TL;DR: Training counselors on issues of sexuality and safer sex will benefit victims of IPV, and a large percentage of participants reported being forced by their partners to have sex.
Abstract: To date, there has been little research examining HIV/STD risk among lesbian, gay, bisexual, and transgender (LGBT) individuals who are in abusive relationships. This article uses data collected from a community-based organization that provides counseling for LGBT victims of intimate partner violence (IPV). A total of 58 clients completed the survey, which inquired as to sexual violence and difficulties negotiating safer sex with their abusive partners. A large percentage of participants reported being forced by their partners to have sex (41%). Many stated that they felt unsafe to ask their abusive partners to use safer sex protection or that they feared their partners' response to safer sex (28%). In addition, many participants experienced sexual (19%), physical (21%), and/or verbal abuse (32%) as a direct consequence of asking their partner to use safer sex protection. Training counselors on issues of sexuality and safer sex will benefit victims of IPV.

TL;DR: It is concluded that species distribution under the sort of elevated CO2 conditions occurring with leakages from geological storages and future ocean acidification scenarios, may partly be determined by quite subtle physiological differentiation.

TL;DR: Experimental results are presented that show that potential accuracy limitations introduced by the physical layer of the IEEE 802.11b wireless local area network do not preclude clock-synchronization accuracy of several hundred nanoseconds.
Abstract: IEEE 1588 is a new standard to synchronize independent clocks running on separate nodes of a distributed measurement and control system. It is intended for high-accuracy implementations on compact systems such as a single subnet. This paper examines potential accuracy limitations introduced by the physical layer of the IEEE 802.11b wireless local area network. Experimental results are presented that show that these limitations do not preclude clock-synchronization accuracy of several hundred nanoseconds.

TL;DR: The results of this study suggest P. regilla should act as a Bd reservoir and provide evidence of a tolerance mechanism in a reservoir species, as well as examining tissues with histology to determine patterns of infection.
Abstract: Chytridiomycosis, a disease caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), is driving amphibian declines and extinctions in protected areas globally. The introduction of invasive reservoir species has been implicated in the spread of Bd but does not explain the appearance of the pathogen in remote protected areas. In the high elevation (>1500 m) Sierra Nevada of California, the native Pacific chorus frog, Pseudacris regilla, appears unaffected by chytridiomycosis while sympatric species experience catastrophic declines. We investigated whether P. regilla is a reservoir of Bd by comparing habitat occupancy before and after a major Bd outbreak and measuring infection in P. regilla in the field, monitoring susceptibility of P. regilla to Bd in the laboratory, examining tissues with histology to determine patterns of infection, and using an innovative soak technique to determine individual output of Bd zoospores in water. Pseudacris regilla persists at 100% of sites where a sympatric species has been extirpated from 72% in synchrony with a wave of Bd. In the laboratory, P. regilla carried loads of Bd as much as an order of magnitude higher than loads found lethal to sympatric species. Histology shows heavy Bd infection in patchy areas next to normal skin, a possible mechanism for tolerance. The soak technique was 77.8% effective at detecting Bd in water and showed an average output of 68 zoospores per minute per individual. The results of this study suggest P. regilla should act as a Bd reservoir and provide evidence of a tolerance mechanism in a reservoir species.

TL;DR: On the basis of power-law species–area relationships, link–area and non-power-law link–species models that accurately predict how trophic links scale with area and species richness of microcosms, lakes and streams from community to metacommunity levels are developed.
Abstract: Two largely independent bodies of scaling theory address the quantitative relationships between habitat area, species diversity and trophic interactions. Spatial theory within macroecology addresses how species richness scales with area in landscapes, while typically ignoring interspecific interactions. Complexity theory within community ecology addresses how trophic links scale with species richness in food webs, while typically ignoring spatial considerations. Recent studies suggest unifying these theories by demonstrating how spatial patterns influence food-web structure and vice versa. Here, we follow this suggestion by developing and empirically testing a more unified scaling theory. On the basis of power-law species-area relationships, we develop link-area and non-power-law link-species models that accurately predict how trophic links scale with area and species richness of microcosms, lakes and streams from community to metacommunity levels. In contrast to previous models that assume that species richness alone determines the number of trophic links, these models include the species' spatial distribution, and hence extend the domain of complexity theory to metacommunity scales. This generality and predictive success shows how complexity theory and spatial theory can be unified into a much more general theory addressing new domains of ecology.
