Figure 15 in Maratus playa, a new peacock spider in the fimbriatus group from Australia (Araneae: Salticidae: Euophryini)
Figure 15 (continued on next page). Display positions by the male Maratus playa types in front of a female. 9, Note movement of the pedipalps to expose the dark, glabrous surface of each paturon.

Figure 22. Positions assumed by a mating pair of Maratus playa. Here rotation of the female opisthosoma during mating was far less than the ~180° rotation observed for many other Maratus species.
Figure 27 in Maratus playa, a new peacock spider in the fimbriatus group from Australia (Araneae: Salticidae: Euophryini)
Figure 27. Male (1-2) Maratus playa and two other spiders (3-4) that may be Maratus playa, observed near Lake Goongarrie in the interior of Western Australia (references 11-12 in Table 1). 3, This could be a penultimate male. 4, Adult female. Since selection of immature and female colouration is thought be driven by their need for concealment rather than display, colouration might be expected to vary between localities.

Figure 1 in Maratus playa, a new peacock spider in the fimbriatus group from Australia (Araneae: Salticidae: Euophryini)
Figure 1. Courtship display by a male Maratus playa, sp. nov. Display by this species is similar to that of other species in the fimbriatus group, but the distinctive pattern of setae on the dorsal opisthosoma (fan) of this species makes it easy to identify.
Playa-Montmany, et al.: The thermoregulatory role of relative bill and leg surface areas in a Mediterranean population of Great tit
<p>There is growing evidence on the role of legs and bill as 'thermal windows' in birds coping with heat stress. However, there is a lack of empirical work examining the relationship between the relative bill and/or leg surface areas and key thermoregulatory traits such as the limits of the thermoneutral zone (TNZ) or the cooling efficiency at high temperatures. Here, we explored this relationship in a Mediterranean population of Great tit (<i>Parus major</i>) facing increasing thermal stress in its environment. The lower and upper critical limits of the TNZ were found to be 17.7 ± 1.6°C and 34.5 ± 0.7°C, respectively, and the basal metabolic rate was 0.96 ± 0.12 ml O<sub>2</sub> min<sup>-1 </sup>on average. The evaporative water loss (EWL) inflection point was established at 31.85 ± 0.27°C<sup> </sup>and was not significantly different from the value of the upper critical limit. No significant relationship was observed between the relative bill or tarsi size and TNZ critical limits, breadth, mass-independent VO<sub>2</sub> or mass-independent EWL at any environmental temperature (from 10°C to 40°C). However, Great tit males (but not females) with larger tarsi areas (a proxy of leg surface area) showed higher cooling efficiencies at 40°C. We found no support for the hypothesis that the bill surface area plays a significant role as a thermal window in Great tits, but the leg surface areas may play a role in males' physiological responses to high temperatures. On the one hand, we argue that the studied population occupies habitats with available microclimates and fresh water for drinking during summer, so active heat dissipation by EWL might be favored instead of dry heat loss through the bill surface. Conversely, male dominance behaviors could imply a greater dependence on cutaneous evaporative water loss through the upper leg surfaces as a consequence of higher exposure to harsh environmental conditions than faced by females.</p>

Basura plástica y microplásticos: contaminantes emergentes presentes en sedimentos de una playa urbana del oriente venezolano. <em>Ciencia e Ingeniería</em>, 9 (1): e6706296. https://www.doi.org/10.5281/zenodo.6706296</p>
Emite Playa San Blas
Este elemento de hormigón prefabricado se utiliza para enterrar emisarios bajo la arena (tuberías que expulsan aguas residuales al mar). Su función es el de proteger a la tubería frente a temporales o impactos. Se desconocen las causas por los que este "emite" se encontraba en el centro de lo que debió ser un parche de sebadal, barajamos como hipótesis la pérdida de la pieza durante el transporte. Profundidad: 10 metros Número fotografías: 110 fotos Condiciones de trabajo: buenas, sin corrientes y visibilidad 15 metros. Dimensiones: 2 metros de ancho por 1,5 de largo por 1 metro de alto.

Luquillo Experimental Forest site, station Luquillo Forest Dynamics Plot at El Verde, study of animal abundance of Oleacina playa in units of numberPer1130m2 on a yearly timescale
The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Luquillo Experimental Forest (LUQ) contains animal abundance of Oleacina playa measurements in numberPer1130m2 units and were aggregated to a yearly timescale.
