Cuticular nitrogen economy during development in the cockroach Cryptocercus punctulatus and the termite Neotermes jouteli.

The role of nitrogen during insect development and reproduction is key in the success of a species, and is of primary importance in wood feeding taxa. Based on comparison of xylophagous, one-piece termites to the termite sister group, subsocial wood-feeding cockroaches in the genus Cryptocercus, it has been proposed that the evolution of termite eusociality involved a fundamental shift in nitrogen allocation strategies. Cryptocercus exhibits a nitrogen storage economy, with individuals gradually increasing in size and cuticular density over a years-long developmental period.

Floridanema gen. nov. (Aerosakkonemataceae, Aerosakkonematales ord. nov., Cyanobacteria) from benthic tropical and subtropical fresh waters, with the description of four new species.

Cyanobacteria exhibit a vast diversity from polar to tropical environments. Though much work has been done on elucidating their biodiversity, knowledge on the occurrence, diversity and toxicity of benthic cyanobacteria is limited when compared to the planktonic forms. Integrating molecular techniques with ecological and morphological analyses has become essential in untangling cyanobacterial diversity, particularly for benthic taxa such as the cryptic "Lyngbya.

Evidence-base for urban green-blue infrastructure to support insect diversity.

Unlabelled: Green-blue urban infrastructures potentially offer win-win benefits for people and nature in urban areas. Given increasing evidence of widespread declines of insects, as well as their ecological importance, there is a need to better understand the potential role of green-blue urban infrastructure for insect conservation. In this review, we evaluated 201 studies about the ability of green-blue infrastructure to support insect diversity.

A new species of planthopper in the genus Platocerella (Hemiptera: Auchenorrhyncha: Derbidae) from palms in Costa Rica, a key to the genus and an updated molecular phylogeny of available New World Otiocerinae.

The genus Platocerella is a monotypic otiocerine genus (Derbidae: Otiocerinae: Otiocerini) reported from Guyana. A new species of Platocerella associated with palms is herein described from Costa Rica. Molecular data for the barcoding region cytochrome c oxidase subunit I (COI), 18S rRNA gene, and D9-D10 expansion region of the 28S rRNA gene is provided to produce a preliminary phylogenetic tree including the new species and related taxa to place the new species relative to other otiocerine planthoppers.

Expanded range of Nasutitermes callimorphus Mathews, 1977 (Isoptera: Termitidae: Nasutitermitinae), comparison with N. corniger (Motschulsky, 1855) and N. ephratae (Holmgren, 1910), and synonymy of N. dasyopsis Thorne, 1989 into N. nigriceps (Haldeman, 1854).

The imago of N. callimorphus is described for the first time. Nasutitermes callimorphus occurs from Mexico to Paraguay.

Dentispicotermes trapezia (Isoptera: Termitidae: Amitermitinae), a new termite species from the Pantanal-Chaco Region of South America.

Dentispicotermes trapezia sp. nov. is described from the soldier and worker castes of specimens collected in Pantanal-Chaco Region of Bolivia and Paraguay.

A new species of planthopper in the genus Myconus (Hemiptera: Auchenorrhyncha: Fulgoroidea: Achilidae) from the Osa Peninsula in Costa Rica.

Recent surveys of palm-associated planthoppers in Costa Rica have revealed many new species, primarily in the families Derbidae and Cixiidae, but also Myconus jacquelinae Bahder & Bartlett, in the Achilidae. Here a new species of Myconus from the the Osa peninsula is described as Myconus florae sp. n.

causes rachis blight on coconut palms ( L.) in Florida.

, a genus in the family Botryosphaeriaceae, has a broad host range and causes dieback, root rot, fruit rot, leaf rot, and blights in many plant species across sub-tropical and tropical geographical areas (Alves et al., 2008). In palms, this fungal pathogen is known to cause fruit and heart rot, wood decay and leaf blight around the globe (Atallah et al.

Effectiveness of ozone nanobubble treatments on high biomass cyanobacterial blooms: A mesocosm experiment and field trial.

Cyanobacterial harmful algae blooms (cyanoHABs) are a global threat to water resources, and lake managers need effective strategies to suppress or control them. Algaecides may have negative environmental impacts, and their use is becoming restricted. Nanobubble ozone technology (NBOT) is an emerging water treatment option with potentially fewer negative impacts.

Engineered Mg-modified biochar-based sorbent for arsenic separation and pre-concentration.

The utilization of biochar as a relatively efficient sorbent or stationary phase for the separation and preconcentration of a wide range of analytes represents an innovative approach in current sample pretreatment methods. Appropriate pre- and post-pyrolysis modification of the input precursor and pyrolysis product, respectively, allows targeted design of the physicochemical properties and sorption characteristics of the resulting sorbent. The present work deals with the preparation of pyrolysis materials based on unmodified cattail leaf biomass (BC) and its Mg-modified analogue (MgBC) by a slow pyrolysis process at 500 °C and a residence time of 1 h in a pyrolysis reactor.

Genome sequences of toxigenic cyanobacteria from a bloom in Lake Mattamuskeet, North Carolina (United States).

Lake Mattamuskeet, the largest lake in North Carolina, USA, has undergone decades-long eutrophication causing reduced water quality and promoting cyanobacterial blooms that may produce toxins. It is therefore necessary to evaluate the cyanobacterial diversity of the lake and their toxigenic potential. We present draft genomes of Microcystis, Pelatocladus, Raphidiopsis, and Umezakia strains isolated from Lake Mattamuskeet.

Functional effects of subsidies and stressors on benthic microbial communities along freshwater to marine gradients.

Leaf litter in coastal wetlands lays the foundation for carbon storage, and the creation of coastal wetland soils. As climate change alters the biogeochemical conditions and macrophyte composition of coastal wetlands, a better understanding of the interactions between microbial communities, changing chemistry, and leaf litter is required to understand the dynamics of coastal litter breakdown in changing wetlands. Coastal wetlands are dynamic systems with shifting biogeochemical conditions, with both tidal and seasonal redox fluctuations, and marine subsidies to inland habitats.

Fitness consequences of anthropogenic subsidies for a partially migratory wading bird.

Human activities are forcing wildlife to confront selective pressures different from those under which they evolved. In seasonal environments, migration evolved as an adaptation to fluctuating resource availability. Anthropogenic subsidies modify resource dynamics by providing a steady food source that is not subject to seasonality.

Employing targeted outreach to improve community involvement in detecting invasive Nile monitors (Varanus niloticus) in Florida.

We successfully employed targeted outreach to communities in Palm Beach County, Florida, to enhance detection of invasive reptiles. We defined targeted outreach as delivering a specific message to a specific audience, at a specific location, to obtain a specific result. These efforts improved our ability to solicit community involvement focused on target species of interest in locations at risk of potential establishment of incipient populations.

Assessing abundance-suitability models to prioritize conservation areas for the dwarf caimans in South America.

Species-environment relationships have been extensively explored through species distribution models (SDM) and species abundance models (SAM), which have become key components to understand the spatial ecology and population dynamics directed at biodiversity conservation. Nonetheless, within the internal structure of species' ranges, habitat suitability and species abundance do not always show similar patterns, and using information derived from either SDM or SAM could be incomplete and mislead conservation efforts. We gauged support for the abundance-suitability relationship and used the combined information to prioritize the conservation of South American dwarf caimans ( and ).

Unraveling spatial heterogeneity of soil legacy phosphorus in subtropical grasslands.

Humans have profoundly altered phosphorus (P) cycling across scales. Agriculturally driven changes (e.g.

Soil legacy phosphorus and loss risk in subtropical grasslands.

The accumulation of soil legacy phosphorus (P) due to past fertilization practices poses a persistent challenge for agroecosystem management and water quality conservation. This study investigates the spatial distribution and risk assessment of soil legacy P in subtropical grasslands managed for cow-calf operations in Florida, with two pasture types along the intensity gradient: improved vs semi-native pastures. Soil samples from 1438 locations revealed substantial spatial variation in soil legacy P, with total P concentrations ranging from 11.
