Figure 4 in Calling phenology of anurans in a tropical rainforest in South Mexico: testing predictive models
Figure 4. Best models of each general structure. Model 6 (M6) for linear and 13 (M13) for sinusoidal structure. I = relative calling intensity, t = time. The solid lines represent the predictions of the models; the points represent the data acquired from the ARS.

Figure 3. Rose-diagram of anuran assemblage relative calling intensity. The length and colour (light = low, dark = high) of the bars from the centre indicate the intensity of vocalisation for the temporal section. A Rayleigh z test for unimodal orientation was performed, resulting in significant evidence of non-uniform distribution of vocalisations across the year (P = 0.0303).

Castela senticosa (Simaroubaceae: Sapindales), a new species from the Caribbean clade endemic to seasonally dry tropical forest on Hispaniola
<p>Recent fieldwork in the Sierra Martín García in southwestern Dominican Republic has yielded a new species of the American clade <i>Castela</i> (Simaroubaceae), <b><i>Castela senticosa</i></b> sp. nov., from seasonally dry tropical forest. This species has been collected from two separate localities, including Môle St. Nicolas in northwestern Haiti in 1929, but until now fertile material with both flowers and fruit was unknown. We provide a photographic plate and illustration, place it phylogenetically using plastome data, and compare it morphologically with close relatives. This increases the number of known species of <i>Castela</i> on Hispaniola from one to two, both of which are endemic but from different clades, and yields another species for the Greater Antilles, a known biodiversity hotspot and clear center of diversification for this group of arid-adapted, thorny shrubs. This work emphasizes that seasonally dry tropical forest, although often understudied, house as yet undiscovered biodiversity and deserve far more comprehensive studies.</p>

Exceptionally high apparent adult survival in three tropical species of plovers in Madagascar
<p>Adult survival is a key component of population dynamics and understanding variation in and the drivers of adult survival rates and longevity is critical for ecological and evolutionary studies, as well as for conservation biology and practice. Tropical species of landbirds are often selected to have higher adult survival due to high nest predation rates, but it is unclear if the same patterns occur in other avian lineages with different life history strategies. Here, we investigate adult survival of three sympatrically breeding species of shorebirds in south-west Madagascar: the endemic and endangered Madagascar Plover <i>Charadrius thoracicus</i>, and two more widely distributed African species: the White-fronted Plover <i>C. marginatus</i> and the Kittlitz's Plover <i>C. pecuarius</i>. Using mark-recapture data from 1843 individuals breeding at an intensely monitored saltmarsh over a 13-year period, we estimated annual rates of apparent survival (φ) corrected for encounter probability. Adult apparent survival rates were high for all three species (mean ± SE): Madagascar (φ<i> </i>= 0.899 ± 0.010) and White-fronted Plovers (φ = 0.923 ± 0.008). Kittlitz's Plovers showed a difference between the first (φ<sup>1</sup> = 0.719 ± 0.026) and subsequent transitions (φ<sup>2+</sup> = 0.892 ± 0.014), suggesting that transient breeders are common in this species. For birds first captured as adults, these survival estimates translate to life-expectancies of 9.72 (± 1.11) years in Kittlitz's plovers, 9.36 (± 0.98) years in Madagascar Plovers and 12.48 (± 1.32) in White-fronted Plovers. We hypothesise that long lifespan could be an adaptation arising from the unique climatic pressures on the island of Madagascar that would otherwise lead to reduced fitness. However, long lifespans may not sufficiently compensate for a reduction in breeding opportunities due to possible climatic disruption in the future. Consequently, at least two of these plover species seem vulnerable to ongoing habitat destruction and changing climate cycles.</p>
