Behavior of Nannopterum brasilianus (Gmelin, 1789) (Suliformes: Phalacrocoracidae) in an urban park in the municipality of Uberlândia, Minas Gerais State

Biotemas, 2019
The modification of landscapes by anthropic action, mainly due to urbanization, exerts strong pressure on birds. Public parks and other green areas offer favorable conditions for birds in cities throughout the year. Nannopterum brasilianus (Gmelin, 1789)

Habitat heterogeneity influences avian feeding guild composition in urban landscapes: evidence from Bhubaneswar, India

Ecological Processes, 2021
Background Habitat heterogeneity clearly distinguished in terms of availability of food and habitat resources and landscape features (natural or human-modified) play a crucial role in the avian species composition and population structure.

Tapeworm Parasite Burden Is Linked to Diet, Body Size, Condition, Growth, Restocking and Habitat Use in Piscivorous Salmonids of a Subarctic Lake

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Parasites affect hosts in interaction with the entire ecological community. This is particularly evident for trophically transmitted parasites, such as Dibothriocephalus tapeworms, which infect multiple intermediate fish hosts, potentially reducing their fitness and suitability for human consumption.

Functional Variation in the Feeding Apparatus of Charadriiform Shorebirds With Emphasis on Bill‐Tip Organs and Micro Tongue Tip Spines

Journal of Morphology, Volume 287, Issue 9, September 2026.
Comparative morphological analyses of shorebird feeding apparatus revealed substantial variation in bill‐tip organs and micro tongue tip spines across taxa. Key findings included variation in sensory pit numbers within the bill‐tip organs characteristic of Scolopacidae, and scanning electron microscopy (SEM) revealing micro tongue tip spines in several

Initial colonization by bryophytes and ferns during primary succession on Nishinoshima, Japan

Nordic Journal of Botany, Volume 2026, Issue 9, September 2026.
Volcanic islands that have experienced complete vegetation loss following recent eruptions provide rare opportunities to observe the earliest stages of ecosystem recovery. Nishinoshima, an oceanic island located approximately 1000 km south of mainland Japan, underwent major volcanic activity between 2013 and 2020, eradicating all pre‐existing ...

Functional Diversity of Iberian Waterbird Communities From Natural Lakes and Man‐Made Reservoirs Shows Divergent Temporal Dynamics

Diversity and Distributions, Volume 32, Issue 9, September 2026.
ABSTRACT Aims Artificial waterbodies are widely recognized as vital habitats for waterfowl conservation, particularly in the Mediterranean region, where natural lentic ecosystems have suffered extensive loss and degradation. Man‐made reservoirs represent the widespread and relatively deep artificial bodies of water and are often assumed to harbour poor

Interannual Variations in Distribution and Density of Japanese Anchovy (Engraulis japonicus) Larvae in the Shelf‐Break Region of East China Sea During Spring (2001–2022)

Fisheries Oceanography, Volume 35, Issue 5, Page 777-794, September 2026.
ABSTRACT Japanese anchovy (Engraulis japonicus) is the most abundant fish in the East China Sea (ECS) and an important fishery resource throughout its life stages. Using samples collected along the ECS shelf‐break in April over a 22‐year period (2001–2022), we examined the horizontal distribution and interannual variability of larval density (mean ...

First report of albinism in the South American catfish Imparfinis mirini (Siluriformes: Heptapteridae)

Revista Mexicana de Biodiversidad, 2017
Albinism is a genetic condition caused by an autosomal recessive gene that affects normal pigmentation in animals. In Neotropical freshwater fish fauna, albinism cases are extremely rare, with only 14 species recorded among more than 6,000 described ...

Sex‐specific prey partitioning in breeding piscivorous birds examined via a novel, noninvasive approach [PDF]

Ecology and Evolution, 2018
AbstractPiscivorous birds frequently display sex‐specific differences in their hunting and feeding behavior, which lead to diverging impacts on prey populations. Cormorants (Phalacrocoracidae), for example, were previously studied to examine dietary differences between the sexes and males were found to consume larger fish in coastal areas during autumn
