Large seeds provide an intrinsic growth advantage that depends on leaf traits and root allocation
<p>Seed mass and growth rate are important dimensions of plant ecological diversity, but their relationship remains unresolved. Negative relationships between relative growth rate (RGR) and seed mass are well established. However, RGR is size-dependent, so small-seeded species might achieve fast growth simply because they are initially small.</p> <p>Using a dataset of unprecedented size, sampling 382 grass species, we investigated seed mass and growth rate using both RGR and SGR (RGR at a specific size), accounting for diversity in phylogeny, ecology (e.g. life history, photosynthetic pathway) and environment (mean annual temperature and precipitation).</p> <p>RGR and SGR showed contrasting relationships with seed mass, such that large-seeded species had lower RGR but higher SGR than small-seeded species. However, the relationship between SGR and seed mass depended on leaf dry matter content (LDMC), and was only positive in high-LDMC species. When compared at a common size, the fast growth of large-seeded and low-LDMC species was associated with greater biomass allocation to roots in the hot, high-light environment used for our experiment. Photosynthetic pathway and life history contributed to variation in SGR, with C4 annuals having higher SGRs than C3 perennials regardless of seed size.</p> <p>Large seeds therefore afford an intrinsic growth advantage in species with resource-conserving leaf traits, and may provide a competitive edge in resource-poor environments. This work advances understanding of how seed mass and growth rate coevolve with other ecological factors.</p>

Data from: Intrinsic traits of woodland caribou Rangifer tarandus caribou calves depredated by black bears Ursus americanus and coyotes Canis latrans
Individuals in substandard physical condition are predicted to be more vulnerable to predation. Support for this prediction is inconsistent partly as a result of differences across systems in the life histories of predator and prey species. Our objective was to examine the physical condition of woodland caribou (Rangifer tarandus caribou) calves depredated by two predators with different life histories in Newfoundland, Canada. Black bears (Ursus americanus) are capable of chasing calves at high speeds over short distances and primarily prey on calves <1 month of age. Coyotes (Canis latrans) are cursorial predators that pursue prey over longer distances, which is expected to result in the selection of substandard individuals. We hypothesized that (i) black bears will kill calves in substandard physical condition, while (ii) coyotes will kill calves from across the distribution of individual conditions. We used mitochondrial DNA species identification tests to assign predator species to calf mortalities. We then used molecular identifications and field observations to build a predictive model using generalized boosted trees to predict the predator species where a molecular identification was unavailable. We tested our hypotheses using Cox proportional hazards models under a competing risks framework. Bears killed younger calves and lighter calves, while coyotes killed heavier calves. Coyotes also killed more late-born calves, which might suggest prey switching as calves become more abundant later in the season. Our findings suggest that the physical constraints of predators play a greater role than predator hunting strategies in this system, but other processes are likely influential. The tendency for coyotes to kill heavier calves might result from sustained coyote predation over time, following the removal by black bears of lighter calves during their first month of age. This research illuminates the complexity of predator-prey interactions in Newfoundland and highlights an important source of variability for predator-prey systems.

Exploring causal components of plasticity in grey seal birthdates: effects of intrinsic traits, demography, and climate
<p>Change in breeding phenology is often a response to environmental forcing, but less is known of the mechanism underlying such changes and their fitness consequences. Here we report on changes in the breeding phenology from a 27-year longitudinal study (1991-2017) of individually marked, known-aged grey seals (Halichoerus grypus) on Sable Island, Nova Scotia, Canada.</p> <p>We used Generalized Linear Mixed Models to test hypotheses about the influence of fixed factors (maternal age, parity, previous reproductive success, pup sex, colony density, AMO, NAO, and SST) and a random factor (female identity) on parturition dates. We also examined the consequences of the shift in birthdates on maternal energy investment in offspring as measured by pup weaning mass. Birthdates were known for 2768 pups of 660 known-age females. For 494 females with ≥ 2 parturition dates, repeatability as measured by the intraclass correlation was high (mean=0.66). 87% of the variation in birthdates was explained by a mixed effects model that included intrinsic and extrinsic fixed effects. Most of the explained variation was associated with the random effect of female identity.</p> <p>Parity was the most important intrinsic fixed effect, with inexperienced mothers giving birth later in the season than multiparous females. Over almost 3 decades, mean birthdates advanced by 15 days. The mixed model with intrinsic effects and population size, the detrended AMO from the previous year and mean NAO in the previous 3 years explained 80 % of the variation with 21 % of variation from the fixed effects. Both primiparous and multiparous individuals responded to the climate forcing, and there was strong evidence for heterogeneity in the response. The shift in birthdates did not impact pup weaning mass. Females exhibited considerable phenotypic plasticity indicating that climate driven changes in breeding phenology may not always have measurable consequences.</p>
