Fundamental niche narrows through larval stages of a filter-feeding marine invertebrate
<p>Ontogenetic niche theory predicts that resource use should change across complex life histories. To date, studies of ontogenetic shifts in food niches have mainly focused on a few systems (e.g. fish), with less attention on organisms with filter-feeding larval stages (e.g. marine invertebrates). Recent studies suggest that filter-feeding organisms can select specific particles, but our understanding of whether niche theory applies to this group is limited. We characterised the fundamental niche (i.e. feeding proficiency) by examining how niche breadth changes across the larval stages of the filter-feeding marine polychaete <em>Galeolaria</em> <em>caespitosa</em>. Using a no-choice experimental design, we measured feeding rates of trochophore, intermediate-stage and metatrochophore larvae on the prey phytoplankton species: <em>Nannochloropsis</em> <em>oculata</em>, <em>Tisochrysis</em> <em>lutea</em>, <em>Dunaliella</em> <em>tertiolecta</em> and <em>Rhodomonas</em> <em>salina</em>, that vary 10-fold in size, from the smallest to the largest. We formally estimated Levins' niche breadth index to determine the relative proportions of each species in the diet of the three larval stages and also tested how feeding rates vary with algal species and stage. We found that early stages eat all four algal species in roughly equal proportions, but niche breadth narrows during ontogeny, such that metatrochophores are feeding specialists relative to early stages. We also found that feeding rates differed across phytoplankton species—the medium-sized cells (<em>Tisochrysis</em> and <em>Dunaliella</em>) were eaten most, and the smallest species (<em>Nannochloropsis</em>) was eaten the least. Our results demonstrate that ontogenetic niche theory describes changes in fundamental niche in filter feeders—an important next step is to test whether the realized niche (i.e. preference) changes during the larval phase as well.</p>

Invertebrate abundance sampled by benthic trawl and grab from common sites
<p><strong>Aim</strong>: Long-term monitoring of offshore benthic communities provides data which are essential for effective marine management. Due to the expense and difficulty of sampling the seafloor comprehensively, monitoring is often limited to one sampling method targeting a specific community. In these cases, biological surrogacy is a useful monitoring approach and can be based on more easily sampled community diversity indices or assemblage patterns across the monitoring sites. This study aimed to quantify marine benthic invertebrate cross-community congruence and test surrogate effectiveness.</p> <p><strong>Location</strong>: Southern Benguela Shelf ecoregion on the west coast of South Africa.</p> <p><strong>Methods</strong>: We compared two benthic biological datasets collected from the same 24 sites: epifauna sampled by demersal research trawl and infauna sampled by grab. This study utilised co-correspondence analysis (CoCA) to test for congruence in assemblage patterns between communities and test community surrogacy.</p> <p><strong>Results</strong>: Significant linear relationships were found between epifauna and infauna species abundance, richness (d), and diversity (H'log<sub>e</sub>). Symmetric co-correspondence analysis (sCoCA) found the common variance captured by the first four axes to explain 40% and 24% of the total epifauna and infauna assemblage variation, respectively. Environmental gradients played a key role in structuring these similarities in broadscale biodiversity patterns. Predictive co-correspondence analysis (pCoCA) showed that epifauna assemblage structure did not significantly predict infauna assemblage structure, but infauna did predict 14% of the variation in epifauna assemblage structure.</p> <p><strong>Main conclusions</strong>: Epifauna and infauna communities were structured similarly but do not predict each other; community congruence does not imply effective surrogacy. These findings should be considered when including different benthic biological datasets into ecosystem classification and mapping, and provides a statistical framework for testing community congruence and surrogate effectiveness.</p>

F I G U R E 1 in The nutritional importance of invertebrates to female Cebus capucinus imitator in a highly seasonal tropical dry forest
F I G U R E 1 The (a) monthly fruit energy density versus the monthly percentage of energy intake from invertebrates for all female capuchins studied and (b) group-level linear regression results between ripe fruit energy density and the percentage of energy intake from invertebrates (log transformed) for our three capuchin study groups. One outlier month (> 2 SD from the mean) was removed from the intergroup analysis
F I G U R E 3 in The nutritional importance of invertebrates to female Cebus capucinus imitator in a highly seasonal tropical dry forest
F I G U R E 3 Mean contribution of fruit and invertebrates to the (a) estimated daily energy intake and (b) protein intake per body weight per day. The dotted red line indicates monthly estimated (a) energy intake based on the estimated 1,000 kJ/day and (b) protein requirements based on the 1.8 g/kg/day. The dotted black line represents the estimated requirements for lactating females, which are estimated to require 1.5 times more (a) energy and (b) protein than cycling females. Minimum energetic and protein requirements are often not met by consuming fruit alone but are when invertebrates are included, particularly for lactating females. Although data are presented to reflect a calendar year, data were collected in three separate periods between 2009 and 2011
