Dear Editors, We appreciate the growing patients and survivors. Mazzola interest in sexual health for cancer and Mulhall＇s recent paper,a however, creates the impression that rewarding sex is not possible for prostate cancer patients on androgen deprivation therapy （ADT）. This impression, we believe, is not scientifically justified,

Alarm calls are emitted by Richardson＇s ground squirrels Urocitellus richardsonii in response to avian and terrestrial predators. Conspecifics detecting these calls respond with increased vigilance, promoting predator detection and evasion, but in doing so, lose time from foraging. That loss can be minimized if alarm call recipients discriminate among signalers, and weight their response accordingly. For juvenile ground squirrels, we predicted that the trade-off between foraging and vigilance could be optimized via selective response to alarm calls emitted by their own dam, and/or neighboring colony members over calls broad- cast by less familiar conspecifics. Alarm calls of adult female Richardson＇s ground squirrels were elicited in the field using a predator model and recorded on digital audio tape. Free-living focal juveniles were subjected to playbacks of a call of their mother, and on a separate occasion a call from either another adult female from their own colony, or an adult female from another colony. Neither immediate postural responses and escape behavior, nor the duration of vigilance manifested by juveniles differed with exposure to alarm calls of the three adult female signaler types. Thus, juveniles did not respond preferentially to alarm calls emitted by their mothers or colony members, likely reflecting the high cost of ignoring alarm signals where receivers have had limited opportunity to establish past signaler reliability [Current Zoology 58 （5）： 773-780, 2012].

土壤质量的概念随着对土嚷认识的提高和着眼点的改变又赋予了它新的内涵。不同效用的土壤生产力和适宜性一直是土壤质量的主要内容,而诸如寻求解决土壤退化和改善土壤质量等内容则成为这一概念新的关注点。各种效用的土壤适宜性是最早的、最常用的土壤质量的概念之一。土壤质量通常与作物生产量相联系,但也与其质量紧密相关,这是因为决定着人类健康的土壤的“健康”是通过作物的质量来反映的。此外,由于土壤是许许多多生物群体唯一的生存环境,所以采用各种生物参数来确定土壤质量的内涵。更进一步的是根据各种土壤生态系统的功能如养分循环利用、降雨分配及缓冲作用来定义这一概念。除此之外,还有土壤的内在价值和独特性所定义的主观土壤质量概念。

Changes in Inositol Phosphates in Low Phytic Acid Field Pea (<i>Pisum sativum</i>L.) Lines during Germination and in Response to Fertilization

Inositol phosphates are the main form of phosphorous (P) storage in legume seeds. Mutants low in inositol hexaphosphate (IP6), also known as phytic acid (PA), have been developed to increase iron (Fe) bioavailability and reduce P waste to the environment. The objectives of this study were to determine 1) inositol-P form changes during germination, and 2) the effect of P fertilizer application on seed PA, total P, and Fe concentration of three field pea (Pisum sativum L.) cultivars and two low-PA lines grown under greenhouse conditions. Low-PA field pea lines clearly had lower PA (1.3 - 1.4 mg·g-1) than cultivars (3.1 - 3.7 mg·g-1). Phytic acid concentration in both cultivars and low-PA lines decreased during germination, but tended to increase seven days after germination. Levels of inositol-3-phosphate-phosphate (IP3-P;0.6 mg·g-1) and inorganic P (1.8 - 2.0 mg·g-1) were higher in low-PA lines than in the field pea cultivars. Reduction of PA in low-PA line seeds may reduce seed Fe and total P concentrations, as levels in the low-PA lines (37 - 42 mg·kg-1 Fe;4003 - 4473 mg·kg-1 total P) were typically less than in field pea cultivars (37 - 55 mg·kg-1 Fe;3208 - 4985 mg·kg-1 total P) at different P fertilizer rates. Overall, IP3 is the major form of P present in low-PA field pea lines during germination;however IP6 is the major form of P present in field pea cultivars. Therefore, low-PA field pea lines could be a potential solution to increase Fe bioavailability, feed P utilization, and reduce P waste to the environment.

Ornamental plants are distinguished by the shape and color of their leaves/flowers and their use in landscaping and gardening. In urban areas, their presence is relevant for the maintenance of bees. Aiming to list the ornamental bee plants species occurring in Santa Catarina State (SC), southern Brazil, a survey of forage resources for bees, recorded in the State, was performed. We refer all published works developed in SC (resulting in the period 1983-2014) which include data from reports of scientific research, monographs, dissertations, Masters Dissertations, Doctoral Thesis, annals of scientific events, scientific articles and books. From the 28 ensuant works, we listed, as ornamental bee plants occurring in SC, 201 species, of 156 genera and 66 botanical families. Of these species, 92 are native (N), 26 endemic to Brazil and 109 exotic (E). Families with more ornamental bee species are: Fabaceae (22 species), Asteraceae (20), Solanaceae (11), Rosaceae (10) and Lamiaceae (8). The most cited species are: Lantana camara L. (N) (Verbenaceae) (9 quotes), Aloysia virgata (N) (Ruiz & Pav.) Juss. (Verbenaceae) (8), Hedychium coronarium J. Koenig (naturalized) (Zingiberaceae) (6) and Brachyscome multifida (E) (Asteraceae) (5), regarding habitus, herbs (48.5%) predominate, followed by bushes (21.5%), trees (16.5%) and vines (10.5%). Preferred colours of flowers by bees are, in decreasing order: white, yellow, red/pink, and others. The genus Ipomoea, Calliandra, Passiflora, Prunus and Senecio have more ornamental bee plant species. A large botanical diversity arises, demonstrating the possibilities for urban bee foraging and ornamental featuring, in a perspective of sustainability.
