Spatial and Temporal Availability of Cloud-free Optical Observations in the Tropics
<p>These data comprise three layers describing the spatial and temporal distribution of cloud-free optical observations over the tropics. The test datasets shared here are derived from the combination of Landsat and Sentinel-2 satellite data and represent a portion of the full datasets. The test data correspond to year 2020 over Mesoamerica. </p> <ul> <li>Spatial data: the Meso2020_validObs contains one band 'valid_obs' indicating the number of cloud-free observations at the pixel level. </li> <li>Temporal data: the maximumWaitDate2020 contains two bands 'max' and 'maxDay' corresponding to the number of maximum consecutive days without data in a year and final date in which the maximum number of consecutive days without data occurred, respectively.</li> </ul>

Spatial and temporal patterns of habitat use and availability in upper Coweeta Creek from 1996 to 1998
I collect data describing total depth, mean current velocity and substrate characteristics (% - silt, debris, sand, gravel, cobble, boulder and bedrock) at 100 random points along 1 m transects within each 100 m site. Data are collected seasonally to investigate spatial and temporal patterns of habitat variability in upper Coweeta Creek. Flow data will be used to elucidate whether changes in habitat characteristics are correlated with high flow events.
Data from: Temporal change in floral availability leads to periods of resource limitation and affects diet specificity in a generalist pollinator
<p class="Default"><span>Generalist species are core components of ecological networks and crucial for the maintenance of biodiversity. Generalised species and networks are expected to be more resilient, therefore understanding the dynamics of specialisation and generalisation in ecological networks is a key focus in a time of rapid global climate change. Whilst diet generalisation is frequently studied, our understanding of how it changes over time is limited. We explore temporal variation in diet specificity in the honeybee (<em>Apis mellifera</em>), using pollen DNA metabarcoding of honey samples, through the foraging season, over two years. We find that overall, honeybees are generalists that visit a wide range of plants, but there is temporal variation in the degree of specialisation. Temporal specialisation of honeybee colonies corresponds to periods of resource limitation, identified as a lack of honey stores. Honeybees experience a lack of preferred resources in June when switching from flowering trees in spring to shrubs and herbs in summer. Investigating temporal patterns in specialisation can identify periods of resource limitation that may lead to species and network vulnerability. Diet specificity must therefore be explored at different temporal scales in order to fully understand species and network stability in the face of ecological change.</span></p>

Figure 2 Percentage contribution SIMPER of items in the gut contents of the Nacella species in Puerto del Hambre and Otway Sound for the winter and summer months. The contribution limit was 90% of the total dietary composition. SIMPER analysis shows the dissimilarity between the species of Nacella in the two localities (average dissimilarity in bold and on the bar). The contribution limit was 75% of the total dietary composition. M = Macroalgae (with colours) and I = Invertebrates (with grey scale). Structural hardness of the thallus for macroalgae: th = thin filaments, cf = corticated filaments, clf = cylinder-like form and lm= leathery macrophyte. Functional group for invertebrates: s = sessile and m = mobile.
