. Low plant productivity and slow population growth of native plants in these ecosystems makes them vulnerable to invasion and limits their ability to compete with invasive plants and return to a natural state. Active revegetation efforts, such as planting and direct seeding of native plants, are often unsuccessful for the same reasons. Biological soil crusts (communities of cyanobacteria, lichen, moss, microfungi and other microorganisms that live on the surface layer of the soil) are ...


Lack Of Consensus On An Aging Biology Paradigm? A Global Survey Reveals An Agreement To Disagree, And The Need For An Interdisciplinary Framework, Alan A. Cohen, Anne M. Bronikowski, Luigi Ferrucci, et al. 2020 University of Sherbrooke

Lack Of Consensus On An Aging Biology Paradigm? A Global Survey Reveals An Agreement To Disagree, And The Need For An Interdisciplinary Framework, Alan A. Cohen, Anne M. Bronikowski, Luigi Ferrucci, Et Al.

Ecology, Evolution and Organismal Biology Publications

At a recent symposium on aging biology, a debate was held as to whether or not we know what biological aging is. Most of the participants were struck not only by the lack of consensus on this core question, but also on many basic tenets of the field. Accordingly, we undertook a systematic survey of our 71 participants on key questions that were raised during the debate and symposium, eliciting 37 responses. The results confirmed the impression from the symposium: there is marked disagreement on the most fundamental questions in the field, and little consensus on anything other than the ...

Systematic Status Of The Chilean Genus Carlota Arias-Bohart, 2014 (Coleoptera: Elateridae: Agrypninae: Agrypnini), Elizabeth T. Arias-Bohart 2020 Essig Museum of Entomology, University of California

Systematic Status Of The Chilean Genus Carlota Arias-Bohart, 2014 (Coleoptera: Elateridae: Agrypninae: Agrypnini), Elizabeth T. Arias-Bohart

Insecta Mundi

The click beetle genus Carlota Arias-Bohart (Coleoptera: Elateridae: Agrypninae: Agrypnini) was considered as a junior synonym of Candanius Hayek recently. However, there are deep morphological differences between these genera which justify the validity of Carlota. The morphology of this genus was re-examined in detail and based on the short and shallow antennal grooves, strongly serrate antennae from antennomeres 3 through 10, subquadrate pronotum with four distinct subcircular depressions, and straight prosternal process not bent dorsally, I resurrect the genus Carlota from synonymy.

On Speciation And Hybridization Among Closely Related Species: Establishing An Experimental Breeding Lineage Between Two Species Of Automeris Hübner Moths (Lepidoptera: Saturniidae) And Implications For Taxonomy, Andrei Sourakov, Cassandra Doll, Alyssa M. Quinn, Lei Xiao, Eric Anderson

Insecta Mundi

Many species of plants and a few species of animals are believed to have resulted from hybridization of parental species, and the ability of species to occasionally hybridize in captivity and in nature is even more widespread. In the present study, we describe a hybridization experiment conducted in the laboratory between the sexually dimorphic Automeris io (Fabricius), a widespread, variable species ranging from Canada to Costa Rica, and its congener A. louisiana (Ferguson and Brou), a more local, sexually monomorphic species (Lepidoptera: Saturniidae). The A. louisiana populations occur in a highly specialized habitat—the coastal marshland along the Gulf of ...

A New Species Of The Spittlebug Genus Clastoptera Germar (Hemiptera: Cercopoidea: Clastopteridae) On Florida Oaks, Vinton Thompson, Susan E. Halbert, Mark Rothschild

Insecta Mundi

Over the past decade, a previously unrecorded spittlebug of the genus Clastoptera Germar (Hemip­tera: Cercopoidea: Clastopteridae) has been observed in abundance on oaks (Quercus L. spp., Fagaceae) in several Florida counties. We describe this spittlebug as a new species, Clastoptera querci Thompson, Halbert and Rothschild, new species, provide information on its life history, host plants and distribution, and place it in the context of other members of the genus. Clastoptera spp. can transmit Xylella fastidiosa Wells et al., a bacterial pathogen that causes bacterial leaf scorch associated with oak decline. Thus C. querci should be monitored as a possible ...

The Role Of Microhabitats In Structuring Cave Invertebrate Communities In Guatemala, Gabrielle S.M. Pacheco, Marconi Souza Silva, Enio Cano, Rodrigo L. Ferreira 2020 Universidade Federal de Lavras

The Role Of Microhabitats In Structuring Cave Invertebrate Communities In Guatemala, Gabrielle S.M. Pacheco, Marconi Souza Silva, Enio Cano, Rodrigo L. Ferreira

International Journal of Speleology

Several studies have tried to elucidate the main environmental features driving invertebrate community structure in cave environments. They found that many factors influence the community structure, but rarely focused on how substrate types and heterogeneity might shape these communities. Therefore, the objective of this study was to assess which substrate features and whether or not substrate heterogeneity determines the invertebrate community structure (species richness and composition) in a set of limestone caves in Guatemala. We hypothesized that the troglobitic fauna responds differently to habitat structure regarding species richness and composition than non-troglobitic fauna because they are more specialized to live ...


Ecological Factors Influencing Wild Pig Damage To Planted Pine And Hardwood Seedlings, Micah P. Fern, James B. Armstrong, Rebecca J. Barlow, John S. Kush 2020 Union University

Ecological Factors Influencing Wild Pig Damage To Planted Pine And Hardwood Seedlings, Micah P. Fern, James B. Armstrong, Rebecca J. Barlow, John S. Kush

Human–Wildlife Interactions

Expanding wild pig (Sus scrofa) populations across the southern United States has the potential to impact longleaf pine (Pinus palustris) restoration efforts. The depredation of planted pine seedlings is the most widespread and economically costly damage caused by wild pigs in forest plantations. A better understanding of the ecological factors affecting depredation rates will allow managers to implement best management practices to reduce seedling mortality from wild pigs at their most vulnerable stage of growth. From March 2016 to March 2017, we evaluated wild pig preferences for planted pine and hardwood species at a 34.4-ha cutover site and 4 ...
