Long-term comparison of the euglossine community
<p>Global bee decline and its impact on pollination in agricultural and natural ecosystems have attracted public attention. However, more data are needed to show their generality and intensity in different ecosystems, especially in the tropics. For centuries, the tropical dry forest (TDF) of Costa Rica underwent intense deforestation, but in the last four decades, a large part of this forest has entered a recovery process. Using data of orchid bees generated by Janzen et al. (1982) in TDF in the Santa Rosa sector of the Guanacaste Conservation Area (ACG), we posed a general question: What changes have occurred in diversity, composition, and seasonality of the euglossine bee community in the TDF during the last 40 years and how are these changes related to the current recovery of this forest. We sampled euglossine bees during 2018-2019 using methods similar to those applied previously. To characterize the response of euglossine bees to habitat loss, we extended the sampling to pastures adjacent to the protected area. With the loss (n=4) and gain (n=3) of bee species, we did not find significant changes in overall species richness between now and 40 years ago. However, the composition of the euglossine community in the protected area in 1977 was more similar to that found in current pastures than to the current community in forests, where the presence of forest-dependent species has been favored. It is possible that TDF regeneration in Santa Rosa has led to changes in the composition of the community of these bees.</p>

Figure 2 Wear and ovarian development of adult females caught in spring and summer. Fisher exact tests were used to compare the proportions of spring and summer females in each ovarian category. Unworn summer females with no ovarian development were excluded, as these females likely were newly eclosed. In L. laevissimum and L. hitchensi, spring females were significantly more likely to be fecund (largest oocyte at least 1/2-developed), while in L. ellisiae, spring and summer females showed similar levels of ovarian development (see Table 3 for statistics).

Figure 1 Bivoltine flight phenologies of L. laevissimum, L. hitchensi and L. ellisiae, inferred from pan trap collections, 2003–2013. The number of bees collected per week represents the average number of bees collected in pan traps, across sites and years, from 2003 to 2013. A total of 52 L. laevissimum bees, 1480 L. hitchensi bees, and 67 L. ellisiae bees were collected. Dark grey bars represent males, white bars represent spring females and light grey bars represent summer females. The red polynomial regression (drawn using the geom_smooth function, Loess method, in R) was used to help visually identify the number of abundance peaks for each species. Black arrows indicate the weeks when L. hitchensi males were collected in pan traps.

Long-term shifts in the functional diversity of abandoned wet meadows – Impacts of historical disturbance and successional pathways
<p>Investigating the direction of changes in functional diversity involving successional pathways and historical disturbances may be a promising tool for predictions of the effectiveness of the semi-natural meadows conservation, with great emphasis on formulation of more cost-effective restoration strategies. The goal of this research was to assess the differences in long-term shifts in the functional diversity of plant species in semi-natural wet meadows unmanaged for the last 40 years, under the influence of different successional pathways and historical disturbances. Using ordination techniques, linear mixed-effect models, a set of plant functional traits and parameters of functional diversity, we assessed the importance of habitat filtering, competition and niche partitioning in shaping community assembly changes over time. The most dramatic shifts in functional diversity were found in the <i>Carex acutiformis </i>successional pathway after topsoil removal, where colonization by successional inhibitors was the main driver causing decreases in functional dispersion and divergence. This was expressed as a decrease in the importance of habitat filtering and replacement of specialized species by competitors with heavier seeds and higher specific leaf area. Regarding the <i>C. cespitosa</i> and <i>Salix cinerea </i>pathways, the magnitudes of shifts in functional diversity were milder and differed less between the historical topsoil removal and mowing treatments, thereby maintaining a large role for niche partitioning in shaping the vegetation structure. The results of our study highlight the importance of tussock sedges and shrubs as effective buffers against the biotic homogenization of meadows driven by the simplification of functional composition, even from a long-term perspective.</p>

Verification of the accuracy of the recent 50 years of tree growth and long-term change in intrinsic water-use efficiency using xylem Δ14C and δ13C in trees in an aseasonal tropical rainforest
<p>Growth analysis based on tree-ring chronology is difficult in trees in aseasonal tropical rain forests, because annual growth rings may be unclear or completely absent. Fortunately, tree growth history recorded in xylem tissue is capable of providing valuable information on the responses of trees and forests to past and present environmental changes, including global warming.</p> <p>We have developed a new technique for aseasonal tropical forest trees which derives their growth rates from xylem Δ<sup>14</sup>C, and verified its accuracy. We also determined, from xylem δ<sup>13</sup>C, the intrinsic water-use efficiency (iWUE) in the past 50 years. We analyzed changes in xylem Δ<sup>14</sup>C and δ<sup>13</sup>C in 23 canopy trees of 12 species in 6 families growing in Pasoh Forest Reserve, Malaysia; each stem diameter at breast height (DBH) was recorded 14 times from 1969 to 2011.</p> <p>We found a significant positive relationship between the growth rates determined by <sup>14</sup>C dating and the past DBH data. On the other hand, leaf-internal CO<sub>2</sub> (C<sub>i</sub>) content did not change with increasing atmospheric CO<sub>2</sub> (C<sub>a</sub>). Thus, the iWUE increased significantly over the last 50 years in all the families and species tested.</p> <p>This study showed that the simultaneous measurements of xylem Δ<sup>14</sup>C and δ<sup>13</sup>C could reveal a long-term change in tree growth and iWUE during the past 50 years with high accuracy in various species and/or individuals in aseasonal tropical rainforests exhibiting high species diversity.</p>
MeadoWatch: a long-term community-science database of wildflower phenology in Mount Rainier National Park
<p>We present a long-term and high-resolution phenological dataset from 17 wildflower species collected in Mt. Rainier National Park, as part of the MeadoWatch (MW) community science project. Since 2013, 500+ unique volunteers and scientists have gathered data on the timing of four key reproductive phenophases (budding, flowering, fruiting, and seeding) in 28 plots over two elevational gradients alongside popular park trails. Trained volunteers (87.2%) and UW scientists (12.8%) collected data 3-9 times/week during the growing season, using a standardized method. Taxonomic assessments were highly consistent between scientists and volunteers, with high accuracy and specificity across phenophases and species. Sensitivity, on the other hand, was lower than accuracy and specificity, suggesting that a few species might be challenging to reliably identify in community-science projects. Up to date, the MW database includes 42,000+ individual phenological observations from 17 species, between 2013 and 2019. However, MW is a living dataset that will be updated through continued contributions by volunteers, and made available for its use by the wider ecological community.</p>

Long-term outcomes and prognostic factors in kidney transplant recipients in Jakarta, Indonesia: a cohort study
<p><strong>Objectives </strong>To determine the long-term survival rates and prognostic factors in kidney transplant (KT) recipients in Jakarta, Indonesia.</p> <p><strong>Design</strong> Retrospective cohort study.</p> <p><strong>Setting</strong> A KT centre in Jakarta.</p> <p><strong>Participants</strong> We enrolled 754 consecutive adult recipients who underwent KT between 2010 and 2020.</p> <p><strong>Main outcome measures </strong>Rates of 10-year patient, all-cause and death-censored graft survival and their prognostic factors in KT recipients.</p> <p><strong>Results </strong>The 10-year patient survival, all-cause survival and death-censored graft survival rates of KT recipients were 74%, 68% and 81%, respectively. The prognostic factors for poor patient survival were a pretransplant dialysis duration>24 months (HR 1.64, 95% CI, 1.08 to 2.49; p=0.02), cardiovascular disease (HR 1.59, 95% CI, 1.11 to 2.31; p=0.01), delayed graft function (DGF) (HR 4.94, 95% CI, 2.76 to 8.82; p<0.001), post-transplant infection (HR 2.63, 95% CI, 1.56 to 4.43; p<0.001) and acute rejection (HR 2.49, 95% CI, 1.20 to 5.15; p=0.01). All-cause graft survival was prognosticated by a pretransplant dialysis duration>24 months (HR 1.74, 95% CI, 1.15 to 2.47; p=0.007), cardiovascular disease (HR 1.65, 95% CI, 1.18 to 2.33; p=0.004), DGF (HR 5.39, 95% CI, 3.13 to 9.28; p<0.001), post-transplant infection (HR 2.46, 95% CI, 1.05 to 4.02; p<0.001) and acute rejection (HR 4.18, 95% CI, 2.23 to 7.84; p<0.001). Factors associated with poor death-censored graft survival were a pretransplant dialysis duration >24 months (HR 2.19, 95% CI, 1.32 to 3.63; p=0.002), cardiovascular disease (HR 1.65, 95% CI, 1.02 to 2.68; p=0.04) and acute rejection (HR 5.52, 95% CI, 2.80 to 10.83; p<0.001).</p> <p><strong>Conclusions </strong>The survival rates of KT recipients are prognosticated by pretransplant dialysis duration, cardiovascular disease, DGF, post-transplant infection and acute rejection. Stricter eligibility criteria for recipients, more sensitive cross-match testing methods and better infection management strategies may be beneficial for improving the survival rates.</p>
