“…Furthermore, investigating how disturbances affect soil nesting native bees would advance our understanding of bee biology in a unique riparian community. Further, ecological restoration involving native plants could assist in management of invasive reed grass, coupled with other benefits from intensified riparian management involving giant reed (Patiño et al 2018). Ecological restoration towards native vegetation could support initiative for management of the corridor by reestablishing native vegetation to replace dense stands of giant reed.…”

5The Lower Rio Grande River (LRGR) in Texas is the physical boundary between the United 6 States and Mexico and is considered one of the world's most at-risk rivers due to intensified 7 management of the riparian corridor and human use. Exotic plant invasions have significantly 8 altered the native floral communities because of invasive giant reed, with potential impacts to the 9 native wildlife using resources in the riparian corridor. This study was conducted along a 3.22 10 km stretch of the LRGR in southwestern Webb County, TX to assess bee (Anthophila) 11 communities and their flowering-plant resources among proximal and distal terrestrial upland 12 and river-adjacent sub-corridors. Patterns related to the bee community across the two habitats 13 consisted of low variation and dominance by common taxa, suggesting the riparian corridor 14 could be used as a resource for bee foraging and soil-nesting. Although a lack of community 15 structure similarities among habitats were found, indicator species analysis produced two bee 16 genera that were more common and abundant in the upland habitat. Total number of individual 17 bees and genera collected across 26 dates and 2 years show a bimodal trend, with peaks in 18

“…Modified ASM at salinity of 5 (ASM‐5) is a relatively simple, brackish medium that has been used previously to study Prymnesium parvum growth (Rashel and Patiño 2017, 2019, Dabney and Patiño 2018, Patiño et al. 2018). Instant Ocean ® Sea Salts medium at a salinity of 30 (IO‐30) contains a more complete suite of salts comparable to that of authentic seawater (Atkinson and Bingman 1998).…”

Prymnesium parvum is a euryhaline, toxin‐producing microalga. Although its abundance in inland waters and growth potential in the laboratory is reduced at high salinity (>20), the ability of inland strains to adjust their growth after long‐term residence in high salinity is uncertain. An inland strain of P. parvum maintained at salinity of 5 in modified artificial seawater medium (ASM‐5) was subjected to the following treatments over five sequential batch culture rounds: ASM‐5 (control); modified ASM at salinity of 30, raised with NaCl; modified ASM at salinity incrementally increased to 30 with NaCl; and Instant Ocean® at salinity of 30 (IO‐30). Exponential growth rate (r) was reduced when salinity was increased from 5 to 30 in ASM but returned to control values during the second round. When salinity was incrementally increased, a reduction in r still occurred when salinity reached 25‐30. Maximum density was reduced at salinity of 30 in ASM upon abrupt transfer or incremental increase, and compensation did not occur. Growth performance in IO‐30 was comparable to control values. In conclusion, (i) long‐term compensation for acute inhibitory effects of high salinity occurred for r but not maximum density, (ii) incremental increases in salinity did not prevent growth inhibition, suggesting the existence of a salinity threshold of 25–30 for onset of salinity stress, and (iii) the presence of a seawater‐like salt mixture prevented growth inhibition by high salinity. These findings provide new insights on P. parvum's long‐term ability to adjust its growth in environments of different salinity and ionic composition.

“…Acidic and neutral/ alkaline fractions have been reported to inhibit Prymnesium parvum, ichthyotoxic golden alga. 1 In addition, traditional medicine has used A. donax L. as an emollient and a diuretic agent. 2,3 Furthermore, basic biomedical research has used the rhizome from which purified n-acetyl-D-glucosamine was obtained.…”

Plant materials and extraction Whole plants of A. donax L. during the flowering stage were collected in Thailand. The voucher specimen was prepared by Forest Herbarium (BKF) Department of National Parks, Wildlife and Plant Conservation, Ministry of Natural Resources and Environment to use as plant reference (Reference number: BKF NO. 19581). The voucher specimen compared with that in BKF database was identified as A. donax L. by Mr. Sukid Rueangruea, Forestier Professional Academician of BKF. A. donax L.
